使用NetFlow的网络拥塞控制

Network congestion control using NetFlow

Maxim A. Kolosovskiy, Elena N. Kryuchkova

摘要:

拥塞控制的目标是避免网络元件中的拥塞。如果向网络元件提供的流量超过其可处理的流量,则网络元件拥塞。为了检测这种情况并消除它们,我们应该监控网络中的流量。在本文中,我们建议使用思科的NetFlow技术,它允许通过生成特殊的NetFlow数据包来收集有关网络中流量的统计信息。思科的路由器可以将NetFlow数据包发送到特殊节点,因此我们可以收集这些数据包,分析其内容并检测网络拥塞。我们以Cisco的功能为例,其他一些供应商(Juniper,3COM,Alcatel等)为他们的路由器提供类似的功能。我们还考虑了一个简单的系统,它收集有关网络元素的统计信息,确定过载的元素,并确定流,拥塞它们。

英文摘要:

The goal of congestion control is to avoid congestion in network elements. A network element is congested if it is being offered more traffic than it can process. To detect such situations and to neutralize them we should monitor traffic in the network. In this paper, we propose using Cisco's NetFlow technology, which allows collecting statistics about traffic in the network by generating special NetFlow packets. Cisco's routers can send NetFlow packets to a special node, so we can collect these packets, analyze its content and detect network congestion. We use Cisco's feature as example, some other vendors (Juniper, 3COM, Alcatel, etc.) provide similar features for their routers. We also consider a simple system, which collects statistical information about network elements, determines overloaded elements and identifies flows, which congest them.
