Abstract
A system and method for protecting data communications in a system including a load-balancer connected to a cluster of security network components, e.g. firewall node. The load-balancer transfers one or more of the data streams respectively to the security components. The security network components transmit control information to the load-balancer and the control information includes an instruction regarding balancing load of the data streams between said components; The load-balancer balances load based on the control information. Preferably, network address translation (NAT) is performed by the load-balancer based on the control information or NAT is performed by the security network component and the control information includes information regarding an expected connection based on NAT. Preferably, when the data communications includes an encrypted session, an encrypted connection of the encrypted session is identified based on the control information and the balancing of the load maintains stickiness of said encrypted connection.
