Use the Web address Http://www.ietf.org/rfc/rfcAbCd.txt, where AbCd is the protocol RFC number. For your convenience, the protocols are listed here with their title, acronym, RFC number, and a short description of purpose.

Border gateway protocol (BGP) RFC 4271

A path vector protocol, BGP is the core routing protocol for use among autonomous networks. It maintains a table of network IP prefixes that provide reachability among autonomous systems.

Common open policy service (COPS) RFC 2748 also 4261

A simple query and response protocol that exchanges information between a policy server and its clients in order to support control of QoS signaling protocols.

Differentiated services (DiffServ) RFC2475

To ensure a packet is forwarded in accordance with its QoS requirements, DiffServ classifies and marks packets to receive a particular per-hop forwarding procedure.

Generalized multiprotocol label switching (GMPLS) RFC 3945

A generalization of MPLS (RFC 3031) that clearly separates the functions of the forwarding plane and the control plane so as to cope with the signaling and routing functions associated with time-division, wavelength-division, and space-division switching and related equipment.
