摘要： In address manipulation enabled transaction accelerators, the transaction accelerators include outer connection addressing information in packets emitted over an inner connection between transaction accelerators and inner connection addressing information is added in packets sent over the inner connection. The inner connection addressing information can be carried in TCP option fields, directly in other fields, or indirectly through data structures maintained by the endpoints processing the connection. Address information can be encoded into header fields originally intended for other purposes but that are unused or encoded into used fields, overlaid in combination with other data that is being carried in those used fields. The existence of inner connection addressing information in a packet can be signaled by a flag in the packet, by a bit or other designated encoding. The flag can be in an unused header field or overlaid. Where replacement and option addition is needed, swappers and unswappers might be used.

摘要： Network devices include proxies and where multiple proxies are present on a network, they can probe to determine the existence of other proxies. Where more than two proxies are present and thus different proxy pairings are possible, the proxies are programmed to determine which proxies should form a proxy pair. Marked probe packets are used by proxies to discover each other and probing is done such a connection can be eventually formed even if some probe packets fail due to the marking. Asymmetric routing can be detected and proxies configured for connection forwarding as necessary.

摘要： Network devices include hosted virtual machines and virtual machine applications. Hosted virtual machines and their applications implement additional functions and services in network devices. Network devices include data taps for directing network traffic to hosted virtual machines and allowing hosted virtual machines to inject network traffic. Network devices include unidirectional data flow specifications, referred to as hyperswitches. Each hyperswitch is associated with a hosted virtual machine and receives network traffic received by the network device from a single direction. Each hyperswitch processes network traffic according to rules and rule criteria. A hosted virtual machine can be associated with multiple hyperswitches, thereby independently specifying the data flow of network traffic to and from the hosted virtual machine from multiple networks. The network device architecture also enables the communication of additional information between the network device and one or more virtual machine applications using an extended non-standard network protocol.

摘要： SERIAL CLUSTERING ABSTRACT OF THE DISCLOSURE Serial clustering uses two or more network devices connected in series via a local and/or wide-area network to provide additional capacity when network traffic exceeds the processing capabilities of a single network device. When a first network device reaches its capacity limit, any excess network traffic beyond that limit is passed through the first network device unchanged. A network device connected in series with the first network device intercepts and will process the excess network traffic provided that it has sufficient processing capacity. Additional network devices can process remaining network traffic in a similar manner until all of the excess network traffic has been processed or until there are no more additional network devices. Network devices may use rules to determine how to handle network traffic. Rules may be based on the attributes of received network packets, attributes of the network device, or attributes of the network.
摘要翻译：串行集群摘要串行集群使用两个或多个通过本地和/或广域网串联连接的网络设备，以便在网络流量超过单个网络设备的处理能力时提供额外的容量。当第一个网络设备达到其容量限制时，超出该限制的任何超量网络流量不变地通过第一个网络设备。与第一网络设备串联连接的网络设备将拦截并处理多余的网络流量，前提是它具有足够的处理能力。额外的网络设备可以以类似的方式处理剩余的网络流量，直到已经处理了所有超量的网络流量，或者直到没有更多的额外的网络设备。网络设备可能会使用规则来确定如何处理网络流量。规则可以基于接收的网络分组的属性，网络设备的属性或网络的属性。

摘要： Two or more network traffic processors connected with the same LAN and WAN are identified as neighbors. Neighboring network traffic processors cooperate to overcome asymmetric routing, thereby ensuring that related sequences of network traffic are processed by the same network proxy. A network proxy can be included in a network traffic processor or as a standalone unit. A network traffic processor that intercepts a new connection initiation by a client assigns a network proxy to handle all messages associated with that connection. The network traffic processor conveys connection information to neighboring network traffic processors. The neighboring network traffic processors use the connection information to redirect network traffic associated with the connection to the assigned network proxy, thereby overcoming the effects of asymmetric routing. The assigned network proxy handles redirected network traffic in much the same way that it would handle network traffic received directly.
