Question
Consider the following situation and indicate whether you would use frame relay, ATM, MPLS, or Carrier Ethernet services. Assume that the facilities are available and “competitively” priced. For the following situation, determine which services could be used to satisfy the functional requirements of the application. For this situation, select the service(s) you would recommend and explain the reasons for your choice.
Please watch the youtube video about frame relay technology as part of your research: http://www.youtube.com/watch?v=FWZgqUDQc0c
a. You have a national WAN with about a half dozen locations in relatively remote areas. The transmission facilities are varied and include radio links, satellite links, and phone links using modems. The data rates are relatively modest.
Explanation / Answer
- In my point of view the Frame Relay is the best option for the functional requirments of the application.
Why because it is the most popular WAN service from many decades.
- Comparing with the VPN and ATMs technology the Frame Relay is still the best one for any kind of applications.
- The Frame Relay is most popular because of its feature,benefits and it is very lowest cost compare to the WAN services.
- Even in technical prospective the Frame Relay can convert the physical interface into the virtual interfaces.
So by using the virtual interface the Frame Relay can handle the network with single serial interface.
- The reason for picking up the Frame relay is mainly because it has very high performance packet switched WAN protocol which uses statistical multiplexing and variable length packets.
- The features like built-in congestion notification and traffic shaping capabilities are part of Frame Relay.
- The Frame Relay has been around since the late 1980s and still this technologies most popular. Even there are technology like MPLS which are quickly rising in popularity but Frame Relay is still a popular WAN protocol.
- If there are large number of users and applications involved so that a large number of virtual circuits are needed even though the number of locations is mall. Then each customer can get a private line to a frame-relay node called a virtual circuit through the Frame Relay cloud.
- In cloud we can store and manage huge amount of any kind data like user data and business data.
- Even in OSI model the Frame Relay operates at Layer 2 Data link.
Even though we have national WAN in many locations and we have all the links like radio and satellite links the Frame Relay can effectively distribute the data and secure the applications functionality.
