16 * This interface defines the methods for topology notifications provided by SAL
17 * toward the application. For example an application that wants to keep up to
18 * date with the updates coming from SAL it will register in the OSGi service
19 * registry. This interface (on a per-container base) and SAL will call it
20 * providing the update.

24 * Called to update on Edge in the topology graph

28 * Properties ( BandWidth and/or Latency etc) and update type.

37 * The edge which bandwidth usage is above the safety level
