Wireshark-dev: [Wireshark-dev] Packet reassembling
HI all.
I know Wireshark can reassemble packets, and I have found several
reassembling strategies, but it seams that none of them is suitable for
me.
In my dissect function I'm receiving a buffer that consist of 32 bytes
- this is one frame. Each byte of this frame is called timeslot, and
enumerated from 0 to 31, e.g timeslot0, timeslot1, ....
Each timeslot can be divided into several sub-channels, for example
bits 0 -1 from timeslot0 will be sub-channel1, bits 2-3 will be
sub-channel2, and so on, it's like applying bit mask on timeslot(0xC
for sub-channel1, 0x30 for sub-channel2, ...).
To collect data of some sub-channel, we must take certain amount of
bits at certain offset from the beginning of the frame, add them to
buffer and continue doing this for each frame we have captured.
Fragment disassembling is not applicable here because concatenation of two frames will not be helpful.
Segment fragmentation is also not applicable because here work must be done with bits.
So can someone make some suggestions how to implement reassembling for this protocol?
Thank you.
