JANET QoS

Quality of Service (QoS) is a technology that counters the effects of congestion and queues in packet-switched networks, at the same time keeping the advantages of those networks such as high throughput and dynamic re-allocation of bandwidth between users. QoS divides network traffic into different classes during periods of congestion, and processes those classes in different ways depending upon their characteristics. A more detailed overview of QoS technology is available.

Currently no production QoS services are provided across JANET. At the same time the overprovisioned core of JANET is and will be kept QoS transparent, allowing regional and campus network operators to deploy QoS through JANET on a case by case basis if they decide to do so.

The recommendations and technical guidance focusing on access links between regional networks and JANET connected organisations where QoS might be needed are available here.

The full statement about the JANET(UK) position regarding QoS on JANET is available.

The JANET QoS Development Project ran between 2002 - 2007; its results and findings formed the current positioning of QoS on JANET.
