Internet connectivity options from end-user to tier 3/2 ISPs
An
Internet service provider (
ISP) is an organization that provides services for accessing and using the
Internet. Internet service providers may be organized in various forms, such as commercial,
community-owned,
non-profit, or otherwise
privately owned.
Internet services typically provided by ISPs include
Internet access,
Internet transit,
domain name registration,
web hosting,
Usenet service, and
colocation.

History
The
Internet was developed as a network between government research
laboratories and participating departments of universities. By the late
1980s, a process was set in place towards public, commercial use of the
Internet. The remaining restrictions were removed by 1995, 4 years after
the introduction of the
World Wide Web.
[1]
In 1989, the first ISPs were established in Australia
[2] and the United States. In Brookline, Massachusetts,
The World became the first commercial ISP in the US. Its first customer was served in November 1989.
[3]
On 23 April 2014, the U.S.
Federal Communications Commission
(FCC) was reported to be considering a new rule that will permit ISPs
to offer content providers a faster track to send content, thus
reversing their earlier
net neutrality position.
[4][5][6] A possible solution to net neutrality concerns may be
municipal broadband, according to
Professor Susan Crawford, a legal and technology expert at
Harvard Law School.
[7]
On 15 May 2014, the FCC decided to consider two options regarding
Internet services: first, permit fast and slow broadband lanes, thereby
compromising net neutrality; and second, reclassify broadband as a
telecommunication service, thereby preserving net neutrality.
[8][9] On 10 November 2014, President
Barack Obama recommended that the FCC reclassify broadband Internet service as a telecommunications service in order to preserve
net neutrality.
[10][11][12] On 16 January 2015,
Republicans presented legislation, in the form of a
U.S. Congress H.R. discussion draft bill,
that makes concessions to net neutrality but prohibits the FCC from
accomplishing the goal or enacting any further regulation affecting
Internet service providers.
[13][14] On 31 January 2015,
AP News reported that the FCC will present the notion of applying ("with some caveats")
Title II (common carrier) of the
Communications Act of 1934 to the internet in a vote expected on 26 February 2015.
[15][16][17][18][19] Adoption of this notion would reclassify internet service from one of information to one of the
telecommunications[20] and, according to
Tom Wheeler, chairman of the FCC, ensure
net neutrality.
[21][22] The FCC is expected to enforce net neutrality in its vote, according to the
New York Times.
[23][24]
On 26 February 2015, the FCC ruled in favor of net neutrality by adopting
Title II (common carrier) of the
Communications Act of 1934 and
Section 706 in the Telecommunications Act of 1996 to the Internet.
[25][26][27] The FCC Chairman,
Tom Wheeler, commented, "This is no more a plan to regulate the Internet than the
First Amendment is a plan to regulate free speech. They both stand for the same concept."
[28]
On 12 March 2015, the FCC released the specific details of the net neutrality rules.
[29][30][31] On 13 April 2015, the FCC published the final rule on its new "
Net Neutrality" regulations.

Classifications
Access providers ISP
ISPs provide
Internet access, employing a range of technologies to connect users to their network.
[34] Available technologies have ranged from computer modems with
acoustic couplers to telephone lines, to television cable (CATV), wireless Ethernet (wi-fi), and fiber optics.
For users and small businesses, traditional options include copper wires to provide
dial-up, DSL, typically
asymmetric digital subscriber line (ADSL),
cable modem or
Integrated Services Digital Network (ISDN) (typically
basic rate interface). Using
fiber-optics to end users is called
Fiber To The Home or similar names.
[35]
For customers with more demanding requirements (such as
medium-to-large businesses, or other ISPs) can use higher-speed DSL
(such as
single-pair high-speed digital subscriber line),
Ethernet,
metropolitan Ethernet,
gigabit Ethernet,
Frame Relay, ISDN
Primary Rate Interface,
ATM (Asynchronous Transfer Mode) and
synchronous optical networking (SONET).
[36]
Wireless access is another option, including
cellular and
satellite Internet access.
Mailbox providers
A
mailbox provider
is an organization that provides services for hosting electronic mail
domains with access to storage for mail boxes. It provides
email servers to send, receive, accept, and store email for
end users or other organizations.
