(UAC) like characteristics of an S-CSCF. To show its efficiency, the session transfer delay and the traffic cost of RSA session transfer are investigated and compared with those of existing session transfer applications, including Assured and Consultative session transfers, by practically considering multiple session transfer failures. It is shown that RSA session transfer can further improve u...

In this paper we present a simulation study of HTTP traffic crossing a DiffServ domain. We consider both the cases where the reserved bandwidth is not exceeded by the offered traffic (overprovisioning) and where the assured traffic competes with the classic Best Effort class (underprovisioning). Simulation reported shows that DiffServ approach is able to protect the assured flows in the first c...
