Abstract
A packet switching communication network (10) includes a number of switching nodes (16). The switching nodes include a switch (18) and at least one data processor (20). When selected packets (34), as identified by routing codes (40), arrive at one of the switching nodes (16), they are passed (58) to the data processor (20). The data processor (20) is configured to perform a network processing function, such as packet broadcasting (74) or error correction (60). In performing these functions, user data (38) conveyed by the selected packets (34) are processed to generate processed packets. The processed packets are re-introduced to the switch (18) and routed onto their destinations.
