Abstract
In the described embodiments, a connection data exchange ('CDX') service serves as an exchange point for connection data for establishing peer-to-peer ('P2P') connections between devices. During operation, the CDX service can receive a connection data structure (a “ticket”) that was created by a matchmaker or an invitation service in response to requests from devices attempting to establish P2P connections. Each ticket can identify a corresponding device and can include encrypted NAT hole-punch data associated with the corresponding device. The CDX service can authenticate each ticket and decrypt the NAT hole punch data from the ticket using a corresponding key. The CDX service can then use corresponding NAT hole punch data to send connection data to each of the devices that reside behind NAT devices.
