Abstract: Research on the relationships between metrics of the Internet topology values much for the research on modeling the Internet topology.The dK-series analysis is an efficient technique to analyse properties of the Internet topology，so it is an efficient tool for researching the relationships between metrics of the Internet topology.In this paper，the relationships between dK-series and some important topology metrics are investigated，which can be used to reduce the complexity of comparing two topology graphs.The research result can help the researchers of modeling the Internet topology to improve and validate their models.

Key words: Internet, network topology, network metrics, dK series
