Support for Netware Link Service Protocol is the main enhancement in the latest release of Proteon's Open Route internetworking software.
This software is found on all Proteon's routers and is also OEMd by IBM, Digital, Motorola and AT&T for their switching products. Release 2.2 supports NLSP, which allows exchange of information between routers on IPX networks. The network layer protocol improves on the IPX Routing Information Protocol, making routing options more flexible and allowing larger networks to be designed.
Also on the IPX front, the new release implements version 2.0 of IPXWan, a link management protocol for wide area networks, and provides other IPX enhancements to improve load sharing, bandwidth management and efficiency of routing.
"Proteon now has more than a decade of development invested in its Open Route software," commented Robert Koch, director of product marketing. Support for NLSP is critical for large, complex networks based on Netware, he added.
"As a link state routing protocol, NLSP fundamentally changes the way routing information is handled in an IPX network," continued Koch. "Each router in an NLSP environment keeps a complete topological map of the entire area network in its memory. This provides increased network performance and accurate and updated path information."
Proteon's implementation of NLSP was done inhouse. The company has been working on link state routing protocols for five years and also supports IS-IS, OSPF and Integrated IS-IS.
Support for the new release of IPXWan allows for dynamic assignment of Netware addresses. The product sets up a 'master' and 'slave' side to each Wan connection. It allows Proteon routers to communicate with other routers that support IPXWan, including Novell's Multiprotocol Router.
Other enhancements to Proteon's implementation of IPX give users three options for routing traffic - unnumbered RIP (Routing Information Protocol), RIP and Service Advertisement Protocol (SAP) static routes, and RIP default route.
To help use bandwidth more efficiently, the routers can now be configured to keep unwanted IPX Netbios traffic off the Wan. Network managers can configure, on a circuit basis, the interval between broadcasts of RIP or SAP packets, and the packet size.
Open Route is shipping now with Proteon's CNX and RBX routers and its Globetrotter remote access device.
