RES: RES: Software For Telcos

[takashi at cpqd.com.br (Takashi Tome)]

HAHA! Good joke!

That was true some 30 years ago...

Actually, I think the problem is quite different. Big telco's network is a very complex thing - well, you all can say, Internet is too...
But if we see some "similar" business like aircraft-defense and professional video market, we see some similarities: there are a lot of tricks and "non-documented standards" that make those software a kind of mistery for foreigners. Put in other words, software knowledge is not enough, you must have a deep understanding of that business and the history of the system itself...

in my miniscule experience, they have large masses of engineers with unrequited NIH and roll their own as much as possible.  after all, who could make something suitable for their oh so special needs.
