Who would notice if the brand of modem OS changed?How much are the modem designs built with VxWorks in mind? Is WIND simply a preferred supplier de jour or do they actually have some lock on this business? Without the lock, you have no gorilla. You're asking the right questions. I wish I kneW the answers. As to complexity, I would say an optical switch is probably as complex as a PC. As to the lock, I think it has a lot to do with market share and dedicated resources. Imagine that you are a modem manufacturer (actually, I think this is probably not a great example, since we are assuming a company making a single product, but it will work). Lets say you have 10 engineers on your staff developing modems (note: I know nothing about whether this company should have one engineer or 100. 10 is just for this example). You have purchased a Tornado development seat for each of them, at a total cost of hundreds of thousands of dollars. They know this system, because they have worked with it to develop the last two years worth of products your company has put out. You want to use Conexant's new chip for your next modem, so you order a sample that arrives with VxWorks already burned in for testing. Your engineers play around with it, and you decide to go with it, but you need to get it to market right away, because if your competition beats you to market, you will lose market share, and those stock options you got two years ago that can be exercised in three months may not be worth much, even though you already know what you will spend the proceeds on. ARE YOU GOING TO CHANGE THE DEVELOPMENT ENVIRONMENT?
