This means enterprises will not need to remotely administer branch cluster controllers, utilize expensive data link switching (DLSw)-capable routers, or maintain costly front-end processors.
These enhanced features extend Bay Networks' Data Link Switching (DLSw) implementation with support for DLSw Version 2 which enables a single router to scale to support larger networks; multiple PU Type 1 devices to prevent SNA session timeouts; and DLSw Backup Peers for increased network availability.
Congo, Danube, Colorado, and Amazon also offer rich protocol support: Data Link Switching for NetBIOS traffic, IP routing, IPX routing, and bridging were all tested without failure.
Enhancements include Advanced Peer-to-Peer Networking (APPN) support for direct transport over Asynchronous Transfer Mode (ATM), Switched Multimegabit Data Service (SMDS) and Integrated Services Digital Network (ISDN); Data Link Switching Plus (DLSw+) enhancements, including SNA dial-on-demand routing (DDR) and DLSw Lite; and Boundary Access Node (BAN) capability.
0, which will begin shipping March 29, will contain such advanced SNA networking features as: -- The industry's first implementation of High Performance Routing (HPR) in a multiprotocol router -- A versatile prioritization scheme for allowing Data Link Switching (RFC 1795) networks to apportion bandwidth between NetBIOS and SNA traffic -- Boundary Access Node (BAN) for easier Frame Relay connections to SNA Front End Processors (FEPs) In addition to the new SNA enhancements which are now being offered with this NETBuilder software release, 3Com also announced the shipment of their NETBuilder Remote Office 52x series of routers that were introduced in November.
The NBRO 327 offers support for TCP/IP, IPX, XNS, AppleTalk, DECnet, VINES and OSI, as well as support for Data Link Switching (DLSw) and SNA over Frame Relay (RFC 1490).
0 also incorporates GUI support for SNA Express, including both Data Link Switching (DLSw) and SDLC to LLC2 conversion, Frame Relay, IPX/SPX KeepAlive Proxy, and Flash RAM File System parameters.
