Subject: Re: [smartgrid-interest] What's wrong with having devices communicate in their own native languages
Brian, I almost agree with you but I have a question: in your analogy of gateway/routers, where do you see QOS, Firewall, IPSec, SNMP, etc. be implemented at? I am sure you do not mean that all end points will implement QOS, IPSec, etc. and, therefore, at least there are some high level functions that the end points will not understand regardless of their protocol. Does this mean endpoints should not be IP based, no, not at all. It just means that there are system boundaries which have not yet been well defined. As such, to me, talking about the transport protocol now without boundary requirements is tantamount to building a software system based on an operating system (of course, nothing wrong with this but not very scalable).
