This article introduces the networking part of Elasticsearch. We look at the network topology of an Elasticsearch cluster, which connections are established between which nodes and how the different Java clients works. Finally, we look a bit closer o…

Welcome back! This time, we’ll look into what is perhaps the “poster boy” feature introduced with the D3D11 / Shader 5.x hardware generation: Tessellation. This one is interesting both because it’s a fun topic, and because it marks the first time in…

OSI模型中的各层 物理层 物理层(physical layer)协调通过物理媒体传送比特流时所需要的各种功能.物理层涉及到接口和传输媒体的机械和电器规约.它还定义了这些物理设备即接口为了实现传输必须完成的过程和功能. 物理层负责把逐个的比特从一跳(结点)移动到下一跳. 物理层关心的是以下一些内容: 接口和媒体的物理特性物理层定义了设备与传输媒体之间的接口特性.它还定义了传输媒体的类型(见后面分享). 比特的表示物理层的数据由一串没有任何解释的比特(bit)流(0和1的序列)组成.发送时,比特必…
