For small ISPs, the yardstick against which adding an IX to the mix is usually measured against is the marginal cost of IP transit. Given that the cost of transport is fixed, is it more economical to buy more IP transit or to join an IX?<br><br> Transit being so cheap means that joining an IX isn't always so enticing from a financial perspective, although there are other non-monetary benefits.<br><br> I certainly subscribe to the notion that transport + transit is usually less expensive than DIA, but this does depend on the market and location.<br><br>Jared<br></div><br></div></div></body></html>
