my company has license to provide IXP sevices, It is quite new to us. I just know IXP can provide colocation, data center. what other services can an IXP can provide? anybody knows this, please advice me. Thanks!
Practically anything that "can" be provided in a commercial data-center - can be provided by you to your potential clients. Since you mentioned "license", you are presumably in a country with more stringent regulations with respect to IP services, etc. You may want to check with the authority that issued the license to know more about what you can and cannot provide. For example, are you allowed to provide ISP services? VoIP gateways, Telco co-locations, ATM services servers? etc. etc.
