Abstract
A data packet processing system is provided for a router having a multiprocessor architecture comprising a master node and a processor array of multiple slave nodes. A packet switching software of the router is partitioned into a main forwarding program which is loaded in the master node, and a set of procedures which is loaded into the slave nodes. The system assigns to each data packet a program counter which defines a sequence of procedural calls in the main forwarding program. By stepping through the program counter in the master node, each procedural call is forwarded to and executed by one of the slave nodes.
