Re: TCP Router VS NoRouter

Owais Mohamed

Apologize for restarting this thread after a few weeks.

That's right Mike. Once the LTM opens up to the developers they might start putting in too much functionality into the Load Balancer like filters, interceptors. By using NoRouter the LTM will have to be opened up to the developer team.

I know that there has to be discipline and access control. But was just putting it out as con in the NoRouter Section.

Hoping that Chip does not have concerns with discussing NoRouter here. Let me know and I can take this discussion offline.

Hi Owais,

What are you referring to when you say you're concerned about the LTM becoming a Monolith? Too much functionality in one component? Too much of the system depending on one component?


Hopefully it's ok to discuss NoRouter here even though it isn't an official CF project. Let us know if it is not.

The "norouter", while interesting, isn't the official CF project approach to HTTP traffic routing. The TCP router is being built to support TCP routing as a general solution, with the goal of it becoming an official part of the CF release when ready.

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.

Any suggestions\ideas?
