Please note that in this file
* the network is represented as a directed graph.
* this network is an explicit decomposed network after graph decomposition.
* each node in the network has an ID number.
* ignore all isolated nodes (i.e. those without any link coming in and going out). The isolated nodes are previous merging nodes. They are decomposed after graph decomposition.    
* each number below represents a certain node in the network.
* each link is represented by a node pair (X,Y), where the direction is from node X to node Y.
* each link is associated three bandwidth attributes: the occupied bandwidth (B_occu), the maximum bandwidth (B_max = 100 Mbps), and the bandwidth for supporting NCM (B_s_T = 40 Mbps)
