Tromsø And Cornell Moving Agents (TACOMA)

The TACOMA project focuses on operating system support for agents; and how agents can be used to solve problems traditionally addressed by other distributed computing paradigms, e.g. the client / server model. We have completed a series of TACOMA distributed systems where agents can be moved about in the Internet.

An agent in TACOMA is a piece of code that can be installed and executed on a remote computer. Such an agent may explicitly migrate to other hosts in the network during execution. We are currently focusing on fault-tolerance, security, applicability and management issues. The TACOMA platform has also been ported to new operating system architectures, in particular Windows NT, Windows CE and the PalmOS.

Several TACOMA applications are under construction. One example is a wide-area network weather monitoring system accessible over the Internet. This distributed application is StormCast. We are also investigating whether agents can be useful in extensible file system architectures.
