摘要： 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. For each related service binding, the access node adapts the VLAN Tag field of the multicast message so as to correspond to a local VLAN information, and forwards the adapted multicast message on a user port corresponding to the service binding. The invention also includes an access edge node and an access node adapted to perform the method of the present invention.

摘要： The present invention relates to a method and nodes for handling broadcast messages over an access domain. For doing so, an access node and an access edge node are adapted to allow tunnelling of broadcast messages within Unicast messages transmitted over the access domain. The access node receives broadcast messages from user domains, intercepts the broadcast messages and forwards the received broadcast messages to the access edge node in Unicast messages. The access edge node receives and identifies the tunnelled broadcast messages. Then, the identified tunnelled broadcast messages are detunneled by the broadcast handler at the access edge node and handled by the broadcast handler.

摘要： A method, a router and a switching element card for providing a rate limiting mechanism in the router. Upon reception of a packet stream from a forwarding element card of the router at a first rate, it is determined that the packet stream is to be forwarded to a further card of the router. If the further card has a treatment rate lower than the first rate, the packet stream is passed to a rate limiting mechanism before being forwarded to the further card. Optionally, if the further card does not have a treatment rate lower than the first rate the packet stream is forwarded to the further card without being passed to the rate limiting mechanism.

摘要： 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.

摘要： 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.

摘要： The present invention provides a method and nodes for authenticating nomadic users accessing service providers. An access edge node authenticates nomadic users when service requests are received therefrom. The access edge node hosts a plurality of service agents, where each service agent comprises transport parameters for access to one of the service providers. Upon receipt at the access edge node of a service request message identifying a service provider and a nomadic user, an identity of the nomadic user is authenticated and verification is made that a service agent corresponding to the identified service provider exists. If both the authentication and the verification are positive, an authenticated service binding is created, connecting the nomadic user, the service provider and the transport parameters. Then, an access node providing access to the nomadic user for which the service request message was received is informed of the authenticated service binding.

摘要： 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.

摘要： The present invention relates to a method and nodes for performing data traffic aggregation over an access domain using service bindings. 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 one of the service provider domains, a service binding is created at the access edge node. The service binding rules 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 a manner of managing data traffic therebetween over the access domain. An access node serving the user domain for which the service request related message is received is informed of the created service binding. The created service binding is enforced 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 by removing a user device MAC address from Unicast messages exchanged therebetween over the access domain and replacing with a virtual MAC address recognized by the access node and the access edge node.
