The results of our semantic analysis are shown below using the website's language.

They are the main concepts covered by

Each concept has a confidence score. The higher it is, the more important the topic is relative to the page.

Traffic shaping Confidence: 92% Arrow up

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.

Captive portal Confidence: 92% Arrow up

A captive portal is a 'landing' web page, presented by a Layer 3 brand or Layer 2 Operator and shown to users before they gain broader access to URL or http-based Internet services.

Often used to present a landing or log-in page, the portal intercepts observed packets until such time as the user is authorized to launch browser sessions.

After being redirected to a web page which may require authentication, payment, acceptance of EULA/acceptable use policies or other valid credentials that the host and user agree to, the user is granted conditional Internet access.

Captive portals are used for a broad range of mobile and pedestrian broadband services, including cable and commercially provided Wi-Fi, home hotspots and others, and can also be used to provide access to enterprise and residential wired networks (such as apartment houses, hotel rooms, business centers).

Firewall (computing) Confidence: 86% Arrow up

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.

Open-source model Confidence: 84% Arrow up

The open-source model is a decentralized development model that encourages open collaboration.

A main principle of open-source software development is peer production, with products such as source code, blueprints, and documentation freely available to the public.

The open-source movement in software began as a response to the limitations of proprietary code.

The model is used for projects such as in open-source appropriate technologies, and open-source drug discovery.

Intrusion detection system Confidence: 76% Arrow up

An intrusion detection system (IDS) is a device or software application that monitors a network or systems for malicious activity or policy violations.

Any detected activity or violation is typically reported either to an administrator or collected centrally using a security information and event management (SIEM) system.

A SIEM system combines outputs from multiple sources, and uses alarm filtering techniques to distinguish malicious activity from false alarms.
