  • running a first operating system and a second operating system on a computer system, the first operating system having a first network protocol stack including a first transmission control protocol (TCP) layer and the second operating system having a second network protocol stack including a second TCP layer;

    establishing a logical connection between the first and second TCP layers, including creating, by the first TCP layer, a first TCP control block corresponding to the logical connection, and creating, by the second TCP layer, a second TCP control block corresponding to the logical connection; and

    coupling the first TCP control block to the second TCP control block, including executing instructions, by an entity that accesses the first and second TCP control blocks, that are specialized for a situation in which the first and second TCP control blocks correspond to the same logical connection.
