MENLO PARK, Calif., Aug 10, 1993 -- Cisco Systems and IBM have signed an OEM agreement under which Cisco is licensing IBM's Advanced Peer-to-Peer Networking (APPN*) technology for use in its family of internetwork routers.

Under the terms of the OEM agreement, Cisco is licensing from IBM the source code and intellectual property rights necessary to implement APPN Network Node routing in its products.

Pete Soutter, IBM's director of Networking Systems OEM Operations, said, "We are very pleased to expand our OEM business with Cisco to include this critical networking technology. This is part of an ongoing program of IBM's to facilitate the availability of high-quality, compatible APPN products from a wide variety of vendors."

Michael Zadikian, Cisco SNA product manager, said, "Cisco plans to offer our users who require SNA peer-to-peer networking the industry's most full-featured APPN implementation. Licensing the source code directly from IBM -- rather than from an alternative APPN source -- will assure our mutual customers of compatibility with IBM's end systems and networking products in the near term, and will also provide greater access to IBM's APPN technology."

Cisco Systems, Inc. is the leading worldwide supplier of high-performance, multimedia and multiprotocol internetworking products, including routers, bridges, communication servers and router management software. Cisco technology is used to build enterprise-wide networks linking an unlimited number of geographically dispersed LANs and WANs, including IBM SNA networks. In the United States, Cisco is traded over the counter under the NASDAQ symbol CSCO.
