public class MPLSSignalingInterfaceMgmt

extends java.lang.Object

This MPLSSignalingInterfaceMgmt class provides the CR-LDP with interface functions to establish a LSP. This class recieves signaling informations(MPLSSignalingInfo class) that has Label request or mapping informations from the CR-LDP to allocates requested resources to a LSP.

 When the MPLSSignalingInterfaceMgmt receives a Signaling message from the 
 CRLDP, it collects resource informations whether it is available and then it 
 performs Lable request/mapping procedure to establish a LSP.
 The Informations of the Label mapping is recorded at the MPLSForwarding 
 Table.
