Abstract
A system and method is directed to managing network communications and improving network security. In a communication protocol, an improved method of generating a value that encodes information received in an incoming message, and a corresponding way of validating an incoming message with an encoded value, improves network security. A technique for directing a network device to delay communications includes sending an instruction designating an initial window size of zero to the device. Another technique uses a TCP fast retransmit protocol. The techniques can be used to provide layer four switching, change to layer seven switching when desired, and then change back to layer four switching to improve security in a layer four switching device. Levels of trust can also be used to selectively perform aspects of the invention.
