Method and nodes for performing bridging of data traffic over an access domain

METHOD FOR CARRYING DATA TRAFFIC OF LIGAÇçO THROUGH AN ACCESS AREA, E, ACCESS EDGE Nà AND ACCESS Nà FOR CONNECTING THROUGH DATA TRAFFIC AN ACCESS DOMAIN. The present invention relates to a method and nodes for performing data traffic connection over an access domain. To do so, data traffic received on an access node of a first user domain and destined to a second user domain, the access node identifies a service binding corresponding to the received data. Then the access node enveloping data traffic in a unicast message addressed to an access node edge according to the connection identified service. The enveloped data traffic is then routed to the access edge node. The access edge node receives the enveloped data traffic, and identifies the service connection corresponding to the received data enveloped traffic. The node edge access then proceeds to redirect data traffic enveloped a second access node according to the service connection identified it. Traffic data is received redirected enveloped in a second access node, which is desenvelopado and forwarded to the second domain user. The method also provides an access node and an access edge node to perform the invention.
