Figure 1: Low latency software defined networking control loop The articles SDN and delay and delay and stability describe the critical importance of low measurement delay in CONSTRUCTI Ng stable and effective controls. This article would examine the difference in measurement latency between SFlow and Netflow/ipfix and their relative Suitabi Lity for driving control decisions. Figure 2: sFlow and NetFlow agent architectures Figure 2 illustrates shows
First, Ipfix and NetFlowFirst, IPFIXThe full name IP flow information export, namely the IP stream information output, is the international standard of network traffic monitoring. Ipfix is a working group of the IETF, whose main task is to develop a standard protocol for measuring flow information in IP networks, called the Ipfix protocol. Because of the IETF's a
Collector IntroductionJava8 's stream API makes it easy for us to classify data, and the style of functional programming allows us to write statistical code conveniently and intuitively.For example:stream1, itemitem+2). Limit (6);Stream.filter(Item-Item >2).Maptoint(Item, Item *2).Skip(2).Limit(2).Sum();//.Reduce(0, (Val, val2)->val+val2);//system. Out. println (sum); summarystatistics = stream.filter (item-item > 2). Maptoint2). Skip2). Summarysta

Preface:
In the game, we often see that after scores are obtained, the scores are automatically raised to the corresponding score bar. Today we will achieve this effect.
Body:
This effect is actually very simple. You only need to add an action to the generated score (usually a Sprite or Node) so that it can be moved to the target positi

Java8 Stream API can be very convenient for us to statistical classification of data, etc., before we write a lot of statistical data code is often iterative, not to say that others do not understand, their code for a long time also need to look back a while to understand. Now, Java8 absorbs the new features of the language for scientific computing and provides the stream API, which makes it possible to write statistical code conveniently and intuitively.There is a collect (
