Abstract
Communication apparatus includes multiple interfaces configured to be connected to a network so as to receive and transmit data packets having respective packet headers that includes a basic header record and one or more optional records. Parsing instructions specify one or more types of the optional records and indicate, for each specified type, an offset within an optional record of the specified type. Upon receiving each packet, routing logic parses the basic header record in the packet, parses the one or more optional records so as to identify any optional records of the one or more specified types, extracts header data from the identified optional records at the offset indicated for the specified type, and processes and forwards the data packets via the interfaces to the network in accordance with information parsed from the basic header record and the extracted header data.
