摘要： A system for providing, to users of data communication services, access to a communication network providing these services includes an edge node as well as a packet network, such as an Ethernet connecting the users to the edge node. The packet network is equipped with operation and maintenance procedures for preserving edge connectivity over the packet network. The edge node is associated with a backup edge node, which also provides access to the communication network. Preferably, the backup edge node has the same address as the edge node such that, in the presence of failure of the edge node, seamless connection is established between the users and the backup edge node by applying the operation and maintenance procedures.

摘要： A system for the time-based accounting of access by users to services provided by a data network includes a primary access node to provide access by users by establishing via the primary access node a steady connectivity between the users and the network. A secondary access node is associated with the primary access node, such secondary access node being configured for acting as a backup node to maintain connectivity in the case of failure involving the primary access node. The primary access node is configured for issuing a request for credentials for any user requesting access to said data network and, as a result of receiving valid credentials from the user, starts time-based accounting for the user. An authentication node cooperative with the primary access node and the secondary access node stores the secondary access node information items concerning the time-based accounting started for the user. The time-based accounting is thus maintained in the case of failure involving the primary access node as connectivity is maintained by the secondary access node.

摘要： A basic element for the interconnection network of a fast packet switching node, where a synchronization is made at bit input stream level, the cell beginning is identified and a stream conversion from the serial form to a word parallel form is performed. Cells are thus transformed in a completely parallel form and in the same form they are cyclically discharged in the subsequent cell time in a memory, where cells are written and read in a shared way on the basis of instructions given by a control unit, thus performing the switching function. The control unit is essentially based on the use of a content-addressed associative memory, where a fraction of the routing header and a code indicating the time sequence on which the cells are stored. Memory outgoing cells are reconverted from a completely parallel form to a form having the length of one word and therefore in a completely serial form at a bitrate equal to the input one.

摘要： A method of providing access of a mobile terminal to an IP network includes establishing a security association between the mobile terminal and a first security gateway of a first router in said plurality of routers. The mobile terminal is provided access to the IP network via the first router, and the data exchanged between the mobile terminal and the first router is encapsulated by using the security association. The security association is made available to at least one second router having a second security gateway. The mobile terminal is provided access to the IP network via said the second router, and data exchanged between the mobile terminal and the second router is encapsulated by using the same security association. Establishing the security association includes assigning a Security Parameter Index that identifies univocally the first security gateway and the security association. Making the security association available to the second router includes making available to the second router the Security Parameter Index. The second router may thus have access to the security association either by requesting it from the first router or by identifying it in a set of security associations sent from the first router to a set of routers candidate to become the second router as result of the mobility of the mobile terminal.

摘要： A flow of ATM cells to be cross-connected performs two consecutive passes through the connection network (PX) of a node. In the first pass the virtual channels of the input virtual paths (A, B, C) are distributed among intermediate virtual channel bundles (A' . . . C"') each with an overall peak bandwidth equal to that of the virtual path of origin of its contributing channels; between the first and the second pass, the virtual channels are cross-connected and the related cells are temporarily memorized, and at the same time the cell flow to be associated to an output virtual path is shaped; and in the second pass the virtual paths are cross-connected, Temporary memorization and shaping are accomplished in a device (SMS) connected between the outputs and the inputs of the connection network (PX) of the node.

摘要： The switching element for self-routing multistage packet-switching interconnection networks comprises: an input unit, composed of as many sections (IMA, IMB) as the element inputs are, each section comprising a FIFO memory (FIFA, FIFB) for packet buffering; a switch (SW) associated with a control unit (SCU) which, for each packet to be forwarded, sets up the connection requested for that packet between one input and one or more outputs of the element (ECP), on the ground of a routing tag associated with each packet and comprising a first and a second portion relative to normal routing and to broadcasting in the different stages of the network (RC), and solves possible routing conflicts between packets simultaneously arriving at different inputs; and an output unit, composed of as many sections (RU0, RU1) as the element outputs are and performing the whole of the functions necessary for the correct packet forwarding towards a destination. The control unit (SCU) of the switch (SW) is arranged to handle broadcasting of a packet independently of all other elements (EDP) in the same stage, so as to allow broadcasting also to a number of destinations different from a power of 2 (for an element with two inputs and two outputs) and cooperates with the memory (FIF) storing the packet to be broadcast in such a way that broadcasting does not give rise to internal blocking in the network (RC). Said control unit (SCU) moreover solves routing conflicts so as to set an upper bound to packet permanence time within the network (FIG. 2).

摘要： A method for enabling sharing of content files among nodes of a P2P network is provided. The P2P network comprises sub-networks each including a respective plurality of nodes capable of storing content files. Each sub-network has an associated corresponding hash table for indexing the content files stored in the nodes of the sub-network. The hash table is distributed among at least some of the nodes of the sub-network. The method comprises, for each content file stored in at least one node of a sub-network, storing in the hash table associated with the sub-network a criticality index providing an indication of the degree of sharing of the content file among the nodes of the sub-network. The method causes a node to cache at least one content file for sharing with other nodes of the sub-network based on the criticality index of the at least one content file.

摘要： A method for reducing fault detection time in a network includes routers configured to exchange messages via at least one switch to check mutual reachability, each message including a list of routers reachable from the sending router. The method includes snooping, by the switch, a message from a router to extract the list of routers reachable from the router; and, when a network fault occurs that prevents the router from being reachable via the switch, sending, by the switch and to all the other routers connected to the switch, a network fault message including an empty list of routers, so that the receiving routers, not seeing their own identifier in the list, declare the adjacency with the sending router closed, and proceed to reroute traffic on a new route.
