OFS Debuts Single-Mode Fiber for 100G with 12,000km Reach


OFS introduced a new single-mode fiber designed for 100 Gbps coherent transport in submarine systems for distances up to 12,000 km.

The new TeraWave ULA Ocean Fiber boasts the industry’s largest effective area, excellent cabling performance, and significantly reduced attenuation for reliable coherent transmission at 100 Gbps over trans-oceanic distances. OFS said its fiber’s very large effective area (153 ┬Ám2) reduces nonlinearities, enabling the launch of higher signal power into the span, and improves signal loss (0.176 dB/km at 1550 nm). When used in shorter length applications, the fiber can provide even better nonlinearity performance for increased spectral efficiency.

OFS said the new fiber is optimized for ultra long haul networks that use advanced modulation formats and coherent detection, such as transoceanic networks where extreme distances between shore end terminals limit the per-channel launch power in DWDM transmission.

NASA Launches Lowest Cost PhoneSats


NASA has successfully launched a trio of "PhoneSats" to determine whether a consumer-grade smartphone can be used as the main flight avionics of a capable, yet very inexpensive, satellite.

NASA's PhoneSats are currently in orbit and successfully transmitting information about their health to multiple ground stations on Earth.  The satellites, which are expected to remain in orbit for as long as two weeks, are being monitored by a team at the Ames Research Center in Moffett Field, California.


NASA said the three PhoneSat satellites are emitting packets over the amateur radio band at 437.425 MHz using AFSK (1200 bps) modulation, AX.25 packet coding and with vertical linear polarization.

"Smartphones offer a wealth of potential capabilities for flying small, low-cost, powerful satellites for atmospheric or Earth science, communications, or other space-born applications. They also may open space to a whole new generation of commercial, academic and citizen-space users," said Michael Gazarik, NASA's associate administrator for space technology in Washington.

Reporter Notes from ONS 2013: NTT Com, Internet 2, Google

By James E. Carroll, Editor
NTT Communications was among the first Service Providers to see the potential of OpenFlow and SDN for transforming its operations, said Yukio Ito, Senior VP Service Infrastructure, NTT Communications.  Some notes from his keynote at the Open Networking Summit 2013 in Santa Clara, California:

  • NTT Com's reasons for pursuing SDN include shorter time to market, service differentiation, and reduced CAPEX/OPEX.
  • NTT Communications has a Global Cloud Vision encompassing many of its enterprise services and all self-managed under an integrated cloud portal.
  • The company launched its SDN-enabled Enterprise Service in 2012, including the self-provisioning portal website.
  • OpenFlow is being used for inter-data center back-ups between NTT Communications' Global Data Centers.  The service allows bandwidth can be boosted on-demand using the OpenFlow controller.
  • The results of using OpenFlow/SDN for the Enterprise Cloud service have been good, including better service automation, a topology-free design, an the overcoming the 4K VLAN limitation that the network would otherwise face.  There have been some issues.  The OpenFlow v1.0 specification did not meet requirements for redundancy, current silicon has meant a "flow table shortage", and the network has generally been less programmable than NTT Communications expects.  The company is working to overcome these issues.
  • NTT Com is working on its SDN architecture that will provide a common framework for northbound and southbound interfaces.  The company will use vendors and/or open source if they meet its criteria.
  • NTT Com is very interested in extending SDN to the optical transport layer. The ONF's Optical Transport WG is expected to accelerate this discussion.
  • One additional challenge is that the interconnection between a data center network and an MPLS-VPN is not currently automated.  The company is developing a "Big Boss" SDN controller to address this challenge.

INTERNET2

The experimentation with Software Defined Networking underway in Internet2 in many ways parallels the birth of the commercial Internet, said Dave Lambert, President and CEO of Internet2.  Many U.S. companies, in fact, have their roots in academia, such as Cisco (Stanford), Sun (Berkeley and Stanford), Google (Stanford), Arbor ( U.of Michigan), Akamai (MIT), etc.

