Hi,
we have two years of experience in using the IPv6-flowlabel to transmit
timecritical data (for example vocoded voice) and conventional data at the same
time over heterogenouse networks including those of low bandwhith ( in the
moment ISDN, GSM, HF, seriel modem, gateway to usual phone etc..).
We use the flowlabel to transmit flow_id and QoS-parameters for channel resorce
management in any packet. In the moment we have implementationes on Linux
Solaris and BSD and start inernational tests.
We are interesting in any work around the flowlabel. With RFC 2553 we are
unlucky, because it is said that the system sets the (random) value of
flowlabel. For us it is important that the aplication can set and read this
value. I think a good solution for the flowlabel should include this
possibility.
We are interesting in any colaboration and discussion to write a draft.
Best Regards
Peter
