Load balancing service

Abstract

A load balancing service for a plurality of customers performs load balancing among a plurality of customer Web servers. Requests for Web content are load balanced across the customer Web servers. The load balancing service provider charges a fee to the customers for the load balancing service. A caching service is also provided that comprises a plurality of caching servers connected to a network. The caching servers host customer content that can be cached and stored, e.g., images, video, text, and / or software. The caching servers respond to requests for Web content from clients. The load balancing service provider charges a fee to the customers for the Web caching service

AI Technical Summary

Benefits of technology

"The invention provides a load balancing service and a caching service for multiple customers. The load balancing service uses DNS servers to effectively distribute requests for web content among multiple customer web servers. The caching service stores customer content that can be quickly retrieved by clients. The load balancing service selects the appropriate caching server based on performance metrics and charges customers for the service. The invention also provides a configuration file system for easy configuration of caching servers and allows system administrators to push new configuration files at any time. The technical effects of the invention include improved load balancing and caching performance, reduced latency and persistence information, and improved network efficiency."

Problems solved by technology

It is an extremely diffuse and complex system over where no single entity has complete authority or control.

Like automobiles during “rush hour” on Highway 101 in Silicon Valley, the tiny packets of information traveling through the Internet become congested.

Here, traffic jams which cause a delay in the information from the server to the client occur during high usage hours on the Internet.

These traffic jams lead to long wait times at the client location.

Here, a user of the client computer may wait for a long time for a graphical object to load onto his / her computer.
