A node includes a deterministic path that conveys packets from input ports to output ports via a deterministic switch. The node also includes a statistical path that conveys packets from the input ports to the output ports via a statistical switch. A deterministic scheduler selectively enables the first path or the second path based on traffic properties that indicate whether the packets are in a stochastic flow or a deterministic flow. In some cases, the deterministic scheduler includes timing circuitry that determines an arrival time of a packet at an input port of a node and enabling circuitry that generates signaling that selectively enables a first path for conveying the packet via a deterministic switch or a second path for conveying the packet via a statistical switch. The selection is based on whether the arrival time indicates that the packet is in a stochastic flow or a deterministic flow.

Electronic packet switching based on traffic properties

A node is deployed along a path between a master device and a slave device. In some cases, the path includes additional nodes. The node includes a plurality of queues configured to be associated with a corresponding plurality of flows. A first queue of the plurality of queues is configured to be associated with a first flow that conveys timing messages for synchronizing the master device and the slave device. A scheduler is configured to schedule messages from the first queue during an extended time window that encompasses expected arrival times of a first set of timing messages in the first flow. The node reverts to normal behavior in response to completing processing of the first set of timing messages. During normal operation, the node schedules messages from the first queue during a default time window that is shorter than the extended time window.

Coordinated timing syncronization and time-aware shaping

The invention concerns a method for enhancing the handover of a mobile station (-) from a serving base station () of a cellular network to a new base station, the new base station is selected among a neighbor list including neighboring base stations, the radio coverage cell (r-r) of which overlaps the radio coverage cell (r) of said serving base station (). It is also provided the base station for carrying out the method. According to the invention it is determined a current sector (s-s; s-s) in which said mobile station (-) is located among a plurality of sectors (s-s; s-s) partitioning the radio coverage cell (r) of said serving base station (), and the neighbor list includes only the neighboring base stations the radio coverage cell (r-r) of which overlaps said current sector (s-s; s-s).

A method for scanning in a wireless networkcomprises determining attributes for an on-going service of a mobile station, MSand allocating scanning intervals for the MS depending on the determined attributes. The attributes for the ongoing service may include at least one of: type of service; and quality of service requirements. In one method, scanning intervals for the MS are allocated by a base stationalso depending on the size of the neighbor cell list. The wireless network may, for example, be a WiMAX network.

A method for reserving resources in a packet communication network, preferably an IP protocol network. The method includes sending an active packet containing a request for reservation of resources for an active data flow, receiving the packet by an active node in the network, and reserving resources of the node according to the request. In this method, an active packet communication network node, in particular an IP active router, reserves resources for processing data of an active data flow according to a resource reservation request for this active data flow contained in this active packet received by the node.

The invention relates to an inter-domain router, for an Internet Protocol communications network, including a processing module to generate as a function of routing data outgoing messages intended for other routers which comprise information data representative of routes for routing IP datagrams and a control module to analyze at least some of the routing data, in order to define route aggregates as a function of selected configuration information, and for delivering output data representative of the route aggregates, so that the processing module can generate outgoing messages including information data representative of the route aggregates.

An access control gateway (E) for controlling access to a first data network (D), which gateway includes a filter for filtering data coming from a second data network. The filter is adapted to decide whether to transmit the data to the first network as a function of information contained in the data relating to the processing of the data by active routing systems of the first network.

A device for processing routing protocol messages for a router of an Internet protocol communication network comprises a processor that determines if routing information contained in a routing protocol message to be sent to at least one destination peer router has been checked at least once by at least one routing checking tool, and the result of each check. It adds to the routing protocol message status information representing at least the result of each check effected on the message, with a view to sending it to the destination peer router.

We describe an active node, which receives an active message containing an active application identifier, transmits the active application identifier to an active applications server. receives associated code from the active applications server, and executes the associated code. The active node also may transmit to the active applications server information relating to its own environment, and information relating to whether it is an edge node or core node in the network, enabling the active applications server to determine the associated code to return to the active node.

A routing information management device for a router of a communication network comprises a first routing information base fed with routing information contained in routing protocol messages, a second forwarding information base having a maximum number of entries, and management means that compare at selected times the number of entries in the first routing information base relating to sending to a selected threshold less than or equal to the maximum number of entries in the second forwarding information base so as to feed the second forwarding information base with routing information selected as a function of the result of the comparison.

Device for use in a communication network router to select routing information

The request for the response from the sender to the receiver is dynamically routed via a first route traversing the network nodes. Addresses of the traversed network nodes are recorded in an order of traversing in the request. A second route is determined based on the recorded addresses of the nodes. A supplemental packet is generated. The supplemental packet is transmitted to the sender of the request via the determined second route, from a node address to a node address. The response is dynamically routed to the sender of the request by reversely traversing the first route.

A distributed, multistage agent for monitoring, diagnosis and maintenance of network devices comprises an input/output interface for receiving input monitoring and diagnostic data relevant to operation of a first neighboring agent and transmitting output monitoring and diagnostic data relevant to operation of the host network device to a second neighboring agent. An agent process analyzes the input data and generates processed data characterizing operation of the host network device, using a local database which stores expected performance data on operation of said network device. The processed data is correlated with the expected data any error is signaled to the network operator. The agents may be designed as a multiple stage process, the stages being triggered by the data output by an earlier stage only when needed.
