Class PhysicalNetwork

java.lang.Object

net.onrc.openvirtex.elements.network.Network<PhysicalSwitch,PhysicalPort,PhysicalLink>

net.onrc.openvirtex.elements.network.PhysicalNetwork

All Implemented Interfaces:

OVXSendMsg, LLDPEventHandler

public final class PhysicalNetwork
extends Network<PhysicalSwitch,PhysicalPort,PhysicalLink>

Singleton class for physical network. Maintains SwitchDiscoveryManager for each switch in the physical network. Listens for LLDP packets and passes them on to the appropriate SwitchDiscoveryManager. Creates and maintains links after discovery, and switch ports are made discoverable here. TODO: should probably subscribe to PORT UP/DOWN events here
