Method and nodes for aggregating data traffic through unicast messages over an access domain using service bindings

METHOD, ACCESS EDGE Nà AND ACCESS TO PERFORM DATA TRAFFIC AGREGAÇçO THROUGH AN ACCESS USING DOMAIN SERVICE LINKS. The present invention relates to a method and nodes for performing data traffic aggregation over an access domain using service bindings. On receipt of a related service request in an access edge node for a first device of a user domain message, the message regarding the service request identifying the first user domain of the device and one of the service provider domains a service connection is created in the access edge node. The service connection governs data traffic between the first user domain of the device and the service provider domain committing an access node serving the user domain and the access edge node in a way to manage data traffic between them through the access domain. One serving the user domain access node to which the message regarding the service request is received it is informed of the service connection created. The service connection set up is required on the access node and for data traffic access edge node through the access domain between the first user domain of the device and the service provider domain removing a MAC address device unicast message user exchanged between them through the access domain and replacing with a virtual MAC address recognized by the access node and the access edge node.
