SDH/SONET

I just finished "Cisco Self-Study: Building Cisco Metro Optical Networks (METRO)" as a part of my preparation for written exam.

What can I say about this book - less than 1/5 of the whole book is about SONET/SDH/DWDM, the other part is more like marketing material with screenshots of management system, etc.

I am comfortable on this topic, hence can go to next one.

Looking forward to read more about IPoDWDM:


1.2.1. Optical channel payload unit (OPU)
1.2.2. Optical channel data unit (ODU)
1.2.3. Optical channel transport unit (OTU)
1.2.4. Optical channel (OCh)
1.2.5. Shared Risk Link Group (SRLG)
1.2.6. Virtual Transponder (VTXP)
1.2.7. FEC-FRR Triggering
1.2.8. Optical Parameters- Rx-los-threshold, Wavelength and Transmit-power
1.2.9. G.709 Parameters 

Actually, don't see here any IP (except as a payload) :))

Here you can find some Cisco IPoDWDM propaganda (slides).

UPD: Looks like this is updated version of the METRO book: Building Multiservice Transport Networks

Beginning of the Journey

One more CCIE blog... WHY?


There is a plenty of CCIE-related blogs, but I decided to start my very own for personal reasons. I really hope, that:

  • blogging will help me to more deeply understand the topics of the exam (and remember them)
  • it will be useful for other CCIE candidates
  • practice in written English (English is not my mother-tongue) 
  • fun
Which track I want to pass?

I want to pass CCIE Service Provider track. The reason is simple - I like the topics of the exam and I'm working in the service provider market.

What is my plan?

My plan is to prepare for the CCIE SP Written Exam (350-029), after - take a lab exam in 6 months.

Why I want to pass this exam?

I don't work for Cisco or any Cisco partner, it's not a part of my IPM (individual performance management for this year), I already have a great job in the networking field - why I should do that? It's simple - I want to prove my knowledge and experience in neutral way, i.e. pass mostly respected IP technology exam (yes, I know about JNCIE).

Do I have other certifications in IP field?

Yes, I have. Maybe 5 or 6 years ago I have passed the CCNA/CCDA exams (was easy, actually). After that, I passed couple of other non-Cisco exams in IP field.

Do I have a family?

Yes, I have a family and my wife promised me full support. 

Let's start the journey!
