FR (Frame Relay) is a packet-oriented WAN technology use for connecting remote offices over the internet or WAN. Frame-relay consider to be cost effective solution and most ISPs across the globe provide frame relay services.
Frame-relay provides the dedicated connection called the PVC which is used to form logical end-to-end links mapped over a physical network. You can connect LANs with backbones Over T1/E1 lines using frame-relay.
Features of Frame relay:
Some features of frame relay are as follow:
- Frame relay provides connection-oriented virtual circuit service.
- Frame relay can detect transmission errors.
- Frame Relay connections are often given a committed information rate (CIR), which provide guarantees that the connection will always support the committed rate or bandwidth.
- Frame length is variable, the maximum frame length allowed in the 1600B above.
- Frame Relay is a broadband packet switching and has the transfer rate up to 44.6Mbps.
- Error rate is very low with frame-relay using optical fiber as the transmission medium, reducing the error check for the overhead and improves the network throughput.
- Frame relay uses variable length frame-based asynchronous multiplexing technology, therefore it is used for data transmission, and not best suitable for voice, video, or other delay time-sensitive information transmission. However, under certain circumstances, it can be used for voice and video transmission.
