Abstract

Many QoS constraints in network environments exists, beginning with hard real time networks on the field bus level, up to Differentiated Services or VLAN tagging for commodity computer networks. However, all these approaches are not applicable for cloud-based environments, where networks need to be configured dynamically and on-demand. In this paper, we present an approach for centralized and dynamic network configuration. We show that QoS constraints can be fulfilled by decoupling the control and datapath of packet forwarding hardware in Ethernet based interconnection networks, that are widely-used in data centers and cloud environments. Furthermore, we introduce our cloud middleware and explain the resulting problems raised by interconnecting virtualized embedded systems through overlay networks with QoS constraints coming from the field bus domain.
云环境下QoS约束网络的一种方法
网络环境中存在许多QoS约束,从现场总线级别的硬实时网络开始,一直到商用计算机网络的差异化服务或VLAN标记。但是,所有这些方法都不适用于基于云的环境,因为在这种环境中,网络需要按需动态配置。本文提出了一种集中式动态网络配置方法。在数据中心和云环境中广泛使用的基于以太网的互连网络中,通过解耦数据包转发硬件的控制和数据路径可以实现QoS约束。此外,我们还介绍了我们的云中间件,并解释了通过带有来自现场总线域的QoS约束的覆盖网络互连虚拟化嵌入式系统所产生的问题。
