# TELCOREL02-BP04 Introduce an SCTP load balancer designed for control-plane network functions, carrier-grade performance, and high availability
<a name="telcorel02-bp04"></a>

 The major public cloud services providers lack native support for load balancing of the Telecom services that rely on control-plane signaling protocols like SCTP (Stream Control Transmission Protocol). It is recommended to introduce a cloud-based SCTP Load Balancer for control plane network functions, designed specifically for telco workloads in the public cloud. Such a solution will provide SCTP protocol awareness, including support for multi-homing and association management, along with carrier-grade performance. The load balancer should also deliver high availability through failover and health checks, maintaining reliable and scalable operation of critical telecommunications components deployed in the public cloud. 

 **Desired outcome:** 
+  Provide a cloud-based SCTP load balancing solution specifically designed for telco control plane workloads. 
+  Offer built-in support for the SCTP protocol in the network functions, including features like multi-homing, stream multiplexing, and association management. 
+  Verify high availability through redundancy, failover capabilities, and health monitoring. 

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

## Implementation guidance
<a name="implementation-guidance-26"></a>

 To enhance the reliability of telecom networks, an SCTP load balancing solution should be onboarded and deployed. This load balancer should incorporate SCTP-specific features, verify high throughput and low latency, and be implemented with high availability and fault tolerance through redundant deployments and automated failover. Integrate the load balancer with Kubernetes-based network functions, optimize for carrier-grade performance, and implement comprehensive monitoring and automation practices to deliver a reliable and responsive telecom infrastructure. 

### Implementation steps
<a name="implementation-steps-24"></a>
+  Select an SCTP load balancer: 
  +  Research and evaluate available SCTP load balancer solutions that offer the required features, such as multi-homing, stream management, and association tracking. Verify the selected product can scale to handle the throughput and latency requirements of telco control plane workloads. 
+  Implement high availability and fault tolerance: 
  +  Deploy the SCTP load balancer across multiple AWS Availability Zones for redundancy. 
  +  Configure health checks and automated failover mechanisms to verify continuous service availability. 
  +  Use AWS Auto Scaling to dynamically scale the load balancer instances based on traffic patterns. 
+  Optimize for carrier-grade performance: 
  +  Configure the SCTP load balancer to optimize for the specific requirements of telco control plane workloads. 
+  Implement comprehensive monitoring and observability: 
  +  Use Amazon CloudWatch to monitor the SCTP load balancer's performance, availability, and error metrics. 
  +  Configure Amazon CloudWatch alarms and Amazon SNS notifications for proactive alerting and incident management.
