Patent number: 8077619Abstract: A method and nodes for aggregating data traffic over an access domain between service providers and user domains. An access edge node is introduced in the access domain between service providers and user domains. The access edge node hosts service agents, each service agent controlling a Virtual Local Area Network (VLAN) over the access domain for one of the service providers. The access edge node verifies whether a service agent, corresponding to the service provider identified in a received service request, exists. If so, the user domain is added to the VLAN corresponding to the requested service provider by creating a service binding at the access edge node. An access node providing access to the access domain to the user domain is informed of the service binding. Data traffic between the user domain and the identified service provider is aggregated over the access domain according to the created service binding.Type: GrantFiled: December 27, 2005Date of Patent: December 13, 2011Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Sylvain Monette, Mathieu Giguere, Martin Julien, Benoit Tremblay

Patent number: 7881198Abstract: 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.Type: GrantFiled: December 27, 2005Date of Patent: February 1, 2011Assignee: Telefonaktiebolaget L M Ericsson (PUBL)Inventors: Sylvain Monette, Mathieu Giguere, Martin Julien, Benoit Tremblay, Joacim Halén

Patent number: 7801039Abstract: 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 an access 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, and identifies 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.Type: GrantFiled: February 14, 2006Date of Patent: September 21, 2010Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Sylvain Monette, Mathieu Giguere, Martin Julien, Benoit Tremblay

Patent number: 7792996Abstract: The present invention relates to a method and nodes for handling multicast messages over an access domain. The method starts with the receipt of a multicast message from a service provider domain. The method pursues with the identification of a service agent corresponding to the service provider domain from which the multicast message is received. Then, the content of a Virtual Local Area Network (VLAN) Tag field of the multicast message is modified so as to correspond to the identified service agent. The modified multicast message is forwarded on the access domain. Upon receipt of the modified multicast message at an access node, the access node identifies at least one service binding related to the service agent identified in the VLAN Tag field of the received multicast message.Type: GrantFiled: February 14, 2006Date of Patent: September 7, 2010Assignee: Telefonaktiebolaget L M EricssonInventors: Sylvain Monette, Mathieu Giguere, Martin Julien, Benoit Tremblay

Patent number: 7765312Abstract: A method and an access domain node identify and manage a type of service offered by a service provider to user domains. A service template is prepared by the service provider, comprising an address of a server and a protocol identifier, as well as policies for controlling traffic for the service. Upon set up of a connection between a user domain and the service provider, an address of the user domain is added to the service template to produce a service flow management set. Every data packet exchanged between the user domain and the server, in either direction, is related to a service data flow for a given service type by checking for a match between a source address, a destination address, and a protocol type contained therein, with an appropriate service type. Policies from the service flow management set are used to manage the flow of data packets.Type: GrantFiled: March 12, 2007Date of Patent: July 27, 2010Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Sylvain Monette, Martin Julien, Benoit Tremblay

Patent number: 7706265Abstract: The present invention relates to a method, an access node, an access edge node and a decentralized node for aggregating data traffic over an access domain. The decentralized node corresponds to one of the service providers, and is located in closer proximity with user domains to be serviced. The decentralized node maintains over the access domain one or several Virtual Local Area Networks, for aggregating thereon data traffic to be exchanged with the user domains, on behalf of the service provider domain. To allow proper aggregation of the data traffic, service bindings are created and stored at the access edge node, and further stored at the decentralized node and at the access node. Therefore, aggregation of the data traffic between the decentralized node and the user domains over the access domain is performed in accordance with the created service bindings.Type: GrantFiled: October 30, 2006Date of Patent: April 27, 2010Assignee: Telefonaktiebolaget L M Ericsson (PUBL)Inventors: Sylvain Monette, Mathieu Giguere, Martin Julien, Benoit Tremblay

Publication number: 20090097492Abstract: Several services offered by distinct service providers can be accessed from a single user device, through one or more gateways. To ensure quality of service control, each service provider allocates a distinct address to the user device. Distinct forwarding information bases and service mappings are defined at the user device, comprising one such forwarding information base for each service provider and one service mapping for each service type offered by a given service provider. The separate addresses allocated to the user device are related to the separate service mappings. Distinct virtual local area networks (VLANs) are defined, each containing one of the forwarding information base and one of the service mappings. Tags added to packets by the gateways and arriving at the user device are used to link the packets to the proper service provider and to the proper service type.Type: ApplicationFiled: October 12, 2007Publication date: April 16, 2009Applicant: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Sylvain Monette, Mathieu Giguere, Martin Julien, Benoit Tremblay
