## Response to Reviewer 1
### Point 1:
The method part shall be presented formally. Currently, each sub-method of the proposed mechanism is described in the form of rough steps. This reviewer suggests that they shall be written in formal mathematical algorithm format and more complete details in each step should be illustrated. Then, it would be more like a rigorous journal article.

### Response 1:
As you mentioned, our manuscript was lacking in details about the Spectral Residual method and the method for detecting anomalous increase in Packet-In messages.
Therefore, We have added a more detailed description of the SR method using mathematical formulas (p.6 LL111 - 120), and algorithmic form about the anomaly increase detection method (p.7 Algorithm 1).

### Point 2:
In the previous version of this paper, a K-NN detection method is used. As an extension paper, a complete comparison shall be provided in the evaluation part. So, both performance results of the polling method and the previous method with K-NN detection shall be provided in the Evaluation Section and be compared with the proposed method.

### Response 2:
Our manuscript lacked a comparison in terms of evaluation with the APNOMS2020 submission. Therefore, we have conducted new experiments and added the results as Experiments 2 and 3 (p.9 - 11).
In Experiment 2 of Chapter 4.4 (p.9 LL197 - 208, Figure 12), we compared the CPU overhead of the Spectral Residual (SR) used in this paper with that of the kNN used in APNOMS2020 submission.
Also, in Chapter 4.5 (p.11 LL209 - p.12 LL224, Table 6), we evaluated the detection performance of SR and kNN.

### Point 3:
The reference information is incomplete. The authors shall thoroughly check this part and fix the problem. For example, links are missing in references [1][5][15][16][17] and the source conference information is not provided for references [4][9][10][11][12][13].

### Response 3:
As you mentioned, there were problems with the reference.
Therefore, we have checked for references and included links and conference information.
Thank you very much for your careful review.


## Response to Reviewer 2
### Point 1:
There are no references to chapter 2.3. Please add a reference.

### Response 1:
As you mentioned, the references were insufficient. Therefore, in Chapter 2.3 (p.3 LL59 - LL77), we have added references to previous studies and a sentence about the study we conducted when we submitted APNOMS2020.

### Point 2:
There is no performance comparison with previous studies in Chapter 4. Analysis is needed to evaluate the performance of the proposed method and the existing methods.

### Response 2:
We have added a comparison evaluation with the method we submitted in APNOMS2020.
We have conducted new experiments and added the results as Experiments 2 and 3 (p.9-11).
In Experiment 2 of Chapter 4.4 (p.9 LL197 - 208, Figure 12), we compared the CPU overhead of the Spectral Residual (SR) used in this paper with that of the kNN used in APNOMS2020 submission.
Also, in Chapter 4.5 (p.11 LL209 - p.12 LL224, Table 6), we evaluated the detection performance of SR and kNN.


## Response to Reviewer 3
### Point 1:
I think it would be helpful to briefly describe how the newly proposed method differentiates from the prior study [11].

### Response 1:
As you mentioned, There was a lack of description of the differences with our previous studies [11].
Therefore, we have added the issues from our previous research in the related research in Chapter 2.3 (p.3 LL69 - LL77).


### Point 2:
I think it would be interesting if the authors describe in details the followings:
(I) The four steps of the used Spectral Residual method.
(II) The used procedure to detect anomalous increases in packet-in messages.

### Response 2:
(I) In chapter 3.3 (p.6 LL111 - 120), we have added a more detailed description of Spectral Residual using mathematical formulas instead of abstract itemizations.
(II) Similarly, the method for detecting an increase in the number of Packet-In messages in Chapter 3.4 has been described in more detail in the form of an algorithm (p.7 Algorithm 1).

Comments:
In general, the paper is well written and well organized.

I think it would be helpful to briefly describe how the newly proposed method differentiates from the prior study [11].

I found the evaluations given in Section 4 to be thorough and interesting.

I think it would be interesting if the authors describe in details the followings:
(I) The four steps of the used Spectral Residual method.
(II) The used procedure to detect anomalous increases in packet-in messages.
