System-side timers can be built in eight different ways — from hardware interrupts and OS APIs to timer wheels, heaps, and event loops. This article breaks down each approach and explains why timer wheels and event-loop-integrated timers (like libevent or epoll/timerfd) are the go-to choices for production networking software handling thousands of concurrent sessions, such as BGP or tunnel keepalives.
