CrossComm to introduce advanced ATM capabilities at Networld+Interop; Will also give first demos of new CrossLAN Exchange.MARLBOROUGH, Mass.--(BUSINESS WIRE)--Sept. 17, 1996--CrossComm Corporation today said it will expand its advanced corporate intranet offerings by introducing several significant new capabilities for its ATM devices -- including LAN emulation See LANE. , IP over ATM, and switched virtual connections -- at Networld+Interop in Atlanta. The company will also host the first public demonstrations (in Booth 1436) of its new CrossLAN Exchange, the industry's first complete packaged solution that gives customers the ability to easily and transparently add the benefits of ATM throughput to their high-speed intranet servers -- while still maintaining their existing network infrastructure. "Along with the CrossLAN Exchange, CrossComm now offers network managers the most connectivity options to easily upgrade legacy networks and make use of the high throughput of ATM -- while maintaining their existing applications and infrastructure," said CrossComm Vice President of Marketing David Zwicker. "The new capabilities add support for the most advanced ATM Forum A membership organization founded in 1991 to promote ATM networking technology. It worked with ANSI and the ITU to set standards. Its first specification in 1992 defined the User-Network Interface (UNI). In 2004, the Forum merged with the MPLS and Frame Relay Alliance. standards, providing a powerful set of tools and solutions for building corporate intranets. They further endow the ATM products with a richer set of management capabilities, provide for mission-critical reliability and availability in multi-vendor networks, and ensure full interoperability with standards-based products from other vendors. And we're willing to demonstrate these capabilities on the show floor by helping companies analyze how they can easily add an intranet to their current networks. We want them to see that it's here -- today -- and that it works in real environments." New LAN Emulation Server, Software Upgrades Support ATM LANE Standard CrossComm will introduce a new ATM LAN Emulation Server, the XLES, and also will bring software support for the ATM Forum LANE 1.0 LAN Emulation standard to its XLT-F ATM Edge Router Also called an "access router," it is a router that sits at the periphery of a network. Contrast with "core router," which is a router that resides in the middle of the network. See router and WAN router. See also edge device. , the AES Edge Switch, and the XLX ATM Switch. LAN Emulation makes an ATM network transparent to the users, applications and internetworking devices that require Ethernet or Token Ring A local area network (LAN) access method developed by IBM. Conforming to the IEEE 802.5 standard, Token Ring uses a token ring access method and connects up to 255 nodes in a star topology at 4, 16 or 100 Mbps. LANs. 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. devices can send packets across the ATM network knowing only the destination MAC address. LAN Emulation also provides a multicast service that has the same function as the multicast and broadcast features inherent in shared LANs. The XLES contains three entities which provide essential LANE services: the LES LAN Emulation Server provides MAC address to ATM address resolution; the BUS Broadcast and Unknown Server applies the broadcast and multicast capabilities of a LAN to the point-to-point connection structure of ATM, and also supplements the LES by resolving unknown MAC addresses; the LECS See LANE. LAN Emulation Configuration Server tracks the various emulated LANs, identifying whether they are Ethernet or Token Ring, what their maximum frame size is, and what other defining characteristics exist. The XLES contains a powerful, dedicated RISC RISC in full Reduced Instruction Set Computing Computer architecture that uses a limited number of instructions. RISC became popular in microprocessors in the 1980s. i960 processor -- enabling it to support multiple emulated LANs on larger networks. Switched Virtual Circuits, IISP IISP Information Infrastructure Standards Panel (ANSI) IISP Interim Interswitch Signaling Protocol IISP Institute of Information Security Professionals IISP International Institute for Software Process and 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. Supported Both the XLT-F and the XLX now support Switched Virtual Circuits (SVCs). These connections between two ATM nodes are created only when they are needed, and are torn down when they are no longer required, or are not in use for a specified period of time -- enabling customers to build dynamic networks. Being able to set up SVCs on demand makes network operations more efficient by not wasting bandwidth when it is not needed. CrossComm supports both versions of the User Network Interface (UNI) signaling protocol It is a protocol used to identify signaling encapsulation. Signaling is used to identify the state of connection between telephones or VOIP terminals ( IP telephone or PCs or VoWLAN units ). List of signaling protocols:
Switched Virtual Circuits can be routed through multiple ATM nodes by using the IISP and a pre-standard version of PNNI inter-switch protocols. IISP (Interim Inter Switch Protocol) is used to exchange static routes information between switches to create SVCs across the entire ATM network. However, static routes require manual table insertion into each participating ATM switch. CrossComm's version of PNNI is a pre-standard implementation of the Private Network to Network Interface (PNNI) that allows the XLX switches to exchange dynamic routing The ability for a router to forward data via a different route based on the current conditions of the communications circuits. For example, it can adjust for overloaded traffic or failing lines and is much more flexible than static routing, which uses a fixed forwarding path. information -- eliminating the need for static routing Forwarding data in a network via a fixed path. Static routing cannot adjust to changing line conditions as can dynamic routing. See routing protocol. tables. CrossComm's implementation of PNNI also provides a fast converging re-route algorithm, giving more resilience to the network by providing an alternate path if the primary path should fail. IP Over ATM Supported The new software enhancements also support the RFC (Request For Comments) A document that describes the specifications for a recommended technology. Although the word "request" is in the title, if the specification is ratified, it becomes a standards document. 1577 standard, enabling network managers to build IP networks over ATM. This implementation provides routing at ATM data rates by creating direct connections between the ATM nodes participating in the Logical IP Subnetwork See subnet. .
