Patent Number Title Of Patent Date Issued
8201221 Data transmission control on network June 12, 2012
Enables control of data transmission within a network. For this, for example, a network relay apparatus makes a determination as to permission to transmit data, based on a condition relating to at least one of the transmission origin of the data and transmission destination of the data.
7827446 Failure recovery system and server November 2, 2010
A server 200 includes a scenario table in which object to-be-monitored information that indicates one or more network devices A, B and C being objects for failure recovery, failure information for identifying contents of failures, countermeasure information against failures, and freq
7817637 Network switching system October 19, 2010
A handling address range is pre-assigned to each of switching devices consisting a network switching system. The switching device has a data receiving unit, an assigned data transport unit, an unassigned data transport unit, and a lower transport layer transport unit. The data receiv
7792016 Network relay device for relaying data in a network and control method for the same September 7, 2010
In the case of detection of failure on a direct link interconnecting Master and Backup upstream switches, a control module of the Master upstream switch sends a partial failure message representing the occurrence of partial failure in the Master upstream switch via any of multiple li
7778266 Switch and network fault recovery method August 17, 2010
A first switch flashes an FDB upon receiving an FDB flash frame and then floods a multicast group join query message (QRY1). A terminal sends a group join message (RP1) back to the first switch. A second switch, a third switch and the first switch receive RP1 and perform IGMP/MLD sno
6237038 Method of data communication and system for carrying out the method May 22, 2001
A data communication system comprising a system processor, an application program assigned to an application buffer it controls, a communication protocol program assigned to a protocol buffer it controls, a communication controller for controlling communication lines, and transmittin
5845061 Redundant client server system December 1, 1998
A client server system has clients, a server of execution system, and a server of fault auxiliary system are connected. A process administrator is provided in each one of the server of execution system and the server of fault auxiliary system. When a fault has occurred in a disk processo
5799155 Method of data communication and system for carrying out the method August 25, 1998
A data communication system comprising a system processor, an application program assigned to an application buffer it controls, a communication protocol program assigned to a protocol buffer it controls, a communication controller for controlling communication lines, and transmittin
