Feature Description


Note


This feature is Network Services Orchestrator (NSO) integrated.

The Cisco Common Data Layer (CDL) is a high-performance next generation Key-value (KV) data store layer for all the Cloud Native applications. These applications use the CDL as a state management with High Availability (HA) and Geo HA functions. The CDL provides:

  • Different Network Functions (NFs) - such as AMF, cnBNG Control Plane, SMF, and PCF - microservices.

  • Multi-master support to achieve low latency read and write.

  • Pure in-memory storage.

  • Session related timers to notify NF on timer expiry.

Deploying CDL provides the following benefits:

  • Service-Based Architecture (SBA) with auto discovery and global accessibility.

  • High performance, in-memory caching and in-memory data store.

  • Container-based solution from the ground up.

  • CDL can deploy and scale with simple API calls.

  • Geo Redundant Replication among multiple cnBNG clusters.

For detailed information about CDL, refer to the UCC SMI Common Data Layer Configuration and Administration Guide at https://www.cisco.com/c/en/us/support/wireless/ultra-cloud-core-subscriber-microservices-infrastructure/products-installation-and-configuration-guides-list.html.
