Re: Capacity planning , transit vs last mile
Like. Good question.

Re: [nanog] GoDaddy
Thanks, Eddie. Yes, I also have been experiencing intermittency this week. But yesterday/today things went worse: I simply can not reach neither some sites hosted there, neither GD's admin area. Neither their call centre... :-( Takashi Tome network dummy 2014-05-16 0:00 GMT-03:00 Eddie Aquino : > What issues are you experiencing?

Hi all. Does anyone know whether GoDaddy is alive/down? thanks Takashi
GoDaddy down again?
Hi All, Does anyone knows whether GoDaddy is having problems again? (I'm not able to reach some sites). Thanks Takashi Tome
RES: RES: Software For Telcos
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...

RES: Software For Telcos
Hi Jacob, Generally, top telcos use software made by top telco's software vendors... of course :-) Say in other words, top telco's equipment vendors have their own sw team or third-party suppliers. Equipment vendors are Alcatel, Lucent (ex-AT&T), Ericsson, Nokia, etc. You can see at those companies' web site to check. Which kind of software: - system and service management; - CRM; - switching, IMS, etc; - billing; and so on. Hope it works.

The tracking of Customer circuits to ensure that from marketing,sales,accounts and technical department everything to do with the circuits has to be tracked. Anyone with any help in regards to top software that can be used to run such a telco to ensure that world class service is obtained will be crucial. Regards, Jacob
