In today’s world of constant connectivity, network redundancy is an important aspect of network design. Networks go down from time to time due to various reasons such as hardware, software, or even natural disasters. To provide a reliable network, network redundancy is essential. Spanning Tree Protocol (STP) plays a vital role in network redundancy. In this article, we will discuss STP and its importance in network design.
Spanning Tree Protocol
Spanning Tree Protocol is a protocol that prevents bridging loops in a network. A bridging loop happens when there is more than one path between two destinations in a network. When a broadcast packet comes to a switch, the switch broadcasts the packet to all devices connected to it, including the device that sent the packet. If there is a bridging loop, the packet will be forwarded between the switches, creating a loop, causing the network to be congested. In this situation, there will be a lot of broadcast traffic and a single packet could go around the same loop multiple times, causing data loss, making the network ineffective.
STP acts by analyzing the configured network topology and blocking redundant paths. STP finds the root bridge that is used to control the direction of traffic in a network. A root bridge is the backbone of a network, and all traffic flows through it. STP then finds the best path from all devices to the root bridge and disables other paths. STP elects a root bridge and finds the best path from the root bridge to all other devices in the network. STP sets the best path for each device and then disables the other paths.
Benefits of STP
STP helps in preventing network loops in a network. STP is used to provide a reliable network by preventing broadcast storms that could cause network outages. STP provides network redundancy, which helps in avoiding a single point of failure in a network. STP also enables IT professionals to create a highly available network by designing multiple redundant paths.
Moreover, network administrators can use STP to manage and control traffic flow in their networks. STP can direct traffic over specific paths and choose alternate paths if there is a network outage. Advanced versions of STP allow IT professionals to create multiple VLANs, and they can control the forwarding of packets using access control lists. By using these features, IT professionals can create a secure and efficient network.
Conclusion
In conclusion, STP is a vital protocol for network redundancy. It prevents bridging loops in networks that could cause network outages, resulting in downtime for businesses. STP provides network redundancy, which is essential in network design. Network administrators can use STP to manage and control traffic flow in their networks. STP also allows IT professionals to create highly available and reliable networks. IT professionals must understand the importance of STP and its role in network redundancy to create an efficient and reliable network that meets the demands of their businesses.
