-====== What is a Network Operator ======
-A network operator is an entity which is running a TCP/IP based network infrastructure, providing access to:
-  * **end users**: these end users could be residential, businesses, content developers and hosts, educational institutions, charities, government departments, and so on. The Internet operations and peering communities call these end-users "//eyeballs//".
-  * **other network operators**: the Internet is hierarchical and some network operators only provide Internet access to other network operators; others may also provide Internet access to **end users** as well.
-Network operators have a number of important goals to make their existence sustainable (whether as a commercial entity or a Research & Education network).
-These goals are:
-  * [[what-is-peering/what_is_a_network_operator#internet_resources|Internet Resources]]
-  * [[what-is-peering/what_is_a_network_operator#access|Access]]
-  * [[what-is-peering/what_is_a_network_operator#peering|Peering]]
-  * [[what-is-peering/what_is_a_network_operator#transit|Transit]]
-  * [[what-is-peering/what_is_a_network_operator#costs|Costs]]
-===== Internet Resources =====
-A network operator will have their **own** Internet resources, namely their **own** IP address space (IPv4 or IPv6 or both) and their **own** Autonomous System number (the globally unique identifier for their network as used by the Border Gateway Protocol (BGP), the routing protocol of the Internet).
-Entities without their own Internet resources are not considered network operators for the purposes of this toolbox as they cannot participate in the activities being described here without those independent resources.
-Internet resources are obtainable from the Regional Internet Registries ([[https://www.afrinic.net/|AfriNIC]], [[https://apnic.net|APNIC]], [[https://www.arin.net/|ARIN]], [[https://www.lacnic.net/|LACNIC]], [[https://www.ripe.net/|RIPE NCC]]) and their websites should be consulted for further information about membership and obtaining resources.
-===== Access =====
-The primary goal of a network operator is to provide Internet access to their users or customers (be these end-users or other network operators).
-The vast majority of content consumed by Internet users today is made up of social media and videos. This content is distributed by the multi-national content providers and content distribution networks.
-To provide the highest bandwidth and highest quality access to this content, a network operator positions their network as close as possible to the content providers. There are two ways of doing this: [[what_is_a_network_operator#peering|peering]], and [[what_is_a_network_operator#peering|transit]].
-===== Peering =====
-Peering is the connection of one network operator to another network operator to exchange traffic originated by each network operator.
-The vast majority of peering does not attract traffic charges - it is known as "settlement-free peering".
-Peering can take place in two forms:
-  - [[peering-toolbox/where-to-peer#private_peering|Private peering]] is where there is a private connection between the two network operators for the purpose of exchanging traffic.
-  - [[peering-toolbox/where-to-peer#public_peeringinternet_exchange_point|Public peering]] takes place at a public peering point, commonly known as an [[what-is-peering/what_is_an_internet_exchange_point|Internet Exchange Point]].
-Peering is described in more detail in the [[what-is-peering/what_is_peering|What is Peering]] page.
-===== Transit =====
-Transit is the purchasing of Internet access by a network operator from another network operator (known as their upstream provider).
-The vast majority of transit attracts traffic charges, with charges being levied on traffic levels (typically measured in US$ per Mbps), rather than outright volume (as still happens in a few locations).
-===== Costs =====
-Network Operators strive to minimise the cost of access to the content their end users demand.
-Transit costs money, peering does not (after the initial set-up), which means that network operators strive to peer as much as possible. Transit is considered a last resort, only to be used for low volume content sources or other destinations which cannot be reach by peering.
-It is estimated today that around 80% of all traffic for a typical access provider can be obtained by peering. (This is based on observations of real traffic profiles by the author.)
