We applied Network Environ Analysis NEAA) to calculate resource homogenization for these models, where homogenization is defined as the ratio of the coefficient of variation of the direct flow intensity matrix (CV(G)) to the covariance of the integral flow intensity matrix (CV(N)).
The relationship between the probabilities is used to calculate resource utilisation from the number of ADEs requiring hospitalisation (ie. 4 times as many patients require only a physician visit compared to those requiring hospitalisation, the calculated factors are shown in Table 1).
The calculated resources load is then compared with the actual resources load.
The calculated resources load is compared with the actual resources load to determine if the calculated resources load is within a small range of the actual resources load (line 5).
On the other hand, the hypervisor revokes resources from the VM whose calculated resources load and actual resources load do not match (line 6-7).
In other words, the larger the difference between the calculated resources load and current resources load is, the more resources should be revoked from the VM.
If the calculated resources load is not within a certain range of the actual resources load, the belief that the VM has been compromised increases.
If the calculated resources load is within a short distance of the actual load, the algorithm identifies the resources load as normal (line 16-17).
If the calculated resources load is not within a short range of the actual resources load, there will be a high probability that the VM has been compromised.
However, we suggest that the amount be proportional to the magnitude of the difference between the calculated resources load and the current resources load.
