Be Unlimited
Be Unlimited (also traded as Be There or simply BE and latterly known legally as Sky Home Communications Limited) was an Internet service provider in the United Kingdom between 2004 and 2014. Initially founded as an independent company by Boris Ivanovic and Dana Tobak in 2005, it was bought by Spanish group Telefónica Europe in 2006 before being sold on to BSkyB in March 2013 in an agreement which saw BSkyB buy the fixed telephone line and broadband business of Telefónica Europe which at the time traded under the O2 and BE brands. The deal saw BSkyB agree to pay £180 million initially, followed by a further £20 million after all customers had been transferred to Sky's existing business. The sale was subject to regulatory approval in April 2013, and was subsequently approved by the Office of Fair Trading on 16 May 2013. BE offered ADSL2+ broadband services through BT's telephone exchanges via Local Loop Unbundling (LLU), with advertised speeds of up to 16 Mbit/s dow ...

Internet Service Provider
An Internet service provider (ISP) is an organization that provides a myriad of services related to accessing, using, managing, or participating in the Internet. ISPs can be organized in various forms, such as commercial, community-owned, non-profit, or otherwise privately owned. Internet services typically provided by ISPs can include internet access, internet transit, domain name registration, web hosting, and colocation. History The Internet (originally ARPAnet) was developed as a network between government research laboratories and participating departments of universities. Other companies and organizations joined by direct connection to the backbone, or by arrangements through other connected companies, sometimes using dialup tools such as UUCP. By the late 1980s, a process was set in place towards public, commercial use of the Internet. Some restrictions were removed by 1991, shortly after the introduction of the World Wide Web. During the 1980s, online s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upstream (networking)
In computer networking, upstream refers to the direction in which data can be transferred from the client to the server ( uploading). This differs greatly from downstream not only in theory and usage, but also in that upstream speeds are usually at a premium. Whereas downstream speed is important to the average home user for purposes of downloading content, uploads are used mainly for web server applications and similar processes where the ''sending'' of data is critical. Upstream speeds are also important to users of peer-to-peer software. ADSL Asymmetric digital subscriber line (ADSL) is a type of digital subscriber line (DSL) technology, a data communications technology that enables faster data transmission over Copper wire, copper telephone lines than a conventional voiceband modem ... and cable modems are asymmetric, with the upstream data rate much lower than that of its downstream.

Telephone Line
A telephone line or telephone circuit (or just line or circuit industrywide) is a single-user circuit on a telephone communication system. It is designed to reproduce speech of a quality that is understandable. It is the physical wire or other signaling medium connecting the user's telephone apparatus to the telecommunications network, and usually also implies a single telephone number for billing purposes reserved for that user. Telephone lines are used to deliver consistent landline telephone service and digital subscriber line (DSL) phone cable service to the premises. Telephone overhead lines are connected to the public switched telephone network. The voltage at a subscriber's network interface is typically 48 V between the ring and tip wires, with tip near ground and ring at –48 V. In the United States In 1878, the Bell Telephone Company began using two-wire circuits, called the local loop, from each user's telephone to end offices, which performed a ...

Terabyte
The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures. To disambiguate arbitrarily sized bytes from the common 8-bit definition, network protocol documents such as the Internet Protocol () refer to an 8-bit byte as an octet. Those bits in an octet are usually counted with numbering from 0 to 7 or 7 to 0 depending on the bit endianness. The size of the byte has historically been hardware-dependent and no definitive standards existed that mandated the size. Sizes from 1 to 48 bits have been used. The six-bit character code was an often-used implementation in early encoding systems, and computers using six-bit and nine-bit bytes were common in the 1960s. These systems often had memory words of 12, 18, 24, 30, 36, 48, or 60 bits, corresponding ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London Internet Exchange
The London Internet Exchange (LINX) is an Internet exchange point (IXP) providing peering to over 950 different autonomous systems (ASNs).

Acceptable Use Policy
An acceptable use policy (AUP)—also referred to as an acceptable usage policy or, in certain commercial contexts, a fair use policy (FUP)—is a formal set of guidelines established by the administrator, proprietor, or operator of a computer network, website, digital platform, or information system. The policy delineates the conditions under which access is granted and specifies the behaviors that are permitted, restricted, or prohibited. AUPs function as regulatory instruments intended to ensure the responsible use of information and communications technology, to mitigate institutional liability, and to safeguard the rights and security of both users and system owners. The term “fair use policy,” though occasionally employed in industry settings (e.g., by internet service providers to define usage thresholds), is conceptually distinct from fair use as defined in copyright law. The latter constitutes a statutory doctrine governing the lawful reproduction and transforma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bandwidth Management
Bandwidth management is the process of measuring and controlling the communications (traffic, packets) on a network link, to avoid filling the link to capacity or overfilling the link,https://www.internetsociety.org/wp-content/uploads/2017/08/BWroundtable_report-1.0.pdf Internet Society on Bandwidth Management which would result in network congestion and poor performance of the network. Bandwidth is described by bit rate and measured in units of bits per second (bit/s) or bytes per second (B/s). Bandwidth management mechanisms and techniques Bandwidth management mechanisms may be used to further engineer performance and includes: * Traffic shaping (rate limiting): **Token bucket **Leaky bucket ** TCP rate control - artificially adjusting TCP window size as well as controlling the rate of ACKs being returned to the sender * Scheduling algorithms: ** Weighted fair queuing (WFQ) ** Class based weighted fair queuing ** Weighted round robin (WRR) ** Deficit weighted round robin (DWRR ...

SpeedTouch
SpeedTouch (originally Speed Touch) is a discontinued product line of customer-premises equipment that was initially produced by Alcatel and later by Thomson Multimedia. It includes ADSL and ADSL2+ modems, residential gateways, wireless access equipment, VoIP handsets and SHDSL equipment for Interconnection, interconnections. History In June 2001, a memorandum of understanding was signed between Alcatel and Thomson Multimedia to sell the DSL business for 456 million euros paid in new shares to Thomson. The SpeedTouch brand was discontinued by in 2009 when the devices were rebranded as "Thomson Gateway". Models Security SpeedTouch gateways have been criticized because the algorithm used by the manufacturer to set both the default SSID and the corresponding WEP/WPA-PSK/WPA2-PSK passwords was very easily compromised, meaning that wireless access to SpeedTouch models that still use the default password is easily possible. In 2002 San Diego Supercomputer Center of the University ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
