Abstract

A method of establishing a logical association between connections. A datum is generated at a first node in response to a request from a second node. The datum is sent to the second node via a first connection. An application program is also sent to the second node. The application program is for the second node to interface with the first node to establish the second connection and to assist in associating the first connection with the second connection. A command is received by the first node from the second node via a second connection. The command includes the datum. A logical association is then established between the first connection and the second connection in response to receiving the command.

Claims

1. A method of establishing a logical association between connections, said method comprising:

a) generating a datum at a first node in response to a request from a second node;

b) sending said datum to said second node via a first connection;

c) sending an application program to said second node, said application program for said second node to interface with said first node to establish a second connection and to assist in associating said first connection with said second connection;

d) receiving a command at said first node from said second node via a second connection, said command including said datum; and

e) establishing a logical association between said first connection and said second connection in response to receiving said command.

2. The method of claim 1, wherein said first connection is a connectionless connection and said second connection is a connection oriented connection.

3. The method of claim 2, wherein said command is a Telnet command.

4. The method of claim 3, further comprising sending a second Telnet command to said second node requesting said second node to send said datum back to logically associate said first connection with said second connection.

5. The method of claim 4, wherein said Telnet commands are Telnet suboption commands, wherein said first node and said second node engage in a Telnet suboption negotiation.

6. The method of claim 4, further comprising:

f) sending a third Telnet command to said second node via a third connection, said third Telnet command requesting said second node to send said datum back to associate said first connection with said third connection; and

g) establishing said logical association to further include said third connection in response to receiving a fourth Telnet command that includes said datum, said fourth Telnet command being received from said second node.

7. The method of claim 4, further comprising:

f) sending a third Telnet command to said second node via a third connection, said third Telnet command requesting said second node to send said datum back to associate said first connection with said third connection; and

g) establishing a second logical association, said second logical association being between said first connection and said third connection, said establishment in response to receiving a fourth Telnet command that includes said datum, said fourth Telnet command being received from said second node.

8. The method of claim 1, wherein:

a) comprises generating a plurality of datums at said first node in response to requests from a plurality of nodes;

b) comprises sending said plurality of datums to said plurality of nodes via a plurality of first connections;

c) comprises sending a plurality of application programs to said plurality of nodes;

d) comprises receiving a plurality of commands at said first node from said plurality of nodes via a plurality of second connections, said commands including said plurality of datums; and

e) establishing said logical association between said plurality of first connections and said plurality of second connections in response to receiving said plurality of commands.

9. The method of claim 1, wherein:

a) further comprises storing said datum and connection specific items for said first connection and associating said datum with said items; and

d) further comprises associating said items with said second connection.

10. A computer readable medium having stored thereon instructions, which when run on a processor execute a method of establishing a logical association between connections, said method comprising:

a) generating and storing a connection identifier at a first node in response to a request received via a first connection from a second node;

b) sending said connection identifier over said first connection to said second node;

c) sending an application program to said second node, said application program for performing a negotiation to associate said first connection with a second connection; and

d) establishing a logical association between said first connection and a second connection in response to receiving a Telnet command at said first node, said received Telnet command including said connection identifier.

11. The computer readable medium of claim 10, wherein said method further comprises sending a Telnet command via said second connection to said second node, said sent Telnet command requesting said second node to send said connection identifier in said received Telnet command.

12. The computer readable medium of claim 10, wherein said sent and received Telnet commands are Telnet suboption commands.

13. The computer readable medium of claim 10, wherein:

a) of said method further comprises storing said connection identifier and connection specific items for said first connection in a table and linking said items with said connection identifier; and

d) of said method further comprises associating with said second connection said items in said table that are linked with said connection identifier.

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

e) sending a third Telnet command via a third connection to said second node, said third Telnet command requesting said second node to send said connection identifier back to associate said first connection with said third connection; and

f) establishing said logical association to further include said third connection in response to receiving a fourth Telnet command that includes said connection identifier.

15. The computer readable medium of claim 10, wherein said method further comprises:

e) sending a third Telnet command to said second node via a third connection, said third Telnet command requesting said second node to send said connection identifier back to associate said first connection with said third connection; and

f) establishing a second logical association, said second logical association linking said first connection with said third connection, said establishment in response to receiving a fourth Telnet command that includes said connection identifier.

16. The computer readable medium of claim 10, wherein:

a) of said method comprises generating and storing a plurality of connection identifiers at said first node in response to requests from a plurality of nodes;

b) of said method comprises sending said plurality of connection identifiers to said plurality of nodes via a plurality of first connections;

c) of said method comprises sending a plurality application programs to said plurality of nodes; and

d) of said method comprises establishing said logical association between said plurality of first connections and said plurality of second connections in response to receiving a plurality of second Telnet commands that include said plurality of connection identifiers.

17. A method of establishing a logical association between connections, said method comprising:

a) establishing a first connection between a first node and a second node;

b) said second node generating and storing an identifier at said first node;

c) said second node sending said identifier to said first node;

d) said first node and said second node performing a Telnet suboption negotiation to establish said logical association between said first connection and a second connection, said suboption negotiation taking place via said second connection, said suboption negotiation comprising;

d1) said second node sending a Telnet suboption command to said first node indicating said first node should return said identifier to associate said first connection with said second connection;

d2) said first node sending said identifier to said second node in a Telnet suboption command; and

e) said second node associating said first connection with said second connection.

18. The method of claim 17 wherein e) comprises said second node verifying that said identifier is a stored identifier.

19. The method of claim 17, wherein c) further comprises:

sending an application program to said first node, said application program for said first node to interface with said second node to establish said second connection.
