A control apparatus includes a packet handling operation setting unit that sets a packet handling operation for processing a packet for a communication node selected from a plurality of communication nodes. The packet handling operation setting unit sets the packet handling operation for communication nodes out of the plurality of communication nodes other than the selected communication node, in response to the fact that it was possible to set the packet handling operation for the selected communication node.

Method for receiving information, method for sending information, and apparatus for the same

The present invention provides a method for receiving information, a method for sending information, and apparatuses for the same. The method for receiving information includes: when a control plane apparatus is capable of managing a forwarding plane apparatus, receiving, by the forwarding plane apparatus, information used for packet forwarding path calculation sent by the control plane apparatus, where the forwarding plane apparatus and the control plane apparatus are located in a network with a network architecture featuring forwarding and control element separation. According to the technical solutions provided in embodiments of the present invention, the forwarding plane apparatus does not need to actively obtain the information used for packet forwarding path calculation before calculating a packet forwarding path based on the information used for packet forwarding path calculation.

20170242730 · 2017-08-24 ·

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.

Using PCE as SDN controller

Embodiments relate generally to systems and methods for transitioning a system from a tradition network to a Software Defined Network (SDN) enabled network. In some embodiments, the systems and methods may comprise the use of a Path Computation Element (PCE) as a central controller. Smooth transition between traditional network and the new SDN enabled network, especially from a cost impact assessment perspective, may be accomplished using the existing PCE components from the current network to function as the central controller of the SDN network is one choice, which not only achieves the goal of having a centralized controller to provide the functionalities needed for the central controller, but also leverages the existing PCE network components.

A computer executes a first determination procedure determining a first link which at least partially overlaps a disaster area representing a range reached by an influence of a predetermined disaster, among links constituting a network, a second determination procedure determining a second link which at least partially overlaps a road area representing a range of a road width of a predetermined road used to recover from the disaster, among the links constituting the network, a route search procedure searching for a plurality of routes from a start point node to an end point node constituting the network, a grouping procedure grouping the plurality of routes searched for by the route search procedure into groups depending on a first parameter value that is based on the first link included in the routes, a computing procedure computing, for each of the plurality of routes searched for by the route search procedure, a second parameter value that is based on the first link and the second link included in the routes, and a selecting procedure selecting a predetermined number of routes among one or more routes grouped into the same group on the basis of the second parameter value computed by the computing procedure for each of the groups grouped by the grouping procedure.

PIECEWISE SHORTEST PATH FIRST ROUTING

A method and apparatus for routing packets in a network, such as a satellite mesh network. Geographic routing is employed in which packets specify their physical destination location. Network nodes maintain physical location information for nodes, along with routing information, for a limited portion of the network which is local thereto. At each node and for each packet, a target node is selected from the limited portion. The target node may be the node which is closest in orthodromic distance to the physical destination location. Based on the routing information, a route through the limited portion of the network to the target node is determined, other nodes are configured (e.g. via source routing) to cause the packet to traverse the determined route, and the packet is forwarded toward the target node.
