Topology.getLink介绍

[英]A Network Link connects a by Local (Source) node anda Remote (Destination) Network Nodes via a set of thenodes' termination points.As it is possible to have several links between the samesource and destination nodes, and as a link could potentiallybe re-homed between termination points, to ensure that wewould always know to distinguish between links, every linkis identified by a dedicated link identifier.Note that a link models a point-to-point link, not a multipointlink.Layering dependencies on links in underlay topologies arenot represented as the layering information of nodes and oftermination points is sufficient.
[中]网络链路通过一组节点的终止点连接本地（源）节点和远程（目标）网络节点。由于同一资源和目标节点之间可能有多条链路，并且一条链路可能会在终止点之间重新建立，为了确保我们始终知道如何区分链路，每个链路都由一个专用的链路标识符标识。请注意，链路建模的是点到点链路，而不是多点链路。在参考底图拓扑中，对链接的分层依赖性不能表示为节点和端点的分层信息。
