Title: “A Reinforcement Learning Method for Dynamic Topology Control in Data Center Networks”

Abstract:

This paper proposes a reinforcement learning method for dynamic topology control in data center networks. Since data center networks are usually distributed, large and complex, how to establish a dynamic and stable topology for data center networks has become a research hotspot. The proposed method integrates the reinforcement learning algorithm and the distributed topology control framework, and applies it to data center networks. The simulation results show that the proposed method has higher convergence rate and stability compared with traditional topology control algorithms, and it is suitable for the dynamic and complex topology control in data center networks.

Introduction:

Dynamic topology control is an essential issue in data center networks, and it is closely related to the network performance and reliability. Traditional topology control algorithms, such as the diffusion algorithm and the local search algorithm, suffer from poor scalability and stability. Therefore, this paper proposes a reinforcement learning method for dynamic topology control in data center networks. The proposed method combines the reinforcement learning algorithm and the distributed topology control framework, and applies it to data center networks. The remainder of this paper is organized as follows: Section 2 introduces the related work, Section 3 presents the proposed method, Section 4 describes the simulation results, and Section 5 concludes the paper.

Related Work:

Topology control is a fundamental issue in wireless networks, and it has been widely studied in recent years. However, topology control in data center networks is much more complex than that in traditional wireless networks, due to the high degree of heterogeneity, mobility and uncertainty. Traditional topology control algorithms, such as the diffusion algorithm, the minimum spanning tree algorithm and the local search algorithm, have been widely used in data center networks. However, these algorithms have poor scalability, slow convergence and limited adaptivity. Therefore, it is necessary to develop new topology control algorithms for data center networks.

Proposed Method:

The proposed method is a reinforcement learning-based topology control algorithm for data center networks. The objective of the algorithm is to obtain a stable and flexible topology configuration for data center networks. The algorithm consists of three main components: (1) Q-learning model, (2) topology control mechanism, and (3) learning algorithm. In the Q-learning model, the state space is defined as the set of all possible network topologies, the action space is defined as the set of all possible configurations of network parameters, and the reward function is defined as the network performance. In the topology control mechanism, each node can adjust its transmission power and channel allocation dynamically according to the network state. In the learning algorithm, the Q-values are updated using the Bellman equation, and the best action is selected based on the Q-values.

Simulation Results:

The simulation results show that the proposed method has higher convergence rate and stability compared with traditional topology control algorithms, such as the diffusion algorithm and the minimum spanning tree algorithm. In addition, the proposed method has better adaptivity to the network dynamics, and it can achieve good performance even when the network topology changes abruptly. The experiments also show that the proposed method can reduce the communication delay and improve the network throughput significantly in different scenarios, such as data center networks with different topologies, different workloads, and different failure patterns.

Conclusion:

This paper proposes a reinforcement learning method for dynamic topology control in data center networks. The proposed method integrates the reinforcement learning algorithm and the distributed topology control framework, and applies it to data center networks. The simulation results show that the proposed method has higher convergence rate and stability compared with traditional topology control algorithms, and it is suitable for the dynamic and complex topology control in data center networks. Future work will focus on further improving the performance of the proposed method and extending it to other network scenarios.
