I attended sessions on both TCP Router (Cloud Foundry and IOT protocol support by Atul Kshirsagar) and NoRouter (Norouter: Running Cloud Foundry without the Gorouter by Mike Heath).
I just wanted to start a discussion on the pros and cons of each approach.
As personal opinion I think NoRouter is a simpler approach and can definitely be made to support IOT protocols. The main drawback I see with the NoRouter is the danger of the LTM becoming a Monolith.
