[0035] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0036] In order to implement DiffServ in MPLS, it is necessary to add an object related to DiffServ - DiffServ object in the Path message of establishing LSP, carrying DiffServ parameters.
[0037] FIG. 1 is a schematic structural diagram of a DiffServ object in a Path message. As can be seen from Figure 1, DiffServ objects include:
[0038] Reservd field: 28 bits, this field is reserved, set to 0 when sending, and ignored when receiving;
[0039] MAPnb field: 4 bits, indicating the number of MAP entries contained in the DiffServ object, and its value is between 0 and 7;
[0040] MAP fi...
