  8. 8. Confidential 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 Optical Power Optical Switch Optical Power Optical Switch Monitor the Optical power
  9. 9. Confidential How to use it in IXP ? •  Install the Optical switch between the IXP’s switch and the customer router Optical Switch Customer IXP Primary Switch Scoundary Switch
  10. 10. Confidential 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
  11. 11. Confidential Use case for xSP •  Carrier Diversity for site-to-site connection. Optical Switch Site A Site B Optical Switch Carrier A Carrier B
  12. 12. Confidential 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) > 10ms A few ms A few ms
