    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: 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.

    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. The invention also relates to a method and apparatus for requesting data from one of a plurality of servers. An virtual network of nodes is generated in response to a data request. A first node on the virtual network of nodes is chosen randomly, and a path generated from the first node to the root on the virtual network. At least one node on the path is mapped to a respective one of the plurality of servers and data is requested from a server. The node may be mapped to the server using the method and apparatus for distributing a request to one of a plurality of resources of the present invention.
