TRAFFIC MANAGEMENT COMPLEX

To resolve the set objective, a DPI system (Deep Packet Inspection) by Procera Networks was integrated into the operator's network infrastructure (PCRF). The interfaces for interaction between the two complexes are provided by Jet Infosystems’ JSM software. Jet Subscriber Management is designed specifically for telecom operators’ implementation of dynamic traffic management scenarios in DPI devices.

The pilot launch took place in St. Petersburg, and the implementation of the entire project took 8 months. The project team developed and configured a universal network management model, consisting of more than a thousand rules with the following key principle: in case of traffic fluctuations, interactive services gain the advantage in terms of speed, without affecting the operational stability of other applications.

Finally, the team implemented traffic control for base stations in congested conditions. The IT system analyzes data streams in real time and adjusts flexibly to changing external conditions (increases in the number of subscribers, signal deterioration during bad weather, noise and interference from neighboring stations or buildings, etc.). If necessary, the PCRF gives a command to the DPI system to redistribute the traffic, and users enjoy better service.

Since the ratio between different content types may vary by region, prioritization rules were adjusted pointwise in each city, based on the statistics and the service consumption model at that location.
