Abstract:

This paper studies the QoS arichecture of the triditional IP networks.Through analyzing the basic principle and working mode of the two models: IntServ and DiffServ,the paper points out their merits and demerits as well as their network application environment, respectively. This paper presents a new model which combines the extended RSVP protocol and the DiffServ model to provide the QoS guarantee strategy of big campus networks. From the emulation test results, we can see that the application of the new model can promote the QoS characteristics of big campus networks effectively.
