Imagine a day in the life of a network operator working at a large Tier 1 service provider. You start your day as you would any other, but as you go to take that first sip of morning coffee you observe that some issue has occurred in the network. Not long after, you find yourself inundated with alarms from multiple systems. The race against the clock has begun, and you must quickly correlate, isolate, and resolve these faults before their impact spread throughout the network and adversely impacts quality of service for your customers.

What could be the root cause issue? Where to start looking? What impact is it having on customers? These are the pertinent questions that need to be addressed.

In the case of traditional fault systems, Network Operations Center (NOC) personnel face significant hurdles when attempting to identify, diagnose, and resolve network issues as a result of the disparate, legacy operations systems that have evolved over time. Network operations must undergo the tedious process of manually correlating alarms from several systems in order to pinpoint the root cause. Compounded by the fact that service providers must also deal with impacted customer quality of experience (QoE) as triage time increases, this process quickly becomes costly in more ways than one.

What’s more, the rise of the Internet of Things (IoT), Software Defined Networking (SDN), and Network Functions Virtualization (NFV) have resulted in added operational complexities forcing service provides to reassess their approach to service assurance.

Typically, traditional fault management systems provide a device-centric, rather than a user-centric, view of the network, hindering the ability to monitor and visualize important fault information. In order to understand how a single resource fault may be impacting several logical services utilizing that resource, and the customers who rely on those services, an operator must swivel-chair between systems.

Furthermore, traditional fault management systems are not able to support SDN controllers, NFV infrastructure elements, or virtual network functions, such as virtual firewalls or virtual loadbalancers. The gaps in these fault systems also force operators to swivel-chair between systems in order to understand and act on key trends regarding historical fault activity, network key performance indicators (KPIs), network inventory, and service topology.

As next-gen services and infrastructure become integrated into the network, service providers require a service assurance solution that extends the value of their existing fault systems and bridges the gap between physical and virtual infrastructure.

CENX has delivered a solution that revolutionizes network analytics and troubleshooting to help mitigate widespread network issues, assure customer QoE, and enable network operators to do their jobs most effectively.

Exanova Service Intelligence’s software enables network operators to quickly isolate faults by leveraging network analytics through its unique ability to correlate the overwhelming amount of data across multiple technologies and network functions into a single monitoring dashboard. By continuously ingesting and contextualizing fault data with information from network services, customers, topology, and service quality KPIs from other IT systems, service providers can reduce their triage time by as much as 90%. In addition to historical reporting and analytics, Exanova also provides proactive capabilities by enriching fault data and holding it in temporal data stores, providing the basis for predictive, automated service assurance.

Furthermore, Exanova provides an at-a-glance view of all physical and virtual segments of the network in a single pane of glass with real-time inventory and performance dashboards. As a result, NOC personnel can accelerate break/fix troubleshooting more rapidly than can be done with traditional fault management systems. Network faults can now be quickly located and triaged down to a fine granularity of individual objects in the service path, such as ports, nodes, segments, and services thanks to Exanova’s real-time circuit path topology visualization and fault isolation.

CENX’s orchestrated service assurance solution allows service providers to reduce their triage time from days to minutes, isolate faults right down to the circuit path segments, and reduce operational costs. At the end of the day, this provides customers with unparalleled service quality and allows network operators to enjoy their morning coffee for a little longer.
