I am in process of designing opensips which can handle a million users,
hypothetically 200,000 registrations and 500CPS capacity. I've been reading
a lot and learnt that TCP design is blocking and not suitable for huge
My requirement was to have TLS between endpoints and Opensips and hence
riding over TCP is the only option. I needed some expert suggestions on
what things should be taken care of when planning a large deployment over
I have built similar stuff on UDP and I trust it heavily as it has
performed perfectly as expected. But when it comes to TCP I'm a bit
I've read about lot of global parameters that is now available for
asynchrous tcp operations. Is it really helpful when planning for scalable

Thanks for any suggestions !!
