PRISTINE recently participated in an interactive discussion at the BroadBand World Forum 2015, in which ”Fit for Purpose Networks” along with the evolving nature of QoE based networks to enable the Future Internet was hotly discussed.
The BroadBand World Forum is one of the world’s largest telecoms, media & technology events. Pulling in over 7,800 senior executives from across the globe. During the Network Intelligence session, PRISTINE project co-ordinator Miguel Ponce de Leon, got a chance to discuss a long term communication network strategy that can support the developing digital economy with John Strand (Strand Consult) and Jon Aldington (GOETEC), along with Martin Geddes, a chief proponent of Fit for Purpose Networks.
The session got a chance to highlight that more speed DOES NOT equal more value for broadband consumers and that in fact the global industry’s obsession with speed is failing to deliver value to consumers. It is now becoming clear that the internet is at its limits, and that broadband services need the capability to meet their performance and availability needs. This in turn demands that operators look at new metrics and measures, since capacity alone fails to capture the needs for continuity, connectivity, and consistency.
The overall pitch from PRISTINE is that with RINA an operator can make business promises on QoE that can be delivered ! The DIF API allows applications (and other layers) to request quality characteristics for their flows, such as delay, loss, and in-order-delivery of data to name a few. Then each DIF can allocate resources and schedule the packets belonging to different flows in order to comply with the promised flow characteristics. The usage of proper resource allocation and scheduling policies in each DIF is then key to deliver the quality promised to each flow.
Quality attenuation is a framework to reason about the performance of statistically multiplexed packet networks, providing a scheduling model that allows to differentially allocate delay and loss between classes of competing flows. PRISTINE is investigating the Integration of quality attenuation as a resource allocation and scheduling framework for DIFs, and comparing them to the use of other scheduling policies such as weighted fair queueing.
