Connectivity candidate filtering
In accordance with one disclosed method, a first application may receive a first connectivity candidate from a second application, the first connectivity candidate identifying at least a first internet protocol (IP) address that a remote application can potentially use to send data over a network to the second application for use by the first application. The first application may determine that the first connectivity candidate satisfies at least one criterion and, based at least in part on the first connectivity candidate satisfying the at least one criterion, may cause the first connectivity candidate to be sent to the remote application via a signaling channel to cause the remote application to attempt to use the first connectivity candidate to send data to the second application via the network.
1 . A system, comprising:
at least one processor; and
at least one non-transitory computer-readable medium encoded with instruction which, when executed by the at least one processor, cause the system to:
receive, by a first application executable on the system, a first interactive connectivity establishment (ICE) candidate from a second application hosted on the system;
determine, by the first application, that a first value of a first attribute of a first ICE candidate does not match a predetermined value, wherein the first attribute is an internet protocol address type or a transport protocol type;
based at least in part on the first value not matching the predetermined value, cause, by the first application, the first ICE candidate to be sent to a remote application via a signaling channel to cause the remote application to attempt to use the first ICE candidate to send data to the second application via a network;
receive, by the first application, a second ICE candidate from the second application;
