executeTask

boolean executeTask(Runnable task)

Execute the specified task asynchronously.

transmit

void transmit(List<org.apache.commons.lang3.tuple.Pair<SalPort,Packet>> packets)

Transmit all the given packets.

Parameters:

packets - A list of packets to transmit. The left of each elements indicates the egress switch port, and the right indiciates a packet to transmit.

getRouteResolver

RouteResolver getRouteResolver()

Return the packet route resolver associated with the system default routing policy.

Returns:

A RouteResolver instance on success. null if the routing management is already closed.

getRouteResolver

RouteResolver getRouteResolver(Integer id)

Return a packet route resolver.

Parameters:

id - The identifier of the path policy.

Returns:

A RouteResolver instance if found. null if not fonud.

addFlow

Add the given VTN data flow.

Parameters:

builder - A VTNFlowBuilder instance which contains data flow to be installed.

Returns:
