Quality of Service(QoS)
The University of Saskatchewan campus network has enabled QOS(Quality of Service) for the campus telephony system. QOS for Video Conferencing systems or other Real Time applications will be included as can be reasonably provided through the identification of the end unit requiring the service.
QOS is a network control mechanism to provide priority service to real time protocol(RTP) data packets like Voice over Internet Protocol(VOIP) in congested network environments.
The QOS service works by dynamically identifying a remote device and trusting the value assigned to the data packet as requiring priority. These packets are then placed for delivery in a high priority queue within the local network access switch. The value of this data packet is trusted by each device as it traverses the network infrastructure and is given priority until it reaches its destination.
This service helps to reduce the latency or jitter impact on the delivery of RTP application packets across the network during periods of network congestion. Where possible this service will be extended to Video Conferencing rooms and mobile devices requiring this service. Current technical limitations prevent a full implementation.
The QOS service can only be provided to resources under the domain of UofS Network Service. End points requiring the use of resources outside the domain of Network Services are subject to the availability of those resources and the powers that govern them.
