Current GMPLS protocols can be used in a Grid enabled environment by properly defining a new interface between Grid and Transport layers. However, the asymmetric nature of Grid traffic makes GMPLS inefficient when establishing bidirectional connections. The User to Grid traffic is unlikely to be the same as the Grid to User traffic; whilst the location of the processing sites may be of no importance to the user, the destination address of the Grid to User downstream is the same for all the different flows akin to the same job. This may result in asymmetric resource allocation throughout the network. We propose and experimentally evaluate an implementation for a middleware interface as well as a novel scheme that reduces blocked job requests due to lack of network resources in such environment.
