Med, > > I would like to make two comments: > * The implementers I have in mind are CPE vendors and Carrier-Grade platform manufacturers. > * Implementation does not come for free. > Independently of the topic of this email, I'd like to point out that in the MPTCP working group most of the important decisions have been validated by early prototypes that have been evaluated and discussed in the working group. I think that this has served as an important "reality check" in the working group and has probably contributed to the good results that we have achieved with the various deployments that have been documented. With the open-source implementation of Multipath TCP in the Linux kernel, the cost of developing a prototype is not as high as developing a hardware implementation in some working groups. Coming back to the proxy topic, TCP/MPTCP proxies have already been demonstrated, e.g. in http://inl.info.ucl.ac.be/publications/multipath-middlebox and extensions of this idea are deployed in the field. I'm not aware of similar work showing that UDP can be safely encapsulated inside MPTCP for reactive applications. Best regards, Olivier
