Design of Agent-based Middleware for Extranet Management

Vol. 7  No. 6  pp. 17-26


We propose a novel, agent-based middleware for efficient management of an extranet. To keep an extranet in full working order, its network connections (e.g., routing, bandwidth assigning, etc.) have to be customized for the specific network services in a particular group. However, such customization work imposes a heavy workload on the extranet administrator, and this makes it very difficult to achieve efficient management of the extranet. To overcome this difficulty, we propose an agent-based middleware between the application layer and the transport layer of the extranet. This middleware controls network connections based on known specifications of the extranet, and thus it provides well-customized network connections for users and extranet applications. In this paper, we explain the design of the proposed agent-based middleware, describe its implementation, and report on experimental results.
