  • Causes of network congestion in core switches

    Causes of network congestion in core switches

    Congestion is often caused by bandwidth limits, overloaded devices, inefficient routing, broadcast storms, misconfigured applications, or sudden traffic spikes. Network congestion occurs when the request for network resources overcomes the available capacity, managing to slower data transmission, packet loss, and delays. This situation is commonly observed in computer networks, such as internet, where multiple devices and applications resist for limited. Network switches play a pivotal role in managing and directing traffic within a network, making them essential components of modern connectivity.
