| 发明名称 | Failure protection method and node apparatus | ||
| 摘要 | A failure protection method of a network connecting between nodes by multiple working paths and a protection path is disclosed. An allocation bandwidth is determined to allocate to a detected path where a failure is detected in multiple paths being set to the multiple working paths, depending on the detected path. The detected path is switched from one of the multiple working paths to the protection path. Data to be transmitted by the detected path is transmitted by using the allocation bandwidth determined within an entire bandwidth of the protection path. | ||

| 主权项 | 1. A failure protection method of a network connecting between nodes by multiple working paths and a protection path, the failure protection method comprising: determining, respectively, a first allocation bandwidth and a second allocation bandwidth to allocate to a first detected path and a second detected path in each of which a failure is detected, in multiple paths being set to the multiple working paths, depending on the first detected path and the second detected path; switching the first detected path and the second detected path from two of the multiple working paths to the protection path; and transmitting data to be transmitted by the first detected path and the second detected path, by using the first allocation bandwidth and the second allocation bandwidth determined within an entire bandwidth of the protection path. | ||
