Description: A redundant network interface is a critical component in modern network architecture, designed to ensure continuous and reliable connectivity in environments where availability is essential. This interface allows for the creation of multiple communication paths between devices, meaning that if one path fails, another can take its place without interrupting service. Key features of a redundant network interface include the ability to detect failures in real-time, automatic switching to alternative paths, and integration with load balancing technologies. Its relevance lies in the growing dependence of businesses on constant connectivity, especially in the context of cloud networks and content delivery networks (CDNs), where service disruption can result in significant losses. In summary, a redundant network interface not only enhances the resilience of network infrastructure but also optimizes performance by efficiently distributing traffic load.
