The present application is directed towards systems and methods for providing user interfaces for management applications via a definition-based graphical user interface (GUI) framework for developing web based management applications for servers, intermediaries, routers, wide area network (WAN) accelerators, caches, switches, or any other type and form of computing device. The plug-in free framework reduces the server's resource consumption and bandwidth by making a full use of resources available on the client computing device or browser. A complete web application can be developed using JavaScript Object Notation (JSON) definitions along with a representational state transfer (REST) based application programming interface (API) efficiently using the framework, which may comprise light-weight pure JavaScript or similar executable code. In many embodiments, the framework may be layered in a model-view-controller (MVC) architecture easing resource consumption, maintenance and extensibility.

A method for dynamic management of Transmission Control Protocol (TCP) reassembly buffers in hardware (e.g., in a TCP / IP offload engine (TOE)). The method comprises: providing a plurality of data blocks and an indirect list; pointing, via entries in the indirect list, to allocated data blocks in the plurality of data blocks that currently store incoming data; if a free data block in the plurality of data blocks is required for the storage of incoming data, allocating the free data block for storing incoming data; and, if an allocated data block in the plurality of data blocks is no longer needed for storing incoming data, deallocating the allocated data block such that the deallocated data block becomes a free data block.

A delay measurement technique according to an embodiment according to the present invention is based on the precept, ascertained by the inventors, that a link between network nodes will often contribute to the delay encountered between several different pairs of network nodes. Such a technique identifies the path between each pair of nodes by a list of links that form the path. Paths that are orthogonal are treated as being necessary for describing the delays encountered between nodes, and, once the requisite set of orthogonal paths has been derived, all other paths can be described in terms of one or more of these orthogonal paths. Such a technique also lends itself to matrix representation of the paths, and the use of matrix manipulation techniques in deriving delay and jitter.

This invention comprises a method and system for estimating unique visitors for Internet sites that is more accurate than the existing unique cookie / unique address counting methods. The invented method relies on the count of unique user identifiers (such as network addresses or preferably cookies)—I—that can be obtained from an existing cookie tracking / user access logging system. The number of unique visitors U is calculated substantially as a ratio of the count of unique cookies (or unique network addresses) to the number of visits N times the inflation factor X plus constant on that is approximately one (exactly one in the case of cookies). The number of visits is calculated by multiplying the sampling period t to the visitation frequency T1 minus one. The resulting estimate of the unique visitors is stable and does not diverge with sampling time unlike estimates directly obtained from the unique network address or unique cookie counts. The method is also applicable when there are multiple dominant visitation frequencies by accounting to the sum by all significant visitation frequencies. All key parameters of the method can be established before hand by mining a multitude of the site's historical visit logs and / or third party site access logs; the parameters can be corrected / calculated dynamically by mining the site's current access log (or current third party logs) while focusing on unambiguously identified visitors (such as return visitors identified by their login ID or unchanged cookie value).

A database system comprises a plurality of datasets, each dataset including a plurality of data, and a plurality of database objects, each object having a security label comprising a security classification of the object, at least one database session, the database session having a security label indicating a security classification of the database session, wherein, the database system is operable to allow or deny access to data to a database session based on a security label of a database object and on a security label of the database session.

A generalized framework is disclosed in which a wide variety of propagation models can be cast in a matrix-based format using arbitrary matrix coefficients. Casting propagation models in the matrix-based framework enables efficient computer implementation and calculation, ease of tuning, admissibility, and aggregating multiple propagation models into a single matrix-based model. Matrix-based propagation models based on transmitter-receiver azimuth orientation, transmitter antenna height, terrain elevation, and clutter are also disclosed. The propagation models can be used in conjunction with automated data acquisition from information sources such as topographic maps, clutter maps, etc.

A method of operating a fault tolerant connection in a network is described. The network includes a number of network elements and a number of links. Each of the network elements is coupled to at least one other of the network elements by at least one of the links. The method identifies a first path and a second path. The first path is between a first one of the network elements and a second one of the network elements, as is the second path. Moreover, the first path and the second path are disjoint. This disjointedness can be any difference between the two paths (e.g., any combination of different network elements or links). A packet is sent from the first one of the network elements via the first path, while a duplicate packet is sent from the first one of the network elements via the second path. The duplicate packet is a duplicate of the packet. Once these packets have been sent, at least one of the packet and the duplicate packet are received at the second one of the network elements. If both the packet and the duplicate packet are received at the second one of the network elements, one of the two is discarded (e.g., by simply ignoring the last one received).

A low-cost high-speed programmable rasterizer accepting an input set of functionals representing a triangle, clipping planes and a scissoring box, and producing multiple spans per clock cycle as output. A Loader converts the input set from a general form to a special case form accepted by a set of Edge Generators, the restricted input format accepted by the Edge Generators contributing to their efficient hardware implementation.

A hash function for a MAC bridge filter that improves bridge performance by reducing overflow of the MAC bridge database and which reduces cost of the device by using relatively few hardware resources. A CRC hash function is used to randomize the search string in the MAC bridge filter so that a consistent bridge performance is achieved regardless of where the bridge is used. Using the CRC as a hash function also results in efficient hardware implementation. In addition, the present invention may be generalized to use a CRC-M as hash function for any bridge filter design.
