摘要： A method and system for distributing network traffic to multiple traffic management devices. A distributor receives each packet from a network and may act as a layer 2 switch, a router, or distribute the packet to one of a group of traffic management devices. The distributor may receive packets from servers that the traffic management devices are managing communications to. When distributing packets to traffic management devices, information such as source and destination addresses may be used to determine which traffic management device each packet should be sent to. The distributor causes packets that are part of a flow to be delivered to the same traffic management device. Many configurations are possible for connecting the distributor to the traffic management devices, including connecting each traffic management device to a physical or virtual port on the distributor, connecting the traffic management devices to the distributor using a virtual local area network, and connecting the traffic management devices to a layer 2 switch.

摘要： A method and system is directed to distributing a flow of packets over a network to multiple traffic management devices. An apparatus receives each packet from a network and may act as a layer 2 switch, or router, to distribute the packet to one of a group of traffic management devices. The apparatus also may receive packets from servers for which the traffic management devices are managing communications. When distributing packets, a target traffic management device is selected from the group of traffic management devices. A connection key associated with the received packet and an identifier associated with the selected traffic management device are saved such that subsequent received packets in the flow of packets are delivered to the same traffic management device.

摘要： A system and method for performing asynchronous cryptographic operations. A cryptographic toolkit receives requests for cryptographic operations, and initiates the cryptographic operations within a thread of execution. The toolkit detects when the cryptographic operations are complete, retrieves the results, and returns the results to a calling program. The cryptographic operations are performed in an asynchronous manner, without blocking a calling program. The calling program can specify whether the requested operations are to be performed without blocking.

摘要： A method and system is directed to routing a flow of packets over a network to multiple traffic management devices. An apparatus receives each packet from a network and forwards the packet to one of a group of traffic management devices. The apparatus also may receive packets from servers for which the traffic management devices are managing communications. When forwarding packets, a traffic management device is selected from the group of traffic management devices by employing a hash of an IP address and port number. The IP address and port number are selected from source or destination information in the packet that has a greater port number. When the traffic management device performs a network address translation, further actions may be performed so that packets that are part of a flow between two network devices are delivered to the same traffic management device.
