Ethernet Access Devices (EAD) MARKET Report- released April 18, 2013
“People keep saying that copper’s dead, but it’s not—it has a limited but important role for Ethernet services, as evidenced by the continued growth of EFM (Ethernet in the first mile) bonded copper,” notes Michael Howard, principal analyst for carrier networks and co-founder of Infonetics Research. “EFM’s high capacities and reach make it a useful and effective alternative where fiber isn’t justified.”
- For the full year 2012, the global Ethernet access device (EAD) market grew 3.5%, to $860 million, with growth hesitating as a result of economic conditions and a lull in carrier spending in the 2nd half of 2012
- 10/100M copper and 1G fiber dominate EAD ports today, but 10G fiber is growing fast, forecast by Infonetics to grow at a 117% CAGR through 2017
- Though in slow decline, Ethernet over TDM (EoTDM) bonded circuits will remain a niche market, providing an inexpensive way to combine several E1s or T1s
- For the second consecutive year, the top 5 revenue share leaders in the EAD market are (in alphabetical order) Actelis, ADVA, Ciena, Overture, and RAD

Early History of Ethernet:
According to Bob Metcalfe: “The first Ethernet was a one-node Ethernet, which isn’t very interesting. It was a node that could transmit to itself for testing and de-bugging purposes. Then we had two nodes – which incidentally we called Michelson and Morley who happened to be the two physicists who disproved the existence of the ether, so we thought that was ironic – then eventually the cable got strung all over the building.”
What was the real innovation, as they saw it then? “In those days our big innovation was putting a computer on every desk – I know that’s hard to believe! We put one on every desk then ran this co-ax down the middle of the corridor and everybody tapped into it from their PCs. So it grew to fill this building.”
The benefits were immediate, and so other departments wanted in on the network. “The labs wanted to be connected so, with an Internet protocol, we built an Internet that spanned the research laboratories of Xerox. It wasn’t until the late seventies that we began leaving Xerox and installing Ethernets elsewhere.”
Bob Metcalfe (shown below) went on to found 3Com, makers of the first Ethernet commercial Ethernet cards. Within 20 years Ethernet saw off competition from token-based networking and came to dominate the LAN space, covering every continent with islands of Ethernet connectivity.
Role of XEROX PARC:
Heir to this great tradition is Steve Hoover, the current CEO of PARC. He points out the importance of an open spirit of enquiry to balance the intense commercial pressure to deliver results: “One of the key things is recognising that innovation is going to require failure. So you can’t start something and not believe that it’s possible to fail…. Of course it’s not about failing, failing’s not good, but it’s about learning.”
Steve compares this innovative culture to a class of five-year olds: “It’s all the questioning … It’s why, why, why! That leads to really good innovation because people are getting to the fundamental ideas, they’re questioning the status quo, they’re willing to change it and break it. Fail on the way and then pick yourself up, dust yourself off and move on to the next.”
Vital Contributions of Government and Academia:
A key element of the 40th birthday celebrations will be discussion around the need to foster and maintain this dynamic spirit of innovation in today’s globally competitive environment. This goes beyond a purely business concern, innovation is vital to national pride and prosperity – even to survival. It is, therefore a concern for governments too.
Steve Hoover points out that the business world sometimes forgets the contribution made by past governments: “If you look back at the history of the Internet, Arpanet was government-initiated. The tremendous commercial
“If you look back at the history of the Internet, Arpanet was government-initiated. The tremendous commercial impact I don’t believe would have occurred without their foresight in investing in those fundamental capabilities.”
“Today at PARC we are working to repeat that model over and over and over again.” Steve is very keen to enroll government support for this work, pointing out the need to recognize that: “The government does identify fundamental research areas to work in and is willing to invest. That partnership – of government investing in core capabilities, in new areas, taking some of the higher risk, plus industry’s ability to capitalise and leverage it – that partnership is really important.”
Metro Ethernet Forum (MEF) and Carrier Ethernet:
Over the last 10 or 11 years, IEEE 802.3 Ethernet First Mile, the MEF and the ITU-T developed solid standards for Carrier Ethernet. These specs were developed to enable "islands of data" to be connected via Ethernet, rather than more complex and costly WAN technologies such as Frame Relay and ATM. Last year marked a turning point: for the first time Carrier Ethernet sales exceeded that of all other WAN technologies combined.
As MEF President Nan Chen once predicted: “In future there will be a single language linking business worldwide. It won’t be English. It won’t be Mandarin. It will be Ethernet”.
