Netopia Uses VLANs to Map Services in DSL Gateways

Netopia introduced a Virtual Gateway (VGx) technology designed for mapping Triple Play services in DSL networks to specific QoS priority levels. The VGx technology, which is implemented in Netopia's 3300 series broadband gateways, allows service providers to separately deliver and manage up to eight individual service channels. The technology maps multiple VLANs to one or more specific permanent virtual circuits (PVCs) for DSL, or to other wide area VLANs in the case of fiber networks. Traffic prioritization is based on 802.1p.

Amedia Adds VDSL Option for its FTTP/N Solution

Amedia Networks announced a VDSL-based copper interface for its AS5000 Aggregator Switch and PG1000 Premises Gateway. The option complements the Fiber-To-The-Premises (FTTP) access solution that the company announced last year by enabling a Fiber-To-The-Node (FTTN) capability for copper based networks. Service providers, including those that currently deploy DSL services, would be able to install DMT-coded VDSL line cards in the AS5000 in order to provide standards-based Ethernet access over copper twisted pairs.


Depending on the distance between the node and the premises, the VDSL-optioned QoStream products will be able to offer between 20 Mbps to 100 Mbps over copper wires, both into and out of premises. For service providers preferring "home run solutions," the AS5000 can reside in a Central Office in addition to residing at a remote node in the outside plant.

Security in Broadband Access
Architectures




Security in the local loop hasn't been an issue up to now. Local
operating companies have deployed dedicated cabling with multiple twisted
pairs to each subscriber and MSOs have installed high speed co-ax cabling
for TV services. It's common for home workers to set up IPSec tunnels to
protect corporate information assets. Access networks must be secure,
without inadvertent distribution of data to the wrong subscriber or
deliberate theft of service.

Cisco Releases IP/MPLS Interprovider Capabilities

Cisco Systems announced IP/MPLS interprovider capabilities that allow service providers to work with each other and combine the capabilities of their individual networks, as a way to offer new services to their business customers. Cisco said service providers that take full advantage of the new IP/MPLS interprovider solutions would be able to deliver increased resiliency, multicast-based services such as streaming video, and extended virtual-private-network (VPN) technologies to their enterprise business customers.

The new Cisco IP/MPLS enhanced interprovider capabilities include:

  • Inter-Autonomous System (Inter-AS) Multicast VPN -- this allows service providers to provide enterprise customers scalable Layer 3 multicast services on an IP network that shares resources, on one or more physical networks.


  • Inter-AS Traffic Engineering, which allows service providers to traffic engineer between networks and regions, previously not available. It involves the configuration of a single tunnel at the headend as opposed to switching tunnels across each area that must be crossed, enabling service providers to deliver more robust, resilient and scalable networks.


  • Interprovider MPLS VPN over IP, which allows traditional MPLS-based Layer 3 VPN services to be delivered on a native IP network, simplifying connectivity across a single or multiple transit IP networks. This functionality allows service providers more flexibility in building IP network architectures across domain boundaries, allowing additional revenue opportunities by building scalable Layer 3 VPN services, such as Web hosting, application hosting, interactive learning, electronic commerce and telephony service.


  • MPLS VPN Inter-AS/Carrier Supporting Carrier (CSC) Load Balancing, which allows service providers to load balance across two or more links between boundary routers. Previously, service providers could fully utilize one link between peering routers. The increase in links enables additional flexibility, better redundancy and network scalability for the delivery of improved SLAs.


The Cisco Interprovider capabilities are shipping now in Cisco IOS Software releases 12.0(29)S and 12.0(30)S.

Verizon Speaks Out Against Qwest+MCI Deal

Verizon Communications issued a public statement arguing that the possible combination of Qwest and MCI is not in the public interest.


Tom Tauke, Executive Vice President of Verizon, said a Qwest acquisition of MCI "could result in less investment in MCI's networks and Internet backbone, and harm national security-related customers and the long-term interests of large businesses, government agencies, consumers and shareholders." Tauke noted that Verizon has estimated it will invest approximately $3 billion, primarily in MCI's Internet backbone, network and systems. Tauke argues that cash-strapped Qwest could decide to channel Internet traffic onto its own network and potentially remove a backbone competitor.