Many mailbox providers are also access providers,
[37] while others are not (e.g.,
Yahoo! Mail,
Outlook.com,
Gmail,
AOL Mail,
Po box). The definition given in
RFC 6650 covers
email hosting services,
as well as the relevant department of companies, universities,
organizations, groups, and individuals that manage their mail servers
themselves. The task is typically accomplished by implementing
Simple Mail Transfer Protocol (SMTP) and possibly providing access to messages through
Internet Message Access Protocol (IMAP), the
Post Office Protocol,
Webmail, or a proprietary protocol.
[38]
Hosting ISPs
Internet hosting services provide email, web-hosting, or online storage services. Other services include
virtual server, cloud services, or physical server operation.
Transit ISPs
Tiers 1 and 2 ISP interconnections
Just as their customers pay them for Internet access, ISPs themselves
pay upstream ISPs for Internet access. An upstream ISP usually has a
larger network than the contracting ISP or is able to provide the
contracting ISP with access to parts of the Internet the contracting ISP
by itself has no access to.
[39]
In the simplest case, a single connection is established to an
upstream ISP and is used to transmit data to or from areas of the
Internet beyond the home network; this mode of interconnection is often
cascaded multiple times until reaching a
tier 1 carrier. In reality, the situation is often more complex. ISPs with more than one
point of presence
(PoP) may have separate connections to an upstream ISP at multiple
PoPs, or they may be customers of multiple upstream ISPs and may have
connections to each one of them at one or more point of presence.
[40] Transit ISPs provide large amounts of
bandwidth for connecting hosting ISPs and access ISPs.
[41]
Virtual ISPs
A
virtual ISP (VISP) is an operation that purchases services from another ISP, sometimes called a
wholesale ISP in this context,
[42]
which allow the VISP's customers to access the Internet using services
and infrastructure owned and operated by the wholesale ISP. VISPs
resemble
mobile virtual network operators and
competitive local exchange carriers for voice communications.
Free ISPs
Free
ISPs are Internet service providers that provide service free of
charge. Many free ISPs display advertisements while the user is
connected; like commercial
television, in a sense they are selling the user's attention to the advertiser. Other free ISPs, sometimes called
freenets, are run on a nonprofit basis, usually with volunteer staff.
[citation needed]
Wireless ISP
A
wireless Internet service provider
(WISP) is an Internet service provider with a network based on wireless
networking. Technology may include commonplace Wi-Fi wireless mesh
networking, or proprietary equipment designed to operate over open
900 MHz, 2.4 GHz, 4.9, 5.2, 5.4, 5.7, and 5.8 GHz bands or licensed
frequencies such as 2.5 GHz (EBS/BRS), 3.65 GHz (NN) and in the UHF band
(including the MMDS frequency band) and LMDS.
[citation needed]
Peering
ISPs may engage in
peering, where multiple ISPs interconnect at
peering points or
Internet exchange points
(IXs), allowing routing of data between each network, without charging
one another for the data transmitted—data that would otherwise have
passed through a third upstream ISP, incurring charges from the upstream
ISP.
[39]
ISPs requiring no upstream and having only customers (end customers and/or peer ISPs) are called
Tier 1 ISPs.
Network hardware, software and specifications, as well as the
expertise of network management personnel are important in ensuring that
data follows the most efficient route, and upstream connections work
reliably. A tradeoff between cost and efficiency is possible.
[citation needed]
Law enforcement and intelligence assistance
Internet service providers in many countries are legally required (e.g., via
Communications Assistance for Law Enforcement Act (CALEA) in the U.S.) to allow
law enforcement
agencies to monitor some or all of the information transmitted by the
ISP. Furthermore, in some countries ISPs are subject to monitoring by
intelligence agencies. In the U.S., a controversial
National Security Agency program known as
PRISM
provides for broad monitoring of Internet users traffic and has raised
concerns about potential violation of the privacy protections in the
Fourth Amendment to the United States Constitution.
[43][44] Modern ISPs integrate a wide array of
surveillance and
packet sniffing equipment into their networks, which then feeds the data to law-enforcement/intelligence networks (such as
DCSNet in the United States, or
SORM[45] in Russia) allowing monitoring of Internet traffic in real time.
