Abstract: A 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 connection requests at the VIP by selecting one of the plurality of servers to handle that connection, wherein the selecting is based, at least in part, on a given function of information used to request the connection; and a firewall mechanism constructed and adapted to accept all requests for the VIP address for a particular connection only on the server that has been selected to handle that particular connection. The selected server determines whether it is responsible for the request and may hand it off to another cluster member.

Abstract: A load-balancing cluster includes a switch having a plurality of ports; and a plurality of servers connected to at least some of the ports, each of the servers being addressable by the same virtual Internet Protocol (VIP) address. Responsive to a connection request at the switch to connect a client computer to a server associated with the VIP address, a first server of the plurality of servers establishing a Transmission Control Protocol (TCP) connection with the client computer, and, in response to a resource request received by the first server from the client computer for a particular resource, if the first server does not have a copy of the particular resource it queries one or more peers regarding the particular resource. Based at least in part on responses from the peers, the first server either: obtains the particular resource from a first peer of the one or more peers when the first peer indicates that the first peer has a copy of the particular resource; or migrates the TCP connection to a second peer when the second peer indicates that the initial peer server should migrate the connection to the second peer; or serves the particular resource to the client request through a second server when a third peer indicates that the initial server should proxy the particular resource through the second server.
