Network engineering towards efficient resource on-demand in grid computing

The essence of grid computing is to provide efficient resource on demand (RoD). This paper addresses this challenge from the perspective of network, the living platform of grid, by providing effective quality of service (QoS) mechanisms (both IntServ and DiffServ) inside the grid networking environment. Particularly, the efficiency of this QoS mechanism is maximized by policy-based management taking care of flexible control of QoS parameters/components and active networks technology looking after the fast delivery of various QoS configurations. An early experiment exemplified the current implementation status.
