--- title: "Closed Loop Automation (CLA)" date: "2022-04-27T05:52:06+00:00" url: "https://www.allot.com/network-intelligence/technology/closed-loop-automation/" description: "Closed-loop automation is a process of continuously monitoring, measuring, and assessing real-time network operations. It determines network traffic demands and resource availabilities to determine the optimal placement of that traffic for the best Quality of Service (QoE)" --- # Closed Loop Automation (CLA) ## What is Closed Loop Automation (CLA) Closed-loop automation in Communication Service Provider (CSP) networks is a continuous process that monitors, measures, and assesses real-time network traffic and then [automatically acts to optimize end-user Quality of Experience (QoE)](https://www.allot.com/service-providers/network-traffic-management/network-congestion-management/). CLA continuously: - Identifies types of network traffic and collects performance metrics - Calculates bandwidth demands and resource availability - Maps these metrics to user service levels and perceived QoE - Instantly sets [optimal bandwidth allotment](https://www.allot.com/service-providers/network-traffic-management/qos-traffic-shaping/) for each traffic component The result is the best customer QoE and the optimal resource utilization, throughout the network. ## Business Driven Evolution Although these actions happen dynamically, it is important to note that human operators configure the automated actions and can manually modify them at any point within the loop to reflect business priorities. This permits a stepwise, low-risk, and business-driven evolution all the way to full CLA, delivering self-optimization while protecting current investments in personnel and processes. ## CLA Beats Manual Human Analysis Automation has long been prevalent in CSP operations, viewed as a better, more efficient way to solve well-known, well-defined problems. For example, everyone agreed it would be great if OSS Fault Management systems could automatically analyze tens of thousands of alarms to identify the root cause that represented the underlying problem. Clearly, this would be faster than human analysis and mean-time-to-resolution (MTTR) would be greatly reduced. ## CLA in Next Generation Networks As large-scale Software Defined Network/Network Functional Virtualization (SDN/NFV) implementations become prevalent and 5G networks begin to be deployed, it may seem as though sufficient CLA is already baked into the network infrastructure. However, both SDN/NFV and 5G Service Based Networking (SBN) focus on network KPIs and Quality of Service (QoS) to optimize network resources and service delivery. This focus on KPIs and QoS will improve many aspects of network performance but will not necessarily result in optimal end-user QoE. To illustrate the difference between KPIs and KQIs, consider a video streaming service. The end-to-end service KPIs may indicate satisfactory QoS – and the QoE of the end user may be OK on a handheld device. But for a user on a large screen, that same QoS yields insufficient QoE. External CLA solutions should focus on Key Quality Indicators (KQI) and end-user QoE to ensure that customers receive the best services at the highest quality. ## 5G and CLA With [5G’s anticipated IoT explosion](https://www.allot.com/technology/5g-network-security/), external CLA capabilities will also be required to address the ‘unknown unknowns’ presented by the expanded threat landscape. Machine Learning (ML) and Artificial Intelligence (AI) will need to power CLA security solutions that automatically detect new, unknown threats and quickly mitigate them. Independent Software Vendors such as Allot are best positioned to deliver CLA with the ML and AI capabilities that can cost-effectively ensure optimal performance, security, and QoE.

But for CSPs to take full advantage, they require CLA that focuses on end-user QoE, not just network Key Performance Indicators (KPIs). - **Think Growth, Think ISV** – Independent Software Vendors (ISVs) are best positioned to deliver CLA with the ML and AI capabilities that cost-effectively ensure optimal performance, security, and Quality of Experience. - **The CLA Inherent in 5G is Not Enough** – 5G Networks, by design, will feature CLA that handles known problems. But to address and solve unforeseen problems, and to meet QoE expectations, will require additional CLA functionality, powered by AI and ML. ![Telco Smart Trends Report](https://www.allot.com/resources/Datasheets-_2.jpg) Telco Smart Trends Report Closed Loop Automation: What CSPs Need to Know Now and for the Future [Read More](https://info.allot.com/TelcoSecurityTrendsReportQ12019_TelcoTrendsreportLP.html?utm_source=5g_page&utm_medium=website) ![Webinar](https://www.allot.com/resources/solution_paper.jpg) Webinar How to Gain Maximum Value from Closed Loop Automation (CLA) [Learn more](https://info.allot.com/01WBN_13.2.19_How_to_Gain_Maximum_Value_from_Closed_Loop_Automation_03OnDemand-RegistrationLP.html?utm_source=website&utm_medium=website_webinarsod_page) ![Congestion Management](https://www.allot.com/resources/header_subscriber_security_service_6-2.jpg) Congestion Management QoE Assurance through Automated QoS & DDoS Mitigation [Read More](https://www.allot.com/resources/SOL_CONGESTION_MANAGEMENT-1.pdf) [![Allot See Control Secure](https://www.allot.com/assets/img/footer/allot-logo.png)](/) Company - [About Allot](/corporate/about/) - [Blog](https://www.allot.com/blog/) - [Careers](/careers/) - [Contact Us](/contact-us/) - [CyberHub](https://cyberhub.allot.com/) Terms of Use - [Privacy Policy](/privacy-policy/) - [Accessibility Statement](https://www.allot.com/accessibility-statement/) - [Get support](https://customers.allot.com/) - [Terms of Use](/terms-of-use/) - [ ](https://www.linkedin.com/company/allot-communications/) - [ ](https://www.youtube.com/c/Allotltd) - [ ](https://x.com/allot_ltd) - [ ](https://www.instagram.com/allot_ltd/) Copyright 2026 Allot.
