In April 1999, Ericsson acquired Torrent Networking Technologies, a USA-based start-up manufacturer of high-end Gigabit routers for public IP networks. The team at Torrent—now the Ericsson IP infrastructure group within the Datacom Business Unit—began rolling out its new AXI 540 Edge Aggregation Router during the fourth quarter of 1999. The AXI 540 router, which has been optimized to serve the edge of new public IP networks, is a natural fit in Ericsson’s expanding portfolio of data products. In this article, the author discusses the requirements for routers at the edge of the new public IP network, and presents the key technologies and architectural capabilities of the AXI 540 router, which was built to fulfill these requirements.
