The Automated Network Games Enhancement Layer (ANGEL) project aims to leverage Machine Learning (ML) techniques to automate the classification and isolation of interactive (e.g. games, voice over IP) and non-interactive (e.g. web) traffic. This information is then used to dynamically reconfigure the network to improve the Quality of Service provided to the current interactive traffic flows and subsequently deliver improved performance to the end users. Within this scope, the project will develop protocols that allow the adjustment of Consumer Premise Equipment (CPE - eg. cable/ADSL) configuration to provide better quality of service to interactive flows detected in real-time. This document describes the protocol to be used between ANGEL enabled Consumer Premise Equipment (CPE) and the ANGEL ISP System. The purpose of this document is to ensure inter-operability between ANGEL enabled components developed by different vendors. The ANGEL Prototype system utilises this protocol.
