Telecom Operator Network Design Training

I missed writing , missed writing a post lot on the website specifically !. Because I know you are reading right now and wonder where I have been.


I just checked and seen that my last post was on October 26. More than 2 months , I didn’t share anything on the website. I wanted to come here and share something , technical or social , but believe me guys November and December 2017 was so busy from my side.



One of the activity which took my time during this period was Telecom Operator design training which I did in Kenya/Nairobi on November. Safaricom Kenya – Incumbent Telecom Operator/Internet Service Provider. Read more

February 2017 CCDE Training is over ! Waiting the attendees success now !

My February 2017 CCDE class is now over. The duration of the course was for 11 days and as usual it started with lots of advanced technology lessons. All the critical CCDE exam topics (IGP, BGP , MPLS and the other technologies) were covered in detail from the design point of view.

A minimum of 4 hours was spent each day. We had 50+ hours training this time; which helped and engaged the participants during the training. For example, many existing CCDE network engineers shared the CCDE Practical scenarios, CCDE exam tips and tricks and their strategies with the students.


Since I adjust and expand my course outline continuously; each time, students learn more about network design. There were many CCDE Practical Scenarios at the February class and those scenarios definitely will help the attendees in the CCDE Practical exam.


By the way, the next CCDE Practical exam is on 22 February 2017, in 2 days’ time!

I wish all the attendees including my students ‘good luck’ in the upcoming CCDE practical exam. Looking forward to share their feedbacks and the success stories in the future posts.
