Abstract

An efficient technique for recovering multiple connections detects a connection failure affecting multiple clients, selects one of the number of affected clients, repeatedly attempts to reestablish the failed connection between the selected client and the server until the connection is successfully re-established, and then re-establishes the connections for the remaining clients.

Claims

1. A method for recovering multiple connections in a communication network, the method comprising the steps of:

detecting a failure affecting a plurality of connections;

selecting one of said plurality of connections;

performing a connection establishment procedure to re-establish the selected connection; and

upon successfully re-establishing the selected connection, performing the connection establishment procedure for the remainder of the plurality of connections.

2. An apparatus comprising a computer readable medium having embodied therein computer readable program code means for recovering multiple connections in a communication network, the computer readable program code means comprising:

computer readable program code means for detecting a failure affecting a plurality of connections;

computer readable program code means for selecting one of said plurality of connections;

computer readable program code means for performing a connection establishment procedure to re-establish the selected connection; and

computer readable program code means for performing, upon successfully re-establishing the selected connection, the connection establishment procedure for the remainder of the plurality of connections.

3. A translating apparatus comprising:

logic for detecting a failure affecting a plurality of connections;

logic for selecting one of said plurality of connections;

logic for performing a connection establishment procedure to re-establish the selected connection; and

logic for performing, upon successfully re-establishing the selected connection, the connection establishment procedure for the remainder of the plurality of connections.

4. A system comprising a plurality of clients in communication with a server through a translating apparatus, wherein the translating device comprises:

logic for detecting a failure affecting a plurality of connections;

logic for selecting one of said plurality of connections;

logic for performing a connection establishment procedure to re-establish the selected connection; and

logic for performing, upon successfully re-establishing the selected connection, the connection establishment procedure for the remainder of the plurality of connections.
