http://en.wikipedia.org/wiki/Peering

“Peering is a voluntary interconnection of administratively separate Internet networks for the purpose of exchanging traffic between the customers of each network “

Also known as settlement-free peering

What is Peering?


http://en.wikipedia.org/wiki/Peering

Traditionally most Internet Exchanges are Layer2 exchanges

Allowing for bi-lateral peerings. Big Switch inter connecting all parties.

Examples:BCNET Transit Exchange (VANTX)Seattle Internet Exchange (SIX)Amsterdam Internet Exchange (AMS-IX )London Internet Exchange (LINX)

Total Seattle Traffic


SIX + Google Traffic.All time: 748Mb/s (95%), 924Mb/s (all time Max / Olympics)

Benefits for BCNET members


Significant Transit savings for VANTX membersAllows for extra (additional) traffic!

Most Transit links are cappedIX is ‘unlimited’Better user experience

(these number include PIX)

Transit 95% (IN)

IX 95% (IN)

UBC RESNET 52% 48%

SFU 55% 45%

UBC Campus 55% 45%

UVIC 65% 35%

Benefits for BCNET


• Significantly more Bandwidth for ~10% of Transit price• Shorter Paths• Fast access to large content providers• Increased redundancyPath to SIX peers is not shaped, i.e. better throughput

ConcernsSIX does not have SLA, ‘get what you pay for’Non redundant link to Seattle

Investigate extending SIX service to other Transit locations.Successful Trial done with UVIC

Explore possibilities of contracting Transit services in Seattle.

Investigate possibilities for redundant paths

Future plans