The Future of Ethernet:
Bob Metcalfe says that networking and the Internet has given this generation “collective intelligence” and so much more to play with in terms of access to all that has already been achieved, both the successes and the failures of the past and present. So who knows what form Ethernet’s 50th anniversary will take in ten years time?

Market research firm Infonetics Research released excerpts from its latest Data Center Deployment Strategies: Global Service Provider Survey, which delves into operator plans for data center expansion, interconnection, capacity, physical servers, virtualization, and SAN and storage technologies.
DATA CENTER SURVEY HIGHLIGHTS:
. More operators than anticipated plan to continue investing in Fibre Channel for their data centers, even in the face of growing usage of the newer Fibre Channel over Ethernet (FCoE)
. The number of data center server LAN connections is growing quickly, with 10 Gigabit Ethernet connections growing the most
. The average capacity of a data center WAN connection is expected to increase more than twofold from 2012 to 2014
. While the use of virtual machines in data centers continues to grow, many servers are not yet virtualized
DATA CENTER SURVEY SYNOPSIS:
For its 23-page data center survey, Infonetics interviewed incumbent and competitive service providers and cloud specialists that have data centers with at least 100 servers. The survey provides insights into data center interconnection strategies; storage network investments; data network technologies deployed; WAN/internet connection capacities; and number of physical servers, virtual machines, Ethernet and SAN interfaces in use at medium, large, and super data centers.
"Server virtualization has been the focus of the data center industry for several years now, and the largest data center owners and internet content providers like Google are ubiquitously exploiting virtual machines," notes Michael Howard , principal analyst for carrier networks and co-founder of Infonetics Research. "Yet the reality is the bulk of data center owners are more pedestrian in their deployments, finding it more operationally convenient to leave many areas of their data centers alone, using server virtualization for only select applications."
Howard continues: "But to be sure, data center owners want to increase the value of their existing data center assets - no matter the extent of server virtualization - as a means to increase revenue via cloud services, both to keep their current customers satisfied and to attract new customers."

Commenting on the new interest in network virualization and Software Defined Networking (SDN), Howard said at the April 3rd Ethernet Technology Summit:
"Network operator driver for NFV is quick revenue (via faster provisioning of new services and telecom facilities).” He later stated, "Carriers will implement SDN in ‘contained domains."
“Moore’s Law has transcended computing expectations; however, its promise will eventually reach scalability limitations due to extraordinary consumer demands. Future technology encompasses breakthroughs capable of interaction with the outside world, which the "More than Moore" movement achieves. Through integrating functionalities that do not scale to deliver cost-optimized and value-added system solutions, this trend holds significant potential for the industry. This event will explore the business and technical factors defining the More than Moore movement, and address how it will yield revolutionary electronic devices.”

- Many of the functions that have to be integrated into devices are analog/RF where Moore's Law does NOT apply!
- Mixed signal technologies (combining analog and digital circuits in a single chip/module) need to continue to advance to include those functions along with typical baseband and DSP on the same chip/module.
- Packaging technology will be critically important- both at the component/module and systems level. Innovation and "out of the box thinking" here are very much needed.
- Testing at the package and system level will also be important.
- For the IoTs, the following I/O improvements are needed for devices/networked sensors: short reach, very low power, variable bit rate (low to high), support of multiple wireless standards (e.g. Blue Tooth, Zigbee, Low Power WiFi, etc)
- A new way of designing analog ICs needs to be considered for the IoT to be a mass market.
- A key question here is "how much further can the industry convert (inherently) analog functions to digital and then use DSPs to implement them?"
- Many of the mobile computing functions will be implemented by servers in a cloud resident Data Center. For those servers, interconnects on the circuit board could be the limiting factor in reducing cost and power.
“It’s natural for MEMS and mixed-signal devices, or MEMS and logic devices, to live in a side-by-side (2.5D) world.”
“Organic substrates for 2.5D interposers show great promise for reducing 2.5D interposer costs – look particularly to the work being done by Georgia Tech.”
“If you don’t follow scientific change then what you practice reverts to witchcraft.” (The Rabinovitsi Paradigm.)
“Innovation in packaging may be more relevant than Moore’s Law moving forward.”
“3D packaging is becoming a very exciting technology, with as much relevance as a process node shift.”
“The IoT needs packaging innovations – not Moore’s Law technology progression.”
“FinFET or packaging – where’s the smart money playing? The problem is one of die / device performance versus system performance – and packaging drives system performance.”
“That being said, 3D packaging is not a panacea – basic economics still rule.”
