What is a frame relay router?

In frame relay, the routers connected to remote networks are usually the DTE devices while the frame relay switch is usually the DCE device. The frame relay switches move data frames from the host networks across the WAN network to the remote DTE devices.

What is Frame Relay example?

Frame relay is a packet-switching telecommunications service designed for cost-efficient data transmission for intermittent traffic between local area networks (LANs) and between endpoints in wide area networks (WANs). The service was once widely available and implemented.

Which two devices are used on frame relay connection?

Devices attached to a Frame Relay WAN fall into the following two general categories: Data terminal equipment (DTE) Data circuit-terminating equipment (DCE)

Which address called Frame Relay virtual circuit?

Key Frame Relay LMI extensions include global addressing, virtual circuit status messages, and multicasting. The LMI global addressing extension gives Frame Relay data-link connection identifier (DLCI) values global rather than local significance. DLCI values become DTE addresses that are unique in the Frame Relay WAN.

What is Frame Relay connection?

Frame relay is commonly used to connect two or more LAN bridges over large distances. The iSeries system supports these frame-relay network connections: Frame relay direct network: Allows data that uses SNA or TCP/IP communications over a frame-relay network to move at speeds of up to 2.048 Mbps.

Which address called frame relay virtual circuit?

How is the frame relay address assigned to a computer?

As frames move from one network to another, Frame Relay labels each VC with a DLCI. The DLCI is stored in the address field of every frame transmitted to inform the network how the frame should be routed. The Frame Relay service provider or ISP assigns DLCI numbers or values.

What is frame relay present?

Each Frame Relay protocol data unit (PDU) consists of the following fields:

  • Flag Field. The flag is used to perform high-level data link synchronization which indicates the beginning and end of the frame with the unique pattern 01111110.
  • Address Field.
  • Information Field.
  • Frame Check Sequence (FCS) Field.
