other advantages of the cerent 454 included: smaller form factor, higher port density, greater chip integration, and lower power consumption than competitors at the time. the unit also was the one of the first network element to utilize tcp/ip and a web server on its management interface (the first tcp/ip management network was ditech communications in its dwdm system, marketed in 1996) meaning it could be managed over a standard tcp/ip network as opposed to a more restrictive osi network interface which was the standard in telecom networks at the time. this decision, while initially controversial, was promoted by chip roberson, for two pragmatic reasons: first, a tcp/ip stack came packaged with the embedded operating system from wind river systems and, second, the cost to acquire, test and support an osi stack and associated network was comparatively cost-prohibitive for a young startup.
