摘要： Shift-varying segmentation uses a shift-varying predicate function to evaluate input data within a sliding window to determine if the current sliding window position should be a segment boundary. The shift-varying predicate function is a function of both the input data within the sliding window and the position of the sliding window relative to a previous segment boundary or the beginning of the input data. The shift-varying predicate function includes a containment property and may compute a hash value from the input data in the sliding window. The hash value is compared to a threshold value that is a function of the sliding window position. As the sliding window position advances away from a previous segment boundary, the probability of a segment boundary at the window position increases. Shift-varying segmentation can be used in compression, transaction acceleration, and data storage applications.

摘要： Methods, systems, and apparatus provide efficient and flexible networking quality of service as well as transport protocol design. A hybrid transport/network quality of service (HNTQ) scheme improves the performance of TCP over specific links or network paths that are subject to high latency, a high bandwidth-delay product, high packet loss, and/or bit errors. A callback mechanism can be used between a packet scheduler and a transport module to control the transmission rate of packets across one or more connections or links.

摘要： A method for configuring service curves for managing the output port of a networking device includes the following steps. A multitude of traffic classes is defined, each traffic class being characterized by a bandwidth and a delay priority. A multitude of traffic service curves is computed, each of the plurality of traffic service curves is associated with a different one of the multitude of traffic classes. At least one of the multitude of traffic classes service curves is characterized by a shifted two-piece linear function shifted such that the service curve limits service to during a nonzero time period prior to the start of the two-piece linear function.

摘要： A virtualization system provides virtualized servers at a branch network location. Virtualized servers are implemented using virtual machine applications within the virtualization system. Data storage for the virtualized servers, including storage of the virtual machine files, is consolidated at a data center network location. The virtual disks of the virtualized servers are mapped to physical data storage at the data center and accessed via a WAN using storage block-based protocols. The virtualization system accesses a storage block cache at the branch network location that includes storage blocks prefetched based on knowledge about the virtualized servers. The virtualization system can include a virtual LAN directing network traffic between the WAN, the virtualized servers, and branch location clients. The virtualized servers, virtual LAN, and virtual disk mapping can be configured remotely via a management application. The management application may use templates to create multiple instances of common branch location configurations.

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： 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： 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.

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： In a network supporting transactions between clients and servers over a network path having operating characteristics to overcome, data is transported to overcome the operating characteristics using user affinities and dynamic user location information to selectively preload data, or representations, signatures, segments, etc. of data, in order to overcome the one or more operating characteristic. Examples of operating characteristics to overcome include bandwidth limitations, errors and latency. The dynamic location information can be stored in data structures accessible by agents of a data server and the data structures are populated based on user activities with respect to proxies associated with user locations, or the dynamic location information can be obtained implicitly as proxies maintain connections after termination by clients and the use of those maintained connections for preloading of data for the users associated with those clients. The data being preloaded can be protocol-specific data or protocol-independent data.
