Dear RoHC ers,
I am facing ambiguity regarding handling of Mode Cancellation for IR &
IR-Dyn Packets in Profile -0x0004 (RFC 3843).
RFC 3843 says:
The Mode parameter for the value mode = 0 (packet types UOR-2, IR
and IR-DYN) is redefined
to allow the compressor to decline a mode transition requested by
the decompressor:
Mode: Compression mode. 0 = (C)ancel Mode Transition
Upon receiving the Mode parameter set to '0', the decompressor MUST
stay in its current mode of operation and
SHOULD refrain from sending further mode transition requests for the
declined mode for a certain amount of time.
Q.1) How do we communicate mode parameter (i.e, '0' for Mode cancellation)
to Decompressor for IR & IR-Dyn Packets?
RFC 3095/ 3843 has not defined any field indicating 'Mode' in IR
/IR-Dyn Packet formats for Profile-0x0004.
But UOR-2 Packet can communicate mode value in the form of
Extension-3.
Q.2) Is this interpretation correct?
Can we define a field for mode parameter in Dynamic chain (in IR &
IR-Dyn packets) and communicate the mode value
to De-compressor, by indicating it as '0' for handling of Mode
Cancellation.
Will the above implementation give any impact in Interoperabilty?
Pls share your valuble thoughts regarding the same.
Thanks,
Pradeep.
