Patent number: 8831018Abstract: A gateway device includes a SIP server and a media converter. The SIP server uses media communication control data output from communication terminal devices (CTDs) to discriminate the communication media standards adopted by the CTDs, based on a call control, to call-control the CTDs. The media converter uses the communication media standards discriminated and acquired to convert media data, delivered from the CTDs, involved in communication, to a signal of a relevant communication media standard. The SIP server causes the communication media standard and information used for communication to be stored in an information memory. The media converter includes input/output interfaces, a controller, a media converter circuit and a data switcher. The interfaces verify whether or not the received data is media data, the media converter circuit converts the communication media standard of received media data received from the source CTD to a communication media standard of the destination CTD.Type: GrantFiled: August 9, 2012Date of Patent: September 9, 2014Assignee: Oki Electric Industry Co., Ltd.Inventor: Shugo Shiba

Publication number: 20140204752Abstract: A packet processing apparatus includes plural packet processors processing input packets constituting an input packet stream. A flow identification information manager holds flow identification information about flows included in the input packet stream. A flow assigner assigns each of the flows to one of the packet processors. A packet identifier determines, based on the flow identification information, one of the flows to which the input packet belongs. A packet distributor supplies the input packet to the determined packet processor according to a result of determination made by the packet identifier.Type: ApplicationFiled: December 19, 2013Publication date: July 24, 2014Applicant: OKI ELECTRIC INDUSTRY CO., LTD.Inventor: Shugo SHIBA

Patent number: 6697853Abstract: According to the present invention, if an EMS110 needs to conduct control over a prescribed group of nodes 120 in the IP network 140 to exert a predetermined function, that is, to change the control mode, it creates, according to a control program, an active program AP which stores a control-subject address table and control contents of that group and then transfers it through a control network 150. At each node 120, if the active program executed by itself has normally ended, records this normal ending in the control-subject address table of the active program AP and also, based on this control-subject address table, transmits the active program to such a node 120 in the control-subject group that has not executed that program yet. If the active program AP has abended, on the other hand, it records this abending in the control-subject address table of the active program AP and also transmits the active program AP to the EMS110, thus suspending the control processing.Type: GrantFiled: January 25, 2002Date of Patent: February 24, 2004Assignee: Oki Electric Industry Co., Ltd.Inventor: Shugo Shiba
