Frame Relay is a packet switched connection orientated network. It is in the physical and data link layer of the OSI model. It is a virtual connection between devises, it can transmit data, video and voice this is done via frames and it supports a bandwidth of up to 1.5M and up.
What does packet switched connection oriented mean? This means that there has to be a connection made between two devises before any data can be sent or recieved. Why it came about: When it first emerged it was a less complicated version of the X.
25 protocol. Cisco helped to standardise it. It was to be used as a transport method via Integrated Services Digital Network (ISDN) interfaces. It then became a standalone technology, apart from ISDN as ISDN was too slow .
Why so popular: Frame Relay is extremely popular as:
- To configure a router to the ways of frame relay is fairly easy to do
- Uses less equiptment
- Not complicated to use
- It has a high bandwidth
- Is quite reliable and most importantly
- It doesn’t cost that much.
Frame Relay is classified under the same class as ATM (Asynchronous Transfer Mode). It is used for telecommunications networks and transfers data voice and video. It is a widely used WAN protocol. It is used between Local Area Networks (LAN) over the Wide Area Network (WAN). All users get a personal line to a Frame Relay node. These nodes are enabled, to point frames in the right direction with the smallest amount of processing required. The link layer has a large address field in frame relay. The network deals with the transmission of these data files over a path which changes quite often. This path is invisible to to the users.
Error handling: Frame relay does not try to fix any errors that may be trying to be transmitted; it lets the.
