Method and apparatus for adaptive network heartbeat message for TCP channel
A method and apparatus for a client to continue to receive updates from a server when a channel has been disconnected before the expiration of a heartbeat timer is disclosed. The method includes sending a heartbeat message from the client to the server wherein the heartbeat message is sent at the expiration of a timer having a first time interval that is less than the first timeout duration period of the server. The method includes detecting that the channel is disconnected before the expiration of the first time interval and then determining a second timeout duration period from detecting the channel is disconnected. After determining the second time out duration, the method includes resetting the first time interval to a second time interval for the sending of the heartbeat message wherein the second time interval being less than the second timeout duration period.
1. An apparatus comprising:
a transceiver for sending messages from a client to a server over a channel and for receiving messages from the server over the channel;
a memory for storing a heartbeat timer value wherein the heartbeat timer value is less than a time out duration and wherein after the expiration of the time out duration the channel between the client and the server is disconnected; and
a processor coupled between the transceiver and the memory wherein the processor detects that the channel is disconnected and, in response to detecting that the channel is disconnected, determines a second time out interval which is less than the first time out interval and resets the heartbeat timer value to a second interval which is less than the determined second time out duration,
wherein the processor further creates a message to be sent by the transceiver to a central data base wherein the message contains the second interval to be used by other clients connected to the server.
