Release Notes for Routed Optical Networking Solution, Release 2.0

The release notes provide an overview of the Routed Optical Networking solution and its features. It also lists the caveats.

Routed Optical Networking Overview

Routed Optical Networking simplifies complex multilayer networks by collapsing network layers and minimizing the functional overlap. Routed Optical Networking also improves the overall network efficiency by optimizing each layer of the network. The architecture also integrates open data models and standard APIs, enriching powerful automation making Routed Optical Networking easier to operate than legacy networks.

Routed Optical Networking is able to provide improvements and simplification because it:

  • Leverages state of the art optical and routing technologies to converge services over an IP infrastructure connected by a simplified DWDM layer

  • Merges IP and private line services onto a single unified IP layer

  • Simplifies end-to-end network architecture

  • Utilizes a modern software stack that spans across network management and control planes

  • Improves the capacity and cost efficiency of networks

  • Has a smaller carbon footprint

  • Offers unified capacity planning, unified EMS, unified path optimization, orchestration, and assurance

  • Provides an automation ecosystem with open, programmable, and modular components

  • Total Cost of Ownership savings across CapEx and OpEx

Routed Optical Networking utilizes high-density routers, high-capacity ZR or ZR+ pluggable digital coherent optics, simplified DWDM line systems, and end-to-end multi-layer automation to create next generation networks.

 Description
Simple Optical Line Systems

IOS-XR: 7.7.1

NCS 1010 OLS platform is an integral component of Routed Optical Networking solution. It provides point-to-point connectivity between routers with ZR/ZR+ optics and multiplexes signals from multiple routers over a single fiber. The OLS platform supports ROADM nodes of up to eight degrees.

The NCS 1010 OLS platform provides:

  • Versatility by supporting multiple coherent sources

  • Simplicity by using integrated Optical line cards that minimize fiber patching and cabling errors in the field.

  • Automation through IOS XR operating system that provides a rich suite of automation features including Zero Touch Provisioning (ZTP), open config YANG model support with NETCONF, and streaming telemetry.

  • Network Monitoring through a combination of probes based on OTDR, OSC, OCM, and telemetry data.
OpenConfig support for ZR/ZR+

IOS-XR: 7.7.1

You can manage the pluggable digital coherent optics using open models from the OpenConfig consortium.
Private Line Emulation

IOS-XR: 7.7.1

Private line emulation (PLE) enables service providers to carry SONET/SDH, OTN, Ethernet, and Fiber Channel over a circuit-style segment routed packet network while maintaining existing service SLAs.

Private Line Emulation (PLE) utilizes Circuit Emulation (CEM) to transparently transfer PLE client frames over MPLS or Segment Routing networks without changing the characteristics of the original signal.

The following table contains open caveats on the Crosswork Hierarchical Controller:

Open Caveats Workaround

[NMC Crosslinks] links are removed when line card is reloaded or interfaces disappear (HW OIR)

The application adds the cross layer links (OCH → OLS) directly to the database without state. In case an interface disappears for any period (such as during a line card reload), the link disappears and does not return when the interface returns.

None

After changing the credential profile where the CNC adapter was not using the updated password in the adapter Devices under the CNC adapter continued to show as "OK".

The failed auth message from CNC does not get relayed in the logs under response during provisioning. Instead, it shows an internal HCO error: '<=' not supported between instances of 'int' and 'AssertionError'.

[CNC adapter] when changing credentials, the adapter does not pick the new credentials.

Restart the CNC Adapter in HCO
