On June 28th, Brocade and Viavi announced a joint customer assurance solution that combines the Viavi xSIGHT Targeted Subscriber Search with the Brocade Packet Broker and Brocade Session Director.  The joint solution was built to solve a specific challenge a tier 1 mobile operator was experiencing – reduce the amount of time required to do end-to-end subscriber traces.  These traces are used to help identify the cause of adverse network conditions and provide targeted subscribers with a higher level of service quality.  The Viavi xSIGHT TSS and Brocade joint solution has successfully reduced subscriber trace times from hours to minutes.  This changes the game for network operations as they can now quickly gain access to subscriber traces while the subscriber is on the phone, something not possible with existing solutions.


The existing process to obtain an end-to-end subscriber trace was extremely long and manual.  A subscriber would call into the network operations center with a problem – this could be a specific application they were trying to access or anything service related.  The network operations team did not have the service assurance capabilities to start a end-to-end trace on that subscriber in real-time.  Instead, the tracing request would be sent to another group where a lengthy manual process would occur to try to understanding what is creating the problem for the subscriber.  Eventually, the trace would be complete, but not for hours.  In fact, the average end-to-end subscriber trace takes roughly six hours.  The trace data obtained after 5 hours may or may not be useful since network conditions have likely changed.  This has led to a lot of frustration in network operations since it was difficult to do their job effectively.  They simply didn’t have the data and thus, information to rectify the subscriber problems.  The xSIGHT TSS, powered by Brocade Packet Broker and Brocade Session Director changes this.

The Viavi and Brocade solution enables service providers to capture and analyze subscriber data to quickly resolve quality of experience (QoE) issues on a scale unmatched in the industry. The xSIGHT TSS leverages the Brocade Network Packet Broker and Brocade Session Director to filter and deliver targeted subscriber traffic so only the data required is forwarded to TSS agent. The xSIGHT TSS provides subscriber packet captures to pinpoint the cause of subscriber service degradation.  The solution enables mobile operators to resolve customer experience problems in minutes, providing significant OPEX savings, while opening up opportunities for new services.
