Automate 5G Core Network Design with AMCOP and ABot: A Joint offering Aarna Networks and Rebaca
April 26, 2021
Sriram Rupanagunta is a co-founder & SVP Engineering at Aarna Networks, Inc, and heads their engineering team. Prior to Aarna, Sriram was the Head of India Engineering at Data Center Business of Western Digital Corp. Prior to Western Digital, Sriram was with the SSD based startup Virident Systems (which was acquired by Western Digital). Earlier to that, Sriram was also the co-founder of start up Aarohi Communications which was acquired by Emulex Corporation, and was the Vice President, Technology at Emulex. He lives in Bangalore, India with his wife and a daughter.
With 5G, the entire environment becomes cloud/edge and software-driven, unlike 4G. This makes network service management which includes orchestration, lifecycle management (configuration and security settings), and service assurance complex and not viable via existing mechanisms. Given the flexibility with software, the permutations of configuration and security settings for 5G result in a very large number, and choosing the right settings becomes very challenging. So, having to sort through these different configurations and combinations makes the eventual network service deployment a big challenge.
Redundant or missing test vectors in a test suite identification
Root Cause Analysis and Event Suppression thus facilitating in debugging
Completely cloud-native and seamless integration with any Orchestrator and CI/CD pipeline
Distributed deployment across Operator’s Network, Cloud Provider’s Data Centre and Edge Network
Network functions simulated by ABot can be deployed as Kubernetes pod on any hypervisor
Can be managed by any Network Orchestrator like AMCOP, OSM, Juju, Cloudify, etc.
Key Features of AMCOP:
Kubernetes cluster registration
Cloud-Native Network Function (CNF) and Cloud-Native Application (CNA) onboarding
Network Service (with CNFs) or Composite Application (with CNAs) design
Intent-Based Orchestration of network service or composite application
Ongoing lifecycle management and day 1, 2 configuration of network service or composite application
Monitoring of CNFs or CNAs resulting in real-time policy-driven closed-loop automation
A high-level block diagram of AMCOP is shown below:
A joint solution with AMCOP and ABot results in seamless design of a 5G core as follows:
AMCOP is used to configure and provision any 4G and 5G Network Function with both SUT and ABot emulated nodes
AMCOP then invokes ABot end-to-end test scenarios to exercise different use cases
ABot Analytics captures different Mobility KPIs, Infra KPIs, and other test statistics
ABot Analytics can provide relevant analytics insights to AMCOP (as events)
AMCOP’s Analytics Program (AAP) drives orchestration and configuration changes, and if needed, reruns the tests to make sure the new configuration is what we desired.
With AMCOP and ABot working together, one can automate the entire process by going through this closed-loop repeatedly and arrive at an ideal environment/configuration. It will also help the user understand how the network would work under different configurations. In this manner when the 5G Core is put into production, the user is assured that it will work optimally to meet their specific requirements.
