As legacy networks shift from hardware to software components and begin to integrate virtualized technologies, such as software-defined networking (SDN) and network functions virtualization (NFV), assuring service quality has become a key focus for service providers in order to differentiate themselves from competitors.


A comprehensive service assurance approach that provides detailed network analytics and bridges the operational gaps between physical and virtual infrastructure is paramount to help deliver premium quality of experience (QoE) to customers, and to avoid the increased operational complexities and costs that are associated with the adoption of NFV. Since the NFV market is expected to reach a value of $15.5 billion by 2020, end-to-end orchestrated service assurance provides significant opportunities to service providers attempting to keep pace with the exponential growth rate of data services. 

The value of service assurance comes in its ability to enable service providers to optimize their service operations. Accordingly, this can be done in three ways: network impact analysis, network capacity management, and saving expenditures.

Network Impact Analysis

In today’s competitive market, where customers expect a high level of QoE, service providers must be able to accurately manage and understand the increasing amount of complex network data they encounter daily. A strategic service assurance approach must be implemented in order to accurately monitor network performance and provide operators with the information they need to make informed decisions. Service providers who utilize a service assurance solution, such as CENX’s Exanova Service Intelligence, are able to explore real-time and historical analytics across multiple data sources to enhance fault isolation and performance management. Additionally, this level of network analysis greatly expedites troubleshooting capabilities, helping to mitigate widespread network issues.

Network Capacity Management

Another major value of service assurance is its ability to enable service providers to plan service upgrades efficiently. As many operators are aware, network planning and service provisioning is essential to efficiently deliver services and maximize end-user QoE. Through Exanova Service Intelligence’s detailed analytics processed , service providers are able to correlate utilization and performance data to target capacity upgrades in the areas of the network needing them most. Service providers are also able to meet market demand by accelerating service turn-up times and streamlining workflow processes. Thanks to a strategic service assurance approach, service providers are able to reduce operational costs, and most importantly, maintain customer service-level commitments. 

Saving Expenditures

Attempting to maximize profits amidst the relentless changes in the telecoms industry can be a challenge. However, applying a service assurance approach can aid service providers to reduce opex and capex associated with their network operations. Operators can utilize a strategic approach to limit costly network upgrades when and where increased capacity is needed, thus controlling capex spend. Service providers are able to streamline triage and mean time to repair processes and also avoid manual inventory reconciliation, which decreases opex dramatically and enhances service availability and quality. Lastly, service assurance aids Service Level Agreement (SLA) management, since service providers can maintain accurate reports of how their partner providers are performing, and hold those providers accountable to contracted service levels, thus optimizing their opex spend.

Ultimately, the benefits of service assurance are vast, spanning operations across multiple domains, and essential to all aspects of a service provider’s network. Learn more about how CENX’s Exanova Service Intelligence can help meet all of your service assurance needs.
