  • System and method for performing cascaded lookups to forward packets
    Patent number: 8090805
    Abstract: Cascading a lookup over multiple lookup tables when performing multicast forwarding involves accessing a first lookup table based on at least part of a multicast destination address included in a packet header. The first lookup table identifies the portion (e.g., one or more entries) of a second lookup table in response to a key generated from a first portion of the packet header. The portion of the second lookup table can be accessed based on a second portion of the packet header. The second lookup table identifies at least one output interface via which the packet should be output. Such systems and methods may, in some embodiments, allow existing hardware to be used to support a new addressing format that involves larger addresses than were previously supported by that hardware.

  • Forward error correction in packet networks
    Patent number: 7328393
    Abstract: Methods and apparatus are provided to allow reliable data transport in a packet-based network. A network node encodes error correction packets associated with data packets at a network-layer and forwards the error correction packets with the data packets. The error correction packets are decoded as needed to recover data packets lost or dropped during transmission. The mechanisms are applicable for unicast and multicast networks and function even with network topology changes.
