CARRIER NEUTRAL DATA CENTRE
A carrier neutral data centre is typically not owed or operated by a telco or carrier,
instead the facility is owned by a data centre provider who encourages multiple telcos
to be present in the facility and offer competing services to the customers leasing
space. This offers the major benefits of choice and flexibility for selecting from
a wide range of telecoms and connectivity suppliers present.
TIER-1 NETWORK
An often misused term, "tier-1" describes a connectivity provider who owns all their
own network infrastructure and does not need to purchase transit connectivity from
other providers to reach any destinations. This puts the provider in the
advantageous position of having full control over their network connectivity to
all destinations.
BGP ROUTING
BGP is a routing protocol used to connect internet networks to multiple connectivity
providers and automatically re-route traffic via alternate paths. It benefits
service providers to be able to switch and re-route their traffic via different
connectivity suppliers without changing IP address numbering.
ON-NET POP
"On-net" is often used to describe a building where the connectivity provider has
their own PoP (Point of Presence) and equipment within the building. Commonly
in the US, due to geographical distance, some data centres will bring in their
connectivity over leased circuits from the nearest provider PoP rather than the
provider having their own on-site presence. On-net PoPs serving a large number
of customers tend to be more resiliently designed and connected than individual
leased circuits.
