Port reuse is a classic problem in network programming, and the knowledge points in it are very cumbersome. This paper briefly introduces so through the code_ Reuseaddr, but so will not be involved_ REUSEPORT. For a long time, we all know that we can't listen to the same port. For example, the following code. server1.listen(8080); server2.li ...

Small C/S development framework - csframework (I) First of all, it should be explained that the framework is based on a multi-level system, which has three layers - communication layer, session layer and outermost layer (server and client). Among them, the communication layer is the lowest layer, the next layer is the session layer, and finall ...

Neighbors can be simply understood as one hop distance on the third floor. The next hop of the route may not be the one hop distance of the direct connection (iterative routing), but it is the one hop distance when it finally reaches the neighbor subsystem. Usage of linux iterative Routing: https://www.jianshu.com/p/070202b6d3ca The neighbor s ...
