Patent number: 9088526Abstract: Provided is a communication system which connects a unified C/U router to a network having C/U separation, wherein the stopping of U-plane communication of the unified C/U router is prevented even when the messages transmitted from a C-plane controller of the network having C/U separation do not arrive because of faults in the network having C/U separation. The routing information of a C-plane message (routing protocol) received by a U-plane controller is sent to an adjacent peer without being reflected in a routing table of the U-plane controller. The routing table of the U-plane controller is generated on the basis of the routing information (FIB information) received directly from the C-plane controller. In addition, a keep-alive packet from the unified C/U router is not sent to the C-plane controller and keeps alive the connection with the user router at the transmission destination.Type: GrantFiled: August 29, 2013Date of Patent: July 21, 2015Assignee: Hitachi, Ltd.Inventors: Kazuma Yumoto, Takuji Kawai

Patent number: 8848522Abstract: In a telecommunications carrier network system to provide such a service that a global IP network can be used as a communication infrastructure of a company, especially in a network system in which a setting interface is opened so that a user can freely perform a setting change on a use service, plural users can simultaneously perform setting changes. In a control request classified unit to classify a setting change request from a user terminal, request contents are classified for each of control target node equipments and each of interfaces, and are stored in a control request management unit. An admission control unit collectively judges admission or non-admission of the request for each of control targets. A control request publishing unit collectively orders admissible requests to the same node equipment also when setting update to the node equipment is performed.Type: GrantFiled: February 19, 2009Date of Patent: September 30, 2014Assignee: Hitachi, Ltd.Inventors: Kazuma Yumoto, Takuji Kawai
