1. Let me tell you today what is a PoP point?
On a computer network, a point-of-presence (PoP) indicates an incoming Point. The PoP point is located outside the edge of the enterprise network. It is the entry point to access the enterprise network. Services provided by the outside world, including Internet access, wide area connection and telephone service (PSTN), are accessed through the PoP point.
In an enterprise, a PoP point provides links to external services and sites. The PoP point can be directly connected to one or more Internet service providers (ISPs). In this way, internal users of the enterprise can access the Internet through these links. The enterprise‘s remote sites are also connected through PoP points, and the wide area link between these remote sites is established by the service provider.
2. PoP points must have a unique IP address
For an ISP (Internet Service Provider), a PoP is a point of presence that connects the Internet from one place to another. Every PoP must have a unique Internet Protocol (IP) address. This IP address is like a house number, and visitors can find the exact entrance through the house number.
3. The number of PoP points is a measure of the development of service providers.
An ISP (Internet Service Provider) or OSP (Online Service Provider) has one or several points of presence on the Internet. The number of points of presence is a measure of the size and growth rate of a service provider.
4. The closer the PoP point is, the higher the bandwidth guarantee
Generally, the closer the distance between PoP points, the smaller the line signal loss, and the higher the bandwidth guarantee for connected users.
5. What device will configurate in the PoP sites to help access to transmission network?
DWDM platform, Full Optic Ports Switch, Core router so on.
