Abstract
An address of a server that should supply an information object or service to a requester is returned in response to a request therefor. The address of the server that is returned is an optimal server selected according to specified performance metrics. The specified performance metrics may include one or more of an average delay from the server to another, average processing delays at the server, reliability of a path from the server to another, available bandwidth in said path, and loads on the server.
Claims28
A method, comprising:
- returning, in response to a request from a client, an address of a first server that should service a second server's request for an information object based on the second server receiving the client's request of the information object that is not located at the second server, the address of the first server being selected according to specified performance metrics, wherein the specified performance metrics comprise average processing delays at the first server, average delay from the first server to the second server, reliability of a path from the first server to the second server, and available bandwidth in said path from the first server to the second server;
- referring the second server's request for the information object to a first Web router;
- and
- configuring the first Web router to create a map that associates an identifier of the information object with the address of the first server according to other mappings generated by other Web routers and forwarded to the first Web router, wherein the other mappings generated by the other Web routers are forwarded to the first Web router as inter-Web router communication messages passed between the Web routers using a Web Information Locator by Distance (WILD) protocol.
1 more element
A communication system, comprising:
- one or more messages passed between Web routers over a Web information locator by distance (WILD) protocol, used for inter-Web router communication, said messages including information which allows said web routers to dynamically update mappings of information objects to server addresses including an address of a first server that should service a second server's request for an information object in response to the second server receiving a client requestor's request for an information object that is not located at the second server based on specified performance metrics, wherein the specified performance metrics comprise an average processing delay at the first server, average delay from the first server to the second server, reliability of a path from the first server to the second server, and available bandwidth in said path from the first server to the second server;
- and
- a first web router, comprising a general purpose computer, for receiving the second server's request for the information object, wherein the first web router is configured to create a map that associates an identifier of the information object with the address of the first server according to other mappings generated by other web routers and forwarded to the first web router, wherein the other mappings generated by the other Web routers are forwarded to the first Web router as inter web router communication messages passed between the web routers using a Web information locator by distance (WILD) protocol.
A method, comprising
- mapping an address of a requesting server seeking an information object to an address of an information object repository that has a best distance to the requesting server based on the requesting server receiving a requestor' s request of the information object that is not located at the requesting server according to specified performance metrics, wherein the specified performance metrics comprise average processing delays at the requesting server, average delay from one information object repository to another within a network, reliability of a path from one information object repository to another, and available bandwidth in said path;
- and
- referring the requesting server's request for the information object to a first Web router;
- and
- configuring the first Web router to create a map that associates an identifier of the information object with the address of the information object repository according to other mappings generated by other Web routers and forwarded to the first Web router, wherein the other mappings generated by the other Web routers are forwarded to the first Web router as inter-Web router communication messages passed between the Web routers using a Web Information Locator by Distance (WILD) protocol.
