An adaptive communication middleware for network service coordination

In today´s Internet, which includes diverse and complex network technologies and services, it is difficult to achieve ´comfortable communication´ that satisfies network users from the viewpoint of aspects such as communication usability, availability, quality and safety. To alleviate these problems and make communication a comfortable experience for users, we have developed a middleware named communication service concierge (CSC). CSC focuses on communication dataflow and coordinates various resources affecting the behavior of the flow, such as network applications, protocols, network devices and computing equipment. These elements can be scattered throughout the end-to-end communication link of the dataflow. CSC provides a distributed communication control framework, which improves user satisfaction on the basis of agent computing using configurable and downloadable software components. The paper briefly describes the design concept and basic architecture of CSC, as well as two prototype applications for it that are associated with home networking and mobile computing. These are the most effective ways in which CSC helps users to achieve more comfortable communication.
