Abstract
A route table providing a list of pointers to checksum values computed across routes of interest to a particular protocol. A method of updating the route table when a route is changed and also updating the checksum values is further described. Updates to the checksum value may be done using an exclusive OR process allowing for relatively fast, incremental updates to the checksum value.
