far greater than 1, the competitive rate of greedy distribution algorithm is close to 1, and the allocation efficiency is close to the optimal allocation algorithm. Therefore, the greedy allocation algorithm is a good allocation algorithm when the advertisement main bid difference is big .The above survey is the order of the flow arrival sequence in the worst case, greedy allocation algorithm competition rate. In a real world, traffic arrival order is generally not the worst case scenario. Ther
