Class AddressResolver

java.lang.Object

org.mjsip.server.sbc.AddressResolver

All Implemented Interfaces:

TimerListener

Direct Known Subclasses:

AddressResolverKeepAlive

public class AddressResolver
extends java.lang.Object
implements TimerListener

Class AddressResolver maintains address binding. It maps socket addresses into other socket addresses.

Class AddressResolver can be used to maintain a reference to the actual address to be used to reach a remote node, against to the address optained in other ways. For example, it can be used to maintain correct remote address mapping for symmetric NAT traversal.
