Analysis Method A filter was applied to each trace to display only the TCP connection between the source and destination. The focus of both analyses 1C consists of four algorithms : Slow Start, Congestion Avoidance, Fast Transmit, and Fast Recovery. The traces capture file uploads to social media sites - and The files were uploaded from a laptop over a home wireless connection. This paper contains an analysis of congestion control mechanisms observed in two network traces captured using Wireshark version 1.4.6. x Receiver-advertised flow control mechanisms x Throughput and round trip time of the connection The traces captures are for file uploads to two remote social media sites and Overview 8 1 he Robustness L ! Transmission Control Protocol (TCP). A detailed packet level analysis of areas within each trace indicating congestion issues will be performed. The paper will analyze the following aspects: x Basic slow start and congestion avoidance mechanisms x Fast recovery: a variation of the TCP slow start mechanism that uses fast retransmit followed by congestion avoidance.
Text of An Analysis of TCP Congestion Control Mechanisms using WiresharkĪn Analysis of TCP Congestion Control Mechanisms using Wireshark Jayesh Naithani SEIS 715 - Spring 2011 Abstract This paper contains detailed analysis of two Wireshark traces for investigating the behavior of TCP congestion control mechanisms. The paper analyzes the following aspects: Basic slow start and congestion avoidance mechanisms Fast recovery: a variation of the TCP slow start mechanism that uses fast retransmit followed by congestion avoidance Receiver-‐advertised flow control mechanisms Throughput and round trip time of the connection The trace captures are for file uploads to two social media sites and The paper was a project for a course on Computer Networking Protocols (SEIS 715) at the University of Saint Thomas, Saint Paul, Minnesota. Search for "ip to asn mapping" and you will find many open source ones.This paper contains a detailed analysis of two Wireshark traces for investigating the behavior of TCP congestion control mechanisms. If you have some other problem, consider finding a CSV of the address ranges of the AS numbers, and use awk/python/excel/whatever to do what you need. If you can't get Wireshark to look at the packets directly, and you have Cisco routers in a suitable place, you can use Netflow to capture the packets and export the capture from the router and import it into Wireshark for analysis. You will also be able to see the Autonomous System information on the per-packet analysis, and use it in filters and so on.

If the columns marked AS Number and AS Organization are blank throughout, you need to configure the database for looking these up. You might need to copy and paste into Excel to sum the bytes per AS, or use some awk/python one-liner. In the menu choose Statistics > Endpoints and you will see a window like this:
You can certainly do this with Wireshark.
