Analysis of IP Flows Rate in Large-scale Networks
大规模网络中IP流流速分析

As one of most important components of Intemet traffic modeling,the IP flow rate can be used to describe the load distribution of different applications in the network.And it is essential condition for IP flow model that some key factors could be found which influenced the flow rate heavily.Firstly,this paper modeling the IP flow rate based on protocol analysis for the three main components:TCP flows,UDP flows and ICMP flows.From the analysis of pa- rameters of those models,the flows rate are found out to be determined by some influence factors.And then,those TRACEs which come from the networks with different time,different areas and different payloads are chosen as study objects.IP flow rate of the different protocol IP flows in these traces are analyzed using statistical method.The influ- ence factors are verified their efficiency for the IP flows rate with different length in the actual networks,and the relia- bility of the IP flows rate influence factors which are introduced by this paper is also verified.
