General description

Our filtering solution helps the operator to save on development and support of a solution of his own. It has several advantages over a proxy server. Additionally, the operator gets the platform that enables him to save resources and get an income by providing new value added services.

Required components:

Advantages:

1) Easy to use:

  • all rules are applied at one place: on DPI platform;
  • the platform loads and applies rules from lists by itself.

2) Productivity:

  • the list includes up to 4 billion URL records. Its representation in memory is compressed;
  • up to 65000 web-lists;
  • traffic capacity up to 400 Gbpds per one CPU;
  • unlimited scaling by simple installation of additional servers;
  • propagation delay is less than 30 μs.

3) Functionality:

  • HTTP/HTTPS/QUIC protocols are supported for web filtering;
  • URL for HTTP, SNI/CN for HTTPS/QUIC protocols;
  • HTTP and HTTPS/QUIC traffic regardless of the service port being used;
  • filtering for HTTP proxy is supported (including Opera Turbo/Mini);
  • the software can consider or ignore the port number (i.e. block http://www.example.com and http://www.example.com:8080 together or separately);
  • does not depend on IP address changes;
  • redirection instead of blocking is supported for HTTP;
  • incapsulation of VLAN, QinQ, MPLS is supported;
  • support of asymmetric traffic routes, including processing of outbound traffic only;
  • support of mirrored traffic;
  • provides many other useful capabilities, unlike dedicated filtering solutions.

4) "Four nine's" reliability:

  • works 24×7 with no breaks and service delays;
  • uptime of the systems already installed is many months;
  • the Bypass mode is supported to calm the operator.

5) Cost saving:

  • DPI runs on a general purpose computer;
  • support costs are almost zero - everything is automated;
  • no need to waste money and time to develop and support own solution;
  • a proxy hardware would cost much more to achieve the similar traffic capacity.
