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

Scoundary Switch

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

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)
