南北流量和东西流量

前言

今天在看某云产品的时候,发现一款产品名为"东西向网卡"的东西。顿时感到有点懵逼,因为没有在其他XX云中看到有这样的产品。在我的知识库中也没有存储关于这个东西的知识点,故一顿Google、Baidu。下面我们通过一张拓扑图来了解一下东西&南北向流量的意思。

拓扑图

南北流量

North-South Traffic or Communication (also, N-S, N/S, or N | S) denotes a direction of traffic flow into and out of a data center. Based on the most commonly deployed topology of systems within a data center, North-South traffic typically indicates data flow that either enters or leaves the data center from/to a system physically residing outside the data center, such as user to server. Southbound traffic is data entering the data center (through a firewall and/or other networking infrastructure); data exiting via the perimeter network devices is said to be northbound. The other direction of traffic flow is East-west traffic which typically indicates data flow within a data center.

南北流量意思就是客户端到服务器之间的通讯流量。

东西流量

East-West Traffic denotes a direction of traffic flow within a data center. Based on the most commonly deployed topology of systems within a data center, East-West traffic indicates flow of data among devices within a specific data center. The other direction of traffic flow is North-south traffic, which typically indicates data flow that either enters/leaves the data center from/to a system physically residing outside the data center.

东西流量意思就是数据中心内服务器到服务器之间的通讯流量,也叫横向流量。

东西南北

把拓扑图当成地图看,上北下南左西右东,^-^ 就这么简单。
