Terminology

The following table lists and describes the key terms used in this document.

Term	Definition
Autonomous System number (ASN)	An Autonomous system number or ASN is used in the Internet to identify either a single network or a group of networks managed and controlled by a common network administrative entity (which could be an Internet Service Provider, a business enterprise, an institute for example). An autonomous system is a routing domain that is managed by the network administrator of that domain. The autonomous system is assigned a globally unique number that is referred to as the Autonomous System Number (ASN). See http://www.iana.org/assignments/as-numbers/as-numbers.xhtml.
Border Gateway Protocol (BGP)	The protocol that’s used to share routing information between two networks. See http://tools.ietf.org/html/rfc4271.
Colocated data center	When your data center and Oracle data center share common facilities at a FastConnect location.
Cross Connects	In the colocation scenario, cross connects are physical cables which connect your existing network to Oracle at a FastConnect location.
FastConnect location	A specific Oracle data center where your Oracle Cloud services are provisioned and FastConnect Classic is available at this location. When you provision FastConnect Classic at a particular location you can only access the Oracle Cloud services that are provisioned at that location. For example, to access an Oracle Cloud service that is provisioned at the Chicago data center, you'll provision FastConnect Classic at Chicago.
Internet Routing Registry (IRR)	The IRR provides a mechanism for mapping an origin AS number to a list of networks or validating the contents of BGP announcement messages. See https://www.arin.net/resources/routing/.
LC connector	A type of fiber optic connector. See http://www.thefoa.org/tech/connID.htm.
Letter of Authorization (LOA)	Letter of authorization provides details that are required to set up cross connects between your network routers and Oracle routers.
Network Address Translation (NAT)	Network address translation (NAT) is a method of remapping one IP address space into another by modifying network address information in Internet Protocol (IP) datagram packet headers while they are in transit across a traffic routing device. See https://www.ietf.org/proceedings/43/I-D/draft-ietf-nat-terminology-01.txt.
Private peering	Peering established with FastConnect Classic edge routers, over which typically private (RFC1918) IP prefixes are advertised.
Public peering	Peering established with FastConnect Classic edge routers, over which public IP prefixes are advertised. Public IP prefixes that are registered with IRR or RIR are publicly routable over the Internet.
Remote data center	When your data center is not colocated with an Oracle data center.
Regional Internet Registry (RIR)	RIRs administer and register IP addresses and ASN numbers within a region. See https://www.arin.net/resources/routing/.
Throughput	The number of gigabits of data that can be sent per second (Gbps) or megabits per second (Mbps) through FastConnect Classic.
