Abstract:

A conferencing system includes a plurality of ports for network connection to endpoint devices of participants to a conference session. A mixer receives input audio streams from the endpoint devices and then outputs a mixed audio stream back to the endpoint devices. A processor runs a program that automatically downgrades one or more of the participants to the conference session from a full-duplex communication mode to a half-duplex communication mode in response to an event affecting allocation of conferencing resources, the conferencing resources including the ports. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Abstract:

Media relay services are often used to establish sufficiently direct connections in order to enable provisioning of a real-time media service and/or improve the quality of real-time media services. However, media relay services are often gated using authentication systems that add undesirable delay to the delivery and/or access to a real-time media service, which in turn diminish the user experience. By contrast, various implementations disclosed herein include apparatuses, systems, and methods of providing low latency authentication of gated media relay services. For example, in some implementations, a method includes receiving a request for access to a gated media relay service, providing provisional access to the service until an authentication result is available, determining whether the requesting device is authorized to access the media relay service, and at least one of ending or continuing access to the media relay service based on the authentication result.
