Linux TC ifb principle and ingress flow control, ifbingress
First, paste the annotation of the ifb. c file header of the Linux kernel:
The purpose of this driver is to provide a device that allowsFor sharing of resources:1) qdiscs/policies that are per device as opposed to system wide.Ifb allows for a device which can be redirected to thus providingAn impression of sharing.2) Allows for queueing incoming t
limitations of the TC itself, in fact, you can fully implement a queue mechanism on the Ingress point, said TC control is not controlled only because the Linux The current implementation of TC does not implement the ingress queue.Linux has a lot of hooks on the stack, NetFilter of course is the most obvious, it can not only implement firewalls and NAT, can also be a packet on the prerouting Hook point queu
Nginx limits the number of IP concurrency, which is also the limit of the same IP to connect to the server at the same time. How can Nginx limit the number of connections to the same IP, limit the number of concurrent, limit traffic/limit bandwidth? By using the Nginx module below, we can set the number of concurrent links to exceed our settings and will return 5

This thought that the effective control on the same day on the same IP only once the scheme can effectively prevent users to refresh the address of the phenomenon of cheating, I have to admit that the inexperienced--and have been ignoring the current brush flow software s

In Linux systems, it is sometimes necessary to modify the IP address of the network card. In many cases, our maintenance of the Linux system is managed remotely (SSH), so that when the IP address changes, the connection between us and the server will be disconnected.One might say that we can connect the modified IP address again, because the
