Abstract
The service identifier and connection identifier mapping theory was analyzed in a new two-layer universal network. Optimization models are proposed for the four types of mapping from service identifier to connection identifier in the pervasive service layer based on the utility maximization for services. For the nonlinear optimization problem, elastic services with concave utility function are firstly considered and the optimal flow rate for these services can be obtained. For the inelastic services with sigmoidal utility function, the optimal flow rate allocation can also be obtained if the capacities of some connections are provided with certain values. Furthermore, the model for inelastic services with QoS guarantee and the model for services with priority are also presented. Some numerical examples are given to verify the results obtained.
