Hi, 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)? Specifically, my question is : 1. Is virtual POP basically a L2VPN? That is, the provider will provide a port at site A,that is somehow connected to LAN of site B ? What's difference with vpop and layer 2 transport then? 2. Do such vPOP have guaranteed latency/bandwidth? 3. Is that really useful? If I'm already buying transit bandwidth/announce my blocks from provider, the site B peers is already going to send traffic through provider's backbone to site A, then what's the difference? Thanks! example 1. http://www.ixreach.com/services/colocation/virtual-pop/ 2. http://www.interoute.com/network-box-virtual-pop-vpop 3. https://www.linx.net/join-linx/vpop
