 Thanks for referring the RFC. I just go through to it, yes, there may be issue of acceptability for OPTION headers.

However, OPTION headers provides opportunity to pass some information to the networks. For the proof of concepts, we can do this until to explore a new way :)to survive FlowLable information. 

looking forward for comments.

We have design an algorithm which stores Flowlabel information in IPv4 header.For storage we use the OPTION field of IPv4(24 bit long).Further, each intermediate router (IPv4 only)will extract the Flowlable information and will provide flow base service to a long session of multimedia communication.
