Enhancement in Loop Prevention Protocols: Dynamic Per-VLAN Multi-shortest Path Bridging (DV-MPB)

Abstract

Loops in a network pose significant challenges in modern communication systems, leading to congestion, performance degradation, and potential system failures. Additionally, loops can cause broadcast storms, impacting the network performance. While traditional loop prevention mechanisms like the Spanning Tree Protocol (STP) have been effective, the evolving complexity of network environments demands more efficient solutions. This paper provides a comprehensive review of loop prevention protocols, including STP, Rapid Spanning Tree Protocol (RSTP), Multiple Spanning Tree Protocol (MSTP), Shortest Path Bridging (SPB), and Per-VLAN Spanning Tree (PVST). Further, this paper introduces Dynamic VLAN - Multi-Shortest Path Bridging (DV-MPB) as a potential solution to enhance loop prevention efficiency. DV-MPB combines the strengths of SPB and PVST to achieve dynamic traffic optimization and reduce convergence time in loop prevention protocols. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.
