Communication connection control systems and methods are disclosed. If a
control failure recovery function is to be enabled for a data
communication connection established by a communication connection
controller by communicating control information with a remote controller,
an indication that the control failure recovery function is supported at
the controller is included in the control information communicated with
the remote controller. Each of the controller and the remote controller
may support, for example, either or both of a local control information
recovery function or a resynchronization function to reduce the amount of
time that the data connection is interrupted during a temporary failure
of one of the controllers.
