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...
متن کاملAnalytical 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...
متن کاملInternet Engineering Task Force (ietf) Pre-congestion Notification (pcn) Boundary-node Behavior for the Single Marking (sm) Mode of Operation
Pre-Congestion Notification (PCN) is a means for protecting the quality of service for inelastic traffic admitted to a Diffserv domain. The overall PCN architecture is described in RFC 5559. This memo is one of a series describing possible boundary-node behaviors for a PCN-domain. The behavior described here is that for a form of measurement-based load control using two PCN marking states: notm...
متن کاملEncoding Three Pre-Congestion Notification (PCN) States in the IP Header Using a Single Diffserv Codepoint (DSCP)
The objective of Pre-Congestion Notification (PCN) is to protect the quality of service (QoS) of inelastic flows within a Diffserv domain. The overall rate of PCN-traffic is metered on every link in the PCNdomain, and PCN-packets are appropriately marked when certain configured rates are exceeded. Egress nodes pass information about these PCN-marks to Decision Points that then decide whether to...
