What’s a Optical Switch? •  Monitor the optical power level in real time •  Switch to the other port automatically in about few milseconds if

the optical power is down •  It also can switch manually

How to use it in IXP ? •  Install the Optical switch between the IXP’s switch and the

customer router

Why we use it for?

• Continuously •  The customer can use IXP service continuously if primary

switch go down

• O&M cost reduction •  IXP don’t have to need the operator who change the cabling

in the case above

•  Easy-to-Maintain •  IXP is able to maintain the switches without stopping their

service

Confidential

Use case for xSP •  Carrier Diversity for site-to-site connection.

Time to switchover

• Optical Switch detect power loss

• Switch over to other port

• Physical Link Up at secondary switch

• Protocol Up at secondary switch The router should be configured “relevent” time. - carrier-delay / link debounce (Cisco) - hold timer (Juniper)