Caspian and ETRI to Develop Flow State Routing for Korea's BcN

Caspian Networks has been selected by South Korea's Electronics and Telecommunications Research Institute (ETRI) to co-develop advanced IP flow state solutions for the nation's Broadband convergence Network (BcN). The project will combine Caspian's flow state technology with ETRI's technical expertise in network control and simplified multi-protocol labeling switching (sMPLS).


The BcN project is targeting a goal to build an integrated network in South Korea with bandwidth of 50 ~ 100 Mbps per end user that can offer seamless multimedia services to 20 million Korean subscribers using wired and wireless communications among heterogeneous networks. South Korea already has the highest broadband penetration rate in the world and high-speed residential connections offering tens of megabits of performance have been on the market for some time. The BcN initiative aims to drive connectivity to the next level, offering seamlessly connectivity between services. Network providers benefit with deterministic, guaranteed IP Quality of Service (QoS) offerings, mobility, and security for new and demanding multimedia applications as set forth by the BcN project. Users benefit with cutting edge integrated services, like IP video and music, online entertainment, real-time health and welfare response, Voice over IP, and more, regardless of device or location.





Caspian Networks, which is based in San Jose, California, has been developing flow-based routing since its founding in 2002 by Dr. Larry Roberts. In flow-based networking, packets are routed as whole flows, i.e. streams of related packets, rather than as individual packets as in current IP/MPLS networks. Caspian's existing "Apeiro" platform examines each packet entering the router, identifies flows, and then stores to memory the flow's relevant routing information as well as its QoS, loss, delay and jitter characteristics. Flows are identified by the combination of source address, destination address, source port, destination port, and protocol. Subsequent packets in the flow are switched based on the "flow state" data already in memory. By tracking potentially tens of millions of microflows per 10 Gbps interface per second in hardware, Caspian said its Apeiro platform provides deterministic QoS for premium IP traffic that is equivalent to ATM. The ASIC-driven platform is capable of handling flow set-ups significantly faster than the circuit set-up rates typical of ATM and MPLS.


Caspian will establish an R&D center in Korea to support the co- development efforts with ETRI and to serve as a technical support hub for the Asia Pacific region. Initially, Caspian expects to hire about 15 engineers.

PCCW and China Netcom Target Broadband TV Opportunity

China Netcom and PCCW, the incumbent carrier in Hong Kong, provided an investor update on their partnership deal announced last month. The companies are looking to capitalize on telecom growth in China, especially in broadband TV services. China Netcom currently has 110 million fixed line customers and 8 million broadband customers, the majority of which are in the ten northern Chinese provinces where it is the incumbent operator. China Netcom's strategy is to defend its territory in the north, while looking for new expansion in the south.


Since September 2003, PCCW, the incumbent operator in Hong Kong, has been offering Broadband TV. The service currently has over 400,000 subscribers. Customers can choose their preferred programs from more than 60 channels using an "a la carte" pricing system, while being able to enjoy 12 channels provided free of charge.


Together, PCCW and China Netcom see a huge opportunity for broadband TV in China, given the potential market of over 300 million TV households in the country. Based on third party research and forecasts, CNC and PCCW estimate China's broadband TV market could reach RMB 10 billion by 2008.


China Netcom expects its broadband subscriber base to keep growing at a CAGR of 40% , reaching 40 million subscribers by 2008. The company believes its current 8 million broadband subscribers will be early adopters of BBTV. Its first BBTV deployments will begin this year. Initial cities with high GDP per capita and high broadband penetration will be selected for the phase 1 pilot deployment.


If the BBTV service attracts a penetration rate of 15 to 20% by 2008, BBTV revenue might reach RMB 3.0 to 3.5 billion by 2008. Eventually, China Netcom and PCCW hope to target all households in China through partnerships with other carriers.


PCCW and China Netcom said they are also looking at other ways to capitalize on business opportunities, including 2G/3G services, the hot real estate market in China, cross-border communications and submarine cables.
