    摘要： A network node of a telecommunications network controlled by a link-state protocol includes a network interface which receives a message that contains information on a change in topology of the network. The node includes a processing unit that blocks forwarding of traffic to at least one neighbor node of the network at the network interface, agrees on the change in topology with the neighbor node; and unblocks the forwarding of traffic when the neighbor node has information about the topology which is the same as the information about the topology in a memory. A transient loop prevention method of a network node of a network having a plurality of a network nodes controlled by a link-state protocol includes the steps of receiving a message at a network interface which contains information on a change in topology of the network. There is the step of blocking forwarding of traffic to each neighbor node of the network at the network interface by a processing unit. There is the step of agreeing by the processing unit on the change in topology with the neighbor node. There is the step of unblocking the forwarding of traffic when the neighbor node has information about the topology which is the same as the information about the topology stored in a memory.

    摘要： A method for transmitting data files in a network includes receiving requests from destination devices for packets of the data files. The method includes constructing a conflict graph such that (i) each packet requested by each destination device is represented by a distinct vertex in a plurality of vertices of the conflict graph, (ii) the plurality of vertices are associated with the destination devices, and (iii) links are created between the plurality of vertices based on which of the plurality of vertices represent a same requested packet and which requested packets are stored in caches belonging to destination devices. The method includes assigning the plurality of vertices to groups based on the links. The method includes coloring the plurality of vertices based on the assigning. The method includes combining the packets represented by vertices having a same color. The method includes sending the combined packets.

    摘要： A method for routing data at a first node of a network including a second node. The method includes: providing the first node with a database storing an association between: an URL component identifying content at the first node, and a unique identifier associated to the second node, the unique identifier being specified by the second node; registering content locally stored in the second node by storing in the database an association between an URL component identifying the locally stored content and the unique identifier of the second node; and, upon reception from a requesting entity, by the first node, of a content request having a content identifier, the method includes: checking in the database whether the content identifier includes the URL component, and forwarding the content request to the second node if the content identifier includes the URL component associated with the unique identifier of the second node.
