SYSTEM FOR SELECTING A CONNECTIVITY MECHANISM

摘要

An address resolver system that assists a node in an IPv6 network to select an address for connectivity with a node in an IPv4 network when both DSTM and N AT- PT transition mechanisms are available. Native connectivity can be achieved by preferring an encapsulation or tunnelling mechanism such as DSTM where possible over a translation mechanism such as NAT-PT. A range of encapsulati on and translation mechanisms are envisaged. The resolver determines capabiliti es of the node and of the application that requires the address in order to mak e the selection.
