Abstract
Abstract A method for enabling data paths including the steps of receiving a request to enable a data path on a remote bus between a first processing apparatus and a second processing apparatus, determining whether the remote bus can handle the requested data path, and enabling the data path on the remote bus if the remote bus can handle the requested data path. In addition, an apparatus for enabling data paths including an apparatus for receiving a request to enable a data path on a remote bus between a first processing apparatus and a second processing apparatus, apparatus for determining whether the remote bus can handle the requested data path, and apparatus for enabling the data path on the remote bus if the remote bus can handle the requested data path.
