Comments and Suggestions for Authors

1.  How to calculate the recovery delay shown in Fig. 3? Which memory did the AHP and ANP method choose ? Which paramters are used in the calculation of the delay?

2. Which figure is mentioned in Line 342 ?

Reviewer 2 Report

Comments and Suggestions for Authors

This paper investigates how ANP help to select technology from other memory technologies including NAND, 3D XPoint et al, to be in conjunction with TCAM. Because this paper mentions some popular memory types, hence it would cause interest of readers how TCAM would cooperate with those tehcnologies. But this is a simulation paper, it is also very critical to convince people the effectiveness of the model you employed here.

1. Since you mentioned how ANP determined the rank of the memory types including NAND, MRAM, et al, how the ranking would be different for the examples you listed at the last, such as Abilene, RedIris and DFN?

2. Please clarify the scenarios where you prefer to use weighted supermatrix,  vs. Limit supermatrix.

Reviewer 3 Report

Comments and Suggestions for Authors

The authors provided a scheme to enhance TCAM capacity with other memory technologies and a mathematical decision-making model. Then, the effectiveness are further validated by using two kinds of switches. The novelty should be enhanced which looks like a research report not an academic paper. Specifically, there are some problems that need to be addressed as follow:

 

1 The key parameters of each memory technology should be provided as well as the main weakness. Table 1 and Table 2 should add more detailed information.

 

2 The author mentions different criteria for suitable memory technology and then applies them to the ANP method in Figure 2, but where do the specific calculation parameters of these criteria come from? Are there any specific schemes to quantify these criteria? In Table 3, the importance of memory feature is too rough without scientific assessment.

 

3 Provide specific results of combining with TCAM based these alternative memory with detailed information. Also, the English should further improved.

 

Comments on the Quality of English Language

Shoulde be further improved.
