The frame relay is being used for a number of reasons. Some of the important reasons are as follows:
1. Higher data rates.
2. It allows transfer of bursty data.
3. It has lower overheads.
• Let us discuss these points one by one.
1. Higher Data Rates
It allows transfer of bursty data.
• If the LANs located at physically distant places are to be connected to each other then there are two options available to do this.
1. Interconnect them using the T lines.
2. Interconnect using the frame relay.
2. Can handle bursty data:
• The data being sent from a source to destination is not of continuous/constant nature.
• Instead it is bursty in nature. That means a large amount of data (data burst) is sent suddenly, then for sometime there is very little or no data.
• The T-lines are not equipped to handle such bursty data because they offer a constant data rate.
• The frame relay can tackle this problem. It supports a minimum average data rate and can handle the bursty data.
3. Lower overheads:
• In frame relay network, there are no acknowledgements sent from the switches back to the sender.
• There is no intermediate error check. The error checking takes place only at the destination.
• The intermediate host/switch does not keep a copy of the packet forwarded to the next host/switch. This saves a lot of memory space of the hosts and switches.
• All this lead to reduced overheads.
