Abstract:
Effects on communication services caused by re-establishment of a communication path are suppressed when resource control is performed in a communication system. A communication apparatus according to the present invention is a communication apparatus in a communication system providing communication services to a terminal through a communication path associated with the terminal, and includes: a first means capable of switching a plurality of first sessions set up between the communication apparatus and a network node to a plurality of second sessions corresponding respectively to the plurality of first sessions; and a second means capable of sending to the network node a control signal including information related to the plurality of second sessions.
Abstract:
A communication technique, a control technique, and a management technique are provided that can suppress effects on communication services caused when switching a communication path route. A communication apparatus (4) which performs communication over communication paths configured in a network includes: a first means for identifying a communication path group corresponding to the communication paths to one of which a received packet belongs; and a second means for forwarding the received packet to a network node associated with the communication path group corresponding to the received packet, among a plurality of network nodes which can terminate the communication paths.
Abstract:
A communication system includes a network device to be used for packet handling; and a controller capable of sending, to network device, a packet handling rule according to a first protocol.The network device classifies, based on a condition, indicative of a scope under which the controller is capable of controlling the network device, whether to handle the packet according to the packet handling rule sent from the controller or to handle the packet according to a table entry that the network device autonomously sets based on a second protocol.
Abstract:
A communication technique and a communication path control technique are provided that can suppress effects on communication services caused when switching a communication path route. A communication apparatus (4) which performs communication through a communication path configured in a network, includes: a first means that can receive a packet routing policy which indicates a gateway (3) associated with the communication path from a control apparatus (5) which can send a control single concerning the communication path to the communication apparatus; and a second means that can forward the received packet to the gateway associated with the communication path to which the received packet belongs, based on the packet routing policy.
Abstract:
A communication system, a communication apparatus, a control method, and a control apparatus are provided that make it possible to flexibly increase/decrease a U-plane processing function of a communication apparatus. A communication system in which a logical path (50) is set up in a network to perform communication, comprises: a control plane (30) for the logical path; and a control apparatus (20) that, in response to a request from the control plane, selects from communication equipment resources a communication equipment (10) to perform user-plane processing in connection with data transmission through the logical path, and sets an operation rule related to the user-plane processing in the selected communication equipment.
Abstract:
A communication system, a serving gateway, a communication method, and a base station are provided that make it possible to flexibly increase/decrease a U-plane processing function of a communication apparatus. A communication system in which a logical path is configured in a network to perform communication, comprises: second gateways (740-1, 740-2), which are deployed for a plurality of first gateways (720-1, 720-2), respectively; a transport network (760), which the logical paths configured between a base station (770) and the second gateways pass through; and a control apparatus (710) that controls packet forwarding in the transport network, wherein the control apparatus controls the transport network so that a logical path to which a packet belongs is identified and the packet will be forwarded to the second gateway corresponding to the identified logical path.
