Abstract: A load balancer, comprising a network interface, a power conservation unit, and a routing module configured to route client requests received through the network interface to a plurality of servers. The power conservation unit is characterized by having a learning mode and a routing mode. In the learning mode one or more operation parameters of the servers are determined for a plurality of different external conditions and for a plurality of different values of one or more operation parameters of the routing module, and to generate a correlation table between the operation parameters of the routing module and the external conditions. In the routing mode the power conservation unit adjusts the operation parameters of the routing module responsive to the external conditions, using the correlation table.

Abstract: A method for managing connections between at least one client and at least one data server, said method comprises: (a) providing an intermediary connection apparatus comprising connections to a plurality of clients over a WAN or a LAN environment, said apparatus comprising memory buffers and at least one connection to each of said at least one data server(s) being continuously open; (b) establishing a client network connection between said apparatus and one of said clients via a network; (c) receiving a client request to receive a response from a data server over said client network connection; (d) forwarding to the data server either a request or a partial request; (e) limiting the size of the response or partial response that the server is allowed to provide at a given time to said apparatus in response to said client request; and (f) buffering data encoding requests and responses in said apparatus according to data traffic load over the connection to said server and to said client, respectively.
