It’s simply extending an exchange vlan over an l2circuit. It works as good as the provider’s network and the intended use for it. As a customer you either want to reach an exchange on a location you’re not at or get a smaller circuit then an exchange would normally sell you directly.
Although you pay the provider that provides you the circuit into the exchange as a reseller, you are a full member there. There’s some controversy in the community on its intended use. Some companies simply use it to get onto an exchange within a metro or country without actually getting kit into an exchange’s POP to save money. Others use it across country borders/oceans and use a high-latency circuit to get onto a local exchange, which defeats some purpose of a local internet exchange. (short low latency-paths into local networks) Then again, getting a circuit from the US into an big exchange like LINX, AMSIX or DECIX can be very appealing on both saving cost of transit and keeping your as-paths (artificially?) short.

I understand it usually involves point-to-multipoint Switched Ethernet with VLANs and resold IX ports. Sounds like a service for ISP that would like to peer, but have relatively small volumes for peering purposes or lopsided volumes.
