Abstract: A switching device (e.g., router, bridge) provides time-based authorization of multicast services. When a message is received to request the delivery of a multicast service or a first message is sent to a multicast group, a subscription policy for the IP multicast subscription service is retrieved. This subscription policy includes one or more limitations which allow the IP multicast subscription service during some predefined time of day/week or duration but prevent the IP multicast subscription service during some predefined time of day/week or duration. The switching device is configured to enforce these time-based authorization of multicast services policies.

Abstract translation: 交换设备（例如，路由器，桥接器）提供多播服务的基于时间的授权。 当接收到请求传送多播服务的消息或者向多播组发送第一消息时，检索用于IP多播订阅服务的订阅策略。 该订阅策略包括在日/周或持续时间的某个预定时间内允许IP组播订阅服务的一个或多个限制，但是在日/周或持续时间的某个预定时间期间阻止IP组播订阅服务。 交换设备被配置为强制实施多播服务策略的这些基于时间的授权。

Abstract translation: 一种开关设备（例如，路由器，桥接器）提供的多播服务的基于时间的授权。 当接收到一个消息，以请求一个多播服务或第一消息的传送被发送到多播组，对IP多播的订阅服务的订阅策略检索。 此订阅策略包括一个或多个限制，允许在天/周或持续时间的某一预定时间的IP多播订阅服务，但防止在天/周或持续时间的某一预定时间的IP多播订阅服务。 切换装置被配置为执行多播服务的策略的这些基于时间的授权。
