Abstract
Arbitration apparatus and method coordinate access to an output of a routing device in a packet switching network. Access to the output is granted to requests having the highest priority in a current arbitration cycle. For requests having the same priority, access is granted to the first of such requests received. Before granting a request, the arbitration apparatus ensures a receiving input buffer has sufficient space for a data packet, as well as any higher priority traffic.
