Packet Design Provides Visibility into Layer 3 MPLS-VPNs

Packet Design introduced a network management product that provider visibility into MPLS-VPN customer traffic not only at the network edge but across the core.


VPN Traffic Explorer lets service providers determine the exact path each customer's traffic travels, know which customers are the heaviest bandwidth users, and analyze customer traffic by class of service (CoS) not just on a few links but everywhere in the network.
Armed with this new level of VPN-centric management knowledge, providers can resolve customer problems faster, do far more effective capacity planning, and pinpoint trends to better tailor existing services and sell new ones.


The new product combines Packet Design's foundation technology, route analytics -- which provides visibility into real-time, network-wide routing paths -- with the ability to map VPN customer traffic flows directly onto those paths. The product supports the newest versions of router-based flow data, including Cisco's NetFlow version 9, which recognize not only IP but also MPLS, the mechanism used by service providers to forward customers' VPN traffic across their network cores using private "tunnels."


Packet Design said previous solutions aimed at Layer 3 MPLS-VPN service management gather traffic data from the provider's edge routers, showing how much traffic each customer is sending. But they provide no insight inside the MPLS core, which typically exists one "hop" in from the edge and where problems can impact the quality of service for many customers.http://www.packetdesign.com

IEEE P802.3ba Task Force Sets Sights on 40GbE, 100GbE

The IEEE New Standards Committee (NesCom) has approved the Higher Speed Study Group's project authorization request (PAR), and the resulting project will now be known as the IEEE P802.3ba task force.


In July 2007, the Higher Speed Study Group (HSSG) agreed upon a single project encompassing a 40 Gigabit Ethernet (40GbE) rate for server and storage applications and a 100 Gigabit Ethernet (100GbE) rate for network aggregation. In November 2007, the IEEE 802.3 working group authorized the HSSG to become the IEEE P802.3ba task force to begin work on the 40GbE and 100GbE draft standard. The Task Force will now focus on defining the standard for 40GbE and 100GbE, and expects to complete standard ratification in 2010.


"This is a key milestone for the 40GbE and 100GbE project, and the result of collaboration between many individuals who have helped the IEEE P802.3ba task force gain momentum," said John D'Ambrosia, newly appointed chair of IEEE P802.3ba task force. "During last week's interim session, we began to hear initial technical presentations as part of the effort to work towards a first draft standard proposal expected to be completed by Fall 2008."


The Ethernet Alliance noted that the IEEE P802.3av (10Gb/s PHY for EPON) task force has finalized its task force review of draft D1.0 and is preparing the next revision of the draft standard.http://www.ethernetalliance.org

Cisco Unveils Massive Nexus 7000 Switch for Virtualized Data Centers

Cisco unveiled its the next generation, flagship data center-class switching platform for combining Ethernet, IP, and storage capabilities across one unified network fabric.

The Cisco Nexus 7000 Series, which sets forth the company's Data Center 3.0 vision, represents the culmination of over $1 billion in R&D, according to the company. The platform is designed for next generation data center infrastructure deployments of virtualized servers, storage, networks and applications. Using a unified fabric would eliminate the need for parallel storage and computational networks, reducing the number of server interfaces and significantly reducing the cabling and switching infrastructure required in the data center. At the heart of the network is a lossless unified switching fabric capable of simultaneously forwarding storage, Ethernet, and IP traffic.


Cisco's Nexus 7000 is a scalable modular platform that delivers up to 15 terabits per second (Tbps_ of switching capacity in a single chassis, supporting up to 512 10 Gbps Ethernet and future delivery of 40- and 100-Gbps Ethernet. Its unified fabric architecture combines Ethernet and storage capabilities into a single platform, designed to provide all servers with access to all network and storage resources. Key components of the unified fabric architecture include unified I/O interfaces and Fibre Channel over Ethernet support to be delivered in the future.


The design of the Nexus 7000 is also optimized for improved airflow and offers integrated cable management. The data plane is fully distributed and, when coupled with the Cisco NX-OS operating system, is designed to enable zero service-disruption upgrades on production systems. NX-OS combines the best of Cisco's SAN-OS, Layer 2 switching, Layer 3 routing protocols, and advanced virtualization capabilities. These virtualization capabilities allow the system to be partitioned into multiple logical devices, each with its own processes and command-line interface running independent of one another. This system may be used by hosting providers and complex enterprise administrative models, to be shared by multiple administrators concurrently, each with its own switching environment.


The Nexus 7000 Series starts at $75,000. Availability is expected in Q2 2008.

Verizon Tops 1 Million FiOS TV Customers, Adds 2 Million Wireless Customers

Citing gains in strategic growth areas such as wireless, broadband, data, video and global IP, Verizon Communications reported $23.8 billion in Q4 2007 revenues, up 5.5 percent; up 5.6 percent on an adjusted basis (non-GAAP) and earnings of 37 cents in fully diluted earnings per share (EPS). This compares with fourth-quarter 2006 earnings of 48 cents per share before income from discontinued operations that have since been divested.


"In the fourth quarter, the momentum of revenue growth and margin expansion continued to drive double-digit earnings growth, and we once again reported strong growth in sales of all our strategic products," said Verizon Chairman and CEO Ivan Seidenberg.


Some highlights for the quarter.


Wireless


  • 2.0 million total net customer additions, 1.9 million net retail customer additions; 65.7 million total customers, 63.7 million retail (non-wholesale) customers; 6.9 million retail net adds in 2007, the most of any carrier.
