Method for managing service bindings over an access domain and nodes therefor
First Claim
1. A method for managing service bindings over an access domain, the method comprising steps of:
- upon receipt of a service request related message at an access edge node for a first device of a user domain, the service request related message identifying the first device of the user domain and a service provider domain, creating a service binding at the access edge node, the service binding ruling data traffic between the first device of the user domain and the service provider domain by committing an access node serving the user domain and the access edge node in managing of data traffic therebetween over the access domain;
informing the access node serving the user domain for which the service request related message is received of the created service binding; and
enforcing the created service binding at the access node and the access edge node for data traffic over the access domain between the first device of the user domain and the service provider domain.

Abstract
The present invention relates to a method and nodes for managing service bindings over an access domain. For doing so, an access edge node is introduced in the access domain between a plurality of service providers and user domains, and an access node is introduced between the user domains and the access domain. The access edge node creates, modifies and removes service bindings and informs the access node of those creations, modifications and removals. Each service binding binds one of the user domain, the access node and the access edge node on data traffic handling over the access domain between the user domain and the service provider domain. More particularly, the service binding associates the user domain to a Virtual Local Area Network (VLAN) for the service provider domain on the access domain, controlled by the access edge node.

7. An access edge node for managing service bindings over an access domain, the access edge node being located in the access domain between user domains and service provider domains, the access edge node comprising:
-
an input/output unit for receiving a service request related message for a first device of a user domain for a service provider domain;
a service agent unit for creating a service binding, the service binding ruling data traffic between the first device of the user domain and the service provider domain over the access domain, the service binding committing an access node serving the user domain and the access edge node representing the service provider domain in handling of data traffic therebetween over the access domain; and
a controlling unit for informing the access node serving the user domain for which the service request related message is received of the creation of the service binding through the input/output unit, and for enforcing the created service binding at the access edge node for data traffic between the first device of the user domain and the service provider domain over the access domain. - View Dependent Claims (8, 9, 10, 11)

12. An access node for managing service bindings over an access domain, the access node being located between user domains and the access domain, the access node comprising:
-
an input/output unit for forwarding data traffic from user domains over the access domain and for receiving service binding related messages;
an aggregation unit for storing service bindings and for enforcing the stored service bindings; and
a controlling unit for controlling data traffic and for managing service bindings, the controlling unit evaluating the service bindings related messages received at the input/output unit and updating the stored service bindings accordingly, and controlling the data traffic from the user domains over the access domain in accordance with the stored service bindings. - View Dependent Claims (13, 14)
