public class PeerLSRMgmt

extends java.lang.Object

This class manages the peerLsrList in the sCR-LDP module. It has functions to find PeerLSRs and to create PeerLSRInfo to maintain peer info. +------------------------+ (1) When the sCR-LDP is started, it creates | PeerLSRInfo |+ a peerLSRInfoTable to maintain peer | - PeerLSR information ||+ LSR information to support MPLS signaling| - Interface Info ||| messages exchanging | - IP address Info ||| (2) If there is no peerLSR infomation | ||| that is requested to establish a LSP, +-----------.------------+|| Label request will be rejected. +---------.-------------+| +------.--------------+ . +=========================+ . | sCR-LDP | . to/from a peerCR-LDP | - peerLSRInfoTable........... to/from a peerCR-LDP | - ControlBlockTable....... | - Signaling functions | . +=========================+ . . +--------.---------------+ (3) When the sCR-LDP receives a Label | CRLDPControlBlock |+ request message form the peer CR-LDP, | - LSP information ||+ thesCR-LDP creates a CRLDPControlBlock | - Label Request funcs ||| to establish a requested LST | - Label Mapping funcs ||| (4) The CRLDPControlBlock has all of | - Notification funcs ||| Label Request, Mapping and Release +------------------------+|| functions. So It performs a LSP +-----------------------+| establish, management and release. +---------------------+
