Abstract

Systems and methods for a conferencing system. Responsive to a new conference request received at a conference orchestration service, participants of the conference and participant regions for each determined participant are determined. A mixer topology is generated that specifies an assignment of each determined participant to at least one input channel of a plurality of mixers. A mixer state manager generates the mixer topology based on the determined participant regions and at least one regional association of a mixer. Media of each determined participant is routed to the assigned at least one input channel according to the generated mixer topology by using the conference orchestration service. The mixer state manager generates the topology responsive to a request provided by the conference state manager. The conference orchestration service receives the generated mixer topology from the mixer state manager via the conference state manager.

First claim

What is claimed is:

1 . A method, comprising: at a conferencing system constructed to operate scalable conferencing services, the conferencing system including a conference orchestration service, a conference state manager, a mixer state manager, and a set of distributed mixers:
receiving a request for a new conference via at least one of application layer interface of the conferencing system and a signaling protocol communication interface of the conference orchestration service; allocating mixers of the conference, the mixers being mixers of the set of distributed mixers; and negotiating media across the allocated mixers, wherein receiving a request for a new conference comprises determining participants of the conference, wherein allocating mixers of the conference comprises:
generating a mixer topology that specifies an assignment of each determined participant to at least one input channel of at least one mixer of the set of distributed mixers,
wherein negotiating media across the allocated mixers comprises routing media of each determined participant to the assigned at least one input channel, and starting the conference, wherein the media is routed according to the generated mixer topology, and wherein the mixer state manager generates the topology responsive to an application layer request provided by the conference state manager, the conference state manager provides the application layer request responsive to an application layer request provided by the conference orchestration service, the routing is performed by the conference orchestration service in accordance with a signaling protocol, and the conference orchestration service receives the generated mixer topology from the mixer state manager via the conference state manager.

2 . The method of claim 1 , wherein the signaling protocol communication interface is a Session Initiation Protocol (SIP) interface.

3 . The method of claim 1 , wherein the conferencing system is a conferencing system of a communication platform, and the conference orchestration service receives the request for the new conference from a call router of the communication platform via the signaling protocol communication interface.

4 . The method of claim 1 , wherein participants include at least one of:
a participant transferred from an established communication session into the conference; a participant that establishes a communication session with an endpoint that is mapped to the conference; and a participant specified by an API request received by the application layer interface of the conferencing system.

5 . The method of claim 1 , wherein allocating mixers of the conference comprises: bridging media of the conference between mixers of the set of distributed mixers.

6 . The method of claim 1 , wherein receiving a request for a new conference comprises determining participant regions of the determined participants.

7 . The method of claim 6 , wherein the conferencing system determines a participant region of a participant based on at least one of an area code and a country code of an endpoint of the participant.

8 . The method of claim 7 , wherein assigning each determined participant to at least one input channel of at least one mixer system of the set of distributed mixers comprises: assigning each determined participant to at least one input channel based on a participant region determined for the participant.

9 . The method of claim 1 , wherein the conference state manager is constructed to maintain conference state of the conference, and to notify the conference orchestration service of conference state changes via the application layer communication interface.

10 . The method of claim 1 , further comprising transitioning the mixer topology according to new conditions.

11 . A method comprising: at a conferencing system constructed to operate scalable conferencing services, the conferencing system including a conference orchestration service, a conference state manager, a mixer state manager, and a set of distributed mixers:
responsive to a request for a new conference that is received via at least one of application layer interface of the conferencing system and a signaling protocol communication interface of the conference orchestration service:
determining participants of the conference and participant regions for each determined participant;
generating a mixer topology by using the mixer state manager, the mixer topology specifying an assignment of each determined participant to at least one input channel of a plurality of mixers of the set of distributed mixers, the mixer state manager generating the mixer topology based on the determined participant regions and at least one regional association of a mixer of the set of distributed mixers; and
routing media of each determined participant to the assigned at least one input channel according to the generated mixer topology by using the conference orchestration service;
wherein the mixer state manager generates the topology responsive to an application layer request provided by the conference state manager, the conference state manager provides the application layer request responsive to an application layer request provided by the conference orchestration service, the routing is performed by the conference orchestration service in accordance with a signaling protocol, and the conference orchestration service receives the generated mixer topology from the mixer state manager via the conference state manager.

12 . The method of claim 11 , wherein the mixer state manager manages mixer state information for each mixer of the set of distributed mixers, and wherein the mixer state information specifies a regional association of at least one mixer of the set of distributed mixers.

13 . The method of claim 12 , wherein for each mixer managed by the mixer state manager, the mixer state information indicates a state for each input channel of the mixer, and wherein the mixer state manager assigns each determined participant to at least one free input channel of a plurality of mixers of the set of distributed mixers, each free input channel being identified by the mixer state information.

14 . The method of claim 11 , wherein determining participants of the conference comprises: identifying participants specified in at least one of an application layer request and an application layer response received via the application layer interface.

15 . The method of claim 11 , wherein determining participants of the conference comprises: identifying participants specified in at least one conference request received via the signaling protocol communication interface of the conference orchestration service.

16 . The method of claim 11 , wherein the mixer state manager assigns each determined participant to at least one input channel based on respective participant priority values.

17 . The method of claim 11 , wherein responsive to an application layer request provided by the conference orchestration service, the conference state manger generates conference state of the conference based on information of the application layer request, and wherein the generated conference state includes the determined participants and the determined participant regions of the participants for the conference.

18 . The method of claim 17 , wherein the conference state is managed by the conference state manager, wherein the conference state manger provides the conference state to the mixer state manager via the application layer request provided by the confere
