Description: Routing overhead refers to the additional data required for routing information in a network that does not carry user data. This phenomenon is crucial in the context of computer networks, where devices must exchange information on how to direct data packets through the network. Routing overhead includes information such as source and destination addresses, routing metrics, and other parameters that help routers make informed decisions about the best path to send data. This overhead can impact the overall performance of the network as it consumes bandwidth and processing resources. As networks grow in size and complexity, managing this overhead becomes increasingly critical, as excessive routing information can lead to congestion and increased latency. Therefore, it is essential to optimize the amount of routing information exchanged to maintain network efficiency and performance.
