摘要:
Architecture for a session lock and lobby feature in a distributed conferencing framework for a conferencing session. Under a lock scenario, once a user enters the session, the session can be locked to prevent other individuals from entering, even if the individuals were invited to the session. Locking can be accomplished manually by a session participant and/or automatically based on criteria. The lobby feature allows a session participant to be aware of users in the lobby and pending access to the session by providing notification and/or identification of the user attempting to gain access. The session leader can selectively allow access to the session. The architecture facilitates lock and lobby features in multiple identical, leaderless, conference servers which together form a distributed conferencing system. The lock and lobby features can employ media session protocols such as session initiation protocol (SIP) and centralized conference control protocol (C3P).

An existing primary data copy can be maintained on an existing primary front end server node. One or more existing secondary data copies can be maintained on one or more existing secondary front end server nodes to minor the existing primary data copy (such as by making synchronous changes to the secondary data copies). One or more existing backup data copies can be maintained on an existing backend server node to mirror the existing primary data copy (such as by making asynchronous changes to the one or more backup data copies). The existing backend server node can be accessible by one or more of the front end nodes. In response to detecting a failure of the existing primary data copy, one of the one or more secondary data copies can be designated as a new primary data copy in place of the existing primary data copy.

Systems and methods that enable conference unaware clients to participate in the conference. A conferencing component is aware of what protocol to employ, and enables devices and/or end points that employ disparate or heterogeneous protocols to participate in the same conference initiated therebetween. A call flow (e.g., in form of a dial out) can be initiated, wherein the conferencing component invites conference unaware devices to participate in the conference.

Endpoint crashes in a real time communication system are detected by a home server providing presence and other services to the endpoint upon receipt of an error message from an access server between the endpoint and the home server. The home server uses a cookie inserted into a dialog between itself and the endpoint identifying the endpoint, a session state created by the access server identifying the endpoint, or a transaction state maintained by the home server to look up the endpoint associated with the error message. Race conditions occurring when an endpoint crashes and recovers rapidly can be avoided employing a timestamp or sequence number incremented for each new endpoint registration and comparing a current timestamp or sequence number to the stored one before updating records at the home server. By notifying other subscribers about crashed endpoints, routing fidelity is enhanced.

Architecture that facilitates management and control of sidebar sessions (or breakout rooms) in a distributed conferencing environment. Distributed frontends (or MCUs) are provided for multi-party access into a main conferencing session. In one implementation, the main session can then be partitioned to provide one or more sidebar sessions for side conferencing. The sidebar sessions can all be contained on a single MCU or distributed across multiple MCUs. The leader of the main session can then freely roam among the sidebar sessions of a single MCU or among the sessions on the distributed MCUs. The protocol can be SIP-based, and also or alternatively use C3P commands for creating (or adding) a sidebar session, modifying the sidebar, moving users to and from a sidebar, and deleting the sidebar session.

This document describes tools that enable fault-tolerant resource committal for a system having computing devices needing to have operations of a particular type performed by one of multiple external resources. The tools may do so without relying on leadership from a pre-selected or altered computing device. Assume, for example, that the system is a conferencing system, the computing devices are front-end servers, the operations of a particular type are those that require handling of audio from users in the conference, and the external resources are homogeneous audio multi-point control units (MCUs) each of which is capable of handling audio from all of the users. The tools may enable, in one embodiment, any of the front-end servers to allocate a single audio MCU and commit all of the other front-end servers to use that single MCU for their audio operations.
