摘要： A method is provided in one example and includes receiving a current bandwidth characteristic for a link, where the current bandwidth characteristic is determined under fading conditions associated with signal propagation on the link. The method can also include calculating a new cost for the link that is different from a nominal cost associated with a nominal bandwidth of the link without the fading conditions. The method could also include routing at least a portion of a plurality of flows that are to traverse the link away from the link based, at least in part, on the new cost. Another example method includes receiving the current bandwidth characteristic for the link, comparing the current bandwidth characteristic with a preconfigured low watermark corresponding to a class-specific MTR topology associated with a class of traffic traversing the link, and removing the link from the MTR topology based on the current bandwidth characteristic.

摘要翻译：在一个示例中提供了一种方法，并且包括接收用于链路的当前带宽特性，其中在与链路上的信号传播相关联的衰落条件下确定当前带宽特性。该方法还可以包括计算不同于没有衰落条件的与链路的标称带宽相关联的名义成本的链路的新成本。该方法还可以包括至少部分地基于新成本路由将要从链路横越链路的多个流的至少一部分路由。另一示例性方法包括：接收当前带宽特性，将当前带宽特性与对应于与通过链路的一类流量相关联的类特定MTR拓扑相对应的预配置低水印，以及从基于MTR拓扑的链路中移除链路关于当前的带宽特性。
