Using contour coefficient to judge the number of K-means clustering
1, kmeans cluster processing data must be numeric numeric, and must be matrxi or data frame
2, profile coefficient can use FPC package
3, clustering effect does not have a special evaluation criteria, the number of clustering can be judged by this.
4, the number of clustering of other methods can also adopt hierarchical clustering method, from the graphic results of the classification of categories Hclust (see last)

The IPv6 Neighbor Discovery Protocol Neighbor Discovery replaces the ARP protocol in IPv4 to obtain the Mac address of machines in the LAN. This is a prerequisite for communication between hosts in the LAN. The Neighbor Discovery Protocol consists of two formats: the neighbor request NSNeighbor Solicitation) and the neighbor request NANeighbor Advertisement ).
How IPv6 Neighbor Discovery works:
Before communication between two hosts A and B in the LAN, A must first obtain the MAC address of B. T
