An outer label encoding method, traffic congestion control method and device, the outer label encoding method comprising: a PE head node encodes an EXP field of the outer label of a packet according to the class of service of an ingress node PHB of the packet and the packet color information, the EXP field comprising a first field for identifying the class of service of the packet and a second field for identifying whether the packet is a virtual private network service packet within a committed bandwidth when entering a pseudo wire of the PE head node, such that a P node can map PHB according to the EXP field, manage and control congestion of each queue in each tunnel, and conditionally perform two-level QOS scheduling management, thus solving the problem in the relevant art of being unable to achieve end-to-end QoS control due to the failure of a P node to obtain VPN information in the case of multiple VPN service multiplexing a tunnel in an E-LSP based MPLS network. |
