A typical task of a grid level scheduling service is the orche stration and coordination resources in grid. Especially co-allocation makes high demands on this service. Co-allocation requires scheduler to coordinate resource management systems located different domains. Provided that site autonomy has be respected negotiation only way achieve intended coordination. Today, it common practice do by using web technologies. Furthermore, agreements (SLAs) emerged as new manage usage are already adopted number systems. Therefore, natural look for ways adopt SLAs scheduling. In order this, efficient flexible protocols needed, which support dynamic creation SLAs. paper we propose discuss extensions WS-Agreement protocol addressing these issues.
