"Flow switching works fairly well for fairly large demand - if you have users who need a lot of bandwidth and want low delay through the network," Gerstel says.

“流交换技术在需求很大的情况下非常适用——如果你有需要大量带宽和低网络延迟的用户群的话，”格斯特尔说。

In a Stupid Network, if you have congestion, you just add more connections, bandwidth, switching or processing power.

在愚钝网络上，如果你有新应用，你只需要添加更多的连接、带宽、交换机或处理能力。

The switching solution should have as a minimum the bandwidth of the DUT, and preferably equal to the bandwidth of any higher frequency source and measurement equipment.

切换方案的最小带宽应该为DUT的带宽，最好是等于任何高频源和测量设备的带宽。

It will all be possible because of sophisticated networks, powerful computing, low cost bandwidth terrestrial integration, and seamless switching.

Software-defined networks will provide some of this flexibility by separating the control function from data forwarding, but there are additional capabilities emerging, he says, such as intelligent switching of wavelengths, the ability to mix dedicated bandwidth with best-efforts networks, and application layer network traffic optimization, e.g.

This provides a means of switching a signal between two wavelengths a neat trick for using bandwidth more effectively.
