The PPP Banyan Vines Control Protocol (BVCP)
Alternative Format: Original Text Document
RFC 1763 PPP BVCP March 1995 1. Introduction PPP has three main components: 1. A method for encapsulating multi-protocol datagrams. 2. A Link Control Protocol (LCP) for establishing, configuring, and testing the data-link connection. 3. A family of Network Control Protocols for establishing and configuring different network-layer protocols. In order to establish communications over a point-to-point link, each end of the PPP link must first send LCP packets to configure and test the data link. After the link has been established and optional facilities have been negotiated as needed by the LCP, PPP must send BVCP packets to choose and configure the VINES network-layer protocol. Once BVCP has reached the Opened state, VINES datagrams can be sent over the link. The link will remain configured for communications until explicit LCP or BVCP packets close the link down, or until some external event occurs (an inactivity timer expires or network administrator intervention). 1.1. Specification of Requirements In this document, several words are used to signify the requirements of the specification. These words are often capitalized. MUST This word, or the adjective "required", means that the definition is an absolute requirement of the specification. MUST NOT This phrase means that the definition is an absolute prohibition of the specification. SHOULD This word, or the adjective "recommended", means that there may exist valid reasons in particular circumstances to ignore this item, but the full implications must be understood and carefully weighed before choosing a different course. MAY This word, or the adjective "optional", means that this item is one of an allowed set of alternatives. An implementation which does not include this option MUST be prepared to interoperate with another implementation which does include the option. Senum
