    Multicasting is the most widely-used communication pattern in computer networks. 
How to determine an efficient multicast routing is one of  fundamental issues 
in multicast communication, and tree construction is a commonly-used approach 
in solving multicast routing problem. Multicast routing algorithms are used to 
construct good performance multicast trees which satisfy Quality of Service(QoS) 
requirement. Shortest Path Tree(SPT) is one of the most widely-used multicast tree type. 
There are maybe more than one shortest paths between two nodes in large-scale network, 
so the corresponding SPTs are not unique and costs of which are different.
