<div><p>Frame relay is a protocol for routing frames through the network
|
||
|
|
based on the IP address field (data link connection identifier)
|

|
in the frame and for managing the route or virtual connection. </p>
|

|
|
<div class="section"><p>Frame-relay networks in the U.S. support data transfer rates at
|
||
|
|
T1 (1.544 Mbps) and T3 (45 Mbps) speeds. You can think of frame relay as a
|
||
|
|
way of utilizing existing T1 and T3 lines owned by a service provider. Most
|
||
|
|
telephone companies now provide Frame Relay service for customers who want
|
||
|
|
connections at 56 Kbps to T1 speeds. (In Europe, Frame Relay speeds vary from
|
||
|
|
64 Kbps to 2 Mbps. In the U.S., Frame Relay is quite popular because it is
|
||
|
|
relatively inexpensive. However, it is being replaced in some areas by faster
|
||
|
|
technologies, such as asynchronous transfer mode (ATM). </p>
