Yogesh, you need to use some form of credit based flow control.

Re: [zeromq-dev] XPUB/XSUB subscriptions and protocol differences between 3.0 and 3.1
Your implementation can decide what versions of ZMTP it wants to detect and support. Different versions use different formats. E.g. if you want to support 3.0 and 3.1 then you'd allow both subscribe commands, depending on the client's version. Note that version negotiation is one-way: client states what version it implements, server accepts/rejects.
