Harris & Jeffries Announces Soft-ATM PNNI Routing Subsystem.DEDHAM, Mass.--(BUSINESS WIRE)--Nov. 11, 1996-- Harris & Jeffries, Inc. (H&J), a leading developer of ATM source code, announced today the release of Soft-ATM PNNI (Private Network-to-Network Interface) A routing protocol used between ATM switches in an ATM network. It lets the switches inform each other about network topology so they can make appropriate forwarding decisions. (Private Network-to-Network Interface) Routing Subsystem. The Soft-ATM family of products provides manufacturers with a wide variety of networking source code components that allow them to develop very advanced ATM network products cost effectively, while improving overall product performance and dramatically improving product time-to-market. The new Soft-ATM PNNI Routing Subsystem allows each switch in a network to share topology information, which is then used to dynamically determine the best route through an ATM network, using source routing, based on parameters such as Quality of Service (QoS). Currently ATM switches use static configurations to route signalling information between switches via the Interim Interswitch Signalling Protocol (IISP IISP Information Infrastructure Standards Panel (ANSI) IISP Interim Interswitch Signaling Protocol IISP Institute of Information Security Professionals IISP International Institute for Software Process ). The PNNI Routing Subsystem supports the ATM Forum's path selection algorithm which can be preempted in favor of a customer supplied path selection algorithm. This powerful software also supports crankback and anycast group addressing. The new PNNI routing subsystem is fully compliant with The ATM Forum's specifications for PNNI routing and the PNNI errata. It supports single peer groups and participation in multi-peer group networks as defined by The ATM Forum. The company said it plans to add support for multi-peer groups, peer group leader (PGL Persistent generalized lymphadenopathy (PGL) A condition in which HIV continues to produce chronic painless swellings in the lymph nodes during the latency period. Mentioned in: AIDS ), logical group node (LGN) border node, and hierarchical routing in the first quarter of 1997. The highly portable source code package is hardware and operating system independent, and can be used in single or multi-processor systems. The unique flexible architecture allows multi-processor systems to distribute different PNNI routing processes to individual processors to provide extremely high-performance. The compact source code package requires as little as 384K of target system memory. Soft-ATM PNNI Routing Subsystem supports the Hello Protocol, PTSP PTSP PNNI Topology State Packet (Sprint-ATM) PTSP Perishables and Temperature Sensitive Products PTSP Public Transportation Subsidy Program PTSP Potential Trouble Source Person (Scientology) acknowledgements and retransmission. It is designed to handle in excess of 500 calls per second and includes 78 statistical parameters. "PNNI Routing is important because it eliminates the excessive time and cost associated with the manual provisioning of static routing. It allows users to define specific QoS parameters so that PNNI can dynamically select the best path based on the QoS requirements," said Ethan Harris, president of Harris & Jeffries. As with all Soft-ATM subsystems, Soft-ATM PNNI Routing Subsystem comes with the Harris & Jeffries Interoperability Guarantee which guarantees that products developed using H&J source code will interoperate with any other equipment that complies with The ATM Forum standards. Soft-ATM PNNI Routing Subsystem has been optimized for and pre-integrated with all H&J Soft-ATM subsystems, currently available are: ATM Signalling (UNI 3.0, 3.1, 4.0 and PNNI Signalling), ILMI ILMI Integrated Local Management Interface ILMI Interim Local Management Interface ILMI Interim Link Management Interface (ATMF) ILMI Illinois and Michigan Canal National Heritage Corridor (US National Park Service) , IP over ATM, LAN Emulation Client, LAN Emulation Server (LES, BUS, LECS See LANE. ), Frame Relay to ATM Interworking (standard) interworking - Systems or components, possibly from different origins, working together to perform some task. Interworking depends crucially on standards to define the interfaces between the components. (FRF FRF The ISO 4217 currency code for the French Franc. .5), and Frame Relay to ATM Service Interworking (FRF.8). The company's products also include High-Performance Frame Relay, X.25 and PAD, SDLC (Synchronous Data Link Control) The primary data link protocol used in IBM's SNA networks. It is a bit-oriented synchronous protocol that is a subset of the HDLC protocol. See SNA, DLC and Microsoft DLC. 1. and LLC software packages. Pricing and Availability The company said Soft-ATM PNNI Routing Subsystem will be available in December. Pricing of each Soft-ATM subsystem ranges from $15,000 to $80,000 per development license depending on configuration. Volume discounts may apply. About Harris & Jeffries, Inc.
