An Effective Method of Monitoring the Large-Scale Traffic Pattern Based on RMT and PCA

Figure 2

The pattern of P2P traffic, calculated by complete information. For each peer in the group A1, D2, J5, K2, and K3, rate = 25, starting time = $125\mathrm{\hspace{0.17em}\hspace{0.17em}}(X=(125*2\text{–}200)*0.1=5)$. Then peers of D2 leave at $t=160$ and peers of H2 join in at $t=200\mathrm{\hspace{0.17em}\hspace{0.17em}}(X=(200*2\text{–}200)*0.1=20)$ with rate = 35.
