Patent ID: 8416747

Claim:
A method for path switchover, comprising: detecting communication quality of traffic transmitted on an active path and obtaining a detection value of the communication quality; determining whether the detection value meets a switching condition; switching the traffic transmitted on the active path to a standby path, if the switching condition is met; determining whether a switchback condition is met after the traffic is switched from the active path to the standby path; and switching the traffic transmitted on the standby path back to the active path if the switchback condition is met; wherein the determining whether a switchback condition is met comprises: obtaining a first detection value and a second detection value in turn; and determining whether the first detection value reaches a first preset reference value and determining whether the second detection value reaches a second preset reference value; wherein the switchback condition is met when the first detection value reaches a first preset reference value and the second detection value reaches a second preset reference value; the switchback condition is not met when the first detection value does not reach a first preset reference value or the second detection value does not reach a second preset reference value.
