Methods

o instance 
 public static SignallingPeerImpl instance()
Returns the only instance of the SingallingPeerImpl according to Singleton Pattern. The instance is created if necessary.

Returns:
The only instance.
o setPeer 
 public void setPeer(SignallingPeer peer_,
                     int port_)
Stores the reference to the SignallingPeer in given port.

Parameters:
peer_ - The reference to the peer
port_ - The (switch) port where the peer lives
o getPeer 
 SignallingPeer getPeer(int port_)
Returns reference to the peer in given port.

Parameters:
port_ - The number of the (switch) port
Returns:
Reference to the SignallingPeer
o setPeerPort 
 void setPeerPort(int remotePort_,
                  int localPort_)
Sets the neighbour port.

Parameters:
localPort_ - The local port number
remotePort_ - The adjacent port number of the neighbour switch
o getPeerPort 
 int getPeerPort(int localPort_)
Returns the neighbour port.

Parameters:
localPort_ - The local port number
Returns:
The adjacent port number of the neighbour switch
o connectionSetup 
 public SignallingContext connectionSetup(Long connID_,
                                          int fromPort_,
                                          VPIVCI fromVCC_,
                                          InetAddress dest_,
                                          SignallingContext oSide_) throws RemoteException
Creates a new signalling context. Called from the neighbouring node during a connection setup phase.

Throws: RemoteException
If remote method call fails
o connectionSetup 
 public SignallingContext connectionSetup(Long connID_,
                                          VPIVCI fromVCC_,
                                          InetAddress dest_,
                                          SignallingContext oSide_,
                                          InetAddress clientIP_,
                                          InetAddress prevRouterIP_) throws RemoteException
Creates a new signalling context. Called from the neighbouring node during a connection setup phase.

Throws: RemoteException
If remote method call fails
o ping 
 public void ping() throws RemoteException
A method for the adjacency protocol. Called by neighbouring signalling peers to ensure that the link is up.

Throws: RemoteException
If remote method call fails
o tell 
 public int tell(InetAddress IP_,
                 SignallingPeer peer_) throws RemoteException
A method to set up the connection between adjacent signalling peers. Called by each of the neighbours when they want to inform of themselves.

Returns:
The port number where the caller resides
Throws: RemoteException
If remote method call fails
o routeAdded 
 public void routeAdded(Route r_)
o routeDeleted 
 public void routeDeleted(Route r_)
