Cisco Announces New Packet-over-SONET/SDH Solutions for Service Provider and Enterprise WAN Networks; New Port Adapter Enables High Performance, Flexibility and Scalability.SAN JOSE, Calif.--(BUSINESS WIRE)--Aug. 5, 1998--Cisco Systems Inc. (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :CSCO CSCO Cisco Systems Incorporated (stock symbol) CSCO Chief Supply Chain Officer ) 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 (1) See point of sale and packet over SONET. (2) "Parent over shoulder." See digispeak. POS - point of sale ) provides the same level of high switching performance as the existing Packet-over-SONET/SDH Interface Processor (POSIP POSIP Porsche Side Impact Protection POSIP Point Of Sale over Internet Protocol POSIP Packet-Over-SONET Interface Processor POSIP Portable Shipboard Instrumentation Package POSIP Pos Interface Processor ) 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 Internet service provider (ISP) Company that provides Internet connections and services to individuals and organizations. For a monthly fee, ISPs provide computer users with a connection to their site (see data transmission), as well as a log-in name and password. (ISP (1) See in-system programmable. (2) (Internet Service Provider) An organization that provides access to the Internet. Connection to the user is provided via dial-up, ISDN, cable, DSL and T1/T3 lines. ) 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 Cisco's trade name for its high-end layer 3 switch routers. (GSR See Gigabit Switch Router. ). 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 Weighted random early detection (WRED) is a queue management algorithm with congestion avoidance capabilities. It is an extension to Random early detection (RED) where different queues may have different buffer occupation thresholds before random dropping starts, as well as (WRED WRED Weighted Random Early Detection WRED Weighted Random Early Discard WRED Women and Rural Economic Development ) 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 (Local Area Network) A communications network that serves users within a confined geographical area. The "clients" are the user's workstations typically running Windows, although Mac and Linux clients are also used. 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.
