Abstract

A method and system for byte slice processing of received data packets at a packet switch is provided. When a data packet is received at the packet switch, the packet is buffered by a buffer manager and then processed by a processor to determine to which outgoing port to send the packet. When aggregate bandwidth of all incoming ports is high, resources of the processor can be optimized to minimize hardware logic, and maximize a processing rate of the switch. One optimization is to limit the number of bytes that are sent to the processor based on some preliminary identification of packet type together with known configuration information about the receiving port interface type, so that only information within the data packets that is deemed necessary is sent to the processor.
