Internal parallel system channel

An apparatus and method for providing connectivity using physical and emulated links so as to allow for simultaneous connection of such nodes particularly in a parallel sysplex environment. A method and apparatus that provide connectivity in a computer network environment that includes a plurality of nodes, interface links and at least one central electronic complex divided into one or more physical and or virtual sub-environments. A first control program is provided in the central electronic complex in order to establish a first command process layer and a first transfer process layer within this first control program for handling data. The first command process layer is then linked to the first transfer process layer in this control program. A second control program is also provided in the central electronic complex in order to establish a second command process layer and a second transfer process layer within this second control program for handling data. The second command process layer is also linked to the second transfer layer in said second control program. Ultimately a link is emulated between the first transfer process layer and the second transfer process layer; and a physical interface is provided between the first transfer process layer and the second transfer process layer without affecting any of the logical interface(s) between the transfer process layers.
