Explain three circumstances that would necessitate the implementation of frame relays in corporate networks

Explain three circumstances that would necessitate the implementation of frame relays in corporate networks

Answers

Faith
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.
