Introduction

DNS load balancing is to distribute requests to different servers though resolving the domain name to different IP addresses of servers. When a DNS request comes to the DNS server to resolve the domain name, it gives out one of the server IP addresses based on scheduling strategies, such as simple round-robin scheduling or geographical scheduling. This redirects the request to one of the servers in a server group. Once the domain is resolved to one of the servers in specified time-to-live, subsequent requests from the clients using the same local caching DNS server are sent to the same server.
