Re: Transactions and operations



Juergen,

I am proposing that we use a representation that improves
functionality, adds flexibility, improves transaction robustness
(such as the two user race condition I mentioned yesterday),
improves intelligibility, and can also be implemented in a
device with modest resources.

And while it is the case that memory budgets are getting larger,
it is also the case that intelligence is being added to smaller
and smaller devices, too.

I like to challenge this conventional wisdom. Or to say it
differently: I do not need netconf to manage my low cost personal
integrated access point or my personal low cost five port 10/100 Mbit
Ethernet switch. I need netconf for the more critical network
infrastructure where I am actually willing to pay for getting the
ingredients such as proper cross device transaction support which
netconf promises to deliver.

In other words, I think that we need to be careful with just accepting
arguments like "this is too much to expect from a low cost device".
Perhaps the device is designed for a market where the features
hopefully provided by netconf at least initially do not play a big
role and so be it. Once netconf is successful to run backbone boxes
more reliable and at lower costs, I am sure we will see that the costs
for netconf will easily be justified on little devices.

Several years ago, people could not imagine to have TCP in low end
devices. And still some years ago, people did not expect to have
full blown HTTP servers in embedded devices. And in the management
world, people could not imagine that requiring management agents to be
more than dumb peek 'n poke interfaces will ever work. Does this WG
plan to follow this tradition?
