摘要:
The present invention discloses a data structure which, given an identifier for a Representational State Transfer (REST) resource, can rapidly yield a configured target and simultaneously yield all configured pattern based rules and constraints for the target. The disclosed data structure is a tree structure including nodes for URL portions. Each node is associated with a hash tree specifically grown in a manner that ensures collision occurrences are non-existent. The tree structure is effectively two or more superimposed trees; one for URL pattern matching to determine a target, another for determining constraints. A single tree traversal, which can be based on a progressive hash, can be used to concurrently determine a target and a set of constraints, which represents improved performance over conventional implementations that require multiple, distinct query/response operations to produce equivalent results.

Disclosed herein is a method and apparatus of immobilizing a biocatalyst on a microfluidic biochip for conducting reactions in the presence of electroosmotic flow. The biochip includes a polymer on its microfluidic flow surfaces, wherein the polymer includes a first substituent selected from ionic groups of the same polarity or precursors thereof, a second substituent that is a hydrophobic group, and a third substituent comprising an immobilized biocatalyst-or precursor thereof. The biochip can be used to conduct multiple sequential biocatalyzed reactions in the presence of electroosmotic flow.

A Fragment Aggregator utilizes an application independent surrogate to dispatch fragments and receive responses between isolated web applications. Clients send web application requests to the surrogate, which forwards the request to an isolated web application. When a web application requires other isolated web applications to execute the request, the web application responds to the request with a deferred response. The deferred response includes request fragments for the other isolated web applications. The Fragment Aggregator dispatches the fragments to the other isolated web applications. After receiving responses from the isolated web applications, the Fragment Aggregator combines the response and sends them to the client.

Embodiments of the present invention address deficiencies of the art in respect to edgified content delivery and provide a method, system and computer program product for dispatching of request fragments from a response aggregating surrogate. In one embodiment, an edgified content distribution data processing system can include an origin server configured to server markup specified pages formed from dynamically arranged fragments and a surrogate server communicatively linked to the origin server over a computer communications network and acting as a surrogate at an edge of the network on behalf of the origin server. A dependency engine can be coupled to the surrogate server and can include program code enabled to group the fragments according to interdependencies among the fragments and to load fragment groups in sequence to satisfy the interdependencies.

A system and method for searching a bytestream or other string in a case insensitive manner. In a preferred embodiment, the present invention includes an ASCII tree that associated both upper and lower case letters of an incoming header key (or other symbols) with nodes. When enough nodes are gathered, a target word is found.

A method is disclosed for designing a signaling network of call coordinators (CCs) for internet telephony. The new method can be used to design a CC network of arbitrary size that satisfies, with high probability, limitations on the maximum number of sockets per CC and on the maximum number of hops between an arbitrary pair of switches in the network. According to the disclosed method, the network of CCs is treated initially as a collection of isolated points, one point for each CC. Then, links are added between pairs of CCs, excluding pairs lying within the same switch. The links are added randomly, but with a particular probability p, which may be different for different pairs. Thus, whether a given link is added depends, in effect, upon the outcome of a loaded coin toss in which the probability of a positive outcome is p.

Session state affinity is maintained in a workload balancing system that includes a hypertext transfer protocol (HTTP) routing server and a plurality of application servers. The application servers maintain backup session state information for a first session to a first server of the plurality of application servers at fewer than all of the plurality of application servers, detect the unavailability of the first application server at an application server of the plurality of application servers other than the first application and determine a second server that continues the first session. An identification of the second server and the first session is sent from an application server of the plurality of application servers to a HTTP routing server responsive to detecting the unavailability of the first server. The identification of the second server and the first session is received at the HTTP routing server and communications associated with the first session are routed from the HTTP routing server to the second server responsive to receiving the identification of the second server so that backup session state information maintained at the second server is used to continue the first session from the first server at the second server.
摘要:
A mechanism by which URLs are progressively hashed character by character and clauses of the URL are used to traverse a tree data structure for matching of the URL to resources/rules is provided. The hash code for a single character is appended to a prior hash code for a preceding character in the URL portion. At the time that the entire portion of the URL is hashed, as determined based on the presence of a delimiter character, the particular node in a tree data structure associated with the resulting hash code is identifiable within a hash table of a current node of the tree data structure. Each node in the tree data structure includes a multidimensional hash table for a portion of a URL. The multidimensional hash table is established and grown in a manner that ensures there are no hash collisions. Each portion of the URL is parsed in this manner and the tree data structure is traversed as each portion is processed until the entire URL is parsed at which time the resulting rules/resources may be identified from the leaf nodes of the tree data structure.