“Seven years from now it will be IoT applications driving the industry – and Moore’s Law progress doesn’t apply to the analog world, hence the need to work on heterogeneous integration / 2.5D / 3D IC."
“New generations of network-side IC products are only 15% innovation – the other 85% is composed of standard I/O and memory IP. Moving some of that 85% from the board to the interposer or to a 3D stack will be a huge performance improvement - 3D memory integration, for example, is positively disruptive.”
“But doesn’t CMOS integration always win? Monolithic integration, or heterogeneous integration using 2.5D / 3D IC; either way it comes together, no one size fits all.”
“The 28nm process node has a lot to like about it: speed, cost, High Volume Manufacturing (HVM) capability, and IP portability all look good compared to 14nm FinFET.”
“Challenges that need addressing in 2.5D / 3D IC are supply chain related. The current cost structure for 2.5D / 3D is leveraged by materials and processing equipment.”
“Do we currently even have a functioning 3D IC ecosystem?”
“Thermal challenges have kept 3D IC from coming to the mainstream. 2.5D is much better than 3D from a thermal perspective.”
Level 3 Communications (NYS: LVLT) reported earnings on April 25. For the quarter ended March 31 (Q1), Level 3 Communications missed slightly on revenues and missed expectations on earnings per share. Margins expanded across the board. Level 3 Communications tallied revenue of $1.58 billion. The 14 analysts polled by S&P Capital IQ hoped for revenue of $1.61 billion on the same basis. GAAP reported sales were the same as the prior-year quarter's.
Source: S&P Capital IQ. Quarterly
Level 3 Communications’ (NYSE: LVLT) first-quarter revenues declined sequentially and year-over-year to $1.58 billion due to the expected termination of various North America and UK government contracts.
During the first quarter, the company’s net loss was $0.36 per share, including $0.11 in foreign exchange losses in EMEA and Latin America.
“In the first quarter, we saw the effects of the near-term revenue pressures we cited last quarter, due to the typical reversal in seasonally strong fourth quarter revenue and some known contract disconnects in North America and UK Government,” said Sunit Patel, CFO of Level 3. Patel said that “our gross margin is now back above 60 percent for the first time since acquiring Global Crossing.”
Despite these initial revenue challenges, Level 3′s total Enterprise Core Network Services (CNS) revenue grew 2.2 percent year-over-year to $1.37 billion. Taking out the impact of UK government revenue, Enterprise CNS revenue grew 6.8 percent year-over year. Wholesale revenue, meanwhile, declined to $501 million, while wholesale voice and other revenue declined to $205 million.
On a regional basis, North America was the clear leader with $967 million in revenue, while EMEA and Latin America posted revenues of $223 and $182 million, respectively.
David Dixon of FBR wrote:
"While Level 3 continues to generate benefits from the Global Crossing merger, and we welcome incoming CEO Jeff Storey, our concerns about weak top-line trends and cost structure continue to be borne out. In the retail enterprise segment, a tough macro environment is coupled with a challenging pricing environment for connectivity services, which are largely commoditized. Furthermore, generationally challenged Ethernet equipment is an issue. Level 3 has avoided significant capex over the past two years by using Huawei engineers under contract to tune lasers on older fiber on a hop-by-hop basis to increase capacity and avoid network upgrades; however, excess capacity is unclear. In the wholesale segment, wireless backhaul demand is a potential bright spot, as demand for backhaul is increasing.
Cable companies are focused on offering lit fiber versus dark fiber to maintain owner economics. For Level 3, it is unclear to what extent the company would sell metro dark fiber circuits to wireless companies seeking fiber-based backhaul and feeder fiber from IXC hubs. While Level 3 gives up owner economics in this case, it may be the preferred approach, as wireless carriers are reluctant to use Level 3 to source lit fiber because of concerns regarding a lack of a capacity upgrade path —i.e., Level 3 can provide 100 Mbps today, but carriers need substantially higher capacity going forward. And our checks confirm that customer confidence is low regarding the company's ability to increase investment levels to meet growing capacity requirements (particularly in a virtualized network context), primarily due to balance sheet concerns.
■ CNS* revenues weaker than expected, but EBITDA beat expectations as margins rebound—a flip from results last quarter. CNS revenue of $1,372M in 4Q12, up 1.6% YOY, was below our $1,418M estimate and consensus of $1,390M. One of the primary growth drivers was Latin America (13% of CNS revenues). Adjusted EBITDA were $386M, above our $378M estimate and consensus of $378M. The 24.5% EBITDA margin was ahead of consensus and our estimate of 23.5%, the first margin above 24% since the merger closed in 4Q11.
