Where is the Network API?

At the recent "Rethinking Communications" conference, several panelists commented about the difficulty of creating anything like an application program interface to "the network." APIs are a common way to hide the details of any application or function from software developers. The idea is to compartmentalize functions enough that a developer doesn't have to know how everything works; only what is necessary to invoke some function or operation, or add some function.

Right now the problem is that the "network" is full of subsystems that aren't actually unified enough to present a single API to any third party developer. IP Multimedia Subsystem will help, and right now Session Initiation Protocol comes as close as anything to being an API, though the analogy is rough.

The other issue: programmers, almost by nature, will stress test the limits of any network demarcation a network wishes to expose. "Give them an inch; they'll take a mile," Trevor Baca, Jaduka VP, says.

That isn't likely to raise comfort levels on the carrier side. But some middle ground has to be reached if carriers are to benefit from skills third party developers can put to work.
