Abstract

A connection management system can achieve scalability for domain computing among a plurality of domains. Each of the plurality of domains comprises a collection of machines and resources that are administrated as a unit. A connection concentrator can connect, and support communication between, a plurality of processes in a first domain and a plurality of processes in a second domain. The connection concentrator uses one connection to communicate with any one of the plurality of processes in the first domain, and can communicate with each one of the plurality of processes in the second domain.

Claims

1. A system of connection management to achieve scalability for domain computing, comprise:

a plurality of processes in a first domain, wherein the first domain is one of a plurality of domains, wherein each of the plurality of domains comprises a collection of machines and resources that are administrated as a unit;

a plurality of processes in a second domain, wherein the second domain is also one of the plurality of domains, wherein the plurality of processes in the second domain connect to a connection concentrator to communicate with the plurality of processes in the first domain; and

wherein the connection concentrator communicates with each one of the plurality of processes in the second domain and uses one connection to communicate with any one of the plurality of processes in the first domain.

2. The system of claim 1, wherein:

the plurality of processes in the first domain connect to another connection concentrator to communicate with the plurality of processes in the second domain, wherein the another connection concentrator communicates with each one of the plurality of processes in the first domain and uses one connection to communicate with any one of the plurality of processes in the second domain.

3. The system of claim 1, wherein:

the connection concentrator uses a plurality of handlers to handle communication between the plurality of processes in the second domain and one of the process in the first domain.

4. The system of claim 3, wherein:

the connection concentrator is also associated with a listener, wherein the listener determines which particular handler handles the communication between one of the plurality of processes in the second domain with a particular process in the first domain.

5. The system of claim 1, wherein:

a connection between one of the plurality of processes in the first domain and the plurality of processes in the second domain through the connection concentrator is initiated from within the first domain.

6. The system of claim 1, wherein:

a connection between one of the plurality of processes in the first domain and the plurality of processes in the second domain through the connection concentrator is initiated from within the second domain.

7. The system of claim 1, wherein:

a connection between one of the plurality of processes in the first domain and the plurality of processes in the second domain through the connection concentrator is asymmetric.

8. The system of claim 1, wherein:

a connection between one of the plurality of processes in the first domain and the plurality of processes in the second domain through the connection concentrator is symmetric.

9. The system of claim 1, wherein:

the connection concentrator uses a TCP/IP connection to communicate with any one of the plurality of processes in the second domain.

16. The system of claim 1, wherein:

a connection between one of the plurality of processes in the first domain and the plurality of processes in the second domain through the connection concentrator is asymmetric.

17. The system of claim 1, wherein:

a connection between one of the plurality of processes in the first domain and the plurality of processes in the second domain through the connection concentrator is symmetric.

18. The system of claim 1, wherein:

the connection concentrator uses a TCP/IP connection to communicate with any one of the plurality of processes in the second domain.

10. A method of connection management to achieve scalability for domain computing, comprise:

providing a plurality of processes in a first domain, wherein the first domain is one of a plurality of domains, wherein each of the plurality of domains comprises a collection of machines and resources that are administrated as a unit;

providing a plurality of processes in a second domain, wherein the second domain is also one of the plurality of domains;

connecting the plurality of processes in the second domain to a connection concentrator to communicate with the plurality of processes in the first domain, wherein the connection concentrator uses one connection to communicate with any one of the plurality of processes in the first domain.

11. The method of claim 10, further comprising:

connecting the plurality of processes in the first domain to another connection concentrator to communicate with the plurality of processes in the second domain, wherein the another connection concentrator communicates with each one of the plurality of processes in the first domain and uses one connection to communicate with any one of the plurality of processes in the second domain.

12. The method of claim 10, wherein:

the connection concentrator uses a plurality of handlers to handle communication between the plurality of processes in the second domain and one of the process in the first domain.

13. The method of claim 12, wherein:

the connection concentrator is also associated with a listener, wherein the listener determines which particular handler handles the communication between one of the plurality of processes in the second domain with a particular process in the first domain.

14. The method of claim 10, further comprising:

initiating a connection between one of the plurality of processes in the first domain and the plurality of processes in the second domain through the connection concentrator from within the first domain.

15. The method of claim 10, further comprising:

initiating a connection between one of the plurality of processes in the first domain and the plurality of processes in the second domain through the connection concentrator from within the second domain.

19. A machine readable storage medium having instructions stored thereon that when executed by one or more processors cause a system to:

provide a plurality of processes in a first domain, wherein the first domain is one of a plurality of domains, wherein each of the plurality of domains comprises a collection of machines and resources that are administrated as a unit;

provide a plurality of processes in a second domain, wherein the second domain is also one of the plurality of domains;

connect the plurality of processes in the second domain to a connection concentrator to communicate with the plurality of processes in the first domain, wherein the connection concentrator uses one connection to communicate with any one of the plurality of processes in the first domain.
