Adtech Delivers OC-48c Packet Over Sonet Test Solution for IP.Business Editors WASHINGTON--(BUSINESS WIRE)--Jan. 25, 2000 Adtech, Inc., a SPIRENT Communications company Communications Company is a communications unit of the United States Marine Corps. They are part of Combat Logistics Regiment 37 , 3rd Marine Logistics Group (3MLG) and III Marine Expeditionary Force (III MEF). The unit is based out of the Marine Corps Base Camp Smedley D. , announces today that it is delivering a new 2.488 Gbps Packet over Sonet A metropolitan area network (MAN) or wide area network (WAN) transport technology that carries IP packets directly over SONET transmission without any data link facility such as ATM in between. (POS (1) See point of sale and packet over SONET. (2) "Parent over shoulder." See digispeak. POS - point of sale ) Generator/Analyzer module for its AX/4000 Broadband Test System. With this module, network switching equipment designers and service providers can now perform operational testing and continuous on-line monitoring of high-performance IP-based networks and equipment at OC-48c speeds, the fastest line rate in general use today. Adtech's 2.488 Gbps POS Generator/Analyzer module generates up to 4,095 test streams with each stream containing literally billions of traffic flows. Eight fully independent traffic sources allow users to generate constant bit rate and variable bit rate traffic on the same physical link for testing a variety of class of service technologies including 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. and DiffServ. Users can also add sophisticated real-time distribution models to generate traffic with variable IP packet lengths and interarrival times. Avici Systems Inc., a developer of next generation Internet See Internet2. backbone platforms will use the module with its existing AX/4000 Test System to perform Quality of Service (QoS) testing of its 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)). &uot;Avici's TSR performs at full OC-48 line rate with IP QoS,&uot; said Scott Poretsky, manager, System Test, Avici Systems. &uot;My challenge was finding test equipment that could keep up. The Adtech AX/4000 was the clear choice to verify QoS operation of the Avici TSR when forwarding IP, MPLS, and ATM.&uot; The module also identifies and analyzes up to 4,095 incoming substreams simultaneously based on virtually any type of IP traffic classification. In addition to providing a complete set of QoS measurements for each substream at full-rate, the analyzer can perform full-rate capture for IP protocol decoding. OC-48c IP QoS testing can be performed in conjunction with other Adtech IP QoS test modules, which cover a variety of media types and speeds from SONET OC-3 through SONET OC-12 including POS and IP/ATM. &uot;We developed our OC-48c POS Test Solution to help leading-edge switch developers like Avici build faster and better IP-based carrier network equipment,&uot; said Alan Sguigna, Adtech's vice-president of marketing. &uot;The TSR's scaleable and flexible architecture for next generation networks is ideally suited for the AX/4000.&uot; Adtech's AX/4000 Broadband Test System was recently named &uot;Best of the Best&uot; by InternetWeek magazine.
