Frame relay

Configuring Frame Relay Services

Frame relay is a high-speed, packet-switching WAN protocol that connects geographically

dispersed LANs. Frame relay is a connection-oriented protocol, which means that it relies on

end-to-end paths between devices connected across the network. It implements these connections

using permanent virtual circuits (PVCs) or switched virtual circuits (SVCs). This manual describes

how to configure frame relay services on a Nortel Networks router.

PPP

Configuring PPP Services

Point-to-Point Protocol (PPP) creates an interface between peer routers to allow them to exchange

data. PPP also allows peers to negotiate and determine data link and network layer options. When

negotiations complete successfully, PPP encapsulates the data and transmits it over the link. This

manual describes how to configure PPP services on a Nortel Networks router.

SMDS

Configuring SMDS

Switched Multimegabit Data Service (SMDS) is a public, high-speed, packet-switched network

service that enables you to connect local area networks across wide area networks. SMDS provides

connectionless data transfer across a wide area network without establishing a logical end-to-end

connection.

To send information across the network, SMDS divides data into fixed 53-byte cells.

The use of cell technology makes SMDS well suited for traffic that consumes high bandwidth for

short periods of time. This manual describes how to configure SMDS services on a Nortel

Networks router.
