Abstract: A method and apparatus for data transmission between a sending node and a receiving node is provided. The sending node has a transmission executor for sending a decrypted message as a plurality of packets. When the encrypted message includes a message authentication code (MAC), the sending node sets an indicator in the packet that the result of MAC authentication will be sent later. The packet is sent from the sending node to the receiving node in a pipeline mode. The receiving node has buffer, and a preprocessor for preprocessing the payload of the packet. If the operation requested or the preprocessing required by the payload does not require MAC authentication, the requested operation/preprocessing will be executed. Otherwise, the receiving node defers the execution until the corresponding positive notification of MAC authentication is received from the sending node. Handling of negative MAC authentication is policy based at the receiving node.

Abstract: A method and apparatus for managing a data transmission in a network is provided, which has a client, a real server and a load-balancing node (virtual server). The load-balancing node includes a handshake executor for handling a security protocol to establish a handshake between a client and a server, and a communication executor for establishing a direct communication between the client and the server using a session information in respect to the established handshake. The handshake executor establishes the handshake with the client. When the handshake is established, the communication executor exports session information in respect to the established handshake. The client establishes TCP/IP connection with the server. The client and server communicate each other directly.
