Abstract

Methods and apparatus, including computer program products, for measurement in data forwarding storage. A method includes, in a network of interconnected computer system nodes, receiving a request from a source system to store data, directing the data to a computer memory, storing information about the data in a store associated with a central server, and continuously forwarding the data and the store from one computer memory to another computer memory in the network of interconnected computer system nodes without storing on any physical storage device in the network.

Claims

1. A method comprising:

in a network of interconnected computer system nodes, receiving a request from a source system to store at least one data item;

directing the at least one data item to a node;

storing information about the at least one data item in a store associated with a central server;

in response to the request from the source system, continuously forwarding the at least one data item and the store among the nodes in the network of interconnected computer system nodes without storing the forwarded at least one data item on any fixed storage medium in the network, the forwarded at least one data item being constantly routed within the network from node to node, and each of the forwarded at least one data item being available for retrieval if a request to retrieve the data is received, the continuously forwarding comprising;

determining an address of a node available to receive the at least one data item and the store based on one or more factors;

sending a message to the source system with the address of a specific node for the source system to forward the at least one data item or the store;

detecting a presence of the at least one data item or the store at the specific node; and

forwarding the at least one data item or the store to another node in the network of interconnected computer system nodes without storing the forwarded at least one data item on any fixed storage medium.

2. The method of claim 1 wherein continuously forwarding further comprises applying a time stamp to the at least one data item at the specific node.

3. The method of claim 2 wherein the one or more factors comprise network traffic analysis and available memory.

4. The method of claim 1 wherein the information about the at least one data item includes a type, size and ownership.

5. The method of claim 1 further comprising:

receiving a request from the source system to retrieve the at least one data item being continuously forwarded in the network of interconnected computer system nodes;

retrieving the at least one data item from a node in response to the request to retrieve the at least one data item; and

deleting information about the retrieved at least one data item in the store associated with the central server.

6. The method of claim 5 wherein retrieving comprises:

matching the data request at a central server using a hash mark representing the at least one data item entering a node;

sending a message to a node that is predicted to have the at least one data item, the message instructing the node to forward the at least one data item to the source system; and

sending a confirmation message to the central server that the at least one data item has been forwarded to the source system.

7. The method of claim 6 further comprising receiving an acknowledgment from the source system that the requested at least one data item has been received.

8. The method of claim 1 further comprising:

receiving a request for data information in the store;

parsing the request to determine what is being requested;

retrieving the store from a node in response to the request;

generating a report from information in the store matching the parsed request; and

forwarding the report to the source system.

9. The method of claim 8 wherein the report comprises a number of files being forwarded, a number of file types being forwarded, a number representing a physical size of data being forwarded, user-specific information or group-specific information.

10. A tangible computer readable medium embodying instructions for causing a data processing apparatus to perform a method for storing data in a network of interconnected computer system nodes, the method comprising:

receiving a request from a source system to store at least one data item;

directing the at least one data item to a node;

storing information about the at least one data item in a store associated with a central server;

in response to the request from the source system, continuously forwarding the at least one data item and the store among the nodes in the network of interconnected computer system nodes without storing the forwarded at least one data item on any

fixed storage medium in the network, the forwarded at least one data item being constantly routed within the network from node to node, and each of the forwarded at least one data item being available for retrieval if a request to retrieve the data is received, the continuously forwarding comprising;

determining an address of a node available to receive the at least one data item and the store based on one or more factors;

sending a message to the source system with the address of a specific node for the source system to forward the at least one data item or the store;

detecting a presence of the at least one data item or the store at the specific node; and

forwarding the at least one data item or the store to another node in the network of interconnected computer system nodes without storing the forwarded at least one data item on any fixed storage medium.

11. The computer readable medium of claim 10 wherein the continuously forwarding further comprises applying a time stamp to the at least one data item at the specific node.

12. The computer readable medium of claim 11 wherein the one or more factors comprise network traffic analysis and available memory.

13. The computer readable medium of claim 10 wherein the information about the at least one data item includes a type, size and ownership.

14. The computer readable medium of claim 10 wherein the method further comprises:

receiving a request from the source system to retrieve the at least one data item being continuously forwarded in the network of interconnected computer system nodes;

retrieving the at least one data item from a node in response to the request to retrieve the at least one data item; and

deleting information about the retrieved at least one data item in the store associated with the central server.

15. The computer readable medium of claim 14 wherein the retrieving comprises:

matching the data request at a central server using a hash mark representing the at least one data item entering a node;

sending a message to a node that is predicted to have the at least one data item, the message instructing the node to forward the at least one data item to the source system; and

sending a confirmation message to the central server that the at least one data item has been forwarded to the source system.

16. The computer readable medium of claim 15 wherein the method further comprises receiving an acknowledgment from the source system that the requested at least one data item has been received.

17. The computer readable medium of claim 10 wherein the method further comprises:

receiving a request for data information in the store;

parsing the request to determine what is being requested;

retrieving the store from a node in response to the request;

generating a report from information in the store matching the parsed request; and

forwarding the report to the source system.

18. The computer readable medium of claim 17 wherein the report comprises a number of files being forwarded, a number of file types being forwarded, a number representing a physical size of data being forwarded, user-specific information or group-specific information.
