<p>An automatic protection switching method, equipment and system are provided in embodiments of the present invention. The method includes: determining a part of service is a service to be switched according to a bandwidth change status when the bandwidth change of a first transmission path is monitored; and switching the service to be switched between links of a second transmission path and the first transmission path. Another method includes: receiving a part switching message from a network edge node in an opposite side via the first transmission path or the second transmission path; determining the service to be switched according to indication information of the service to be switched or the bandwidth change status in the part switching message; and switching the service to be switched between links of the first transmission path and the second transmission path. By adopting technical means relating to perform protection switching on the part of service, the embodiments of the present invention can reasonably utilize the bandwidth resources of every transmission path, and reduce switching quantity of the service, thus reasonably sharing load in every transmission path, and improving transmission efficiency and quality of the service.</p> |
