This paper introduces the function of ATM switchingnet, test method of its fundamental parameter,and builds test environment of ATM switching net By means of this test environment,debugging hard circuit of 8×8 ATM switching net,and testing its fundamental function and electrical parameter,the result is satisfactory This paper plays an important role in practicality of ATM technolog

Compared with original algorithms,it is found that the proposed algorithm deals with the real-time path searching problem in large traffic network quickly and effectively with a small computer memory.

Anomaly detection of large scale network based on data streams;

Under the situation of current IDSs have no good performance to meet the large scale network s need.

Based on the discussions, the empirical model of IP flows distribution for large-scale networks is proposed based on the characteristics analysis, whose precision is better than Pareto model, and the complexity is less than double Pareto model.

Based on the former research on IP flows arrival distribution, this paper analyzed the interarrival time distribution and the autocorrelation of IP flows coming from different large-scale networks.