* Editors Note: We don't know if Core Network Services (CNS) also includes Content Delivery Networks (CDNs), which Level 3 provides to other service providers. Their CDN is said to "support some of the largest video, software and web properties. The Level 3® Network is connected with direct, private connections to almost every major ISP and Telco, which allows traffic to flow directly to end users without traversing public peering points."
■ Reiteration of weak EBITDA guidance. For the second-largest ISP after Google, modest revenue growth, low-double-digit EBITDA guidance, and what we interpret as modestly positive FCF growth (i.e., positive FCF, excluding $56M
in interest rate swap liabilities) are weak. Capex spending remains moderate, tracking below expectations, and a 4% head-count reduction taken late in the fourth quarter may provide a boost to EBITDA by $40M but will likely challenge
top-line growth in FY13."

The Feb 2013 ITU-T SG 13 Plenary meeting report lists Question 13 as having primary responsibility for investigating Software Defined Networking and Network Virtualization.
Here is a cut and paste of the pertinent ITU-T SG13 Plenary report:
TD 26 (PLEN/13)
Software Defined Networking (SDN) and network virtualization are among promising technologies because they enable network operators to divide networks into partitions to make problem size smaller, and to control their networks in unified, programmable manner. This realizes multiple isolated and flexible networks in order to support a broad range of network architectures, services, and users that do not interfere with others. It is considered as one of the key technologies for FNs, and various SDOs have started to study these technologies in intensive manner, but overall framework that covers all telecom industry has not yet been defined. And there are other approaches to mitigate the diversity and complexity by e.g., introducing easily-manageable network architecture such as carefully-designed decentralization and autonomicity.
The Recommendations that specifies framework, service scenarios, requirements, and architecture of service-aware networking, in particular network virtualization and SDN technologies, fall under the responsibility of this question. As for SDN, the focus is on common part of SDN that is applicable to various networks, and its application to future networks.
Study items to be considered, but not limited to:
•Requirements for the architecture to manage and to operate exploding and diversifying services and supporting functions in particular SDN and network virtualization
•Analysis of gaps between SDN, service-aware networking and existing standards and/or technologies
•Approaches, architectures and mechanisms for highly-scalable and distributed SDN and service-aware networking easy to control, operate and manage
•Issues and solutions for migrating from current IP-based network to SDN and service aware networking.
Tasks include, but are not limited to:
•Produce new Recommendations on requirements, functional architecture and mechanisms of generic SDN, its application to future networks, and service aware networking.
•Produce Recommendations on general overview of service aware networking
•Y.3011, Y-series Recommendations
•All SDN and FN related Questions
•ITU-T Study Groups involved in SDN and FN studies
Standardization bodies, fora and consortia:
•ISO/IEC JTC1 SC 6
•ETSI ISG Network Functions Virtualization (NFV)
•Open Networking Foundation
And that's "all she wrote" about ITU-T standardization of SDN and Network Virtualization
Qualcomm Earnings report: competition in Asia for cheap smartphones-Ominous For Apple, BlackBerry, Nokia?Thu, 04/25/2013 - 13:50 — Jake Gibbs
Qualcomm Incorporated (Nasdaq: QCOM), a leading developer and innovator of advanced wireless technologies, products and services, today announced results for the second quarter of fiscal 2013 ended March 31, 2013.
"We delivered another strong quarter as the worldwide adoption of smartphones continues," said Dr. Paul E. Jacobs, chairman and CEO of Qualcomm. "Looking forward, we are seeing strong traction with our new Qualcomm Snapdragon 600 and 800 processors, and we continue to expect healthy growth in 3G and 3G/4G multimode devices around the world. We are pleased to be raising our calendar 2013 3G/4G device shipment estimates and our revenue and earnings guidance for fiscal 2013."
Second Quarter Results (GAAP)
- Revenues: 1 $6.12 billion, up 24 percent year-over-year (y-o-y) and 2 percent sequentially.
- Operating income: 1 $1.88 billion, up 24 percent y-o-y and down 10 percent sequentially.
- Net income: 2 $1.87 billion, down 16 percent y-o-y* and 2 percent sequentially.

- Return of capital to stockholders: $431 million, or $0.25 per share, of cash dividends paid.
