Tree construction is a commonly used approach in solving the multicast routing problem . one advantage of multicast tree is that data are distributed to different multicasting destinations along the branches in parallel , which reduces the delay . the other is that message need only be replicated at forking nodes , which minimizes the data replication , spares the network bandwidth , reduces the network load and lessens the congestion 實現組播的一般方式是建立組播樹,組播樹的優點在于:首先,信息以并行方式沿著樹枝發送到不同的組播終點,從而降低了信息傳遞的時延;其次,信息的復制只在樹的分支處進行,因此網絡中需要傳送的復制信息量最少,能夠節約網絡帶寬資源,降低網絡負載,減少擁塞。
