public class PeerLSRMgmt

extends java.lang.Object

This class manages the peerLSRInfoTable in the sCR-LDP module. It has functions to find PeerLSRs and to create PeerLSRInfo to maintain peer info.

  The sCRLDP class is MPLS Signaling Protocol.
  

                                                +------------------------+                   
   (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        |                        |||

   (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  |||
