Abstract: A router and method for routing table cache population technique is disclosed. In particular, the illustrative embodiment routes packets through it more quickly than comparatively expensive routers in the prior art. The present invention recognizes that a fast router has small routing table cache that has a high hit ratio and that a high hit ratio can be achieved with a small routing table cache by predicting which entries will be needed in the routing table cache in the future and by populating the routing table cache with those entries before they are needed.

Abstract: A method and system for allocating persistent private network addresses between private networks. An Internet Protocol (“IP”) address of a multimedia device (e.g., a Voice-over-IP (“VoIP”) device) is publicly available and the device, the device's location or the device's user may be identified and become the target of a hacker. Persistent private IP addresses may be used for such multimedia devices. Persistent private IP addresses are unique and persistent for a duration of a multimedia session between two private networks. The persistent private IP addresses are not routable on a public network like the Internet. The persistent private IP addresses allow a first network device on a first private network to establish a data session with a second network device on a second private network over a public network such as the Internet.
