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： 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 network stack includes a packet loss analyzer that distinguishes between packet losses due to congestion and due to lossyness of network connections. The loss analyzer observes the packet loss patterns for comparison with a packet loss model. The packet loss model may be based on a Forward Error Correction (FEC) system. The loss analyzer determines if lost packets could have been recovered by a receiving network device, if FEC had been used. If the lost packets could have been corrected by FEC, the loss analyzer assumes that no network congestion exists and that the packet loss comes from the lossy aspects of the network, such as radio interference for wireless networks. If the loss analyzer determines that some of the lost packet could not have been recovered by the receiving network device, the loss analyzer assumes that network congestion causes these packet losses and reduces the data rate.

摘要： Network traffic information from multiple sources, at multiple time scales, and at multiple levels of detail are integrated to more easily identify relevant network information. The network monitoring system stores and manipulates low-level and higher-level network traffic data separately to enable efficient data collection and storage. Packet traffic data is collected, stored, and analyzed at multiple locations. The network monitoring locations communicate summary and aggregate data to central modules, which combine this data to provide an end-to-end description of network traffic at coarser time scales. The network monitoring system enables users to zoom in on high-level, coarse time scale network performance data to one or more lower levels of network performance data at finer time scales. When high-level network performance data of interest is selected, corresponding low-level network performance data is retrieved from the appropriate distributed network monitoring locations to provide additional detailed information.

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： 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： 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 (1400). 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 (1405). 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： 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： 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.
