network packet kernel rate limit

network packet kernel rate limit

[YUAN Linyu]

User space application require linux kernel to do rate limit to some type of Ethernet packet(ARP, ICMP, TCP, for example 1000 packet/s) when system run under Ethernet packet flooding test.
Do you know if kernel already exist a feature to implement this requirement?

Thanks

There are multiple Qdisc's for rate limiting, e.g.:
