What is the performance criteria in the selection of a route packet switched data network?

The performance criteria for selecting a route in a packet-switched data network include metrics such as latency, bandwidth, reliability, and throughput. Latency measures the time taken for data to travel from source to destination, while bandwidth indicates the maximum data transfer rate. Reliability assesses the network's ability to maintain consistent performance without failures, and throughput measures the actual data transfer rate achieved. Together, these criteria help ensure efficient and effective data communication across the network.
