Abstract: A method for controlling transit of routing messages in a network comprising multiple autonomous systems (AS) is disclosed. The method includes receiving, at a first AS, a routing message of an inter-AS routing protocol and identifying that the routing message comprises transit domain control (TDC) information specifying one or more autonomous systems to which the routing message may be propagated and/or one or more autonomous systems to which the routing message may not be propagated. The method further includes propagating the routing message from the first AS to a second AS in accordance with the TDC information.

Abstract translation: 公开了一种用于控制包括多个自治系统（AS）的网络中的路由消息的传送的方法。 该方法包括在第一AS处接收跨AS路由协议的路由消息，并且识别该路由消息包括指定可以传播路由消息的一个或多个自治系统的传输域控制（TDC）信息和/ 或路由消息可能不被传播到的一个或多个自治系统。 该方法还包括根据TDC信息将路由消息从第一AS传播到第二AS。
