[ixpmanager] Peering Matrix features (was: Re: Peering Matrix)

[Andreas Polyrakis]

Hello Nick, all,

We, at GR-IX, are currently using a custom peering matrix tool, created 
ages ago. Our peering tools is based on purely on sflow data. The 
association between sflow and customers is done through a MAC address 
database. A separate peering matrix is created for v4 and v6.

https://www.gr-ix.gr/peering-matrix/

We are now considering redesign it from scratch. The most important 
limitations of this approach is that, due to our infrequent sampling, 
some "peerings" may get missed, esp between large and small customers. 
Also, as the number of customers increases, the full matrix is hard to 
read; a different UI is necessary.

Quite a while ago we evaluated the ixpmanager peering matrix. If I 
remember correct, we spotted the following two limitations
- it was using sflow to spot peering in control plane (bgp sessions), 
rather than monitoring the data plane. On switches with high sampling 
rate, such sessions would be easier to miss.
- It was assuming that all members on the route servers peer with each 
other.

In our new peering matrix tool, we consider the following enhancements
(a) data-plane sflow will be used to identify baseline peerings
(b) route servers will be used to identify additional peerings, missed 
by sflow, but it will need to verify that the peers actually exchange 
(advertise/accept) prefixes
(c) Inspired by the RIPE country jedi tool 
(http://sg-pub.ripe.net/emile/ixp-country-jedi/latest/GR/ixplans/index.html), 
we would like to explore using ripe atlas to augment the peering matrix; 
eg find missing peerings, find private peerings, explore routing of a 
specific AS behind a member etc.
(d) augment the UI to be able to visualize such data

Coming to IXPmanager, I wonder if you have any new features on store for 
the peering matrix. If yes, can you please elaborate?

In any case, we would be happy to co-operate and contribute back.

Regards,
