On Modeling VoIP Traffic in Broadband Networks
With the general trend towards ubiquitous access to the Internet, more users will prefer to make voice calls through the Internet. VoIP as the application which facilitates voice calls through the Internet will increasingly occupy more of the Internet traffic. The growth of delay sensitive traffic that requires special quality of service from the network will impose new constraints on network designers who should wisely allocate the limited resources to users based on their required quality of service. An efficient resource allocation depends upon gaining accurate information about the traffic profile of user applications.
