I came across the idea of the virtual POP , but the website for them have way too much jargon to me[1][2][3], can someone explain it like i'm five (:-D)?
A virtual Point Of Presence means that you provide services at a location via someone else's facilities. The classic example was extending a PRI for dialup modems inside a particular local calling area via a point-to-point T1 back to your modem bank somewhere else that would have been a long distance call for those customers. If you put a modem bank in their local calling area, it's a POP. If you extend the circuit from their local calling area back to your modem bank elsewhere, it's a virtual POP. Modern examples of virtual POPs are much fancier but it's the same basic idea.
1. Is virtual POP basically a L2VPN?
It can be. Depends on what service you're extending from the "virtual" location.
2. Do such vPOP have guaranteed latency/bandwidth?
Depends on what you're extending and how.
3. Is that really useful?
It can be. It can let you dip your toes in a market without a large up-front investment in equipment and backhaul. Regards, Bill Herrin -- William Herrin ................ herrin@dirtside.com bill@herrin.us Owner, Dirtside Systems ......... Web: <http://www.dirtside.com/>
