Re: Measurement data on transit traffic in IP routers?
Hi Chris Your statement makes something of a presumption as to the architecture of a network. In many networks, edge aggregation devices do not participate in backbone routing, but simply pass the traffic they are aggregating into the core. One fairly well instrumented network that does have this edge/core collapsed model is the Internet2 network. You can find a lot of traffic and other data for the network at: http://noc.net.internet2.edu/i2network/live-network-status.html You should be able to extract all the info you need from there. /Andrew Chris Develder wrote, On 2/18/07 5:46 AM: > > Hi All, > > In preparation of a course, I'm looking for reference material (paper, > report, talk...) giving real world data on the amount of transit traffic > (ie. not locally dropped or added, but passing through to other > (backbone) routers) in a "typical" edge router of a core network, esp. > ratio of local vs passthrough traffic (is it 30%, 40%...?) -- I don't > need absolute figures, just realistic estimates of that ratio. > > Any help in locating such references would be highly appreciated. > > Kind regards, > Chris >
