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： The present invention relates to network nodes and methods that use an encoding scheme for encoding a point-to-multipoint traffic path from one ingress node to a plurality of egress nodes in, for example, a Multi-Protocol Label Switching network. According to the encoding scheme a so-called common ERO is used. The common ERO specifies a list consisting of nodes that are common to several sub paths in order to provide a compression mechanism that reduces the size of path messages that are used for signaling the point-to-multipoint traffic path.

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： Problems caused by Internet Protocol datagram fragmentation are solved by creating a session context for the datagram fragments without actually reassembling the datagram from its fragments. The session context enables treatment of the datagram without actually reassembling it. Processing fragments can be followed by forwarding the processed fragments to another node that can further fragment the IP datagram.

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： A system and method for virtualizing a flow switch to be used by application providers in a cloud computing environment is provided. An application provider's packet handling rules are received by a cloud management system. The rules are translated from the application provider's overlay topology to the underlay data center topology. The underlay network elements involved in the received rules can be identified. A translated rule can be decomposed into a plurality of rule portions which are transmitted to the appropriate underlay network elements.

摘要： The present invention relates to an ingress node (102, 700) and methods therein for Operation Administration arid Maintenance, OAM related to Resource Reservation Protocol-Traffic Engineering, RSVP-TE5 for obtaining attributes for timer values being assigned to a connection from the ingress node (102) via intermediate nodes (104, 106, 108, 110) to an egress node (112), during configuration of die connection. An interval of suitable tinier values for the intermediate nodes is specified. Configuration attributes are obtained for a timer value within an interval that is acceptable by the intermediate nodes and the egress node, based on the specified interval of suitable timer values. The obtained configuration attributes are applied during configuration of the connection from the ingress node via the intermediate nodes to the egress node, if the obtained configuration attributes are appropriate to the ingress node. Fine-tuning of connection related timers can therefore be achieved, decreasing the overall recovery time and the overall overhead.

摘要： A packet node and corresponding methods are provided for providing services to packets received at the packet node. At an ingress card, a packet is classified and a virtual media access control (VMAC) address is attached to the packet. The VMAC address identifies a service component for providing a service to the packet. Layer two switching of the packet is made within the packet node, based on the VMAC address. After processing of the packet by the service component, a new VMAC address is attached to the packet. Further layer two switching of the packet, based on the new VMAC address, may lead to further processing by another service component or to forwarding of the packet beyond the packet node.
