Abstract
A load-aware load-balancing cluster includes a switch having a plurality of ports; and a plurality of servers connected to at least some of the plurality of ports of the switch. Each server is addressable by the same virtual Internet Protocol (VIP) address. Each server in the cluster has a mechanism constructed and adapted to respond to determine the particular server's own measured load; convert the particular server's own measured load to a corresponding own particular load category of a plurality of load categories; provide the particular server's own particular load category to other servers of the plurality of servers; obtain load category information from other servers of the plurality of servers; and maintain, as an indication of server load of each of the plurality of servers, the particular server's own particular load category and the load category information from the other servers.
