This scheme requires that the agents and messages are transmitted through an imposed logical tree-shaped hierarchy of runtime servers. We present the procedures for building and maintaining the domain gateway hierarchy. Using this scheme, the cost of locating an agent is asymptotically bound by O(lg n) on the number of hops, while the agent registration is achieved at no additional cost.","PeriodicalId":321059,"journal":{"name":"Proceedings Seventh IEEE International Workshop on Enabling Technologies: Infrastucture for Collaborative Enterprises (WET ICE '98) (Cat.

The Web is about sharing artifacts, passing them around, and sometimes working together on them simultaneously. The MUDs are about shared presence, with people interacting with each other and their tools, in a common environment. We focus on MUDs, because their capabilities and potentials are not very well known.","PeriodicalId":321059,"journal":{"name":"Proceedings Seventh IEEE International Workshop on Enabling Technologies: Infrastucture for Collaborative Enterprises (WET ICE '98) (Cat.

Several approaches have been published that aim at coordinating large projects in general, and large software development processes specifically. However most of these approaches focus on the technical part of the design process and omit management activities like planning and scheduling the project, or monitoring it during execution. We focus on coordinating the management activities that accompany the technical software design process. We state the requirements for a Software Engineering Environment (SEE), accommodating management, and we describe a possible architecture for such an SEE.","PeriodicalId":321059,"journal":{"name":"Proceedings Seventh IEEE International Workshop on Enabling Technologies: Infrastucture for Collaborative Enterprises (WET ICE '98) (Cat.

We propose a series of novel approaches for achieving scalable security in IP multicast, providing privacy and authentication on a group-wide basis. They can be employed to efficiently secure multi party applications where members of highly dynamic groups of arbitrary size may participate. Supporting dynamic groups implies that newly joining members must not be able to understand past group communications, and that leaving members may not follow future communications. Key changes are required for all group members when a leave or join occurs, which poses a problem if groups are large. The algorithms presented here require no trust in third parties, support either centralized or fully distributed management of keying material, and have low complexity (O(log N) or less). This grants scalability even for large groups.","PeriodicalId":321059,"journal":{"name":"Proceedings Seventh IEEE International Workshop on Enabling Technologies: Infrastucture for Collaborative Enterprises (WET ICE '98) (Cat.