Some notes from his presentation:

  • It's time for a change. Most of the network paradigm was created 35 to 40 years ago, when Ethernet and IP emerged despite strong technical objections.
  • Will we fight re-centralization of an open control plane and hybridization to a potentially post-IP, SDN-based packet environment? This is like the packet-circuit debate with IBM's SNA group back in the day.
  • Getting bandwidth limitations out of the way for the academic community is a key objective.
  • Bandwidth and openness are imagination enablers.  An open networking stack is risky but is among the most exciting things.
  • Data intensive science in genomics and physics really do demand flexibility to handle massive data flows.
  • 29 major universities are committed to the Innovation Platform Program.  This entails (1) 100 GigE connectivity to their campus and across their campus (2) support and access Intenet2's Layer 2 OpenFlow-based service (3) Invest in developing applications that run across this network.
  • The U.S. academic is admittedly on the cutting edge. 

SDN @ GOOGLE

Google's software defined WAN, which is the basis its internal network between data centers, is real, it works, and has met the company's expectations in terms of scalability and reliability, said Amin Vahdat, Distinguished Engineer at Google.  Some notes from his presentation:

  • It's been a year since Google announced that its internal backbone had been migrated to SDN.
  • Growth in bandwidth continues unabated.   Google's internal backbone actually carries more traffic than its public-facing network.
  • Planning, building and provisioning bandwidth at Google scale had been a major headache, hence the interest in SDN. Over-provisioning costs were also a major driver to adopt SDN.  Slow convergence time in the event on an outage was another factor.
  • Google wanted to go with  logically centralized network control instead of the decentralized paradigm of the Internet.  This centralized approach leads to a network that is more deterministic, more efficient and more fault tolerant, according to Vahdat.
  • B4 is the name of Google's software defined WAN.  Vahdat describes it as a warehouse-scale-computer (WSC) network.  It links data centers around the world  (a map shows 12 nodes across Asia, North America and Europe) . So far this network is successful, so the next step may be to run some Internet user-facing traffic across this same backbone.
  • The B4 network runs OpenFlow. Google built its own network hardware using merchant silicon. The are 100s of ports of non-blocking 10GE.
  • Google uses Quagga for BGP and IS-IS.  A hybrid SDN architecture is used to bridge sites that are fully under SDN control and legacy sites. This means that SDN can be deployed incrementally.  You don't have it deploy it everyone on Day 1.
  • Traffic engineering is the first application on the SDN WAN. This was implemented about a year ago.  It takes into account current network demand and application priority.
  • Google has been adding capabilities pretty quickly through frequent software releases.

Symantec Tracks Growing Phishing and Watering Hole Attacks


Targeted cyber attacks, such as spear phishing, rose 42% in 2012 compared to a year earlier, according to Symantec's Internet Security Threat Report, Volume 18 (ISTR), released last week.

Over the past year, Symantec noted an increase in cyberespionage attacks targeted at the manufacturing sector as well as small businesses, which now constitute 31 percent of these attacks. This could be due to more sophisticated defenses in place at larger enterprises, or simply that the criminals have extended their reach to more organization.

Two significant attack vectors, according to the report, remain unpatched but legitimate websites (nearly 53% of legitimate websites were found to have unpatched vulnerabilities that hackers could potentially exploit to place malware) and mobile malware.

"This year’s ISTR shows that cybercriminals aren’t slowing down, and they continue to devise new ways to steal information from organizations of all sizes," said Stephen Trilling, chief technology officer, Symantec. "The sophistication of attacks coupled with today’s IT complexities, such as virtualization, mobility and cloud, require organizations to remain proactive and use ‘defense in depth’ security measures to stay ahead of attacks."

Some highlights of the report:

  • Watering hole attacks, where a legitimate website is poisoned and the hackers then wait for a victim to arrive, emerged as a rising threat in 2012. A large number of victims can be compromised in a short period of time.
  • Symantec estimates that 61% of websites serving malware are in fact legitimate website and unaware they have been compromised.
  • Global spam rates declined slightly in 2012.  Spam represented about 69% of all email sent in October 2012 compared to 79% in January 2011.
  • Symantec estimates that 1 in 414 emails is a phishing attack.
  • Symantec estimates that 1 in 283 emails is a malware attack.
  • Symantec found that Apple’s iOS had the most documented vulnerabilities in 2012, but that there was only one threat created for the platform. On the other hand, the Android OS only had 13 vulnerabilities reported, but led all mobile operating systems in the amount of malware written for the platform.

