To keep the TCP/IP stack from taking all resources on the computer, there are different parameters that control how many connections it can handle. If running applications that are constantly opening and closing connections (P2P), or are providing a…

dfs.datanode.max.transfer.threads: 默认 4096 < 2.0之前该参数为dfs.datanode.max.xcievers >解释:Specifies the maximum number of threads to use for transferring data in and out of the DN. 表示datanode上负责进行文件操作的线程数.如果需要处理的文件过多,而这个参数设置得过低就会有一部分文件处理不过来,就会报异常.linux系统中…

Apache的HttpComponent组件,用的人不在少数.但是能用好的人,却微乎其微,为什么?很简单,TCP里面的细节实现不是每个人都能捕获到的(细节是魔鬼),像并发请求控制&资源释放,Nagle算法参数优化,Connection eviction,跟ulimit配对的total connection,重定向策略定制化,两类超时时间的合理设置,流读写等等. 在最近的项目中,更是破天荒的遇到了close_wait问题,所以利用业余时间索性将之前同学写的HttpClient优化了一遍.下面我将贴…

2010年IEEE Secon的一篇文章.当然了,应该是之前就写好了,发表过,还是直接投到Secon了呢?直接投的吧,Secon不接受已发表过的吧. 本文的着笔点:有线网与DSAN(启用了DSA特性的WLAN)集成的情况下的TCP性能研究.就是DSAN网与传统网路通信时,其整体的TCP性能研究.场景就是“最后一英里”,典型的可以想象的是,家里的光纤到户,连一个BS,然后呢,所有的手机.PAD.Laptop等终端都通过BS上网.而这部分无线节点都启用了DSA特性,那这就是一个典型的本文要研究的一个…

question: The way I understand this, there are 2 ways to close TCP connection: send FIN flag send RST flag RST causes immediate connection termination, while in FIN you get a confirmation. Do I understand this right, and are there any other distincti…

Cilium架构 译自:http://docs.cilium.io/en/stable/architecture/ 本文档描述了Cilium的架构.它通过记录BPF数据路径(datapath)的钩子来实现Cilium数据路径,那么Cilium数据路径是如何与容器编排层继承,以及如何在各层(如BPF数据路径和Cilium代理)之间更新对象的? 数据路径 Linux内核在网络栈中支持一个BPF钩子集,使用这些勾子可以允许BPF程序(即使用回调函数运行).Cilium数据路径使用这些钩子加载BPF程序…
