Abstract
Systems and methods for managing packet memory. Various clients in a router need to read from and/or write to the contents of individual packets. In one embodiment, all accesses to packet memory are via a packet manager. Individual clients are issued packet handles to use in identifying particular packets to the packet manager. The packet manager translates between the packet handles and pointers to packet memory locations. To assure robust performance after restarting the packet manager, each packet handle indicates which run version of the packet manager was responsible for generating the handle. The packet manager refuses requests for packet access using handles generated by previous versions.
