Flow Chart

Hello This is my first post in this list. I have the follow situation: I have a multilateral peering, and I´m need to plot a graph showing how many traffic is going to or comming from each member of peering. For example: I have the AS61222, and in the peering there is the AS61333. This AS have other peerings, And my AS (AS61222) use the AS61333 as transit. And because it is a peering, by just one interface of my router, I can see just the whole traffic, to AS61333, and another members of peering. I was seeing some thing in JKFlow, but I did not found any thing. Do you have any experience in a case like this? Thanks -- Alexandre Coconesi
