Traffic prioritisation measures

Posted: Tuesday, December 8th, 2009 at 15:37 by Steve Lalonde

On 2nd November 2009 we advised that, starting 4th November, Entanet was monitoring new traffic prioritisation measures for approximately three weeks. To remind yourself of the detail please see the NOC notice of 2nd November.

The feedback we have received strongly supports Entanet’s decision to continue to apply the measures as a means of improving the user experience of the majority of customers. As a result our prioritisation measures will continue to be applied. Where customers report access speed issues, we have encouraged Partners to share the experiences with us directly and with specific details so that we can investigate accordingly.

In addition to the Questions and Answers listed in our communication on 2nd November, please make note of the following:

Q: How is traffic prioritised?
A: In order to deliver a better user experience of interactive services, less priority across the DSL network will be given to non-interactive bulk services at times of congestion. However, there are no specific or hard set trigger points at which prioritisation is applied and released on the protocols. Compared to other communications providers that set specific and permanent maximum limits on speed of access to non-interactive bulk services irrespective of bandwidth availability, Entanet’s measures are applied dynamically and traffic types are given the highest possible speed according to their priority versus bandwidth availability in real time.

Q: What traffic types are considered non-interactive bulk services?
A: Peer-to-peer and newsgroups protocols are given lower priority as non-interactive bulk services.

Q: When is traffic prioritised?
A: It is important to note that the prioritisation measures are applied dynamically. This means that, whilst the prioritisation rules run 24/7, varying levels of speed restriction are applied to non-interactive bulk services as the demand for interactive services bandwidth increases. Consequently there may be times when no traffic prioritisation is taking place and all services enjoy a higher speed.

Q: Is the Anti-Loss Tool (ALT) being used?
A: No, the ALT, including the high bandwidth user marking system, is not in operation because we are applying the traffic prioritisation measures.

Please note these measures continue to be monitored and are subject to change.
