Abstract

A system and method are presented that improve work cooperation among computers. Communication between programs is combined with restart data to travel via a manager on a third computer. Work is represented by a hierarchical set of client to server session pairs that contain restart and message data. Reliability, security, scalability, and aggregate performance are improved with minimal impact on latency of a single piece of work.

Claims

1. A computerized method for sharing work between a client session and a server session comprising:

a) on a client computer operating the client session;

i) generating a request message requesting work to be done,

ii) identifying client restart data necessary to restart the client session,

iii) communicating the request message and the client restart data to a manager computer;

b) on the manager computer;

i) storing the client restart data and the request message in association with a client-server session maintained by the manager computer,

ii) identifying the server session associated with the client-server session,

iii) transmitting the request message to the server session,

c) on a server computer operating the server session,

i) receiving the request message,

ii) performing the work and generating a response message identifying the results of the work,

iii) identifying server restart data necessary to restart the server session, iv) communicating the response message and the server restart data to the manager computer;

d) on the manager computer;

i) storing the server restart data and the response message in association with the client-server session,

ii) transmitting the response message to the client session,

wherein the manager computer periodically backs up all data stored in association with the client-server session to a backup manager computer;

e) on the backup manager computer;

i) identifying an interruption to the manager computer,

ii) establishing communications with the client computer and causing the client session to restart on the client computer,

iii) providing the client session with client restart data, the request queue, and the response queue to facilitate restarting of the client session,

iv) establishing communications with the server computer and causing the server session to restart on the server computer, and

v) providing the server session with server restart data, the request queue, and the response queue to facilitate restarting of the server session;

wherein the request message is stored in a request queue of messages comprising a plurality of request messages, and further wherein the request queue of messages is transmitted from the client session to the manager computer, stored on the manager computer, and transmitted from the manager computer to the server session, and

wherein the response message is stored in a response queue of messages comprising a plurality of response messages, and further wherein the response queue of messages is transmitted from the server session to the manager computer, stored on the manager computer, and transmitted from the manager computer to the client session.

2. The computerized method of claim 1, wherein the request message contains a request identifier to identify the request message in the request queue of messages.

3. The computerized method of claim 2, wherein the response message contains the same request identifier.

4. The computerized method of claim 2, wherein the client restart data includes a new request identifier.

5. The computerized method of claim 1, wherein the request message and the response message both contain a session identifier so as to identify the client-server session to the manager computer.

6. The computerized method of claim 5, wherein the client restart data and the server restart data both include the session identifier.

7. The computerized method of claim 1, further comprising:

f) on the manager computer;

i) identifying an interruption to the server session;

ii) identifying a replacement server session to replace the interrupted server session;

iii) transmitting the server restart data, the request message, and the response message to the replacement server session;

iv) replacing the interrupted server session with the replacement server session in the client-server session;

v) communicating new request messages from the client session to the replacement server session.

8. The computerized method of claim 1, wherein data stored by the management computer in association with the client-server session are maintained in RAM throughout the duration of the client-server session.

9. The computerized method of claim 1, wherein the client computer, the manager computer, and the server computer are physically separate computing devices.

10. The computerized method of claim 1, wherein the client session and the server session operate on the same physical computing device.
