Discovery: architecture #1
Ask the customer to draw his system on the white board. Every customer will say that their system is special, but 99.9% of customers will draw this picture: PC Controller Router Gateway Controller Router Gateway Controller Router Gateway Devices

i.LON Selection Once you know the basic architecture discover….
Does you need a router or gateway? Understand this distinction !!!! Do you need peer-2-peer binds? Does your system have a PC connected? Will that PC be running LNS? Will you be polling or binding? What are your performance requirements? Do you need web access? Do you need SOAP access? Do you need to translate LONWORKS network variables to XML? Do you need to allow simultaneous access to multiple PCs? What is the total size of your network? Which enterprise systems will you connect to? What are your power supply / mounting restrictions? Do you need scheduling, alarming & data logging applications? Do you need pulse inputs or general purpose inputs? Do you need relay outputs? Do you have broadband access? If not, what are the modem characteristics?
