Correlation of Network Traffic and Maintaining Network Visibility

A 1 has a vast network of over 10,000 base stations which carry network traffic. As a service provider, the company is dependent on two major components – the ability to correlate traffic flows on a per-subscriber basis and maintain visibility across all segments of the mobile network. A massive influx of user traffic was overwhelming for the monitoring box placed in one rack. One monitoring box is capable of monitoring a maximum of 60 Gbit traffic. High-speed inline monitoring devices are expensive, and the more features they have the less network traffic they can successfully parse. The scalability of the tools infrastructure cannot match the increases in the volume of information traversing through the mobile service provider network. Furthermore, proliferating tools across the network to monitor millions of subscribers can be very expensive. The company wanted a tool which could aggregate, filter and load balance the network traffic. Besides facing the challenge of dealing with growing network traffic and weak monitoring boxes, the company also wanted a solution which was cost efficient. How do you maximize your investment in a network visibility solution while gaining the most value from the deployed solution?
