Abstract

A private network is built by first allowing a pre-determined number of client systems to connect directly to a server system. After this occurs, additional client systems requesting connection are furnished with the addresses of client systems already connected within the private network. Each of the additional client systems then makes connections with a multiple number of client systems to receive information from the server system. Each of these client systems subsequently accepts connections from up to a second pre-determined number of client systems to which it transmits information received from the server system.

Claims

1. A process for connecting client systems within a private network, wherein said process comprises the steps of:

(a) connecting client systems, up to a first pre-determined maximum number thereof, directly to a server system through a public network;

(b) connecting additional client systems within a plurality thereof, beyond said first pre-determined maximum number thereof, to other client systems to form said private network extending through connections within said public network to said server system;

wherein each client system within said plurality thereof is connected to a second pre-determined number of client systems within said plurality thereof through said public network for receiving information from said server system;

wherein each said client system is connectable to up to a pre-determined number of client systems for transmitting information through said public network from said server system;

Wherein said step (b) includes the steps of;

(d) transmitting a request for connection from an additional client system within said plurality thereof to said server systems;

(e) transmitting addresses, of said second pre-determined number of available client systems connected within said private network, to said additional client system from said server system; and

(f) establishing connections between said additional client system and said second pre-determined number of available client systems connected within said private network.

2. The process of claim 1, additionally comprising a step (c) of maintaining said second pre-determined number of connections between each client system within said plurality thereof and other client systems within said plurality thereof, for receiving information from said server system by establishing new connections among said client systems when a disconnection occurs.

3. The process of claim 1, wherein each available client system within said second pre-determined number thereof has connected thereto for receiving information therefrom fewer than a third pre-determined number of client systems within said plurality thereof.

4. The process of claim 2, wherein said step (c) includes the steps of:

(g) transmitting a disconnection notification to said server system from a partly disconnected client system within said plurality thereof, wherein said partly disconnected client system has been connected for receiving information from said server system to a client system disconnecting from said private network;

(h) transmitting, from said server system to said partly disconnected client system, an address of an available client system within said plurality thereof connected within said private network; and

(i) establishing a connection between said available client system and said partly disconnected client system.

5. The process of claim 4, wherein said available client system has connected thereto for receiving information therefrom fewer than a third pre-determined number of client systems within said plurality thereof.

6. A process executing within a server system for establishing a private network of client systems within a plurality thereof to receive information from said server system, wherein said process comprises the steps of:

(a) receiving a request for connection from a client system issuing said request;

(b) determining if a port of said server system is available for connection with said private network;

(c) if a port of said server system is available for connection within said private network, as determined in step (b), connecting said client system issuing said request to said port;

(d) if a port of said server system is not available for connection within said private network, as determined in step (b), sending to said client system issuing said request a first pre-determined number of addresses of available client systems within said plurality thereof connected within said private network; and

(e) adding an address of said client system issuing said request to a list of addresses within a database residing in said server system.

7. The process of claim 6, comprising in addition the steps of:

(f) receiving a disconnection notification from a partly disconnected system within said private network, wherein said partly disconnected client system has been connected for receiving information from said server system to a client system disconnecting from said private network;

(g) sending to said client system issuing said disconnection notification an address of a client system within said plurality thereof connected within said private network; and

(h) removing an address of said client system disconnecting from said private network from a database including addresses of client systems connected within said private network.

8. The process of claim 7, wherein, within said steps (d) and (g) said available client systems have fewer than a second predetermined number of client systems attached thereto for transmitting information received from said server system.

9. A process executing within a particular client system for establishing a private network of client systems within a plurality thereof to receive information from a server system, wherein said process comprises the steps of:

(a) transmitting a connection request to said server system;

(b) receiving addresses of available client systems within said private network from said server system;

(c) connecting to said available client system for receiving information from said server system;

(d) receiving a connection request from an additional client system within said plurality thereof; and

(e) establishing a connection with said additional client system to transmit information received from said server system.

10. The process of claim 9, additionally comprising the steps of:

(f) being disconnected from a first client system connected within said private network between said particular client system and said server system;

(g) transmitting a notice of disconnection to said server system;

(h) receiving an address of an available client system connected within said private network from said server system; and

(i) establishing a connection with said available client system identified by said address received in step (h).

11. A computer readable medium upon which coded steps are written for a process executing within a server system for establishing a private network of client systems within a plurality thereof to receive information from said server system, wherein said process comprises the steps of:

(a) receiving a request for connection from a client system issuing said request;

(b) determining if a port of said server system is available for connection with said private network;

(c) if a port of said server system is available for connection within said private network, as determined in step (b), connecting said client system issuing said request to said port;

(d) if a port of said server system is not available for connection within said private network, as determined in step (b), sending to said client system issuing said request a first pre-determined number of addresses of available client systems within said plurality thereof connected within said private network; and

(e) adding an address of said client system issuing said request to a list of addresses within a database residing in said server system.

12. The medium of claim 11, wherein said process comprises in addition the steps of:

(f) receiving a disconnection notification from a partly disconnected system within said private network, wherein said partly disconnected client system has been connected for receiving information from said server system to a client system disconnecting from said private network;

(g) sending to said client system issuing said disconnection notification an address of a client system within said plurality thereof connected within said private network; and

(h) removing an address of said client system disconnecting from said private network from a database including addresses of client systems connected within said private network.

13. The medium of claim 12, wherein, within said steps (d) and (g) said available client systems have fewer than a second predetermined number of client systems attached thereto for transmitting information received from said server system.

14. A computer readable medium upon which coded steps are written for a process executing within a particular client system for establishing a private network of client systems within a plurality thereof to receive information from a server system, wherein said process comprises the steps of:

(a) transmitting a connection request to said server system;

(b) receiving addresses of available client systems within said private network from said server system;

(c) connecting to said available client system for receiving information from said server system;

(d) receiving a connection request from an additional client system within said plurality thereof; and

(e) establishing a connection with said additional client system to transmit information received from said server system.

15. The medium of claim 14, wherein said process additionally comprises the steps of:

(f) being disconnected from a first client system connected within said private network between said particular client system and said server system;

(g) transmitting a notice of disconnection to said server system;

(h) receiving an address of an available client system connected within said private network from said server system; and

(i) establishing a connection with said available client system identified by said address received in step (h).
