Traffic shaping (also known as packet shaping) is a computer network traffic management technique which delays some or all datagrams to bring them into compliance with a desired traffic profile.

Traffic shaping is used to optimize or guarantee performance, improve latency, and/or increase usable bandwidth for some kinds of packets by delaying other kinds.

It is often confused with traffic policing, the distinct but related practice of packet dropping and packet marking.

Linux (pronounced or, less frequently) is a Unix-like computer operating system assembled under the model of free and open-source software development and distribution.

The defining component of Linux is the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds.

In computing, a firewall is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules.

A firewall typically establishes a barrier between a trusted, secure internal network and another outside network, such as the Internet, that is assumed not to be secure or trusted.

Firewalls are often categorized as either network firewalls or host-based firewalls.

Network firewalls filter traffic between two or more networks; they are either software appliances running on general purpose hardware, or hardware-based firewall computer appliances.

Host-based firewalls provide a layer of software on one host that controls network traffic in and out of that single machine.

Firewall appliances may also offer other functionality to the internal network they protect, such as acting as a DHCP or VPN server for that network.

Configuration management (CM) is a systems engineering process for establishing and maintaining consistency of a product's performance, functional, and physical attributes with its requirements, design, and operational information throughout its life.
