Abstract: The present invention presents methods and apparatus supporting acceleration of networked applications by means of dynamic distributed execution and maintenance. It also enables management and administration of the distributed components of the networked applications from a responsible point of origination. The method and apparatus deploys a plurality of proxy servers within the network. Clients are directed to one of the proxy servers using wide area load balancing techniques. The proxy servers download programs from backend servers and cache them in a local store. These programs, in conjunction with data stored at cached servers, are used to execute applications at the proxy server, eliminating the need for a client to communicate to a backend server to execute a networked application.

Abstract: This invention provides methods and apparatus for enabling access to restricted information contained at a semi-trusted web-server. Restricted information is information that is only available to a selected group of authorized clients. A client desiring access to the restricted information authenticates itself with a trusted web-server, and obtains a client credential. The client then contacts the semi-trusted web-server with the credential and obtains access to the restricted content. The restricted information may be encrypted at the semi-trusted web-server, so that the restricted information is secure even if the semi-trusted web-server is not completely secure.

Abstract: The present invention relates to a novel nitrile glycoside of Formula I named NIAZIRIDIN and to analogues and derivatives thereof. The present invention also relates to a process for the isolation of a novel nitrile glycoside of Formula I below named NIAZIRIDIN and its derivatives and analogues by bioactivity-guided fractionation from the pods of Moringa oleifera. The present invention particularly relates to the bioenhancing activity of the novel nitrile glycoside of Formula I below named NIAZIRIDIN and its derivatives and analogues in enhancing bioactivity of commonly used antibiotics such as rifampicin, tetracycline and ampicillin against Gram (+) and (?) bacteria. The biomolecule also enhances the absorption of drugs, vitamins and nutrients through the gastro-intestinal membrane increasing their bio-availability. Therefore niaziridin can be used in combination therapy with drugs and nutrients resulting in reduced drug associated toxicity, reduced cost and duration of chemotherapy.

Abstract: This invention provides methods and apparatus for validating that transformations that are expected to occur in an IP network are indeed occurring as expected. Generally, these transformations establish logical communication tunnels within an IP network between the devices that perform the transformation and the devices that perform the reverse transformation. The invention is useful to validate the configuration of devices that support a variety of IP transformation methods, including IP-security protocols using the standard Encrypted Secure Payload protocol and Authenticated Header protocols as defined by the IETF. The invention is particularly useful to validate cases in which transformations occur on the full path of a packet traversing between two machines in an IP network, or when the transformations only occur on part of this path.

Abstract: The present invention relates to the new use of an already known biomolecule methyl-&bgr;-orcinol carboxylate of formula 1 isolated from a lichen (Everniastrum cirrhatum), for treating pathogenic fungal infections of humans that are resistant to polyene and azole antibiotics such as amphotericin B, nystatin, clotrimazole etc.

Abstract: The present invention presents methods and apparatus supporting traffic engineering in a connectionless protocol network constituted by a core of plain routers, without dependencies on the underlying link protocol. The IP is used as an example of a connectionless protocol. It also enables a network operator to perform traffic engineering on a core network of plain routers supporting any connectionless protocol.

Abstract: A policy enabled caching system based upon policy rules which define whether a request from a client is directed to a cache or a server. The client is coupled to a plurality of caches and to at least one server. The caches may store a subset of the data stored on the server. The policy enabled caching system stores policy rules which comprise at least one matching condition, where every request containing a matching condition falls into an associated class. Each class will have an associated routing rule, where a routing rule defines the type of routing for all the requests which fall into that class. The policy enabled caching system will receive the request from the client and classify the request according to the policy rules. The request is then routed according to the routing rule associated with the class to which the request belongs.

Abstract: This invention provides methods and apparatus which provide a solution to the problem of server load balancing. Log files are collected from each server within a server cluster. The log files are analysed by the monitoring process to find file relations. The analysis uses a window to search for requests such that a file relation is established. Other techniques are described to establish file relations. Based on file relations files are merged into groups such that these groups of files can be distributed to N servers within a server cluster. The file merging process continues until there are N groups corresponding to the N servers. The files for each group are either distributed to each server, or all files are distributed to all servers and each server activates only the subset which comprises the group of files for that server.

Abstract: A method, system and product for resource constrained network elements to validate a set of records in a network repository by verifying validation information stored in the repository by a record validator. A record validator with adequate computational resources validates one or more set of records in a repository such a network directory, and stores validation information records in the repository. The resource-constrained network elements run simple checks to verify the validation information records thus stored. The validation information records may include the modification or creation time of validated records in the repository. The network elements compare the time stored in the validation information records to the actual modification or creation time of records to verify validity information. Cryptographic signature for enhanced security, and validation status records may be used to ensure fault-tolerant behavior.

Abstract: A method of controlling packet traffic in an IP network of originating, receiving and intermediate nodes to meet performance objectives established by service level agreements. Traffic statistics and performance data such as delay and loss rates relating to traffic flows are collected at intermediate nodes. A control server processes the collected data to determines data flow rates for different priorities of traffic. A static directory node is used to look up inter-node connections and determine initial traffic classes corresponding to those connections. The rates are combined with the initial traffic classes to define codes for encoding the headers of packets to determine their network priority.
