Overview

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:

  • A Common Data Store Layer across different Network Functions (NFs) - such as AMF, SMF and PCF - Microservices.

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

  • Pure in-memory storage.

  • Runs session related timers to notify NF on timer expiry.

  • High Availability and Geo Redundancy with fast failover
