CMSNS: a communication middleware for social networking and networked multimedia systems

In this paper, we propose a communication middleware for social networking services (CMSNS) in order to reduce the development effort and to support high accessibility to remote social content such as text, image, and video. The main role of CMSNS is to provide a developer with simple application programming interfaces (APIs) and configuration options related to communication among users. With CMSNS, a developer can easily build communication-related functions which are commonly required in SNS and networked multimedia systems such as the management of communication architecture, user registration and authentication, and synchronous / asynchronous sharing of content among users. In addition to the simple development model, CMSNS enables a server to dynamically adjust the amount of SNS content to be downloaded at a client according to current network conditions. With this scheme, a user can access as much content as possible within an acceptable delay, which enhances the accessibility to remote content.
