How shall i get these flow metrics (srcIp, dstIp, srcPort, dstPort, protcol number, size of first three packets) from the sFlow mininet?

[Mohamed Abbas]

Hi All,

I'm Abbas, a student working on a network analytics project. I'm a beginner to the Mininet and sFlow-rt and I have to deal with these seven features ( srcIp, dstIp, srcPort, dstPort, protocol number, size of first three packets )  for my analytics project from a mini net emulated network. I found the sflow-dashboard app has the following features displaying in a chart. Also, I tried checking the API's provided by the sFlow-rt for the metrics and topology. Since the sFlow is based upon the REST-API's, I think I have to use the REST API's for gathering these feature data but still, I would like to get some suggestion from expert community.

Please let me know which is the best way to gather these features only from the sFlow-rt ( mininet ).

Thanks in advance,

Mohamed Abbas M

sFlow randomly samples packets, so you won't be able to get the size of the first three packets of a connection.The other values can be used to build flows: srcIp, dstIp, srcPort, dstPort, protocol number. The article RESTflow gives some examples using the sFlow-RT REST API.

If you have any further questions, please address them to the sFlow-RT group,

Thanks Peter Phaal for your response.

Is there any other way that can help me fetch the first three packet size of a tcp connection?

Or should I need to try some other flow capture tools on Mininet ? 

Thanks,

You can use tcpdump or wireshark to capture packets on Mininet.
