Load Balancing Heterogeneous Multipath Authentication Routing Selection for Endogenous Software-Defined Networks

The rise of software-defined networking (SDN) has greatly enhanced the flexibility and programmability of networks, but it has also brought new security challenges while achieving more efficient multipath, more flexible load balancing, and more secure authentication. To address this problem, we propose an innovative solution: the load-balanced heterogeneous multipath authenticated routing selection (LBHMARS) framework. This framework implements load balancing of multipath routing, as well as authentication and location of compromised switches in SDN networks, while ensuring the security of traffic entering the system. LBHMARS establishes a secure and efficient routing mechanism in SDN using the IPv6 protocol. We combine strong encryption and signature schemes with a novel path load balancing algorithm to ensure traffic balance and data integrity among multiple network paths. Finally, we introduce a mechanism to locate and isolate malicious switches, further enhancing network security. Compared with existing solutions, our extensive simulations show that LBHMARS has superior performance in mitigating attacks and maintaining high network throughput. In addition, LBHMARS also performs well in terms of latency and low packet loss.
