论文摘要
网络应该为数据包提供有限的延期保证的关键属性是什么?在本文中,我们试图回答这个问题。为此,我们探讨了有限的延迟网络的理论,并提供了在网络中具有确定性有限延期所需的必要条件和足够条件。我们证明,只要网络正在进行工作支持,独立于交换机中使用的数据包调度和队列管理算法,就足够在网络边缘塑造流量〜\ textit {正确},以满足网络中的硬限制元素。使用派生的定理,我们展示了Sharpedge,这是一种新颖的设计,可满足网络中的确定性界限。据我们所知,Sharpedge是第一个可以符合以下关键属性的方案:1)它支持不同类别流量的共存,而它可以保证其不同的必要界限2)2)它不需要网络核心的任何更改,3)它支持周期性和4)网络同步设备之间的周期性和4)不需要网络的爆发方式。
What are the key properties that a network should have to provide bounded-delay guarantees for the packets? In this paper, we attempt to answer this question. To that end, we explore the theory of bounded-delay networks and provide the necessary and the sufficient conditions required to have deterministic bounded-delays in the network. We prove that as long as a network is work-conserving, independent of the packet scheduling and queue management algorithms used in the switches, it is sufficient to shape the traffic~\textit{properly} at the edge of the network to meet hard bounded-delays in the network. Using the derived theorems, we present SharpEdge, a novel design to meet deterministic bounded-delays in the network. To the best of our knowledge, SharpEdge is the first scheme that can meet all following key properties: 1) it supports coexistence of different classes of traffic, while it can guarantee their different required bounded-delays 2) it does not require any changes in the core of the network, 3) it supports both periodic and bursty traffic patterns, and 4) it does not require any time synchronization between network devices.
