Implementation Issues of Managed Bandwidth Service: The Case of GRNET

This paper describes the design and the implementation of the Managed Bandwidth Service (MBS) in a high speed backbone network as well as a management tool for the service. The service was designed taking advantage of features provided by the MPLS technology and also using the DiffServ architecture. So, it uses L2 MPLS VPNs to provide point to point connection and also marks the traffic in order to pass from certain priority queues (to provide guaranteed bandwidth). It also enables traffic engineering characteristics in order to provide load balancing on the network as well as fast rerouting in case of link failure. In addition we implemented a management tool for the service. The scope of this tool is to allow the users to manage their MBS requests (make a new one, edit, delete or view a request). Also the tool performs admission control and produces the necessary configuration that must be applied on the network in order to implement every service’s request. This service was desig...
