Abstract:
1. A communication connection controller comprising: a function determination module configured to determine whether a control failure recovery function comprising one or more of a resynchronization function and a control information retrieval function is to be enabled for a segment of a data communication connection that is to be established between a source communication device and a destination communication device, the segment being established between a local communication device comprising the controller and a remote communication device comprising a remote controller by communicating control information between the controller and the remote controller, the data communication connection comprising a plurality of segments including the segment; and a control failure recovery module, operatively coupled to the function determination module, configured to include in the control information communicated with the remote controller to establish the data communication connection an indication that the control failure recovery function is supported at the controller, the function determination module being configured to determine whether the control failure recovery function is to be enabled by determining whether one or more of: a request to enable the control failure recovery function for the data communication connection, an indication that the remote controller supports the control failure recovery function, and an indication that a further remote controller of a further remote communication device supports the control failure recovery function for a further data communication connection segment between the local communication device and the further remote communication device, is received at the local communication device, the control failure recovery module being configured to include the indication in the control information where the control failure recovery function is to be enabled.
