摘要： A method and system for communicating a conditional access signal through a network includes a source segment generating a first conditional access packet signal comprising a first header having a first destination identifier with a first format. The system also includes a first routing server associated with the source segment generating a second header with a second destination identifier having a second format different than the first format and replacing the first header with the second header. The system also includes a second routing server in communication with the first routing server through the network. The second routing server replaces the second header with a third header having a third destination identifier having the first format to form a third conditional access packet signal. A plurality of receiving devices receive the third conditional access packet signal.

摘要： A multi-ring IP multicast network is implemented with “N” instances of an Interior Gateway Protocol (IGP). Each IGP instance is autonomously configured on a different ring network to provide service separation between ring networks. Each IGP instance announces the one or more sources that are mapped on the associated ring network. Each source is announced in one and only one IGP instance so that the source is mapped on one and only one ring network. An “N+1” instance of the IGP is implemented on the core routers that are connected to receivers to merge and redistribute the “N” distinct instances of the IGP to the distribution and access routers between the core router and receiver. This effectively merges the N IGP instances at each node so that the multi-ring network appears as a virtual single-ring network with a single IGP instance allowing each of the receivers access to any source connected to the network.
摘要翻译：使用内部网关协议（IGP）的“N”个实例来实现多环IP组播网络。每个IGP实例在不同的环网上自主配置，以提供环网之间的业务分离。每个IGP实例都会公布映射在相关环网上的一个或多个源。每个源在一个且仅一个IGP实例中公布，以便源在一个且仅一个环网上映射。 IGP的“N + 1”实例在连接到接收器的核心路由器上实现，以将IGP的“N”个不同实例重新分配给核心路由器和接收器之间的分发和接入路由器。这有效地将每个节点上的N IGP实例合并，使得多环网络显示为具有单个IGP实例的虚拟单环网络，允许每个接收器访问连接到网络的任何源。
