QoS and Delivery Context in Rule-Based Edge Services

As the Internet grows, more and more content distribution networks are deploying services at the network edge to effectively perform content adaptation. In a wireless web environment where bandwidth resource is expensive, edge services requires information such as the Quality of Service (QoS) to perform optimal bandwidth adaptation. In addition, due to the diversification of wireless device accessing the Internet, it is necessary to provide an extensive set of information on the wireless device so that edge services can be carried out efficiently. A complete collection of such information is known as Delivery Context. We describe the use of sub-systems in an Open Pluggable Edge Services (OPES) intermediary to provide edge service agents the needed QoS and delivery context information.
