Abstract

A system and method of streaming data in real time and, more particularly, a system and method of real time streaming of data over a grid network or other distributed infrastructure. The method and system includes updating a content directory of a root server with end resource information. The method and system further includes processing the end resource information to determine connection locations for streaming data to at least one requesting end resource in a network.

Claims

1. A system comprising:

a CPU, a computer readable memory and a computer readable storage medium;

program instructions to update a content directory of a root server with end resource information of a plurality of end resources receiving a stream of data in a network, the end resource information associating each of the plurality of end resources with a location in the network and one or more applications that are accessing the streaming data;

program instructions to process the end resource information by a first end resource included in the plurality of end resources to determine connection locations for accessing the stream of data;

program instructions to stream the stream of data by the first end resource from one or more of the connection locations based on one or more types of the applications accessing the stream of data at the first end resource; and

program instructions to tag the plurality of end resources with hierarchy level designations indicating a quality of the stream of data available from each of the plurality of end resources,

wherein the program instructions are stored on the computer readable storage medium for execution by the CPU via the computer readable memory.

2. The system of claim 1, further comprising program instructions to update the content directory each time a new connection is made to the root server or a triggering event occurs.

3. The system of claim 1, wherein:

one of the plurality of end resources is a streaming server, responsive to a request by another of the plurality of end resources; and

the streaming server streams the streaming data to the another of the plurality of end resources over the network.

4. The system of claim 3, wherein:

the streaming server is tagged with a first tag associated with a first tier streaming resource;

the another of the requesting end resources is tagged with a second tag associated with a second tier streaming resource; and

the first tag indicates higher quality data than the second tag.

5. The system of claim 3, further comprising program instructions to update the content directory with new information concerning the streaming server including at least one of a tag type and a type of data which is streaming to the another of the requesting end resources.

6. The system of claim 1, wherein:

each of the plurality of end resources is configured to act independently of one another; and

the root server is designated as a master stream server for broadcasting the stream of data in real-time to the first end resource.

7. The system of claim 1, wherein the content directory is dynamically built, in real-time, as the first end resource connects to the root server.

8. The system of claim 1, wherein the end resource information includes information and/or characteristics of and associated with the first end resource.

9. The system of claim 8, wherein the end resource information includes:

listings of locations of the plurality of end resources;

data requested from the first end resource;

bandwidth requests and/or bandwidth capabilities of the first end resource;

quality of data which is requested to be received from the root server;

delays of the streaming data that the plurality of end resources are receiving; and

listings of pieces of the streaming data that the plurality of end resources are receiving from which of the plurality of end resources.

10. The system of claim 9, wherein resource connection information is used by the first end resource to make a connection determination to the root server and/or another end resource.

11. The system of claim 1, wherein the first end resource is at least one of:

data storage resources on a grid infrastructure, multiple end user machines running over the network, a server, in a client server relationship, a user workstation and a personal computer.
