摘要： There is provided a method of forwarding a traffic flow in a communications network having at least one network node for which network traffic is selectively prevented from transiting the network node. The method includes the step of selecting a specified category of network traffic that is to be prevented from transiting the network node. The method also includes the step of determining a path within the network for forwarding the traffic flow, whereby the network node is excluded for transit in establishing the path where the traffic flow is identified with the specified category of network traffic.
摘要翻译：提供了一种在具有至少一个网络节点的通信网络中转发业务流的方法，网络业务被选择性地阻止其转发网络节点。该方法包括选择要被阻止的指定类别的网络流量转移网络节点的步骤。该方法还包括确定网络内用于转发业务流的路径的步骤，由此在建立以特定类别的网络业务识别业务流的路径的情况下排除网络节点进行传输。

摘要： The invention provides a system and method for identifying a pre-computed path for an incoming connection at a node in a policy-based routing network. The method comprises: examining requirements of the incoming connection; examining policies associated with routes available from the node; identifying at least one policy of the policies which meets the requirements of the incoming connection; and utilizing that one policy for the pre-computed path for the incoming connection.

摘要： A method and system for improving call routing in a PNNI network using crankback messaging. A destination logical group node (LGN) blocked crankback procedure is used by entry border nodes, in the event of a failed connection attempt, to instruct preceding routing capable nodes to route the connection over another link. If the entry border node is in the lowest level peer group a Succeeding End Blocked (SEB) crankback message is sent to the preceding routing-capable node. If the entry border node is not in the lowest level peer group, a destination LGN blocked crankback message is sent to the preceding routing-capable node wherein the message has special information to signal the routing node that the link into the destination LGN is blocked.
摘要翻译：一种改善PNNI网络呼叫路由的方法和系统，在连接尝试失败的情况下，入口边界节点使用目的地逻辑组节点（LGN）阻止曲柄程序来指示先前的路由能力节点将连接路由到另一个链路上。如果入口边界节点处于最低级对等体组，则将向后面的路由功能节点发送成功结束阻塞（SEB）曲柄消息。如果入口边界节点不在最低级别的对等组中，则将目的地LGN阻止的曲柄返回消息发送到先前的具有路由能力的节点，其中消息具有特殊信息以向路由节点通知到目的地LGN的链路被阻塞。
