Provisioning Dedicated Class of Service for Reliable Transfer of Signaling Traffic

In IP QoS (Quality of Service) networks, classes of service for different kinds of data traffic have been proposed, analyzed and currently implemented. On the contrary, signaling traffic has been mostly considered as negligible. However in the last time, it has become more critical due to the necessity of controlling setup latencies. As a consequence, a new class of service (CoS) dedicated to carry the user signaling traffic was proposed by IETF. This paper deeps into the signaling CoS and proposes a model for its provisioning. It also considers the impact of timers (for reliable data transfer) on the network load and the setup latencies. It concludes aspects about the transport protocols used for the signaling class of service.
