A method for network communication, the method including distributing a distributed ledger across a network having a plurality of nodes and maintaining the distributed ledger on each of the plurality of nodes of the network. The method further including initiating a modification to the network, verifying the modification to the network by checking the distributed ledger maintained by each of the plurality of nodes of the network, and permitting the modification to the network when the modification to the network is authorized by the distributed ledger maintained on each of the plurality of nodes in the network.

A method, system and a network element for routing at least one data stream in a telecommunications network, the network having at least one transmitting node providing at least one data stream, at least one receiving node receiving the at least one data stream, and zero or more processing nodes, and at least one link connecting said nodes. All nodes communicate their capabilities to a system database on a database server which receives at least one request with at least one condition for sending at least one data stream between two nodes. For or each request, a measure is calculated for at least one route between said two nodes, and instructions are provided to use only the at least one route having measures compliant with the at least one condition in the request. An optimal route can be determined using at least one heuristic rule or linear programming.

A congestion notification method, a related device, and a system, where the method includes receiving, by a network side device, a congestion status of a target network area sent by a radio access network (RAN) congestion awareness function (RCAF) entity, where the target network area is a network area involved in an application service provided by a target application server; and sending, by the network side device, the congestion status of the target network area to the target application server. Hence, an application server may able to learn in time when congestion occurs, and adjust, according to the congestion situation, a related service in an area corresponding to the congestion situation.

The described technology is generally directed towards an autonomous topology management scheme in a wireless communications network that establishes a hierarchical structure from a peer-to-peer network without assistance from the wireless network. A group of user equipments negotiate with each other to elect a local manager that acts as a base station by which other user equipments of the group can access network resources. Described is an example voting scheme by which the negotiation process elects the local manager for a term.

A packet network includes a plurality of network elements interconnected to one another via a plurality of links, and systems and methods include, responsive to detecting a signal degrade condition on a link in the packet network, advertising the signal degrade condition on the link; maintaining a Traffic Engineering database which includes signal degrade condition status based on the advertising; and, responsive to path computation through the packet network, determining a best path considering the signal degrade condition status of the plurality of links. The systems and methods include further include, responsive to detecting the signal degrade condition on the link has cleared, advertising the signal degrade condition has cleared on the link.

Gateway devices at different sites of a primary Anycast network provide access to the sites by advertising a first set of Anycast addresses. A secondary shadow Anycast network advertises different second sets of Anycast addresses from the different sites in order to predetermine traffic shifts that occur as a result of changing one or more of the second set of Anycast addresses that are advertised from one or more of the sites. A traffic shifting device may implement a predetermined traffic shift in the primary Anycast network by selecting a particular second set of network addresses that produces a traffic shift at least equal to the predetermined traffic shift, mapping the particular second set of network addresses to a modified first set of addresses, and modifying routing in the primary Anycast network by advertising the modified first set of addresses instead of the first set of addresses.

Disclosed are a method and a device for controlling an EVPN route. According to an example of the method, when receiving an EVPN route from a second VTEP device, a first VTEP device checks whether the EVPN route carries a role attribute. When determining that the EVPN route carries a role attribute and the carried role attribute is a specified first role attribute value, the first VTEP device controls the distribution of the EVPN route according to a set route synchronization control strategy.

A network communication system is disclosed that comprises a communicating device that communicates instruction and data signals over a communication link, a user interface device that communicates instruction and data signals related to the communicating device, an administrator server that communicates with the communicating device and the user interface device, and a transceiver device that interacts with the communicating device and generates a communication signal having transaction event data about the interaction, wherein the administrator server retains and manages a client record associated with the communicating device and a partner record associated with the user interface device. The network communication system may comprise an open loop infrastructure or a closed loop infrastructure.

A first flow entry includes match parameters and an action. A second flow entry includes match parameters and which are the same as the match parameters and the action of the first flow entry. The first flow entry and the second flow entry are refreshed.
