Traffic shaping
Traffic shaping is an attempt to control computer network
traffic in order to optimize or guarantee performance, low latency,
and/or bandwidth. Traffic shaping deals with concepts of
classification, queue disciplines, enforcing policies, congestion
management.
Traffic shaping provides a mechanism
to control the volume of traffic being sent into a network, and the
rate at which the traffic is being sent rate limiting. NeT Firewall
also identifies traffic flows for different network services that
allows the traffic-shaping control mechanism to separate traffic
into individual flows and shape them differently.
Traffic Shaping Filter
Terms
Filter description is a human readable line of text
intended to provide description of a Filter and what packets it
applies to.
Filteridentifier (or Filter priority) is a numeric value
within the range of 1 to 65535. The smaller is the priority value
of a Filter, the higher is its priority and the faster it will be
applied when analyzing packets.
Network interface is a network adapter that receives
the packets that are analyzed basing on a Filter.
Common Rate defines average traffic rate in bytes
per second.
Peak Rate defines peak traffic rate in bytes per
second.
According to protocol, the Filter is applied to the
packets with the same protocol only.
Source IP-address and port - control over
packets with given source defined by Filter.
Destination IP-address and port -
control over packets with given destination defined by
Filter.
Note
- To create new Filter right-click
Traffic Shaper on the program tree and choose
New Traffic Shaper Filter. Then
fill in required properties.
- The Port term applies to TCP and UDP
network protocols only.
Important
- You can enable, disable or delete Filters.
- Only outgoing traffic can be controlled by NeT Firewall.
- It is important to determine the order of Shaper
Filters, when developing computer shaping policy.
