Abstract

The huge size of network and diversified business characteristics make network traffic difficult to predict and manage. Network measurement is an effective way which can ensure QoS (Quality of Service) and network optimization. However, due to the differences in the implementation rules of equipment (such as switches, routers etc), it is difficult to achieve accurate and timely network measurement in traditional networks. Recently emerging software defined network (SDN) separates the network control plane from the data forwarding plane and manages the whole network through the centralized controller platform which improves the efficiency of the network management. The new network model adopting unified south bound(SB) interface protocols (openflow is the commonly SB protocols) to access network equipment which shields the different implementation details of the underlying network equipment. The SDN solves the problems that the heterogeneous devices statistical information which is difficult to obtain and greatly simplifies the complexity of network measurement. On the basis of extensive research, this paper introduces the network measurement methods commonly used in Sandwich including sampling method, link latency measurement and link packet loss measurement method. We believe that the network measurement technology in SDN will greatly optimize the performance and accuracy of network measurement and can provide better guarantee for network quality.
