# 1. Purpose

Tasks of the control of network streams can arise as on a separate workstation working in any network, and in the big WANs. Thus it is often necessary to know not only loading in the certain direction, but also to allocate from streams definite protocols/services, to have ways to estimate in real time a parity of various traffic. The opportunity of instant reception of such data considerably simplifies localization of problems in large networks and is a necessary source of the information at planning development of networks. TrafficVisor III (further tv3) is the flexible tool that at competent use, can considerably simplify an estimation of a condition and quality of work of a network to raise rigidity of the control over users, services, etc.

## Features of TrafficVisor III:

- Allocation from network streams, based on the set rules, various components by several criteria: the source address, the target address, the protocol, port (UDP, TCP) or type (ICMP) of the protocol.
- Real time statistic.
- Support of the http protocol for installation of rules of the filter and reading of statistics through PIPE or network interfaces.
- Work on a network through the WEB-interface.
- Display of data by means of the Java-client on the user workplaces. Graphic representation of loadings of streams with various charreceiveeristics.
- Work with data in a XML-format.
