In the recent years a form of software development that was previously dismissed as too ad-hoc and chaotic for serious projects has suddenly taken the front stage. With products such as Apache, Linux, Perl, and others, open-source software has emerged as a viable alternative to traditional approaches to software development. With its globally distributed developer force and extremely rapid code evolution, open source is arguably the extreme in "virtual software projects" [1], and exemplifies many of the advantages and challenges of distributed software development.
There are two general approaches to providing for isochronous streams in the current Internet. The first approach is the resource reservation approach through protocols such as RSVP, or ATM technology. This provides bandwidth guarantees, however, it also requires significant upgrading of resources in the underlying network. The other common approach is adaptive rate control where the end-system has control of its rate according to feedback from the client population. This approach cannot guarantee timely delivery and raises some scaling questions, however a properly implemented scheme does improve quality and it requires no changes to the underlying IP network. Hence, there exists a dichotomy of requirements ; 1. To cater for reservation protocols or 'hooks' for future reservation components, and 2. To provide an architecture which provides an application controlled QoS scheme, which scales to the size of the current Internet in a best- effort architecture.
This paper describes a system that supports softwaredevelopment processes in virtual software corporations. A virtual software corporation consists of a set of enterprisesthat cooperate in projects to fulfill customer needs. Contracts are negotiated in the whole lifecycle of asoftware development project. The negotiations really influence the performance of a company. Therefore, it isuseful to support negotiations and planning decisions with software agents. Our approach integrates software agentapproaches for negotiation support with flexible multiserver workflow engines.