TE SubCom Carries 200G and 400G Channels Across TransPacific Span


TE SubCom has demonstrated transpacific transmission using both 200 Gbps and 400 Gbps data channels.  The test demonstrated a total capacity on a single fiber pair of 21 Tbps transmitted over more than 10,000km at a spectral efficiency of 6b/s/Hz.

TE SubCom said its achievement was enabled by careful engineering of the transmitted signals, in order to achieve both long-distance performance and high spectral utilization.

“Transpacific length transmission at 6b/s/Hz spectral efficiency is a significant milestone for undersea communications,” said Seymour Shapiro, CTO, TE SubCom.  “More impressive is that this was achieved using both 200 Gbps and 400 Gbps channels and large total capacity. Such 400Gb/s laboratory experiments typically require multiple coherent receivers, whereas our recent demonstration used a single high-bandwidth receiver.”

Intel Unveils Open Hardware Platforms for SDN and NFV

Intel introduced three platforms for software defined networking (SDN) and network function virtualization (NFV).

The product launch includes:

The Intel Open Network Platform Switch Reference Design, previously codenamed "Seacliff Trail," is based on scalable Intel processors, Intel Ethernet Switch 6700 series and the Intel Communications Chipset 89xx series.  It will include Wind River Open Network Software (ONS), an open and fully customizable network switching software stack using Wind River Linux. Wind River ONS allows for key networking capabilities such as advanced tunneling as well as modular, open control plane and management interface supporting SDN standards such as OpenFlow and Open vSwitch. Common, open programming interfaces allow for automated network management, and coordination between the server switching elements and network switches enabling more cost-effective, secure, efficient and extensible services.
 
The Intel Data Plane Development Kit Accelerated Open vSwitch  -- a project aimed at improving small packet throughput and workload performance that can be achieved on the Open vSwitch.  Intel is specifically re-creating the kernel forwarding module (data plane) to take advantage of the Intel DPDK library. The Intel DPDK Accelerated Open vSwitch is planned to initially be released with the Intel® ONP Server Reference Design in the third quarter of this year.
 
The Intel Open Network Platform Server Reference Design, previously codenamed "Sunrise Trail," is based on the Intel Xeon processor, Intel 82599 Ethernet Controller and Intel Communications Chipset 89xx series. The ONP Server Reference Design enables virtual appliance workloads on standard Intel architecture servers using SDN and NFV open standards for datacenter and telecom. Wind River Open Network Software includes an Intel DPDK Accelerated Open vSwitch, fast packet acceleration and deep packet inspection capabilities, as well as support for open SDN standards such as OpenFlow, Open vSwitch and OpenStack. The project is in development now: the first alpha series is slated to be available in the second half of this year.

"SDN and NFV are critical elements of Intel's vision to transform the expensive, complex networks of today to a virtualized, programmable, standards-based architecture running commercial off-the-shelf hardware," said Rose Schooler, vice president of Intel Architecture Group and general manager of Intel's Communications and Storage Infrastructure Group. "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."

In a keynote address at the Open Networking Summit conference in Silicon Valley, Schooler cited a number of companies planning to build products based on these platforms, including Big Switch, HP, NEC, NTT Data, Quanta, Super Micro, VMware and Vyatta (a Brocade company). 

Some other points:

  • Intel is working with NEC and Telefonica to develop a network virtualization of the Evolved Packet Core.  The design puts MME and S/P GW functions on an ATCA Chassis.
  • VMware is working with Intel on a network virtualization solution for software defined data centers (SDDC).
  • Intel is using SDN concepts in its own data centers.
  • Intel is working with HP and Verizon to test a cross-country, cloud bursting between distant data centers.  The trial involves an Intel private cloud in Portland, OR, and HP Lab in Plano, TX, and a Verizon Public Cloud lab in Waltham, MA.
