Optical Network
• Focus on permanent circuits– Connection to the AARNet3 backbone– Inter campus links
• NOC out sourced to Cisco/SOUL• Will interconnect to SXTransPORT
– Providing light paths from Los Angeles to anywhere on the optical network
– Issues to be resolved with configuration management and control

Peering in AARNet
• AARNet has > 200 peers• 66% of AARNet’s international
commodity traffic is received via peering
• 50% of AARNet’s domestic commodity traffic is received via peering
• Currently only doing IP peering– Might do VoIP eventually

Lessons Learned• Many cables hit by single event so vendor
diversity didn’t help• Sometimes focus on RTT and cost is bad• Need geographic diversity• Working as a “club” can improve diversity if
someone buys the “strange” or expensive path
• But Internet soon discovered the alternative paths– What you think is a backup path may not be the
one used in practice– China to Japan via Chicago!
