The design and deployment of grid environments for remote instrumentation services represent a key challenge for high-speed next-generation networks: not only is it necessary to implement a (G)-MPLS backbone offering Quality of Service at IP level, but it is also essential to design and develop new control plane mechanisms for dynamic resources allocation in explicit and optimized way. To this goal, we introduced the Grid Network Resource Broker (GNRB), a new architectural entity, which acts as an intermediate between the network and the grid environment. This chapter focuses on the design of the Path Computation Element, a key building block of the GNRB, which performs LSP path computation with QoS constraints. Several tests have been carried out to verify its applicability, in terms of LSP set-up time, to a grid environment scenario.
