A Link Status-Based Multipath Scheduling Scheme on Network Nodes

Round 1

Reviewer 1 Report

The manuscript shows a novel approach about: Link Status Based Multipath Scheduling Scheme on Network Nodes. The use of NS3 is very interressing and add value to this article.

In general, the structure is nice, and content of the paper is quite interesting to be considered for publication.

Some items that should be improved are:

-show some LSADB fo routers

-show some routing table

Future work most be using iBGP, in figure 6, can authors write about

Reviewer 2 Report

The authors propose a novel scheduling algorithm for network nodes utilizing multiple paths. This algorithm reimagines the conventional next-hop node as a group of potential next-hop nodes, considering global and local routing strategies. It periodically adjusts the traffic distribution for each next-hop node within the group based on the corresponding link status, aiming to reduce link congestion and improve forwarding ability.

In my opinion, the work is good; however, there are some comments to improve the scientific depth of the paper:

1. The authors should provide a clear explanation of how the network nodes create sets of next-hop scheduling alternatives and how the traffic distribution is modified based on the link statuses.

2. The authors should provide a clear description of the algorithmic logic and decision-making process.

3: The authors should explain how the feedback is relayed from the affected node to upstream nodes and how the responsibility for scheduling is transferred.

4: The authors should give some discussion of the specific protocols used for communication between network nodes and the coordination of scheduling decisions.

5: The authors should give a detailed explanation of how the control plane and data plane are designed and how they interact with each other to enable multipath scheduling and feedback.

6: The authors should clarify how the proposed scheme can be integrated into different network environments and whether any modifications or adaptations are required for seamless interoperability.

Reviewer 3 Report

A good paper presenting a multipath scheduling approach for network nodes, capitalizing on the advanced features of these modern nodes. Simulations results presented by the authors show that this approach effectively leverages network path variety, also improves bandwidth usage and throughput, and minimizes average data transmission time. Perhaps instead of the program code a block diagram could have been more suitable.
