Abstract:
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.
Abstract:
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.
Abstract:
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.
Abstract:
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.
Abstract:
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.
Abstract:
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.
Abstract:
The harvester for picking up berries comprises a frame adapted to be driven in a field of berries, a comb mounted between opposite sides of the frame and comprising a plurality of teeth extending substantially in a horizontal position to seize branches of berries as the frame is driven in the field. The harvester is provided with a sweeping system mounted on the frame above the comb for sweeping the berries of the branches seized by the comb. The sweeping system preferably comprises a brush parallel to the comb and comprising a rotatable shaft operatively mounted between the opposite sides of the frame and a plurality of bristles circumferencially distributed around the shaft.
Abstract:
A method for moving application related records (220) between distributed cloud domains (206a to 206w) when a user terminal (210) changes its physical location and a predetermined condition is fulfilled. The user terminal (210) is connected to a telecommunication network (201) and uses an application (App). The method determines that a user terminal location has changed at least from a first network area (202) of the telecommunication network (201) to a second network area (204), considering one or more constraints associated with (i) a location of the user terminal (210) in the second network area (204), (ii) a location of a cloud component of the application (App) in a first cloud domain (206n) associated with the first network area (201), and (iii) a location of a second cloud domain (206w) associated with the second network area (204), and moves, when the predetermined condition is fulfilled, the application related records (220) from the first cloud domain (206n) to the second cloud domain (206w).
Abstract:
In a provider backbone—traffic engineering network, a method and a bridge node are provided for setting up path between edge bridges connected to customer premises. A first edge bridge advertises towards peer edge bridges a tuple comprising a port identity and a layer two address. When it needs to set up a path towards the first edge bridge, one of the peer edge bridges uses information in the tuple to compute a path label.
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.
