Abstract: 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).

Abstract: Architecture for a scalable, pluggable multi-party, and distributed multimedia conferencing. A centralized policy and control conferencing component allows the seamless plug-in of different distributed media components (e.g., data, audio/video, messaging) to accommodate client participation in a conference session. The centralized conference control component includes the following: a conference notification service for accepting subscriptions to the conference state and notifying subscribers about changes to that state; a conference policy and roster control service for storing and manipulating conference policy and rosters; a security service for user authorization/authentication based on user identity information; a scheduling service for conference scheduling; an allocation service for allocating the most available media component(s) for a conference session; and, an MCU management service for conference policy and roster management of the distributed media components.

Abstract: Se describe una arquitectura para una conferencia multimedia escalable, de partes múltiples conectable, y distribuida. Una política centralizada y componente de conferencia de control permiten la conexión uniforme de diferentes componentes de medios distribuidos (por ejemplo, datos, audio/vídeo, transmisión de mensajes) para acomodar participación de cliente en una sesión de conferencia. El componente de control de conferencia centralizado incluye lo siguiente: un servicio de notificación de conferencia para aceptar suscripciones al estado de conferencia y notificar a los suscriptores sobre cambios a ese estado; una política de conferencia y servicio de control de lista para almacenar y manipular política de conferencia y listas; un servicio de seguridad para autorización/autentificación de usuario basado en información de identidad de usuario; un servicio de programación para programación de conferencia; un servicio de distribución para distribuir el componente(s) de medios más disponible para una sesión de conferencia; y, un servicio de manejo de MCU para política de conferencia y manejo de lista de los componentes de medios distribuidos.

Abstract: Protocol architecture for wiring media streams and specifying mixing behavior in a multipoint control unit. The protocol provides the capability to expose the core mixing algorithms to modification for mixing media without dealing with the functionality of the mixer itself (e.g., ports and IP specifics). The protocol facilitates the wiring of input media streams to output media streams by changing the mixing behavior via changes to the mixing algorithms using the protocol. The protocol operates based on a schema that includes controls related to route, wire, and filter for the mixer input and mixer output.
