Table 5
Pros and cons of standard architecture table summary.
| Pros | Cons |
| Best fit for less complex networks | Limited flexibility and service provisioning | Cost-effective | Issues with bandwidth on demands | Balances the speed of optical networks and the flexibility in SDNs | Difficulty in making intelligent decisions as the network becomes more complex | ā | Power consuming when the centralized network has lots of loads/burdens | ā | Not compatible with current ROADM devices (CDC ROADMs) |
