Abstract: The invention interconnects stacks executing the same protocol in the same node by means of a software implemented input/output device, thereby eliminating the need for physical resources otherwise required for data communication between the stacks. First and second connection objects are built in the virtual device in association with the first and second stacks, respectively. An association is also built between the first and second connection objects, thereby enabling communication between the stacks via the first and second connection objects.
