Anycasting A B F C E G D Anycast group member Links are bi-directional But algorithm imposes logical directions on them Maintain an directed acyclic graph (DAG) for each anycast group, with each group member being a sink Link between two sinks is not directed 248
DAG for Anycasting Since links between anycast group members are not given a direction, the graph is not exactly a “directed” acyclic graph So use of the term DAG here is imprecise Ignoring links between anycast group members, rest of the graph is a DAG 249
