Spirent Communications Ships Industry's First OC-192c/STM-64c Line Rate Test Solution; Avici Systems first to measure OC-192c performance.Business Editors/High Tech Writers WASHINGTON--(BUSINESS WIRE)--Jan. 29, 2001 Spirent Communications, the world leader in performance analysis solutions, today announced that its Adtech AX/4000 10 Gbps generator/analyzer has been used to help deliver Avici Systems' (www.avici.com) OC-192C product for the Terabit-Switch/Router (TSR (Terminate and Stay Resident) Refers to a program that remains in memory when the user exits it in order that it be immediately available at the press of a hotkey. (R)), the leading scalable core router A router that resides within the middle or backbone of the network rather than at its periphery. The routers that make up the backbone of the Internet are core routers. See edge router and WAN router. . "Spirent Communications began shipping its OC-192c generator/analyzer in 3Q2000," said Alan Sguigna, vice president of marketing for Spirent Communications, Adtech Division. "Our first-to-market OC-192c test solution is speeding the deployment of core routing devices to ensure optimal performance in next generation networks." In addition to measuring OC-192c performance of the Avici TSR, Spirent's Adtech AX/4000 has also successfully verified the TSR's unique composite link restoration capability and features such as IP Quality of Service (QoS) using IP precedence to allow service providers to deliver new revenue generating services. Avici's Composite Link feature, enables customers to dynamically aggregate up to 16 OC-192c interfaces to create 160 Gbps connections between routers. This feature simplifies IP routing table A database in a router that contains the current network topology. See routing protocol. entries and enables upgrades from OC-48c to OC-192c while the link is in service, eliminating the network disruption and minimizing the network engineering usually associated with connection upgrades. This underscores Avici's commitment to non-disruptive scalability for leading service providers and their backbone infrastructures. "Adtech's OC-192c testing capabilities enabled us to verify the performance of our OC-192c module to ensure that it met the requirements of our TSR customers," said Scott Poretsky, manager, Development Test for Avici Systems. "As the first and most evolved OC-192c test solution, the Adtech AX/4000 was the clear choice to verify performance and QoS operations of the Avici TSR when forwarding IP and MPLS (1) (MultiProtocol Lambda Switching) The earlier name for GMPLS. See GMPLS. (2) (MultiProtocol Label Switching) A standard from the IETF for including routing information in the packets of an IP network. traffic." Avici uses the Adtech AX/4000 10 Gbps generator/analyzer to generate sophisticated real-time traffic distribution models with a wide variety of traffic flow and packet length distributions. Traffic can be grouped into user-defined traffic classes for testing Class of Service (CoS) technologies such as IP DiffServ to provide customers an open industry standard for high-speed IP transport over optical networks. Avici analyzes its OC-192c packet forwarding Forwarding is the relaying of packets from one network segment to another by nodes in a computer network. The simplest forwarding model - unicasting - involves a packet being relayed from link to link along a chain leading from the packet's source to its destination. capabilities using Spirent's sophisticated filtering and auto-identification of incoming packets. Spirent's Adtech AX/4000 filter automatically separates incoming traffic of up to 1,020 substreams based on user-configured settings such as IP source and destination addresses, TCP/UDP TCP/UDP Transmission Control Protocol/User Datagram Protocol ports, MPLS labels and Adtech mAX Tag test stream identifiers. Once filtered, QoS statistics for throughput, loss, latency, and sequence are available simultaneously for all 1,020 substreams in real-time for immediate feedback.
