    摘要: To serve content through a content delivery network (CDN), the CDN must have some information about the identity, characteristics and state of its target objects. Such additional information is provided in the form of object metadata, which according to the invention can be located in the request string itself, in the response headers from the origin server, in a metadata configuration file distributed to CDN servers, or in a per-customer metadata configuration file. CDN content servers execute a request identification and parsing process to locate object metadata and to handle the request in accordance therewith. Where different types of metadata exist for a particular object, metadata in a configuration file is overridden by metadata in a response header or request string, with metadata in the request string taking precedence.

    摘要: The invention relates to a method and apparatus for distributing a request to one of a plurality of resources. A request is mapped to a location in mathematical mapping space. Each of the plurality of resources is mapped to a respective location or locations in the mathematical mapping space. The request is allocated to one of the resources based on a mathematical relationship between the request location and the resource location in the mathematical mapping space. An apparatus for distributing a request to one of a plurality of resources includes the plurality of resources and an input receiving a resource request. A mapper in communication with the input maps the request to a request location in a mathematical mapping space and maps each of the plurality of resources to at least one resource locations in the mathematical mapping space. A distributor distributes the request to one of the plurality of resources in response to a mathematical relationship between the locations of the request and resources in the mathematical mapping space.

    摘要: Scatter-Gather is a computer based document browsing method which operates in time proportional to a number of documents in a target corpus. The Scatter-Gather method includes: preparing an initial ordering of the corpus using, for example, an off-line computational method; determining a summary of the initial ordering of the corpus for interactive utility; and providing a further ordering of the corpus using, for example, an on-line non-deterministic method. The step of an off-line preparation of an initial ordering of a corpus is non-time-dependent, thus an accurate initial ordering is prepared. The step of determining a summary includes determining a summary for presentation to a user without scrolling on a CRT. The step of providing a further ordering includes truncated group average agglomerate clustering, merging disjointed document sets, center finding, assign-to-nearest and other refinement methods.

    摘要: A network and a method for transmitting processes in a network are disclosed, where a randomized coding approach is provided. Network nodes transmit on each outgoing link a linear combination of incoming signals, specified by independently and randomly chosen code coefficients from a finite field. The approach allows robust, distributed transmission and compression of information in networks and is advantageous over routing-based approaches.
