We have proposed and implemented a distributed asyn chronous Web-based training (WBT) system. In order to improve the scalability and robustness of this system, all exercises and functions, such as scores user’s answers are realized on mobile agents. These agents are distributed to computers, and they can be constructed with a P2P net work that modified Content-Addressable Network (CAN). In this paper, we present the exercise management scheme for the proposed WBT system. In a WBT system based on client/server model, management of exercises is sim ply achieved by manipulating data, since all contents are concentrated in one server computer. In the proposed sys tem, however, we need to pay attention to distributed agents for management of exercises. In order to achieve opera tion of exercise management, i.e., adding, deleting and up dating exercises on the distributed WBT system, we use steps with considering multi-agent based distributed envi ronment: specifying an agent which provides an exercise and searching its node as pre-operation, and sending an agent to the expected node and notifying other cooperating agents as post-operation.
