NOMAD
a Distributed Systems Research Group Project

---

Nomad is a software architecture that provides support for mobile, distributed applications, allowing such applications to locate and obtain resources where and when they are needed.

Negotiated - Object - Migration - Access and - Delivery

Overview

Today's applets are forerunners of globally distributed mobile systems. These future systems will consist of a distributed set of objects that will move from one location to another delivering a service when and where it is required. Such nomadic applications will need to seek out and acquire resources wherever they may find the need to provide a service.

The NOMAD architecture provides a set of globally distributed Depots which are able to provide resources for mobile objects. A group of Depots may be collected under a single management regime forming a DepotNet. Nomadic applications negotiate with a DepotNet and its Depots for the purchase of the resources they require.

The Depots provide a set of services in addition to basic computational resources.

Communication

Both messaging and and method invocation between the objects of an application and between the application and its clients is transparent to the current location of the application's objects.

Mobility

Objects may move amongst Depots in order to more effectively deliver their service.

Location

Depots are able to locate application services for clients and to locate the various objects of a client.
