Cisco Announces New Packet-over-SONET/SDH Solutions for Service Provider and Enterprise WAN Networks; New Port Adapter Enables High Performance, Flexibility and Scalability [[All, Last week I stated that the emerging Packet over SONET technologies that the bigger vendors were coming out with would require a change-out in the field, because most of the existing routers were not compliant. I guess I was wrong, because someone else at CSCO had the same idea. CSCO's POS "port adapter" is released, and cited as their solution to that problem, for some of its higher-end devices. I don't know quite exactly what they mean by an 'adapter.' Does anyone know what kind of bulk this adds or subtracts to/from the configuration? Also, note the parameter they cite in terms of "Committed Access Rate (CAR)." How does this depart from Committed Information Rate (CIR)? My guess is that it is a form of tacit admission that what goes in, doesn't always necessarily come out, in the world of TCP/IP. But that's ok, as long as there is sufficient head room in the cloud, and the WAN becomes nothing more than a very large collision domain. That's how Ethernet has conquered the workspaces and the backbone in high rises, isn't it? It's like the attitude that suggests that if you miss your bus on Broadway, not to worry, because there's always another one right behind it. Comments, clarifications and all forms of educational assistance are absolutely welcome. Regards, Frank C.]] --------------- August 6, 1998 SAN JOSE, Calif.--(BUSINESS WIRE) via NewsEdge Corporation -- Cisco Systems Inc. (NASDAQ:CSCO) today announced a new Packet-over-Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) port adapter for the Cisco 7500 and 7200 series routers. The new port adapter will enable high performance, flexibility and scalability in service provider and large enterprise WAN applications. "The explosive growth of the Internet coupled with the continued expansion of large enterprise WANs has driven the convergence of technologies," said Richard Palmer, director of marketing for Cisco's Routed WAN Business Unit. "The new Packet-over-SONET/SDH port adapter merges IP and SONET/SDH transport networking for both the Cisco 7500 and 7200 series routers." The Packet-over-SONET/SDH port adapter (POS) provides the same level of high switching performance as the existing Packet-over-SONET/SDH Interface Processor (POSIP) in a single-wide port adapter design. This allows flexible, high-performance networks to be designed with greater port density. With the Virtual Interface Processor 2-50 (VIP2-50) in the Cisco 7500, the POS port adapter substantially increases performance for applications requiring greater connectivity options. In addition, different port adapter technologies such as serial, multichannel, Ethernet and Fast Ethernet, can be combined with the POS port adapter in the same VIP to provide greater network design flexibility and increased port density. In addition, the POS port adapter extends the benefits of Packet-over-SONET/SDH connectivity to the Cisco 7200 series router. Providing tremendous network flexibility, the POS port adapter can be deployed on the Cisco 7200 in SONET/SDH networks that require a large number of distributed multiservice edge routers. Designed for a wide range of applications, the new POS port adapter is ideal for Internet service provider (ISP) backbones and network connectivity for large enterprise WANs. The POS port adapter is specifically suited for building high-speed, fault-tolerant IP networks that use the Cisco 12000 Gigabit Switch Router (GSR). In addition, the POS port adapter supports Cisco's IP class-of-service (CoS) capabilities such as Committed Access Rate (CAR), Random Early Detection (RED) and Weighted Random Early Detection (WRED) so service providers can offer differentiated services while providing advanced SONET features such as Automatic Protection Switching (APS) and payload scrambling. "Mapping IP packets directly onto the SONET/SDH infrastructure will provide greater performance and bandwidth utilization than other Layer 2 transport methods," said Edward Kern, vice president of IP Network Services at DIGEX/Intermedia Communications. "The ability to deploy this technology close to customers in the Cisco 7500 and 7200 series routers and into the backbone Cisco 12000s without having to go through an intermediate LAN technology means enhanced performance, stability and greater bandwidth to the network edge for our business Internet customers." Availability The POS port adapter is a single-port, single-wide OC3c/STM-1 port adapter for the Cisco 7500 series router with the VIP2-50 and the Cisco 7200 series router with the NPE-150 and NPE-200. The POS port adapter is available in three physical interfaces: OC-3c/STM1 Multimode, OC-3c/STM1 Single-Mode Intermediate Reach (SM-IR) or OC-3c/STM1 Single-Mode Long Reach (SM-LR). All interfaces for the Cisco 7500 and 7200 series routers are available in August 1998. About Cisco Systems Cisco Systems Inc. (NASDAQ:CSCO) is the worldwide leader in networking for the Internet.
