Abstract:This paper proposed a multi-layer tracer deployment schemewith the K-diameter algorithm. In the scheme, chosen a larger k-could to value diameter tracer deployment at the first layer. As a result, needed less cost to deploy comparatively few tracers for the sake of conducting the pivotal tracing. The second diameter at the second layer was to deploy tracers in the area of diameter. Could confirmed the source of attack thus by tracing again the attacks which couldn’t be traced at the first layer node. The scheme could trace accurately with lower costs of network transformation and network performance. The theoretical analyses and the simulations verified the scheme is correct and valid. ......
