When applications connect to a data pipe, which is located on the same system as the connecting applications, the data pipe is considered a local pipe. That is, local media is used to pipe the data. If, however, an application on a different system is to access the pipe, the pipe is transitioned from a local pipe to a cross-system pipe, in which an alternative non-local media is used to pipe the data. The application causing the transition and any other applications to subsequently connect to the pipe use the cross-system pipe. Any local applications still allocated to the pipe are transitioned, such that they now access the cross-system pipe, instead of the local pipe. Likewise, when an application disconnects from a cross-system pipe, such that all remaining connections to the pipe are local connections, the pipe is transitioned from a cross-system pipe to a local pipe.
