摘要： Virtual storage arrays consolidate branch data storage at data centers connected via wide area networks. Virtual storage arrays appear to storage clients as local data storage; however, virtual storage arrays actually store data at the data center. The virtual storage arrays overcomes bandwidth and latency limitations of the wide area network by predicting and prefetching storage blocks, which are then cached at the branch location. Virtual storage arrays leverage an understanding of the semantics and structure of high-level data structures associated with storage blocks to predict which storage blocks are likely to be requested by a storage client in the near future. Virtual storage arrays determine the association between requested storage blocks and corresponding high-level data structure entities to predict additional high-level data structure entities that are likely to be accessed. From this, the virtual storage array identifies the additional storage blocks for prefetching.

摘要： Self-discovering transaction accelerators improve communications between a client and a server. A client directs a message to a server. A client-side transaction accelerator intercepts the message, terminates the connection with the client, and accelerates the request by replacing segments of data with references. The accelerated request is forwarded to a server-side transaction accelerator through a new connection. The server-side transaction accelerator reconstructs the message by replacing the reference with segment data in a persistent segment store accessible to the server-side transaction accelerator. The reconstructed request is then provided to the server. Accelerations may occur in any direction of communication. Persistent segment stores can be pre-populated with segment data from other transaction accelerators and anticipated transactions. The persistent segment store can store segments that are data segmented based on content of the data and can be independent of transaction protocol, application, and device.

摘要： A system of network proxies distributes data to multiple servers. Each network proxy is associated with a server. A network proxy intercepts a client request for data. If the network proxy determines that the request can be served using a copy of data stored on the local server, rather than the data stored on a remote server, it diverts the request to the local server. If the network proxy determines that the request cannot be served using a data from the local server, the network proxy diverts the request to a remote server storing the primary copy of the data. A server map specifies the locations of the primary copies of data. When a primary copy of data is updated on one of the servers, the associated network proxy propagates the updated data to the other servers. The servers can provide data from files, e-mail services, databases, or multimedia services.

摘要： Systems and techniques are described for optimizing communications between a client and a server. Specifically, in some embodiments, an executing script on a client can send a resource request to a server. In response, the server can send an optimized version of the resource back to the client. The client can then reconstruct the resource from the optimized version of the resource.

摘要： 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.
