Communication system and communication control method
First Claim
1. A communication System comprising a plurality of communication devices,the communication system having a communication path configured by connecting a Starting-point device to an end-point device so as to be capable of communicating via at least one relay-point device, the starting-point device being one of the plurality of communication devices, the end-point device being one of the communication devices other than the starting-point device among the plurality of communication devices, and the relay-point device being a communication device other than the starting-point device and the end-point device among the plurality of communication devices, andthe communication system comprising:
- a communication path determined band acquiring unit for, for each of sections between communication devices adjacent to each other in the communication path, acquiring a section available band that is a communication band available in the section, and acquiring, as a communication path determined band, a smallest value between the acquired section available band and a communication path request band that is a communication band requested for the communication path;
a band reserving unit for reserving a communication band in the communication path by reserving the acquired communication path determined band in each of the sections configuring the communication path; and
a communication traffic controlling unit for transmitting communication traffic so that the communication traffic passes through the communication path where the communication band is reserved, the communication traffic satisfying a traffic flow condition including a condition that a transmission source communication device is the starting-point device and a transmission destination communication device is the end-point device.

Abstract
A communication system 100 has a communication path configured by connecting a starting-point device to an end-point device so as to be capable of communicating via at least one relay-point device. The communication system 1000 includes: a communication path determined band acquiring part 1001 that, for each of sections between communication devices adjacent to each other in the communication path, acquires a section available band, and acquires the smallest value between the section available band and a communication path request band that is a communication band requested for the communication path, as a communication path determined band; a band reserving part 1002 that reserves the acquired communication path determined band in the communication path; and a communication traffic controller 1003 that transmits communication traffic satisfying a traffic flow condition so that the communication traffic passes through the communication path where the communication path is reserved.

10. A communication control method applied to a communication system including a plurality of communication devices, the communication system having a communication path configured by connecting a starting-point device, to an end-point device, so as to be capable of communicating via at least one relay-point, device, the starting-point device being one of the plurality of Communication devices, the end-point device being one of the communication devices other than the starting-point device among the plurality of communication devices, and the relay-point device being a communication device other than the starting-point device and the end-point device, among the plurality of communication devices,
the communication control method comprising: -
for each of sections between communication devices adjacent to each other in the communication path, acquiring a section available band that is a communication band available in the section, and acquiring, as a communication path determined band, a smallest value between the acquired section available band and a communication path request band that is a communication band requested for the communication path; reserving a communication band in the communication path by reserving the acquired communication path determined band in each of the sections configuring the communication path; and transmitting communication traffic so that the communication traffic passes through the communication path where the communication band is reserved, the communication traffic satisfying a traffic flow condition including a condition that a transmission source communication device is the starting-point device and a transmission destination communication device is the end-point device. - View Dependent Claims (14, 15)
