Method for Establishing and Terminating Service Flow via Relay Nodes using Tunnel Mechanism

A method for establishing a tunneled service flow between a first peer node and a second peer node hidden from one another in centralized shared media of a digital telecommunication system comprising:

• initiating via the first peer node a request to a domain master for admission to establish the tunneled service flow, with required Quality of Service parameters, between the first peer node and the second peer node, the first peer node and the second peer node being hidden from one another;
• upon the domain master determining that the requested tunneled service flow cannot be supported:
• providing, by the domain master, a rejection to the request for admission to establish the requested tunneled service flow;
• and
• if the domain master determines that the tunneled service flow can be supported:
• defining, at the domain master, a single route through one or more relay nodes;
• defining, at the domain master, service flow parameters that support the requested tunneled service flow in the centralized shared media;
• reserving, at the domain master, resources needed to support the requested tunneled service flow;
• providing, by the domain master, an admission to establish the requested tunneled service flow, the admission including the single route;
• passing control messages between the first peer node, the one or more relay nodes, and the second peer node to establish the requested tunneled service flow as the tunneled service flow;
• and
• after completion of establishment of the tunneled service flow, providing identifications of components of the tunneled service flow to the first peer node;
• upon receiving a message containing identifications of the tunneled service flows provided by the first peer node at the domain master,
• granting, by the domain master, to the first peer node, to the second peer node and to the one or more relay nodes, bandwidth resources that are sufficient to support the tunneled service flow.
