Abstract: Methods, systems and computer readable media for quality of service aware hybrid multicast networks are described. A method can include receiving a request for content from a first receiver and initiating a quality of service aware hybrid tree construction by sending a multicast service level specification message to a first overlay tree manager. The method can also include dividing the tree at the overlay tree manager and communicating with other overlay tree managers in the network. The method can further include computing, at each overlay tree manager, a shortest path tree using a constrained algorithm and sending, from each overlay tree manager, a message to each IP manager in the network requesting that the IP managers construct an IP multicast tree and install the tree on one or more corresponding routers. The method can also include enforcing multicast routes and quality of service on the one or more routers.

Abstract translation: 描述了用于服务质量感知混合组播网络的方法，系统和计算机可读介质。 一种方法可以包括从第一接收器接收对内容的请求，并通过向第一覆盖树管理器发送多播服务级别规范消息来发起服务质量感知混合树构建。 该方法还可以包括在覆盖树管理器处划分树并与网络中的其他覆盖树管理器进行通信。 该方法还可以包括在每个覆盖树管理器处使用约束算法来计算最短路径树，并且从每个覆盖树管理器向网络中的每个IP管理器发送一个消息，请求IP管理器构造一个IP组播树， 将树安装在一个或多个相应的路由器上。 该方法还可以包括在一个或多个路由器上实施组播路由和服务质量。
