OTN – Lesson 12 – Detailed Discussion of SNC/S Monitoring (Protection Switching)

This blog post presents a video that describes (in detail) SNC/S (Subnetwork Circuit Protection – Sublayer) Monitoring for Protection Switching.

Lesson 12 – Video 7 – Detailed Discussion of SNC/S (Subnetwork Circuit – Sublayer) Monitoring for Protection Switching

This blog post contains a video that presents a detailed discussion of SNC/S (Subnetwork Circuit – Sublayer) Monitoring for Protection Switching purposes, at the ODU Layer.

In particular, this video will discuss the following topics:

  • A Detailed Review of SNC/S (Subnetwork Circuit Protection/Sublayer) Monitoring.
  • This video shows example locations/conditions of where we would use SNC/S Monitoring and why we would use this form of monitoring.
  • This video also highlights similarities of SNC/S with SNC/I Monitoring.
  • It also shows the distinct differences between SNC/S and SNC/Ne or SNC/Ns monitoring.
  • Finally, this video reviews a Multi-Administrative Domain Network (and
    Tandem Connection Monitoring) and describes how SNC/S works within a given “Protect Domain”.

OTN – Lesson 11 – Tandem Connection Monitoring Multi-Administrative Domain Defect Analysis – Part ONE

This blog post contains the first of two videos that analyzes how the Multi-Administrative Domain uses Tandem Connection Monitoring to respond to service-affecting defects within the ODU signal passing through it.

Lesson 11 – Video 10 – TCM Multi-Administrative Domain Defect Analysis – Part ONE

This blog post contains a video covering the first part of the Multi-Administrative Domain Walk-Through when defects are occurring.

In particular, this video discusses how the Multi-Administrative Domain will respond to the presence of defects.

During this video, we are assuming that we are experiencing a service-affecting defect within the ODU signal (that passes through the Multi-Administrative Domain). However, in this case, we are assuming that the defect occurs outside of any of the administrative regions. As we analyze the Multi-Administrative Domain’s response to this defect, we will cover the following topics:

  • What exactly occurs within an ODU signal that experiences a service-affecting defect.
  • How do ODU-layer, ODUT-layer, and OTU-layer circuitry respond to such defects?
  • How does each Administrative Domain respond to the presence of a service-affect defect outside of the Service-Requesting (or any other Domain), using Tandem Connection Monitoring?
  • What does the Path Terminating Equipment (at the remote-terminal) do in response to this service-affecting defect?

I hope that the student will better understand Tandem Connection Monitoring as we go through this and the next video.

OTN – Lesson 11 – Tandem Connection Monitoring Multi-Administration Domain Walk-Thru – Part TWO

This post serves as Part TWO (and the Final Part) for the Multi-Administrative Domain Walk Through and Analysis for our study of Tandem Connection Monitoring.

Lesson 11 – Video 9 – TCM Multi-Administration Domain Walk Through – Part TWO

This blog post contains a video that covers the second (and final) part of the Multi-Administrative Domain Walk-Through.

In particular, this video covers the following topics:

  • Part TWO of our Multi-Administration Domain Walk-Through (using our knowledge of TCM-related atomic functions to analyze this network).

In particular, this post covers the following parts of the Multi-Administration Domain Walk-Through.

  • Initializing the Serving Operating Domain (Operator B) – TCM Level 3
  • Terminating the Serving Operating Domain (Operator B) – TCM Level 3
  • Initalizing the Serving Operating Domain (Operator C) – TCM Level 3
  • Initializing the Protect Domain – TCM Level 4
  • Terminating the Protect Domain – TCM Level 4
  • Terminating the Serving Operating Domain (Operator C) – TCM Level 3
  • Terminating the Leased Service Serving Operator Domain – TCM Level 2
  • Terminating the Service Requesting Domain – TCM Level 1

This video serves as Part TWO (and the Final Part) of our Multi-Administration Domain Walk-Through and Analysis.

This blog post briefly introduces the Tandem Connection Monitoring Controller Atomic Function. This post also serves as Part ONE for the Multi-Administrative Domain Walk Through and Analysis.

Lesson 11 – Video 8 – TCM Controller and Multi-Administration Domain Walk-Through – Part ONE

This blog post contains a video that covers the first part of the Multi-Administrative Domain Walk-Through.

In particular, this video covers the following topics:

  • An Introduction to the TCM (Tandem Connection Monitoring) Controller Atomic Function

    • Definition/Introduction to the Source Compound Function
    • Definition/Introduction to the Sink Compound Function
  • Part ONE of our Multi-Administration Domain Walk-Through (using our knowledge of TCM-related atomic functions to analyze this network).

In particular, this post covers the following parts of the Multi-Administration Domain Walk-Through.

  • Initializing the Service Requesting Domain – TCM Level 1
  • How We Initialize the Leased Service Serving Operator Domain – TCM Level 2
  • Initializing the Serving Operating Domain (Operator A) – TCM Level 3
  • Terminating the Serving Operating Domain (Operator A) – TCM Level 3

This video serves as Part ONE of our Multi-Administration Domain Walk-Through and Analysis.
