MPLS PACKET ENCAPSULATION METHOD AND APPARATUS, AND STORAGE MEDIUM AND ELECTRONIC APPARATUS

Provided in the embodiments of the present disclosure is an MPLS message encapsulation method. The method comprises: setting an MPLS manage header in a stack bottom structure of an MPLS label stack, where the MPLS manage header is located after a stack bottom label and prior to ancillary data; the MPLS manage header includes: a data type and offset length information of the ancillary data; and the stack bottom structure includes: the MPLS manage header and the ancillary data. By means of the technical solution, the problems in the related art of high complexity, low efficiency, etc. of an indication mode of an MPLS label stack are solved.
