TELCOPERF01-BP03 Deploy the control plane network functions on centralized locations to meet high scalability and agility requirements

Running the control plane nodes in centralized geographical locations is a strategy used to meet the demands for high scalability and mobility. Centralizing the control plane components in strategically placed data centers enables efficient resource management, load balancing, and fault tolerance across the distributed system. This approach allows the system to better handle sudden traffic increases, support many client nodes, and provide reliable failover mechanisms in case of individual node failures.

Desired outcome:

  • Deploy the control plane components of the telco network in centralized, strategically placed data centers.

  • Achieve high scalability and mobility for the control plane to handle sudden increases in traffic and support a large number of client nodes.

  • Provide reliable failover mechanisms and fault tolerance for the control plane functions.

Common anti-patterns:

  • Distributing control plane components across multiple geographic locations without a centralized strategy.

  • Failing to scale control plane resources appropriately to meet demand spikes.

  • Lacking robust failover and redundancy mechanisms for critical control plane functions.

Benefits of establishing this best practice:

  • Improved scalability and agility to handle dynamic traffic patterns and sudden surges in demand.

  • Enhanced fault tolerance and reliability through centralized control plane architecture.

  • Efficient resource management and load balancing across the distributed telco network.

  • Simplified operations and maintenance of the control plane components.

  • Reduced operational costs through optimized resource utilization.

Level of risk exposed if this best practice is not established: High

Implementation guidance

Running the control plane nodes of a telco network in centralized geographical locations is a strategic approach to meet the demands for high scalability and mobility. By consolidating the control plane components in strategically placed data centers, telco operators can achieve efficient resource management, load balancing, and fault tolerance across the distributed system. This centralized control plane architecture allows the network to better handle sudden traffic increases, support many client nodes, and provide reliable failover mechanisms in case of individual node failures.

The control plane components, responsible for functions like authentication, authorization, and mobility management, can be scaled more effectively in a centralized deployment, maintaining that the overall network can adapt to changing demands and maintain consistent service quality. Moreover, the centralized control plane design simplifies operations and maintenance, as the critical functions are managed in a consolidated manner. This approach enables telco operators to leverage advanced monitoring, automation, and orchestration capabilities to optimize the performance and reliability of the control plane.

When implementing this best practice, telco operators should carefully select the geographical locations for the control plane data centers, considering factors such as network latency, data sovereignty, and disaster recovery planning. The control plane components should be deployed with high availability and redundancy mechanisms to verify continuous operation and seamless failover in case of infrastructure failures.

Implementation steps

  • Identify the key control plane components and functions within your telco network architecture.

  • Deploy the control plane components in centralized AWS Regions, using Amazon EC2 instances or Amazon EKS clusters to host the highly available and redundant control plane infrastructure.

  • Configure AWS Route 53 for DNS and service discovery, enabling efficient communication between the control plane and user plane components.

  • Implement Amazon CloudWatch and AWS CloudTrail to monitor the health, performance, and security of the centralized control plane deployment.

  • Set up AWS Lambda functions to automate the scaling, failover, and recovery processes for the control plane components, maintaining efficient resource utilization and rapid response to changes in demand.

  • Regularly test the control plane failover and disaster recovery procedures using AWS services like Amazon EC2 Auto Scaling, AWS CloudFormation, and AWS Backup.
