%X URE(Ueneric Route Encapsulation) encapsulation is used as the tunneling protocol for the data plane in WiMax network, while the key option is applied on R4 and R6 for providing the DPid(Data Path ID) of the tunnel. DPid assigned by the Data Path Function uniquely identifies a particular tunnel for user payload, and it's area of validity is the NAP. This paper proposed a concept of DPid Server for the effectiveness of the DPid, which is used to store and manage all of the DPids in the NAP, and then a dynamic approach of DPid distribution was presented to guarantee the DPid's uniqueness and safety-reliablely distribution in the NAP. This approach simplifies the processes of DPid distribution,reduces the management difficulty and maintenance costs. Furthermore, this paper also analyzed the design and performance of this approach.
