Analytical Study of Pre-Congestion Notification (PCN) Techniques

Analytical Study of Pre-congestion notification (PCN) techniques

Maintaining the quality of service (QOS) and controlling the network congestion are quite complicated tasks. They cause degrading the performance of the network, and disturbing the continuous communication process. To overcome these issues, one step towards this dilemma has been taken in form of Pre-congestion notification (PCN) technique. PCN uses a packet marking technique within a PCN domain...

A Simple Analytical Model for Pre-Congestion Notification (PCN)

Analytical Model of Pre-Congestion Notification (PCN) for Multimedia Traffic over DiffServ Domains

IETF Pre-Congestion Notification (PCN) working group is working on mechanisms to ensure quality of service of voice and video traffic within a DiffServ domain in the Internet. These mechanisms operate at the domain boundary based on congestion information from within the domain. The reaction mechanisms at the boundary consist of flow admission and flow termination. In this paper, we present a s...

Preliminary Performance Evaluation of Admission Control in Load Control Pre-Congestion Notification (LC-PCN)

The Differentiated Service (DS) framework has been developed by the Internet Engineering Taskforce (IETF) to provide Quality of Service (QoS) on the Internet. Load Control Pre-Congestion Notification (LC-PCN) is a measurement based DiffServ implementation that uses Admission Control and Flow Termination to control the load in a domain. In this paper a preliminary performance evaluation of Admis...
