1. A method of disconnecting a first computer from a second computer, the first computer and the second computer being connected to a broadcast channel, said broadcast channel forming an m-regular graph where m is at least 3, the method comprising:
- when the first computer decides to disconnect from the second computer, the first computer sends a disconnect message to the second computer, said disconnect message including a list of neighbors of the first computer; and
when the second computer receives the disconnect message from the first computer, the second computer broadcasts a connection port search message on the broadcast channel to find a third computer to which it can connect in order to maintain an m-regular graph, said third computer being one of the neighbors on said list of neighbors.

Abstract
A method for leaving a multicast computer network is disclosed. The method allows for the disconnection of a first computer from a second computer. When the first computer decides to disconnect from the second computer, the first computer sends a disconnect message to the second computer. Then, when the second computer receives the disconnect message from the first computer, the second computer broadcasts a connection port search message to find a third computer to which it can connect.

6. A method for healing a disconnection of a first computer from a second computer, the computers being connected to a broadcast channel, said broadcast channel being an m-regular graph where m is at least 3, the method comprising:
-
attempting to send a message from the first computer to the second computer; and
when the attempt to send the message is unsuccessful, broadcasting from the first computer a connection port search message indicating that the first computer needs a connection; and
having a third computer not already connected to said first computer respond to said connection port search message in a manner as to maintain an m-regular graph. - View Dependent Claims (7, 8, 9, 10)
when a third computer receives the connection port search message and the third computer also needs a connection, sending a message from the third computer to the first computer proposing that the first computer and third computer connect.

8. The method of claim 7 including:
when the first computer receives the message proposing that the first computer and third computer connect, sending from the first computer to the third computer a message indicating that the first computer accepts the proposal to connect the first computer to the third computer.
-
9. The method of claim 6 wherein each computer connected to the broadcast channel is connected to at least three other computers.
-
10. The method of claim 6 wherein the broadcasting includes sending the message to each computer to which the first computer is connected.
-
11. A computer-readable medium containing instructions for controlling disconnecting of a computer from another computer, the computer and the other computer being connected to a broadcast channel, said broadcast channel being an m-regular graph where m is at least 3, comprising:
-
a component that, when the computer decides to disconnect from the other computer, the computer sends a disconnect message to the other computer, said disconnect message including a list of neighbors of the computer; and
a component that, when the computer receives a disconnect message from another computer, the computer broadcasts a connection port search message on the broadcast channel to find a computer to which it can connect in order to maintain an m-regular graph, said computer to which it can connect being one of the neighbors on said list of neighbors. - View Dependent Claims (12, 13, 14, 15, 16)
a component that, when the computer receives a connection port search message and the computer needs to connect to another computer, sends to the computer that sent the connection port search message a port connection message indicating that the computer is proposing that the computer that sent the connection port search message connect to the computer.

13. The computer-readable medium of claim 12 including:
a component that, when the computer receives a port connection message, connecting to the computer that sent the port connection message.
-
14. The computer-readable medium of claim 11 wherein the computers are connected via a TCP/IP connection.
-
15. The computer-readable medium of claim 11 wherein the computers that are connected to the broadcast channel are peers.
-
16. The computer-readable medium of claim 11 wherein the broadcast channel is implemented using the Internet.
