IP networks, long lacking the high availability of their voice and data counterparts, are being improved to recover from failures more quickly and to reduce packet loss. Cisco Systems Inc. and Alcatel SA are targeting such deficiencies with new software for their respective routers. While the improvements are being aimed initially at service providers, enterprises can expect the same features to be added to corporate versions of the products by year's end.

Cisco is combining nonstop forwarding with stateful switch-over to enable packets to continue to flow with nearly no packet loss, even as a router reverts to a standby processor. That feature, to be available for three service-provider-designed routers next month, will be added to enterprise routers later this year, said Cisco officials, in San Jose, Calif.
