我检查了与桥接网络和覆盖网络相关的视频和文档,但我找不到区别.两者都用于在两个网络之间创建连接.但有什么区别呢?什么时候应该使用桥接,什么时候应该使用覆盖网络?
解决方案桥接网络连接两个网络,同时从多个通信网络或网段创建一个聚合网络,因此得名桥接.
在上图中,A 站和 B 站由一座桥相连.因此,通过使用网桥,我们将两个网络聚合在一个单元中(在高层次上).Bridge 甚至可用于在同一主机上的网络之间创建连接.如果主机运行多个虚拟机或容器,这通常是必需的.
覆盖网络通常用于在两个独立主机之间创建虚拟网络.虚拟,因为网络是建立在现有网络上的.
在上图中,主机 A 和主机 B 通过外部网络连接,并在该网络上构建覆盖网络.例如,最初互联网是作为覆盖在电话线上的方式构建的,但现在许多电话网络(使用 VoIP)都覆盖在互联网上.
I have checked videos and docs related to bridge network as well as overlay network, but I just can't find the difference. Both are used to create a connection between two networks. But what is the difference? When should I use bridge and when should I use overlay network?
解决方案Bridge networks connect two networks while creating a single aggregate network from multiple communication networks or network segments, hence the name bridge.
In the above image Station A and Station B are connected by a bridge. Thus by using the bridge we aggregated both network in a single unit (on a high level). Bridge can even be used to create connection between networks on same host. This is generally required if the host is running multiple VM's or containers.
Overlay networks are usually used to create a virtual network between two separate hosts. Virtual, since the network is build over an existing network.
In the above image host A and host B are connected over an external network and an overlay network is built over that network. For example initially internet was built as an overlay over telephone lines, but now many telephone networks (using VoIP) are an overlay over internet.
