Abstract
An exemplary method for load balancing includes accessing a range of values for IP addresses associated with a virtual IP address associated with a domain name; selecting, using a local statistical algorithm, a value in the range; and, based at least in part on the selected value, connecting to a remote resource at one of the IP addresses. In such a method, a client can perform local load balancing when connecting to one of many fungible resources “behind” a virtual IP address. With many such clients, the task of load balancing is distributed as opposed to being centralized at a server farm or cluster. Other methods, devices and systems are also disclosed.
