Packet header decoding

Packet header decoding is a fundamental task of every network appliance ranging from switches and routers to security appliances. It’s a straight-forward task of extraction of packet header fields for the purposes of subsequent classification. But straight-forward does not mean trivial. Fixed hardware structure of such component is limited in flexibility and possibilities of support of various network protocols. It’s not enough to parse basic network protocols such as IP and TCP/UDP. In today’s networks, the protocol stack can be very diverse. There is a vast number of encapsulation protocols and network overlays like TRILL, MPLS, 802.1q etc. Also, the extraction mechanism needs to deal with evolving structure of protocols used in computer networks.

Netcope steps up to this challenge by leveraging flexible, modular components for packet header decoding that can be configured to satisfy specific needs. Default configuration allows the payload to be preceded with several encapsulation headers including TRILL, MPLS, and 802.1q protocols.

Support of P4 language extends this possibility with standardized high-level description of supported protocol stack and subsequent actions performed on the traffic independently of specific hardware architecture. In other words, it provides total control over functionality of the card.
