The Internet is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the interlinked hypertext documents and applications of the World Wide Web (WWW), electronic mail, internet telephony, and file sharing.
Peer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers. Peers are equally privileged, equipotent participants in the network, forming a peer-to-peer network of nodes. In addition, a personal area network (PAN) is also in nature a type of decentralized peer-to-peer network typically between two devices.
An anonymous P2P communication system is a peer-to-peer distributed application in which the nodes, which are used to share resources, or participants are anonymous or pseudonymous. Anonymity of participants is usually achieved by special routing overlay networks that hide the physical location of each node from other participants.
Deep packet inspection (DPI) is a type of data processing that inspects in detail the data being sent over a computer network, and may take actions such as alerting, blocking, re-routing, or logging it accordingly. Deep packet inspection is often used for baselining application behavior, analyzing network usage, troubleshooting network performance, ensuring that data is in the correct format, checking for malicious code, eavesdropping, and internet censorship, among other purposes. There are multiple headers for IP packets; network equipment only needs to use the first of these for normal operation, but use of the second header is normally considered to be shallow packet inspection despite this definition.
Internet traffic is the flow of data within the entire Internet, or in certain network links of its constituent networks. Common traffic measurements are total volume, in units of multiples of the byte, or as transmission rates in bytes per certain time units.
Network neutrality, often referred to as net neutrality, is the principle that Internet service providers (ISPs) must treat all Internet communications equally, offering users and online content providers consistent transfer rates regardless of content, website, platform, application, type of equipment, source address, destination address, or method of communication. Net neutrality was advocated for in the 1990s by the presidential administration of Bill Clinton in the United States. Clinton's signing of the Telecommunications Act of 1996, an amendment to the Communications Act of 1934, set a worldwide example for net neutrality laws and the regulation of ISPs.
Bandwidth throttling consists in the limitation of the communication speed, of the ingoing (received) or outgoing (sent) data in a network node or in a network device such as computers and mobile phones.
Internet censorship is the legal control or suppression of what can be accessed, published, or viewed on the Internet. Censorship is most often applied to specific internet domains but exceptionally may extend to all Internet resources located outside the jurisdiction of the censoring state. Internet censorship may also put restrictions on what information can be made internet accessible. Organizations providing internet access – such as schools and libraries – may choose to preclude access to material that they consider undesirable, offensive, age-inappropriate or even illegal, and regard this as ethical behavior rather than censorship. Individuals and organizations may engage in self-censorship of material they publish, for moral, religious, or business reasons, to conform to societal norms, political views, due to intimidation, or out of fear of legal or other consequences.
Hart v. Comcast was a suit filed by Jon Hart, a citizen of California against Comcast in Alameda County. Comcast is a provider of internet access and services. The suit alleged that Comcast was illegally interfering with certain types of internet traffic, such as BitTorrent. The suit alleged that Comcast is guilty of false advertising for advertising high speed services yet deliberately using technology to interfere with access speeds. The suit also claimed Comcast's actions violated established Federal Communications Commission policies on Net Neutrality. The case has since been settled out of court.
Peer-to-peer caching is a computer network traffic management technology used by Internet Service Providers (ISPs) to accelerate content delivered over peer-to-peer (P2P) networks while reducing related bandwidth costs.
File sharing is the practice of distributing or providing access to digital media, such as computer programs, multimedia, documents or electronic books. Common methods of storage, transmission and dispersion include removable media, centralized servers on computer networks, Internet-based hyperlinked documents, and the use of distributed peer-to-peer networking.
Founded in 2004 in New York City, Pando Networks was a managed peer-to-peer (P2P) media distribution company backed by Intel Capital, BRM Capital and Wheatley Partners. The company specialized in cloud distribution of games, video and software for publishers and media distributors and also operated a freemium consumer business for sending large files.
A TCP reset attack, also known as a forged TCP reset or spoofed TCP reset, is a way to terminate a TCP connection by sending a forged TCP reset packet. This tampering technique can be used by a firewall or abused by a malicious attacker to interrupt Internet connections.
Blue Coat Systems, Inc., was a company that provided hardware, software, and services designed for cybersecurity and network management. In 2016 it was acquired by and folded into Symantec and in 2019 as part of Symantec’s Enterprise Security business it was sold to Broadcom.
Internet censorship circumvention is the use of various methods and tools to bypass internet censorship.
Procera Networks is a networking equipment company based in Fremont, California, United States, that designs and sells Network Intelligence solutions based on deep packet inspection (DPI) technology. Procera sells solutions to telecom operators, governments, enterprises, and network equipment vendors in the areas of Analytics, Traffic Management, Policy and Charging Control, and Service Provider Compliance.
Traffic classification is an automated process which categorises computer network traffic according to various parameters into a number of traffic classes. Each resulting traffic class can be treated differently in order to differentiate the service implied for the data generator or consumer.
Net bias is the counter-principle to net neutrality, which indicates differentiation or discrimination of price and the quality of content or applications on the Internet by ISPs. Similar terms include data discrimination, digital redlining, and network management.
A number of different controversies and criticisms have surrounded Comcast for various reasons over its recent history. Customers of the telecommunications company report low levels of customer satisfaction on both service and cost. Comcast has also had several customer service scandals, the most notorious of which featured a representative not allowing a customer to cancel his service. This clip went viral. Comcast has also been widely criticized, most publicly by Netflix, for its position against net neutrality, the principle that all traffic on the internet should be treated equally.
Domain fronting is a technique for Internet censorship circumvention that uses different domain names in different communication layers of an HTTPS connection to discreetly connect to a different target domain than that which is discernable to third parties monitoring the requests and connections.
