A Learning-Based Approach to Intra-Domain QoS Routing

In traditional networks, routing table is essential for packet transmission due to the lack of the direction information about destination in the head of packet. However, it is feasible to make the address of device encode the routing information with the application of data technology. In this article, we propose new identities for networking routers -vectors, and a new routing principle based on these vectors is designed accordingly. These vectors encode the device distance information and serve as a pattern of the network topology. Then, routing decisions could be made by these vector calculations and only requirement of table query on the destination vector following the proposed routing principle. The proposed method is not limited in calculating the shortest path routing, but extend to solve the constrain routing problem. Besides, multi-paths routing is also available as long as multi-paths exist between the origin-destination pairs. The simulation results show that our proposed method works reliable and stable in routing tasks, and can achieve a remarkable performance when compared with the state-of-the-art work on the delay constrained least cost path (DCLC) problem.
