Embodiment Construction
[0039]In the MPLS+Diffserv system, the Label Switching Router (LSR) in the MPLS network is required to perform per-hop forwarding behavior (PHB, Per-Hop Behavior) for the carried Diffserv-related packets, which requires the LSR to be able to obtain PHB information. The priority-based LSP (E-LSP) is a scheme for representing the PHB by using the 3-bit EXP in the LSP label, therefore, the LSR can determine the PHB through the E-LSP. The 3-bit EXP in the E-LSP can also represent 8 QoS levels, so that an E-LSP can be divided into 8 QoS levels through this EXP, that is, an E-LSP can be divided into 8 types, each for different QoS level.
[0040] The solution of the present invention is mainly based on the above situation, setting the corresponding relationship between the service type and the QoS level in the E-LSP, and enabling the bearer control layer to determine the QoS level, so that the bearer control layer allocates corresponding service flows according to the QoS level.
