OTN – Lesson 12 – APS Features within Atomic Functions – Part 1

This blog post presents a video that discusses the APS features within some of the Atomic Functions that we discussed in Lessons 9 and 10.

Lesson 12 – Video 12 – Detailed Implementation of APS within the Atomic Functions – Video 1

This blog post starts our discussion of the APS Features within various Atomic Functions. In this case, we will present how to implement Automatic Protection Switching in great detail. In particular, we will describe the following:

  • APS Features within the OTUk/ODUk_A_So and OTUk/ODUk_A_Sk functions (OTU-Layer/SNC/I Monitoring)
    • How do we implement the APS features within these Atomic Functions to support OTU-Layered SNC/I Monitoring and Protection-Switching?
    • How do we implement a complete System-Level design (using these atomic functions along with the OTUk_TT_So and OTUk_TT_Sk Atomic Functions)?
      • NOTE: We discussed these atomic functions in Lesson 9. However, we did not discuss the APS features (within those functions) then.
  • APS Features within the ODUkP/ODUj-21_A_So and ODUkP/ODUj-21_A_Sk functions (ODU-Layer/SNC/I Monitoring)
    • How do we implement the APS features within these Atomic Functions to support ODU-Layered SNC/I Monitoring and Protection-Switching?
    • How do we implement a complete System-Level design (using these atomic functions along with the ODUk_TT_So and ODUk_TT_Sk Atomic Functions)?
      • NOTE: We discussed these atomic functions in Lesson 10. However, we did not discuss the APS features (within those functions) then.
  • APS Features of the ODUkP/ODUj-21_A_So and ODUkP/ODUj-21_A_Sk functions (CL-SNCG/I Monitoring)
  • How do we implement the APS features within these Atomic Functions to support CL-SNCG/I Monitoring and Protection-Switching?
  • How do we implement a complete System-Level design (using these atomic functions along with the ODUk_TT_So and ODUk_TT_Sk Atomic Functions)?
    • NOTE: We discussed these atomic functions in Lesson 10. However, we did not discuss the APS features (within those functions) then.

OTN – Lesson 12 – Introduction to SNCP (Subnetwork Circuit Protection)

This blog post introduces the concept of SNCP (Subnetwork Circuit Protection) Switching. This post also briefling introduction SNCP Monitoring schemes such as SNC/I, CL-SNCG/I, SNC/Ne, SNC/Ns and SNC/S.

Lesson 12 – Video 3 – Introduction to SNCP (Subnetwork Circuit Protection) Switching

This blog post contains a video that covers the introductory part of Subnetwork Circuit Protection switching.

In particular, this video will discuss the following topics:

  • Introduction to the concept of Subnetwork Circuit Protection (SNCP)-Switching
    • How is SNCP different from Trail Protection Switching
    • Why does the Industry prefer SNCP Monitoring/Switching instead of Trail Protection Monitoring/Switching?
  • Introduction to the following forms of SNCP Monitoring:
    • SNC/I – Subnetwork Circuit/Inherent Monitoring
    • CL-SNCG/I – Compound Link – Subnetwork Circuit Group/Inherent Monitoring
    • SNC/N – Subnetwork Circuit/Non-Intrusive Monitoring
      • SNC/Ne – Subnetwork Circuit/Non-Intrusive (End-to-End) Monitoring
      • SNC/Ns – Subnetwork Circuit/Non-Intrusive (Sublayer) Monitoring
    • SNC/S – Subnetwork Circuit/Sublayer Monitoring

We will cover each of these monitoring forms (for Protection-Switching purposes), in much greater detail, throughout the remaining videos in Lesson 12.

In particular, we will cover these forms of SNCP Monitoring (in detail) in the following videos.

This particular video provides a broad overview of each of these forms of monitoring.
