Protecting Revenues: Slashing SLA Breaches by 60% with Proactive Network Remediation

TL;DR

• The Challenge: High risks of core network SLA breaches, slow detection-to-action times measured in hours, and imminent threat of expensive compliance penalty costs.

• The Solution: Implemented continuous monitoring of core network KPIs coupled with automated, rule-based thresholds that trigger instant traffic rerouting and resource reallocation.

• The Result: Dropped SLA breaches by 60%, transformed detection-to-action times from hours to minutes, and lowered penalty risk costs by 25%.

The Situation

In core telecom service delivery, meeting stringent Service Level Agreements (SLAs) is critical. The operator faced a high risk of breaches due to manual tracking of Packet Core and Circuit Core (PS/CS) network performance. When network metrics degraded, identifying the issue and taking action took hours, resulting in financial penalty exposure and low customer satisfaction.

The Spark

We shifted the operational model from reactive firefighting to proactive prevention. By continuously analyzing health scores and automating corrective actions right as metrics approach breach limits, the network can heal itself before customers or SLAs are ever impacted.

The Solution

We deployed a rule-based threshold and remediation framework to guarantee continuous SLA compliance:

• KPI Data Lake: Utilized Splunk Core as an on-premise event lake to aggregate and monitor key core network metrics.

• Health Scoring: Leveraged Splunk ITSI to define service models, assign real-time health scores, track episodes, and map SLA performance.

• Policy Trigger Bus: Deployed Kafka to serve as the high-speed policy trigger bus for immediate rule evaluation.

• Diagnostics & Self-Healing: Integrated Splunk SOAR + Ansible AWX to run pre/post-check diagnostic bundles and execute automated fixes (e.g., traffic rerouting, resource reallocation, or service restarts).

• Compliance Tracking: Connected BMC Helix ITSM for automated ticket updates and evidence tracking, supported by dashboarding and weekly compliance reporting packs.
