Abstract

A method for implementing switching when the network is faulted is disclosed, and the method includes: establishing a quick detection mechanism between non-querier and querier; the non-querier using the detection mechanism for performing a real-time detection on the querier and downlink of the querier; switching the non-querier to be the querier when the non-querier detects that the querier or the downlink of the querier is faulted. A querier is further disclosed. With the method, it can complete a quick switching of the querier and a quick transmission of a multicast flow when the querier or the downlink thereof is faulted, thereby reducing the interrupt time of users receiving the multicast flow, implementing a quick protection of a multicast service, and improving the service experience for the user.
