    Abstract: A content distribution network includes a first server in communication with an anycast server that provides content via a unicast signal, and with a multicast server that provides the content via a multicast signal. The first server is configured to receive a list of source addresses associated with the content, and to provide a metadata file including an anycast Internet protocol address of the anycast server from the list of source addresses as an Internet protocol address of the content in response to a first request for the content. When the number of client devices requesting the content exceeds a first threshold, the first server receives an updated list of sources including a multicast Internet protocol address of a multicast server, and provides the multicast Internet protocol address of the multicast server as the Internet protocol address of the content in the metadata file.

    Abstract translation: 内容分发网络包括与通过单播信号提供内容的任播服务器通信的第一服务器，以及经由多播信号提供内容的多播服务器。 第一服务器被配置为接收与内容相关联的源地址的列表，并且从源地址列表中提供包括任播服务器的任播网络协议地址的元数据文件作为响应于内容的内容的因特网协议地址 第一个请求的内容。 当请求内容的客户端设备的数量超过第一阈值时，第一服务器接收到包括多播服务器的组播互联网协议地址的源的更新列表，并且将组播服务器的组播互联网协议地址提供为因特网协议地址 的元数据文件中的内容。

    Abstract: A content distribution network includes first and second controllers, and multicast enabled routers. The first controller is configured to select a multicast channel for distributing content, to determine that the content has a geographic restriction associated with a restricted area in the content distribution network, to link an exclusion policy for the content to the multicast channel while the multicast channel provides the content, and to deny a request for the content from a client system within the restricted area based on the exclusion policy. The second controller is configured to distribute the exclusion policy to the multicast enabled routers including a first router configured to store the exclusion policy, and to ignore a multicast join message from the client system within the restricted area based on the exclusion policy.

    Abstract translation: 内容分发网络包括第一和第二控制器以及启用多播的路由器。 所述第一控制器被配置为选择用于分发内容的多播信道，以确定所述内容具有与所述内容分发网络中的受限区域相关联的地理限制，以将所述内容的排除策略链接到所述多播信道，而所述多播信道 提供内容，并且基于排除策略来拒绝来自限制区域内的客户端系统的内容的请求。 第二控制器被配置为将排除策略分发到启用多播的路由器，包括配置为存储排除策略的第一路由器，并且基于排除策略忽略来自限制区域内的客户端系统的多播加入消息。

    Abstract: Concepts and technologies are disclosed herein for providing and using a software defined network controller. A software defined network controller can be provided by a computing system that includes a processor. A service model that represents a service can be obtained. A network model that represents network resources that support the service can be obtained. Resources that support the service can be determined. Templates can be accessed to identify templates that relate to the resources. The templates identified can be assembled to obtain a template-based representation of the service. The template-based representation can be executed to determine if the service is ready for deployment.
