How to Prepare for a
Peering Partner Business

• Open peering policy - will peer with everyone and everywhere possible
• Selective peering policy - will generally peer, but there are a set of requirements that define how
mutual benefit can be gained from peering
• Restrictive peering policy - will peer, but not seeking new peers and will generally decline any
requests
Peering policy basics

• Ratio - the network requires a certain balance between the sent and received traffic from the
potential peer
• Volume - the network requires a certain volume to justify the increased workload involved in
setting up and maintaining connections
• Locations - the network requires a certain geographic overlap between the networks so they can
hand off traffic most efficiently and save bandwidth within their own network
• Customers of an existing peer - if your network is a customer of an existing peer to your peering
prospect, your traffic is already on a free connection for them and your traffic might be needed in a
potential ratio-relationship between your peering prospect and your provider

network?

Quality - Synthetic tests
• Continuous path monitoring with alerts shows your
connectivity works as planned and alerts you when
it does not
• Continuous monitoring of packet loss, latency and
jitter with alerting means you are already on it
before your customers experience any degradation
• Automation could be triggered by alerts from the
tests and do it for you
• State of the internet measurements can help you
quickly determine if an alert from a test from your
network to an internet destination is due to internet
weather or if you need to take action inside your
network.

Volume
• You will need to have a simple check of the
ratio and the volume of traffic if your peering
partner’s policy requires it. However it is more
important to have a traffic forecast. What is
the expected traffic growth? When you know
this, you can discuss the capacity of the
connections with the peering partner.

Conclusion

21.
• We have identified a routing issue and documented a hairpin issue in the current setup.
• We have documented the consequences of the issue by showing latency data.
• The solution is a new connection in the NYC metro.
• Since traffic is growing very slowly, there is not an immediate need for more capacity so, if fixing the
hairpin is not important for the peer, we can:
• Offer to pay the cross connects, or
• Suggest a session on an IXP in the metro.
• If the status quo is unacceptable to us, our BATNA is to buy local transit and move the traffic to that
connection.
