Abstract

A distributed streaming internet server system with multiple layers of servers, featuring data caching, file storage, and application servers. The system provides high reliability and high quality streaming media. The system is designed to be scalable so that additional capacity can be added easily as needed. Existing capacity use is optimized through reallocating user connections as necessary for load-balancing and failure management.

Claims

1. An internet service system comprising:

a primary server for managing a plurality of application servers;

a network for coupling the plurality of application servers to the primary server;

a server software program running on the primary server for detecting availability and resource usage on the plurality of application servers;

an application software program running on each application server of the plurality of application servers to report resource usage and availability to the server software program; and

a plurality of user computers coupled to the plurality of application servers by the network, said plurality of user computers sending a plurality of data requests through the network and receiving a plurality of response data.

2. The internet service system of claim 1 further comprising a media server coupled to the primary server and the application servers by the network, said media server comprising:

a data caching software program for analyzing the plurality of data requests and caching a subset of the plurality of response data; and

at least one data storage device for caching the subset of the plurality of response data.

3. The internet service system of claim 1, each application server further comprising:

a user data management software program for storing user data; and

at least one data storage device for storing the user data.

4. The internet service system of claim 1, the server software program further comprising:

a resource allocation module for collecting a resource usage data from the plurality of application servers, said resource usage data comprising at least a CPU usage percentage, a network usage percentage, and an availability indicator; and

a connection transfer module for transferring a user computer connection from a first application server of the plurality of application servers to a second application server of the plurality of application servers when the resource allocation module determines that the resource usage data from the first application server exceeds a threshold.

5. The internet service system of claim 1 further comprising a streaming management software program running on each application server of the plurality of application servers and on the media server, said streaming management software program comprising:

an input module to accept a streaming media data stream as input;

a buffering module to manage buffering levels of the streaming media data stream;

a caching module to determine whether the streaming media data stream should be cached; and

a storage module to store the streaming media data stream on the storage unit of the media server.

6. An internet service system comprising:

a plurality of servers comprising a primary server, a plurality of media servers, and a plurality of application servers;

a network for coupling the plurality of servers;

a server software program running on the primary server for detecting availability and resource usage on the plurality of application servers;

an application software program running on each application server of the plurality of application servers to report resource usage and availability to the server software program; and

a plurality of user computers coupled to the plurality of application servers by the network, said plurality of user computers sending a plurality of data requests through the network and receiving a plurality of response data.

7. The internet service system of claim 6 further comprising a media server coupled to the primary server and the application servers by the network, said media server comprising:

a data caching software program for analyzing the plurality of data requests and caching a subset of the plurality of response data; and

at least one data storage device for caching the subset of the plurality of response data.

8. The internet service system of claim 6, each application server further comprising:

a user data management software program for storing user data; and

at least one data storage device for storing the user data.

9. The internet service system of claim 6, server software program further comprising:

a resource allocation module for collecting a resource usage data from the plurality of application servers, said resource usage data comprising at least a CPU usage percentage, a network usage percentage, and an availability indicator; and

a connection transfer module for transferring a user computer connection from a first application server of the plurality of application servers to a second application server of the plurality of application servers when the resource allocation module determines that the resource usage data from the first application server exceeds a threshold.

10. The internet service system of claim 6 further comprising a streaming management software program running on each application server of the plurality of application servers and on the media server, said streaming management software program comprising:

an input module to accept a streaming media data stream as input;

a buffering module to manage buffering levels of the streaming media data stream;

a caching module to determine whether the streaming media data stream should be cached; and

a storage module to store the streaming media data stream on the storage unit of the media server.

11. An internet service system comprising:

a primary server for managing a plurality of application servers;

a network for coupling the plurality of application servers to the primary server;

a server software program running on the primary server for detecting availability and resource usage on the plurality of application servers; and
