The VAS Experts DPI — Network Traffic Control And Analysis System

The VAS Experts DPI is the deep packet inspection platform designed to inspect and classify packets along with its subsequent processing according the challenges facing the company.

This is a software solution that doesn’t depend on a particular server hardware supplier and can be flexibly adapted to business requirements. The VAS Experts DPI provides high performance at an attractive price.

  • Determining over 6000 protocols.
  • Support for the following operation modes : «machine-in-the-middle» mode, mode using routing asymmetry in outgoing traffic and traffic mirroring mode.
  • Subscriber management with dynamic IP-addressing, with multiple IP-addresses.
  • It is possible to scale the solution to provide traffic handling up to 3.84 Tbit/s.

Features

Independent software platform Independent software platform

Standard hardware powered by Intel Xeon is used as a hardware platform to install the VAS Experts DPI. It makes possible to be independent of a particular equipment supplier, to reduce the value of capital costs and to be able to flexibly scale the solution power depending on the business requirements.

Broad scope of application Broad scope of application

The DPI platform can be used by telecom operators, Internet service providers, marketing agencies, user behavior study centers, search engines and contextual advertising services.

Large set of features Large set of features

In addition to traffic inspection and classification, the DPI platform allows to implement additional functions:

  • Real time analytics.
  • Сhannel allocation between subscribers and the total bandwidth management (QoS).
  • Informing subscribers, advertising.
  • Bonus Program.
  • Caching video and audio content, software updates, etc.
  • Protection against DOS and DDOS attacks.

Advanced technology of traffic analysis and filtration Advanced technology of traffic analysis and filtration

DPI platform parses all the packets passing through it up to the 7th level of the OSI model, instead of just using information about standard port numbers.

When DPI platform performs behavioral (heuristic) traffic analysis, it identifies applications not using well-known headers and data structures for data exchange.

As an example the p2p (Bittorrent) protocol can be considered: a packet sequence analysis based on their similarities as well as a set of signatures matching to similar applications are used to identify traffic.
