Automatic resource & topology discovery makes OSN NEs completely plug and play. Compared with traditional SDH network, the automatic discovery of intelligent network makes the network more extendable and economical.

Provides E2E services and management through the legacy network and the ASON network by point&click, so as to reduce the steps of operation, make service provisioning faster.

Provides multiple SLAs by introducing restoration combined with protection, with different kinds of protection mechanisms (such as: " permanent 1+1 protection" ,"1+1/1:1 protection + restoration ", "share mesh restoration" , "dynamic/pre-calculating restoration") to meet different service demands.

Private lines can be ensured to be "always on line" with top-level protection mechanism. LCAS+VCAT together with GMPLS/ASON mechanism provide the Ethernet private lines guaranteed bandwidth.

Intelligent Timing Distribution (ITD) can automatically discover the clock topology to avoid the clock looping . Therefore, the configuration is much simpler than traditional way. For a normal-sized network, it just need to configure the primary reference clock source only. In addition, the survivability of the ITD is much higher since it has the ability to avoid the multipoint failure.
