Lab 14: Configuring Frame Relay Networks, Traffic Shaping, OSPF, & DLSw/LLC2 ”Part IPractical ScenarioMost networks don't grow at an even, incremental basis. Some portions of the network might have faster newer links, while other parts of it could be older and slower. Oversubscription of links can be a common problem in Frame Relay networks. Traffic shaping helps address this problem. Enabling traffic shaping allows greater control over bursty traffic and the amount of data sent out an interface at any given time. This greatly helps the problem of high-speed links pushing too much data toward lower-speed links. This practice lab challenges you to configure traffic shaping in a multipoint Frame Relay network. Lab ExerciseThe Jet Propulsion Laboratory (JPL) receives large graphic images from several telescopes. When the JPL receives these images, it immediately downloads them to Cape Canaveral in Florida and Houston , Texas. These images can be large at times and quickly saturate the links of the two NASA sites. To control these sudden bursts of large data, the JPL wants to deploy Frame Relay traffic shaping (FRTS). Use the following guidelines for your design and FRTS configuration:
