Autonomous System (Internet)
1 Within the Internet, an 'Autonomous System' ('AS') is a collection of connected Internet
Protocol (IP) routing prefixes under the control of one or more network operators that presents a common, clearly defined routing policy to the
Internet.RFC 1930, Section 3

Autonomous System (Internet) - Types
1 Autonomous Systems can be grouped into three categories,
depending on their connectivity and operating policy.

Autonomous System (Internet) - Types
1 A multihoming|multihomed Autonomous System is an AS that
maintains connections to more than one other AS. This allows the AS to remain connected to the Internet in the event of a complete failure of
one of their connections. However, this type of AS would not allow traffic
from one AS to pass through on its way to another AS.

Autonomous System (Internet) - Types
1 A stub Autonomous System refers to an AS that is connected to only one other AS. This
may be an apparent waste of an AS number if the network's routing policy is the same as its upstream AS's. However, the stub AS may in
fact have peering with other Autonomous Systems that is not reflected in public
Looking Glass Servers|route-view servers. Specific examples include private
interconnections in the financial and transportation sectors.

Autonomous System (Internet) - Types
1 A Internet transit|transit Autonomous System is an AS that provides
connections through itself to other networks. That is, network A can use network B, the transit AS, to connect to network C. If one AS is an ISPs for another, then the former is a transit
AS.

Autonomous system (mathematics)
1 In mathematics, an 'autonomous system' or 'autonomous differential
equation' is a simultaneous equations|system of ordinary
differential equations which does not explicitly depend on the independent variable. When the variable is time, they are also called time-invariant
systems.https://store.theartofservice.com/the-autonomous-system-toolkit.html

Autonomous system (mathematics)
1 Many laws in physics, where the independent variable is usually
assumed to be time, are expressed as autonomous systems because it is
assumed the Physical law|laws of nature which hold now are identical to those for any point in the past or
future.

Autonomous system (mathematics)
1 Autonomous systems are closely related to dynamical systems. Any
autonomous system can be transformed into a dynamical system and, using very weak assumptions, a
dynamical system can be transformed into an autonomous
system.

case, this is the phase line (mathematics)|phase line.
