Round robin is a process used for network communication and operating system load balancing. A system that works in a round robin fashion distributes load based on the round robin algorithm.
The round robin algorithm uses its scheduling techniques to assign processing time slices and transfer queued data packets. Network devices such as routers and switches implement special round robin algorithm buffer queues, which exist in device memory and store incoming and overloaded data for future processing.
The term is also used in load balancing for servers. For example, a front-end load balancer on a webfarm could distribute Internet traffic among a group of webservers based on a round-robin process.
