Cyfrifiadureg Lefel A2 A2 Level Computer Science 02 UNIT 4: Topic Data Transmission Lowest Cost Topic 02: Data Transmission What the Specification Says Topic 02: Data Transmission Metrics When deciding how to route data packets around a network, several factors need to be considered when determining the desired path form source to destination. These factors are known as metrics Metrics are the network variables used in deciding what path is preferred. For some routing protocols these metrics are static and may not be changed. For other routing protocols these values may be assigned by a network administrator. Topic 02: Data Transmission Metrics The most common metric values are Hop Bandwidth Delay Reliability Load Cost Topic 02: Data Transmission Metrics Topic 02: Data Transmission Metrics Topic 02: Data Transmission Metrics Topic 02: Data Transmission Past Paper Questions When transmitting data packets over a network, many factors known as metrics can be considered to determine the “best” path (a) Other than bandwidth and cost, state and describe three other metrics that could be considered when determining a route over a network.
