Shaper Control Tool

Administration tool for Linux-based traffic shaper

Linux layer 7 packet classifier

l7-filter is an application layer packet classifier that can differentiate types of network traffic by protocol; for example it can identify bittorrent, IRC, SIP and many other types of traffic. In turn, these classifiers can be used to block or shape traffic according to a defined network policy.

Bandwidth Management Tools

In short, a very powerfull firewall configuration utility. Originally designed for Linux based routers, but now supports basically any type of system. Supports easy to use XML based configuration of firewall, traffic shaping, traffic logging and robust traffic graphing.

toros

Toros is the web interface to easily use the utility TC used for shaping connections based on several parameters. A given IP range or unique IP addresses can be limited to some threshold values which can't be exceeded. Interface also provides a graphical output of the given IP range. //Note ... [More] that TOROS project isn't yet ready for end user. It is still under development. [Less]

TrafficPanel

TrafficPanel provides full-featured management of web traffic flows in a company's network through gateway. This is web application to manage different Linux tools from your browser, this is an extendible opensource solution for complex traffic management that allows setting maximal amount of ... [More] transferred data, setting traffic priority, blocking http traffic of inappropriate web resources and many other features. TrafficPanel architecture is based on modules around a TrafficPanel kernel and because of open source and strong kernel API new custom required modules will be developed in later. [Less]

pspacer

PSPacer (Precise Software Pacer) is a qdisc kernel module which realizes precise transmission bandwidth control. It makes bursty traffic which is often generated by TCP smooth without any special hardware. Bursty traffic can degrade the communication performance, because it causes buffer overflow ... [More] at intermediate network nodes and results in packet losses. In a bursty traffic, packets are sent back to back. By adding a short pause in between the packets, traffic bursts can be avoided. PSPacer controls the interval between outgoing packets very precisely. The key idea of PSPacer is to determine transmission timing of packets by the number of bytes transferred. If packets are transferred back to back, the timing a packet is sent can be determined by the number of bytes sent before the packet. PSPacer fills the gaps between time aligned "real packets" (the packets which are sent by user program) by "gap packets". The real packets and gap packets are sent back to back, and thus the timing of transmission of each real packet can be precisely controlled by adjusting the gap packet size. As the gap packets, the IEEE 802.3x PAUSE frames are used. PAUSE frames are discarded at a switch input port, and only real packets go through the switch keeping the original intervals. In the past, some software-based pacing schemes have been proposed. These schemes use timer interrupt based packet transmission timing control. Therefore, to achieve precise pacing, they require the operating system to maintain a high resolution timer, which could incur a large overhead. [Less]

nf-hishape

nf-HiShape is a kernel module for traffic shaping according to the source ip address. It limits the bandwidth usage of user-defined ip-address ranges and was implemented by the constraint of high-performance operation as well as easy usage. The package includes the module itself and a user-land ... [More] tool for its configuration. A demo video of nf-hishape in action can be found here. [Less]
