Between grids and networks gridenabled network control planes

Purpose This article seeks to introduce the concept of the GridGMPLS control plane architecture with focus on new services, models, and interoperability issues of GridGMPLS G2MPLS and GMPLS control planes. The purpose of this activity is to design, implement and test extensions of the GMPLS Control Plane that can enable the paradigm of a G2MPLS network. Designmethodologyapproach The approach deploys extended GMPLS implementations aiming to facilitate bandwidth provisioning to Grid users. Findings G2MPLS is a Network Control Plane architecture that implements the concept of Grid Network Services. GNS is a service that allows the provisioning of network and Grid resources in a singlestep through a set of integrated procedures. By providing a unified networkGrid infrastructure the control plane can adapt to the demands of applications having intensive requirements on both computational and network resources. Research limitationsimplications The project delivers the prototype implementation of G2MPLS. Consideration should be given to involving the vendors of the optical equipment in the development process to incorporate the project findings into their operating systems. Practical implications The G2MPLS protocol stack has been designed to be compatible with the ASONGMPLS architecture. This could lead to possible integration of Grids in the existing operational networks, by overcoming the current limitations of Grids running over dedicated networks with their own administrative procedures. Originalityvalue The paper provides the description of Grid Network Infrastructures with a common and transversal Control Plane approach based on G2MPLS, in which Grid resources and optical network resources are both controlled by the same Control Plane, seamlessly spanning the different Control and Management domains of the network.
