Abstract

See full text

In one embodiment, configurable policy-based processing of packets is performed, including, but not limited to, using user-configurable parameters to adjust control-plane allocation of resources used in processing of packets. In one embodiment, these resources include, but are not limited to, processing by fast path or slow path forwarding of packets; forwarding information base (FIB) entries, databases, and hardware processing elements; instantiation of sub-FIB databases; and/or selection of sub-FIB data plane entries for population of sub-FIB databases, a group of FIB entries is label switched traffic, fully expanded Internet Protocol routes, loopback addresses of packet switching devices in the network, label-switched to label-switched traffic, Internet Protocol (IP) to label-switched traffic, IP to IP traffic, and/or label to IP traffic. In one embodiment, a group of the plurality of different groups of FIB entries is defined upon how a route or label corresponding to a FIB entry was learned.
