Routing Metrics This lesson discusses routing metrics and the qualities used to determine the best path: - Hop count: how many other routers does a signal need to pass? - Maximum transmission Unit (MTU): The maximum size of a single packet we can send - Casts: reliability - Latency: The amount of delay we have on a link. Routers use different protocols to determine the best path: - Link state: This is a cost-based protocol. An example of a link state is Open Shortest Path First (OSPF) protocol - Distance Vector: Just based on the number of 'hops' - Hybrid: A mixture of distance vector and link state, it uses 'hop' count and cost
