摘要： Transactions are accelerated by the transaction handlers by storing segments of data used in the transactions in persistent segment storage accessible to the server side transaction handler and in persistent segment storage accessible to the client side transaction handler. When data is to be sent between the transaction handlers, the sending transaction handler compares the segments of the data to be sent with segments stored in its persistent segment storage and replaces segments of data with references to entries in its persistent segment storage that match or closely match the segments of data to be replaced. The receiving transaction store reconstructs the data sent by replacing segment references with corresponding segment data from its persistent segment storage.

摘要： Virtual storage arrays consolidate data storage at a data center for physical and virtual computer systems at one or more branch network locations. Standalone and virtualized computer systems at a branch network location load, execute, and store their operating systems, applications, and data using virtual storage arrays and do not require any built-in or external non-volatile data storage devices such as hard disk drives or solid-state drives at the branch network location. The virtual disks of the virtual storage array are mapped to physical data storage at the data center and accessed via a WAN using storage block-based protocols. A storage block cache at the branch network location includes storage blocks prefetched based on knowledge about the computer systems at the branch network location and the behavior of their operating systems and applications.

摘要： In a network having transaction acceleration, for an accelerated transaction, a client directs a request to a client-side transaction handler that forwards the request to a server-side transaction handler, which in turn provides the request, or a representation thereof, to a server for responding to the request. The server sends the response to the server-side transaction handler, which forwards the response to the client-side transaction handler, which in turn provides the response to the client. Transactions are accelerated by the transaction handlers by storing segments of data used in the transactions in persistent segment storage accessible to the server-side transaction handler and in persistent segment storage accessible to the client-side transaction handler. When data is to be sent between the transaction handlers, the sending transaction handler compares the segments of the data to be sent with segments stored in its persistent segment storage and replaces segments of data with references to entries in its persistent segment storage that match or closely match the segments of data to be replaced. The receiving transaction store reconstructs the data sent by replacing segment references with corresponding segment data from its persistent segment storage, requesting missing segments from the sender as needed. The transaction accelerators could handle multiple clients and/or multiple servers and the segments stored in the persistent segment stores can relate to different transactions, different clients and/or different servers. Persistent segment stores can be prepopulated with segment data from other transaction accelerators.

摘要： Proxy devices associate their direct connection with a client/server connection passing through one or more NAT devices. First proxy device receives a network connection request from a client. First proxy device stores connection information in association with a connection identifier. Connection information may reflect the usage of NAT devices between the two proxy devices. First proxy device sends a connection response including the connection identifier to the client. Second proxy device sends a direct connection request to first proxy device to establish a direct connection. Direct connection request includes the connection identifier, which is used by first proxy device to associate the direct connection with stored connection information. First proxy device may use the connection information to direct network traffic received via this direct connection to the correct destination and to divert network traffic from the server to the client through the direct connection and first and second proxy devices.

摘要： In a network supporting transactions between clients and servers and proxies that are interposable in a network path between at least one client and at least one server, wherein a pair of proxies can modify a packet stream between a client and a server such that packet data from the client to the server is transformed at a client-side proxy of the proxy pair and untransformed at a server-side proxy of proxy pair and such that packet data from the server to the client is transformed at the server-side proxy and untransformed at the client-side proxy, a method and apparatus for a discovering proxy to transparently discover its position in a proxy pair by using proxy signals to indicate to other proxies that could pair with the discovering proxy. A discovering proxy might determine that it is a client-side proxy by receipt of a packet from client without a proxy signal. A discovering proxy might determine that it is a server-side proxy by receipt of a packet from server without a return proxy signal. Once a proxy pair is discovered, that proxy pair might transform traffic from the server to the client or vice versa, transforming the traffic at one proxy of the proxy pair and untransforming the traffic at the other proxy of the pair.

摘要： In a coding system, input data within a system is encoded. The input data might include sequences of symbols that repeat in the input data or occur in other input data encoded in the system. The encoding includes determining a target segment size, determining a window size, identifying a fingerprint within a window of symbols at an offset in the input data, determining whether the offset is to be designated as a cut point and segmenting the input data as indicated by the set of cut points. For each segment so identified, the encoder determines whether the segment is to be a referenced segment or an unreferenced segment, replacing the segment data of each referenced segment with a reference label and storing a reference binding in a persistent segment store for each referenced segment, if needed. Hierarchically, the process can be repeated by grouping references into groups, replacing the grouped references with a group label, storing a binding between the grouped references and group label, if one is not already present, and repeating the process. The number of levels of hierarchy can be fixed in advanced or it can be determined from the content encoded.
