The “Overall rerouted prefixes by provider” graph provides the number of prefixes that were rerouted from and to each of the providers. In the example below, the traffic exchange between the providers is balanced. However, if the difference between the outgoing and incoming traffic is significant, then the quality of that provider’s network should be questioned.
“In” represents prefixes rerouted to a provider, “Out” represents prefixes rerouted from a provider. The “Excess In/Out” values represent the difference between the number of prefixes rerouted to a particular provider and the number of prefixes rerouted from this provider.
“In” represents prefixes rerouted to a provider, “Out” represents prefixes rerouted from a provider. The “Excess In/Out” values represent the difference between the number of prefixes rerouted to a particular provider and the number of prefixes rerouted from this provider.
