Abstract

Grids rely on a complex interconnection of IP domains that may exhibit changing performance characteristics and may offer different quality of service (QoS) facilities. We examine the case of a biomedical application distributed over a grid and show how it may suffer from uncontrolled communication performance. Then we present the QoSINUS service that dynamically allocates the network resources to Grid flows in order to match their specific QoS requirements under different load conditions. The aim of this approach is to optimize the end to end performances the heterogeneous mix of grid flows gets from the network to enhance the individual application's performance as the overall grid infrastructure performance and utilization level. The QoSINUS service is based on the programmable network approach that offers flexibility, evolutivity and enables dynamic adaptation to network load variations. Finally results of QoSINUS experiments conducted in the context of the eToile french grid testbed based on the high speed and DiffServ capable research network infrastructure, VTHD, are presented.

网格环境下网络QoS的灵活动态控制:QoSINUS方法

网格依赖于IP域的复杂互连，这些IP域可能表现出不断变化的性能特征，并可能提供不同的服务质量(QoS)设施。我们研究了分布在网格上的生物医学应用程序的情况，并展示了它如何受到不受控制的通信性能的影响。在此基础上提出了QoSINUS服务，该服务可以动态地将网络资源分配给网格流，以满足网格流在不同负载条件下的特定QoS需求。该方法的目的是优化异构混合网格流从网络中获得的端到端性能，以提高单个应用程序的性能作为整体网格基础设施的性能和利用水平。QoSINUS服务基于可编程网络方法，该方法提供了灵活性、演进性，并能够动态适应网络负载变化。最后给出了基于高速差分服务研究网络基础设施(VTHD)的eToile法国网格试验台进行的QoSINUS实验结果。
