Unlike other configuration managers on the market, NSO focuses not only on reading but WRITING deep fine-grained configurations to the network. NSO provides configuration management for both devices and network services. Any detailed parameter can be changed and NSO will generate the minimum configuration changes to the devices (not the entire config files).
NSO applies distributed transactions to all network changes. That is, if there is an error on any device when committing a change to the network, none of the other devices in that transaction will be changed. This includes non-transactional devices like CLI and SNMP. When NSO writes the configuration changes it is capable of generating any reverse operations to keep the network and NSO in a consistent state (these reverse operations are stored in rollback files).
