Syntax
Default: bidirectional-optimistic
Returns the command to its default setting.
Returns the command to its default setting.
This mode is similar to the Unidirectional mode, with the exception of a feedback channel used to send error
recovery requests from the decompressor to compressor.
recovery requests from the decompressor to compressor.
Reliable mode makes extensive use of a feedback channel to avoid packet loss from context invalidation. A
secure reference model is used instead of the optimistic approach used in the other modes. With the secure
reference model, the confidence of the compressor depends on acknowledgements from the decompressor for
every context updating packet.
Periodically the compressor sends context updating packets repeatedly until an acknowledgement is received
from the decompressor.

Packets are sent in only one direction, from the compressor to the decompressor.
Usage
Use this command to specify the preferred feedback method to use between the compressor and the
decompressor for the current RoHC profile.
decompressor for the current RoHC profile.
