【Abstract】 A kind of new minimum interference routing algorithm JMIRA was proposed. It is composed of two parts, they are off-line network optimization and on-line dynamic routing. The on-line routing part adopted an admission control mechanism and utilized shortest-narrowest routing method to go to a few critical links. It computed link’s weight based on the ratio of used and usable bandwidth for all types of traffic in order to lower the algorithm complexity and achieve the purpose of minimum interference at the same time. Simulation results indicate that the algorithm performs better than the traditional algorithms in aspects of network usable-bandwidth and request rejection ratio, etc.更多还原
