Description: Link redundancy refers to the inclusion of additional links in a network to ensure reliability and availability. This approach is fundamental in modern network architecture, where service continuity is critical. By implementing link redundancy, multiple paths are created for data to flow between devices, minimizing the risk of interruptions due to hardware failures or connectivity issues. This technique not only enhances network resilience but also optimizes performance by allowing load balancing across available links. Link redundancy can be implemented through various technologies and protocols, such as Spanning Tree Protocol (STP) and Link Aggregation Control Protocol (LACP), which help manage and maintain the integrity of redundant connections. In various environments, link redundancy is essential to ensure that critical applications remain operational, even in the event of network infrastructure failures. Furthermore, in the context of software-defined networks (SDN) and network function virtualization (NFV), link redundancy becomes a key component for security orchestration and automated incident response, ensuring that networks are both flexible and robust.
