Question Posted on Twitter (25 August 2021):
"I'm doing some research and need your help...
When you were new to peering, what was the most useful / helpful info to start your peering journey as a network?
What is the most important thing to know about IXP's?
What info do you currently find useful?
Do you have any tips for the newbies in the community?
DM me if needed."
Open, Restrictive n Selective peering policies I think.
1. What are you trying to solve for should be the first question you ask yourself.
2. What IXs are available in your current region and what networks can you reach.
3. How much traffic you are delivering over $ links and how much traffic can be shifted to PNI.
Learn the tools of the trade. To get peering, be a well prepared peer. Be peerable. Get your AS and IP registry records up to date, do RPKI, register in PeeringDB.
I once wrote thus to explain the basics …. Another thing is that transit is the default for a network. Peering is what happens when you have transit, but realise you can directly interconnect with someone, so you both don’t have to buy transit.
I would say the first thing is understanding the data of your network (flow and routing): where do your packets go? It doesn’t make sense to peer everywhere and may cause administrative overhead. Identify the reasons: cost savings, reliability, performance. There’s a dynamic and power balance between ISPs and Content Providers. In general, it’s easier peer with a CP. IXPs governance is very different between regions. The reputation and quality of the network can vary quite a lot.
Don’t assume ppl know what they are doing. Give them sample configs. Encourage route server usage. Support good traffic engineering communities on the RS.
Understanding the whitepaper <the art of peering> by Bill Norton @DrPeering. The 19 peering tactics were essential for me.
The technical part is reasonably well documented, the human part negotiating with peers was the most difficult to learn.
Read our 10 reasons to peer (DE-CIX)
Understand your traffic and what you’re trying to achieve, be aware of the whole spectrum of costs involved and always keep the experience of your customers in mind.
Understanding IP network technical and commercial relationships, e.g. why some peer, why some don’t. Being able to find information & resources that both assist with troubleshooting and planning.
1. The peering community was ready to help, Both locally and internationally.
2. The art of negotiation with peers, the human part is the most important without you have no peers. Peering book is amazing.
Often made mistakes by economists, regulators, traditional telco is that they look at who send the traffic. For transit and peering the direction and balance of traffic is irrelevant, it is the capacity needed. (though people made cute policies about it).
