  • Publication number: 20210400425
    Abstract: A method for delivering to a user a dedicated service restricted to a predefined service area includes, performing an access request to a dedicated service. The dedicated service is delivered from a server through a data network between a user device and the server. The method also includes determining a service profile associated with the user, and assigning to the user device a dedicated communication channel for the dedicated service. The method further includes starting a communication session with the server through the data network according to the assigned dedicated communication channel, and performing an authentication request to the server. If the service authenticates the user successfully, the position of the user is obtained, and the dedicated service is delivered to the user device.

  • Publication number: 20200245191
    Abstract: A method for distributing packets of a data traffic over aggregated radio links connecting a node of a packet-switched wireless communication network to a further node of the packet-switched wireless communication network includes, at an indoor unit of the node, configuring at least one set of distribution rules indicating, for each of a first radio link and a second radio link of the aggregated radio links, an association between the radio link and a subset of values of a priority parameter carried within the packets. The method also includes, upon reception of a packet of the data traffic, distributing the packet over the first radio link or the second radio link on the basis of the priority parameter value carried within the packet and the associations.

  • Publication number: 20190268274
    Abstract: A method for controlling a bandwidth over a communication link connecting first and second client network elements. The first element is configured to send to the second element data traffic including at least a best effort traffic flow of packets. The method includes: at the first element, marking a number of best effort packets with a control code, the control code taking values within a predetermined ordered control sequence of values, and sending the marked packets to the second element through the link; at the second element, checking the control code of each marked best effort packet and, in case of detection of a missing value of the control code, sending to the first element a packet containing a feedback code indicative of an adjustment of the bandwidth; and, at the first element, upon reception of the feedback code, adjusting the bandwidth.

  • Patent number: 8588076
    Abstract: 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.

  • Patent number: 8553534
    Abstract: Delivering multicast data traffic over a communication network includes a first network node delivering multicast data traffic to second network nodes. The first and second network nodes are connected by a transmission network in a ring architecture and implement a point-to-multipoint layer 2 protocol. A method includes at the first network node: collecting alarms signals indicative of a failure along the whole ring and of the second network nodes. Based on a current state of the alarm signals, delivering the multicast data traffic either in a first delivery direction along the ring, or in a second delivery direction along the ring opposite to the first delivery direction, or in both the first and second delivery directions. At each of the second network nodes: collecting alarm signals indicative of a failure of the transmission network locally to the second network node and of the second network node.

  • Patent number: 7746767
    Abstract: Extra traffic paths are provided in a communication network including at least two protection channels associated to respective transmission channels. Each protection channel admits an active state for carrying, in the presence of a failure in the associated transmission channel, traffic to be carried by the associated transmission channel, and a stand-by state, wherein the protection channel is adapted to carry extra traffic. The protection channels are run in a sub-network connection protection scheme, whereby one of the protection channels in its stand-by state is adapted to ensure recovery of extra traffic carried by the other protection channel while the other protection channel is switched to its active state or is subject to failure.

The packet network is equipped with operation and maintenance procedures for preserving edge connectivity over the packet network. The edge node has associated therewith a backup edge node providing access to the communication network. Preferably, the backup edge node is reachable by the users via the packet network by using an address common to the edge node and the backup edge node associated therewith. In the presence of failure of the edge node, connection is established between the users and the backup edge node by applying the operation and maintenance procedures. Preferably, this, occurs by using the address common to the edge node and the associated backup edge node.

  • Patent number: 7561532
    Abstract: A method of designing a transport network having a plurality of network elements and a plurality of connections between the network elements by (a) defining a first network configuration and at least one alternative network configuration for the same transport network; (b) calculating for each network configuration, a probability function representing, for each maximum number of routable flows, the probability of routing such a number of flows in the network configuration currently considered; (c) calculating for each network configuration, a unit-cost-per-flow function calculated as the ratio between a sum of the costs relative to the network elements of the network configuration currently considered and the probability function; and (d) comparing the unit-cost-per-flow functions of the network configurations considered, for choosing a network configuration having a lowest unit-cost-per-flow value.

  • Patent number: 7349341
    Abstract: A procedure for sorting a plurality of circuit data flows (7, 8, . . . ) located, according to an initial configuration, in a plurality of sets of slots (space, time, frequency or wavelength) in a transport sub-network, comprising the following steps:—calculating a theoretical configuration in which flows are optimised in terms of occupied band by applying a theoretical flow routing algorithm; on the basis of the theoretical configuration defined above, exchanging the position of the flows in the sub-network slots to obtain an optimal arrangement which minimises the occupied slots; flows whose position corresponds to the position assumed by the flows in the initial position are identified to reduce the number of exchanges; defining and implementing a minimum shift sequence of single flows needed to shift each single flow from an initial position occupied in the initial flow configuration to a final position corresponding to the position assumed by the flow in the optimal slot set arrangement.
