Subject: 040.61 ANSNet and GatedD Al Weis, ANS The ANSNet/NSFNET routing software in use today, which is based on a derivative of an early version of Gateway Daemon (GateD), does not scale to support the future needs of the Internet. To alleviate this problem, Advanced Network & Services (ANS) has joined a consortium with IBM Corporation, TGV, Inc., and Cornell University to upgrade GateD, deploy it on the ANS Network and distribute it to the public domain. Currently, GateD is being used in commercial products by several router vendors. It will be upgraded to include support for IS-IS and BGP-4. Developers from ANS and IBM have been working on the GateD enhancements for about five months and are testing them at ANS headquarters in Elmsford, NY, the IBM T.J. Watson Research Center in Hawthorne, NY, and at Cornell. The first release will be introduced on the ANSNet by early February. It will be compatible with the existing software to ensure that there is no disruption in service. Once BGP-4 is deployed, there will be a dramatic reduction in the amount of routing overhead on the ANS backbone; the number of routing table entries will be reduced by at least 30%. Mid-level and enterprise networks attached to the ANSNet that also deploy BGP-4 will be able to do explicit routing. As the enhancements are tested and frozen, Cornell will provide them to the public domain. ANS and the consortium are offering to work with independent software vendors and router vendors to test the interoperability of their products with the new GateD enhancements.
