Abstract

This paper presents an approach for managing SLA contracts in new highly dynamic mobile Grid scenarios tackled in the Akogrimo project [1]. The problem of controlling context, negotiate and control QoS as well as undertake corrective actions is outlined. The main outcome is the validation of emerging specifications like WS-Agreement and WS-Agreement Negotiation. The purpose is to increase the technological experience of SLA contract management in Grids and propose some extensions of specifications. The paper also indicates the need to develop simplified and more flexible contract negotiation mechanisms in these environments, and the need for collocation protocols for negotiation. The lack of suitable and reliable SLA control mechanisms is slowing down the adoption of Grid technologies which provide numerous advantages such us optimal use of resources, higher flexibility and new business models in open and distributed e-business context for industry.
