摘要： Methods and apparatus, including computer program products, implement techniques for processing data packets in a computer network. A packet filter engine (230) is configured to process data packets at wire-speed based on or more user defined packet policies. A received data packet is examined to determine if there is a match between the data packet and one or more packet policies. If no matching packet policies are found, the packet is routed. If a matching packet policy is found, the data packet is processed based on the policy action fields of the matching policy.

摘要： A multi-service transport apparatus (switch) for integrated transport networks is described. The apparatus comprises an electrical matrix, termination function means handling signals incoming at said apparatus input, a plurality of termination function means interfacing different layers, and adaptation function means. The termination function means handling incoming signals are implemented in input/output port devices; the termination function means interfacing different layers and said adaptation function means are implemented in adapter devices. According to the present invention, the matrix performs exclusively the switching of the incoming signals that are already terminated and adapted by said input/output port devices and by said adapter devices and it is transparent with respect to the signal format.

摘要： In a telecommunication system wherein both a first layer charging function and a second layer charging function are able to attend to the processing of the charging data of the first layer, there is a risk of the first layer charging being charged twice. To ensure that a client is not unnecessarily charged twice for a first layer service, and to ensure that the first layer service will be charged for, the function controlling the second layer charging transmits, to the function controlling the first layer charging function, information (303) indicating whether the second layer charging function attends to the charging of both layers, and if so, double charging is prevented.

摘要： A system and method for sending and receiving information in a network using a redundant switching architecture. In one embodiment, the method includes generating a communications frame including a first header at a first control element. The first header is mapped to a second header and then the communications frame is encapsulated with a set of two redundant destination addresses whereby two instances of the communications frame are created. The communications frame instances, including the second header and the redundant destination addresses, are sent from the first control element via both a first switching plane and a second switching plane to a second control element. Upon receipt, only one of the communications frame instances is retained by the second control element for upstream processing.

摘要： A local access fiber optical distribution network is disclosed in which a dedicated pair of diversely routed optical fibers is routed in the distribution network for each customer. In a preferred embodiment, a dual physical overlay ring core topology is used in the core. The distribution network includes working and protection logical path connectivity. No 802.1D Spanning Tree is required for recovery, providing resilience to any single network failure in any device or link, quick recovery times from failure, and a failure detection/recovery protocol that is not active on any devices other than the devices directly attached to the subscriber.

摘要： A switch includes a backplane and multiple packet processors. One or more packet processors include multi-level policing logic. The packet processor receives a packet and classifies the packet into multiple policeable groups. The packet is compared against bandwidth contracts defined for the policeable groups. Nested lookups are performed for the packet in a policing database to identify the multiple groups and to retrieve policing data for the multiple policeable groups. The policing results, which may be combined into a single policing result by taking the worst case policing result, are applied to disposition logic as recommendations, and are combined with other disposition recommendations to make a disposition decision for the packet.

摘要： Multiple lookup engines stacked upon one another in a single data communication switch. The lookup engine at the top of the stack transmits its result to the neighboring downstream lookup engine which either validates and transmits the received result or its own result based on the quality of its match. The result preferably indicates an exact match, partial match, or no match. Although several lookup engines can return a partial match, an exact match preferably occurs in only one lookup engine. The comparison, validation, and transmission steps are repeated by each downstream lookup engine, with the lookup engine at the bottom of the stack validating and returning a final result to the packet processor. The returned final result reflects a search result with the highest match quality.

摘要： A high availability packet forwarding router (102) for an internet protocol (IP) network, includes two control processors (104,106), one or more service termination cards (STCs)(112) with forwarding information bases (FIBs)(108,110), and a packet forwarding engine (214). The two processors run asynchronously in a master/standby relationship. Integrity of processes running on the control processors is monitored and the forwarding engine forwards packets according to a FIB maintained by an in-service one of the control processors. Hitless failover and hitless software upgrades are supported.

摘要： A router device and a frame transfer method capable of attaching a virtual identifier necessary for the datalink layer switching that improves a transfer efficiency at the router device. The router device receives a frame having a datalink flow identifier for identifying a flow of a packet corresponding to the frame on a datalink layer, which is contained in a prescribed region of the frame corresponding to an upper layer protocol identification information region of a frame format for frames to be transferred via a network layer processing, and transfers the frame received from a previous hop node to the next hop node by obtaining the address information of the next hop node by referring to the memory unit using at least the datalink flow identifier contained in a prescribed region of the frame as a key, and by attaching the address information of the next hop node to the frame, without carrying out the network layer processing, where the memory unit stores a correspondence of the datalink flow identifier and an address information of the next hop node.
