Performance of MPLS
As we described in Chapter 1, Multiprotocol Protocol Label Switching has certain significant characteristics due to integration of the ATM Quality of Service and signaling, and IP forwarding functionality. MPLS forwards the packets through fixed length labels and provides traffic engineering to guarantee the Quality of Service requirements. These concepts can also be extended to satellite networks and the advantages should be realized. To demonstrate such feasibility, we provide a simulation model for MPLS over satellite network. Examples of TCP and UDP flows are considered and QoS performance in terms of packet loss, delay, and jitter is discussed.
