the method for inquiring the virtual channel mark through the virtual local area network comprises the following steps of:
assuming that the current virtual local area network is axxb, the first bit of the virtual local area network is fixed to be 1, and the sequence number of the third bit is b, wherein a is the service type, b is the sequence number, and x is the last two bits of the local loopback interface of the control plane;
judging whether the virtual local area network service type is a =3 and the serial number b =9, if yes, indicating that the virtual local area network service type is a moving ring monitoring service and fixing the virtual local area network service type to 139;
if not, obtaining according to the rule table.
8. The system for 5G base station network path restoration based on multi-data fusion as claimed in claim 7, wherein the complete route includes a downlink port of an access layer device of an IP bearer network of a radio access network and a base station IP, and the virtual channel identifier in the configuration data of the convergence layer device of the IP bearer network of the radio access network is CIP configuration data of the access layer device of the IP bearer network of the radio access network.
