ASON Increases 10 Folds Network Reliability
| Why do we need optical protection ?Simpler and faster than IP restoration, avoids the number of data links failure and routing shaking, when optical cable is broken |
|
Why do we need ASON protection ?Reliability decreased by 10 folds, when distance more than 600km Automated restoration against Multi failure |
Transport network carry heavy traffic of the numerous end users, especially in backbone, ASON is more effective mean to increase network reliability against multi failures.
ASON Is More Cost-effective
Because Its Restoration Can Share the Spare Route
Tradition 4 active channels + 4 spare channels( 1+1 ) |
ASON 4 active channels + 1 spare channels( 1:N ) |
Case Study :There’s 35 nodes for some provider’s WDM backbone network. It needs 85λ for traditional solution, and 67λ after ASON used. That is, 21% of resource saved.
Smart RWA
make optical layer restoration more reliable
RWA = Rerouting Wavelength Assignment
| Multi-constraintimpairment-awareRWA algorithm | Wavelength tunable rerouting |
ASON/GMPLS control plane will consider photonic parameter comprehensively to avoid unavailable photonic layer rerouting and choose regenerator automatically when necessary.
Also, allow wavelength tunable when rerouting to solve wavelength collision.
Greatly improve optical layer restoration reliability.