Forbes: Qualcomm Cheap Phone Warning is Ominous
Qualcomm owns intellectual property related to code division multiple access (CDMA). This technology is behind many of today’s wireless networks. Qualcomm also provides chip sets for mobile devices. Since Qualcomm licenses the technology or provides the guts of a wide base of wireless devices and networks, there are serious implications for smartphone manufacturers in Qualcomm’s results.
martphone prices are falling much faster than expectations. Of further concern is the number of new entrants in the smartphone market. Somewhat shocking was a statement by Qualcomm that some of its customers are able to launch their devices in as little as 60 days from start to launch. These customers are using Qualcomm Reference Design (QRD).
As of January 2013, 170 QRD based devices have been commercialized by more than 40 manufacturers. The irony here is that based on the large number of emails I receive, investors tend to extrapolate from their experiences in the United States and Europe and do not realize that there are more than 40 manufacturers of smartphones. The 60-day time to launch is in stark contrast with the traditional time of nine months to a year.
This is real bad news for Apple. Growth is in emerging markets as the developed markets are mostly saturated. In emerging markets, disposable incomes are not high enough for the masses to afford existing Apple products. Apple has already ruled out a $99 iPhone. The indications are that Apple is hard at work on a low end phone. Nobody knows the price of the future low-end iPhone. Most of the informed speculation centers around a price in the range of $300 to $400 in contrast to the $613 average selling price of the present iPhone.
The strong inference from Qualcomm’s earnings report is that smartphone prices are falling so fast that the new low end Apple iPhone is not likely to be competitive.
BlackBerry has been touting its success in emerging markets with Z10, but Z10 is simply too expensive for these markets. BlackBerry’s CEO is on record saying that BlackBerry is working on a low end phone. However considering how fast smartphone prices are falling, even if BlackBerry is able to introduce a new device at 50% of the current price of Z10, it is not likely to become competitive.
Qualcomm’s earnings report validates Nokia’s strategy for the emerging markets. Its line of low-end phones called Asha is doing well in emerging markets, but Nokia is about to face stiff competition primarily from Chinese manufacturers. Most of the phones from the new entrants are based onGoogle GOOG -0.14% Android. Further, these new entrants are shying away from Windows Phone OS.
The bottom line is that a sea change is on the horizon which is good for Google and Qualcomm but bad for almost everyone else.

See Intel’s press release (http://newsroom.intel.com/community/intel_newsroom/blog/2013/04/17/intel-accelerates-the-data-center-and-telecom-network-transformation-with-new-reference-architectures) for more information.
“SDN and NFV are critical elements of Intel’s vision to transform the expensive, complex networks of today to a virtualised, programmable, standards-based architecture running commercial off-the-shelf hardware. The reference designs announced today enable a new phase in the evolution of the network and represent Intel’s commitment to driving an open environment that fosters business agility and smart economics,” Ms Schooner said in the press release.
Rose invited Allwyn Sequeira, VP/CTO of Security and Networking at VMware, on the stage to talk about their ongoing collaboration. Allwyn talked about the NSX platform, and emphasized decoupling networking from the underlying hardware to “abstract, pool, and automate” network resources like virtualized servers. NSX is based on overlays and network virtualization. It doesn't conform to the strict ONF definition of SDN, nor does it use the Open Flow protocol. Prodip Sen, Director of Network Architecture at Verizon talked about their collaboration with Intel on a cloud bursting trial with dynamic bandwidth allocation/re-allocation.
After the conference, Rose made the following comment via email to this author: "I completely agree that SDN and NFV are complimentary but different – that’s the Intel view as well. We created the 2013 ONS presentation with the assumption that the difference was understood by the audience."

A NV platform consists of an intelligent edge (virtual) switch, distributed controllers, and tunnels that decouple network services from the physical infrastructure (e.g. VMware’s NSX platform.) Bruce said that “network overlays solve more problems than they create, they will enable network service innovation at software speeds, and that NV is its own thing (i.e. it delivers its own value, apart from SDN)." The Microsoft and Ebay ONS presentations certainly supported his favorable view of NV over stictly defined SDN-Open Flow.
as well as some customers looking to reap some benefits from SDN. Second, there was the approach labelled "SDN-washing" by Guru Parulkar. This was represented by some of the traditional networking vendors. The basic idea is to retain the full-featured, largely proprietary systems, but to dress them up with some sort of API, be it OpenFlow or something proprietary. As Guru said, this doesn't really conform to the intent of SDN. Finally, there is the network
virtualization school, well represented in the session on Data Center applications. As was clear from my talk, I subscribe to this school of thought. (Microsoft's) Albert Greenberg's description of the Windows Azure architecture very much matches our vision of network virtualization, and JC Martin from eBay has already reaped the rewards of deploying network virtualization in his data center."
