2.1 flow基本概念 在网络中，流flow代表通信的对等端的一条连接。有多种方式来进行标识，在不同的应用中各不相同，通常我们关心的流记录分类依据由一个五元组（即源地址、目的地址、源端口、目的端口和协议类型）所组成。流的生命周期图如下： 图2.1 flow的生命周期 其中有几个是关键帧(包)： l 产生：当一个四元组sip sport dip dport第一次出现 l 应用识别：明确标识流承载的应用protocol l 状态：根据所承载的应用协议更新状...
小的装了flow-tools和fprobe两个软件,对我的机器作了一下测试,但是用了flow-print, flow-stat, flow-filter等命令都没有办法把ip地址对应的MAC地址找出来,由于是这方面的新手,对命令也不是太熟,故求教DX们,flow-tools能将ip地址和MAC地址对应起来吗?
Don't count on it, it's irresponsible.:) The only things that really differentiate one line card from another are the physical layer interface module (PLIM) and the Layer 3 Forwarding Engine. Each LC can be divided into three major sections: Physical Layer Interface Module (PLIM) - This is the hardware module that terminates the physical connection (media dependent; therefore, Asynchronous T...
The statements inside your source files are generally executed from top to bottom, in the order that they appear. Control flow statements, however, break up the flow of execution by employing decision making, looping, and branching, enabling your program to conditionally execute particular blocks of code. This section describes the decision-making statements (if-then, if-then-else, switch...
