ABSTRACT:
A structure for coupling together addressably disparate nodes, such as IPv4 nodes and IPv6 nodes, without the use of an application level gateway. Instead, the system includes two executable applications, HEART and ECHO, that avoid the necessity of an application level gateway. In general, HEART and ECHO cooperate with each other through a network address translator-protocol translator (NAT-PT) to cause the NAT-PT to temporarily assign an IPv4 address to a control session between the IPv4 and IPv6 nodes and also prevent the control session from timing out due to lack of timely communications between the IPv4 and IPv6 nodes.
