Abstract: Under the virtual network dynamic routing is large, complex, different formats, the current dynamic routing messages transformation method by extracting feature implementation message transformation and conversion accuracy is low, therefore, puts forward a new method of dynamic routing message transformation, analyses the standard particle swarm algorithm and genetic algorithm, this paper introduces the virtual network under the principle of dynamic routing message transformation, to determine the dynamic routing based on message transformation rules of each standard message in the transformation model, builds the corresponding objective function message transformation, by particle swarm optimization (pso) algorithm and ant colony algorithm to modify message transformation model parameter values, make the error minimum value, ensure the consistency of the message before and after the transformation.The experimental results show that the proposed method has a high conversion accuracy, and lower conversion message before and after independence, high conversion efficiency.
