Network management configuration

Usability of federated trust management systems is mainly reflected in user awareness. After a user has deployed a trust management system, operation should be autonomous unless the system actively requires a user's involvement. These two aspects are explained in detail. Other factors such as understandability, operability, user involvement, and user's acceptance will be discussed in the actual comprehensive comparison of existing systems.

Following the four network management configuration aspects and three important evaluation perspectives discussed in section 2 and 4, a set of comprehensive evaluation metrics will be discussed and used to compare the six major trust management systems, and especially for their support of federation activities. This set of evaluation metrics is divided into four groups and examined from three evaluation perspectives. After this comparison, strength and weakness of each system can then be analyzed. And direction for further improvement of each system can be identified. The evaluation data are collected from a number of server systems. Each system runs on a Xeon 2.80GHz processor, 512MB memory, and the Windows XP professional version.
