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： A router comprising a plurality of elements, each having an element identifier, subdivided into a plurality of groups of at least one element. Each group has a common identifier and each member within each group shares redundant capabilities. Each element is capable of communicating with another element by addressing information to the common identifier instead of the element identifier. Optionally, one element can be a member of more than one group. Another option suggests that all elements within a group share essential information associated with a service provided by the group. Another option is implemented through one element of the router identifying a primary element for a group, wherein the primary element serves requests addressed the corresponding common identifier. Yet another option suggests that one element is identified through configuration of the router as a primary element in its group to serve requests addressed to the common identifier.

摘要： 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. The method also provides an access node and an access edge node for performing the invention.

摘要： A method and a related router comprising a network interface, a logical addressing module and a forwarding element card. The logical addressing module is capable of maintaining at least one local table associating at least one card of the router with at least a portion of at least one service provided by the router. The forwarding element card is capable of receiving a packet stream on the network interface, detecting that the packet stream requires further treatment from a further card of the router and, upon detection, consulting the local table to find an identifier, to which the further card is linked, based on information found in the packet stream before forwarding the packet stream toward the further card.

摘要： 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.

摘要： A router, a switching element card and a related method for providing a rate limiting mechanism in the router comprising a network interface, a forwarding element card connected to the network interface and the switching element card. The switching element card is capable of receiving the network traffic from the forwarding element card and applying a rate limiting mechanism on the network traffic before forwarding the network traffic to a further card of the router. The switching element card does so if the further card has a lower treatment rate than the forwarding element card and the rate limiting mechanism is applied based on the difference between the rate of the received network traffic and the treatment rate of the further card.

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.

摘要： A finite state machine and a router adapted thereto for providing a service. The finite state machine is executed on a first and a second distinct hardware modules. The first module has access to a first memory and the second module has access to a second memory. The first and second memory are different and not shared therebetween. At least one transition between a first state and a second state of the finite state machine from the first module to the second module is performed by sending local information of the first module toward the second module. The local information at least indicates the second state of the finite state machine. Local information can be inserted by the router, for example, in a meta-data header.
