摘要： A method and apparatus for transmitting data using moving communication nodes. A network element can communicate with a plurality of moving communication simultaneously. The network element identifies a plurality of potential initial nodes for transmitting data to a desired destination. The network element can then evaluate each of the potential initial nodes using one or more selection criteria. The initial node can be selected from the plurality of potential initial nodes as the potential initial node that best satisfies the selection criteria. The transmission to the initial node can act as the first link in a data route from the network element to the desired geographic destination.

摘要： A method of and a node device for relaying a message in a network of operatively interconnected node devices arranged along at least one elongated geographic track is disclosed. Each node device is provisioned with a unique network address associated with a geographic location of the node device in the network. The method comprising the steps of: receiving, by a relay node device having a relay network address, a message originated from a source node device having a source network address and destined to a destination node device having a destination network address; determining, by the relay node device, to relay the received message, based on a relationship between the relay network address, the source network address and the destination network address, and relaying, by the relay node device, the message by retransmitting the received message.

摘要： The present invention relates to a method (100, 200, 300, 400) of communication between nodes in a telecommunications network. In particular, each node maintains a copy of a shared digital ledger, is identified by a respective identification code and implements a software application configured to manage the transmission of data packets and maintain the shared digital ledger. The method (100, 200, 300, 400, 500) comprises that each sending node of a data packet executes the steps of: a. memorizing a list of identification codes, each identification code identifying a respective node comprised in a subset of nodes of the network, b. identifying (103; 200, 500) a receiver node to which to transmit said data packet, c. generating (105) a data packet to be delivered to a recipient node, d. transmitting (107) to the first node of said minimum sequence of nodes the data packet, e. issuing (109) a request to the network nodes to record said data packet transmission in the distributed ledger, and when a data packet is received, the method requires that each receiver node, other than the recipient node of the data packet, repeats at least the steps b., and D.. Advantageously, the step a. of identifying (103, 200; 500) a receiver node to which said data packet is transmitted comprises: - generating (203; 503) a graph database in which a respective arc connects the sender node or the receiver node, different from the recipient node, to each node of the network of which the identification code is comprised in the list of identification codes of the sender node or the receiver node, other than the recipient node, and - selecting (209; 505) the receiver node among the nodes of said graph database. Furthermore, if it is not possible to identify a receiver node, the method further comprises the steps of: - analyzing a contact list stored in the sending node, each contact in the contact list being associated with a corresponding device; - if at least one contact is identified in which is associated with a device having installed said software application but not enabled to exchange packets in the telecommunication network, enabling said device to exchange packets as a temporary node of the telecommunication network, and - selecting said device as receiver node of the data packet.

摘要： Techniques for utilizing Software-Defined Field- Area Network (SD-FAN) controllers to receive a geographic location and transmission power of individual nodes and generate a geographic location topology of a Field-Area Network (FAN) to provide nodes with location- aware route paths for data transmission. One or more SD-FAN controller(s) may maintain a geographic location database to store the geographic location and transmission power of the individual nodes. Each node may utilize a Destination Address Object to advertise its geographic location and transmission power to the SD-FAN controller. The SD-FAN controller(s) may utilize the geographic location table to generate the geographic location topology of the FAN and determine a location-aware route path for optimized data transmission between nodes in the FAN.

摘要： For delivering an audio and/or video content to a mobile terminal, a content delivery system is deployed on top of a mobile network. The content delivery system comprises plural edge cache servers arranged using a star topology or a hierarchical topology. The edge cache servers are connected to respective aggregation nodes of the mobile network such that a configurable breakout function of the aggregation nodes enables routing thereto packets addressed to an anycast addressing associated with the edge cache servers. When receiving a request, from the mobile terminal, for obtaining a manifest file of the audio and/or video content, an edge cache controller of the content delivery system creates a session identifier including a unicast addressing part pointing to the edge cache controller, and redirects the mobile terminal to the anycast addressing of the edge cache servers. The edge cache servers then obtain the session identifier from the mobile terminal and use the unicast addressing contained therein to receive context information from the edge cache controller.
