Differences between an ASON network and a common SDH network
Differences between an ASON network and a common SDH network: In an ASON network, services are classified into several protection levels including diamond, gold, silver, copper and iron. The protection level can be enhanced and the service rerouting function is added in an ASON network. As a result, the actual bandwidth utilization of an ASON network is higher than 50%. A common network does not have the rerouting function.
