Accelerating data transfer in a virtual computer system with tightly coupled TCP connections

摘要

First and second operating systems of a virtual computer system can communicate using respective first and second network protocol stacks, by employing procedures that are specialized for a situation in which a TCP control block of the first stack and a TCP control block of the second stack correspond to the same logical connection. In this case, various TCP requirements can be bypassed by coupling the TCP control blocks, reducing or eliminating data copies and providing other efficiencies.
