A METHOD AND SYSTEM FOR ANALYSING A DATA PACKET OR FRAME

摘要

A method of categorizing a data packet or frame, such as an Ethernet packet or a Sonet frame, where one or more features of the packet or frame are identified and a corresponding priority assigned. At least two priorities, a higher and a lower priority, are used. If none of the sought after features are identified, such as if the packet or frame is of an unknown type, the packet or frame is assigned the higher priority.
