Types of Spanning Tree Algorithms
Below are the types of spanning tree algorithms:
- Spanning Tree Protocol (STP): The original IEEE 802.1D standard that defines the basic operations of the spanning tree algorithm. It uses the original STP algorithm to calculate the loop-free topology.
- Rapid Spanning Tree Protocol (RSTP): An enhancement to STP defined in IEEE 802.1w. RSTP significantly reduces the convergence time compared to STP by introducing faster port transitions and additional port roles (e.g., alternate and backup ports).
- Multiple Spanning Tree Protocol (MSTP): Defined in IEEE 802.1s, MSTP allows for the creation of multiple spanning tree instances within a single bridged network. This allows network administrators to map VLANs to specific spanning tree instances, providing more efficient use of network resources.
- Per-VLAN Spanning Tree (PVST) / Per-VLAN Spanning Tree Plus (PVST+): Proprietary extensions of STP used in Cisco’s networking devices. PVST/PVST+ allows for the creation of a separate spanning tree instance for each VLAN in the network, providing greater flexibility and control over VLAN-based traffic.
Spanning Tree Protocol (STP) in Distributed Systems
In distributed systems, the Spanning Tree Protocol (STP) serves as a foundational mechanism for ensuring the stability and efficiency of network communication. At its core, STP is designed to prevent loops in the network topology, a scenario where data packets circulate endlessly between network nodes, causing congestion, packet loss, and potential network outages.
