Problems solved by technology
[0009] There is currently no known solution to the problems associated with the growth of the number of user equipment and the number of service providers offering the service on IP networks
In addition, no long-term solution has been identified that provides a practical and non-disruptive solution to the incremental data communications of large IP networks serving thousands of user domains

Embodiment Construction
[0041] The novel teachings of the present invention will be described below with reference to different exemplary embodiments. It should be understood, however, that such examples provide only some examples of the advantageous uses of the novel teachings of the present invention. In general, statements in the description of the invention do not limit any claimed aspect of the invention. Furthermore, some statements may apply to some inventive features but not to others. In the figures, similar or identical elements are designated with the same reference numerals throughout the figures.
[0042] The present invention provides methods and nodes for performing data communication bridging over an access domain. As known in the art, an access domain includes a number of switches whose task is to switch data communications to their destinations. Data communications carried over the access domain originate from the user domain and the service provider domain. As the interest in a...

The present invention relates to a method and nodes for performing bridging of data traffic over an access domain. For doing so, for data traffic received at an access node from 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 tunnels the data traffic in a Unicast message addressed to anaccess edge node in accordance with the identified service binding. The tunnelled data traffic is then forwarded to the access edge node. The access edge node receives the tunnelled data traffic, andidentifies the service binding corresponding to the received tunnelled data traffic. The access edge node then proceeds with redirecting the tunnelled data traffic to a second access node in accordance with the identified service binding therein. The redirected tunnelled data traffic is received at a second access node, where it is detunnelled and forwarded to the second user domain. The method also provides an access node and an access edge node for performing the invention.
