What (who) is virtual point of presence - definition

TYPE OF NETWORK BOUNDARY

Point of Presence; Point-of-presence; Points of presence; ISP point of presence

virtual point of presence

(virtual PoP) A point, via which users can connect to an Internet access provider, which is not operated by the provider. The user is charged by the telephone company for the call to the virtual point of presence which relays his call via some third party circuit to the Internet provider's central location. This is in contrast to a physical {point of presence} (PoP) which is operated by the Internet provider themselves. The advantage of a virtual PoP is that the provider can keep all their modems in one location, thus improving availability and maintenance, but users do not have to pay long-distance call charges to that point. (1994-12-13)

An {Internet access provider} may operate several PoPs distributed throughout their area of operation to increase the chance that their subscribers will be able to reach one with a local telephone call. The alternative is for them to use virtual PoPs (virtual points of presence) via some third party. (1994-12-13)

Point of presence

A point of presence (PoP) is an artificial demarcation point or network interface point between communicating entities. A common example is an ISP point of presence, the local access point that allows users to connect to the Internet with their Internet service provider (ISP). A PoP typically houses servers, routers, network switches, multiplexers, and other network interface equipment, and is typically located in a data center. ISPs typically have multiple PoPs. PoPs are often located at Internet exchange points and colocation centres.

In the US, this term became important during the court-ordered breakup of the Bell Telephone system. A point of presence was a location where a long-distance carrier (IXC) could terminate services and provide connections into a local telephone network (LATA).
