Trace Data Analysis (only in Standard/Pro Version)

This section explains about how to analyze the data of a NetSim trace file.

How to set filters to NetSim trace file

Step 1: Open the trace file. (In this example packet trace is opened)

Step 2: Go to Data menu and click on filter icon to enable the auto filter.

Step 3: Click the arrow in the header of the column you want to filter. In the list of text or numbers, uncheck the (Select All) box at the top of the list, and then check the boxes of the items you want to show.

For example, click on arrow of SOURCE_ID and uncheck the “Select all” check box and select NODE 2 then click on ok.

All the rows which are having NODE 2 as source id will be shown.

Typically filters can be set to observe “Errored/Collided/Successful “packets, packets of destination and packets of source.

Observing packet flow in the Network through packet trace file

Step 1: Open the packet trace file.

Step 2: Set the filter.

Step 3: Click the arrow in the header of the column PACKET_ID and uncheck the “Select all” check box and select the packet id which you want to observe, for example 1, and then click on ok.

Scenario is as shown below and traffic flow is from Wired Node 1 to Wired Node 2.

Flow of packet 1 can be observed from the packet trace as shown below.

Note: In the trace file device IDs are shown not device names. Wired Node 1’s ID is 2 so it is Shown as NODE-2, Wired Node 2’s ID is 3 so it is shown as NODE -3, Router-1’ ID is 1 so it is shown as ROUTER-1. Device IDs are shown on the top of the device icon in the above scenario.

In a scenario source and destinations are fixed but transmitter and receiver are changed. For example in the above scenario NODE-2 is the source and NODE-3 is the destination, but when NODE- 2 sending the packet to the ROUTER-1 then NODE-2 is the transmitter and ROUTER-1 is the receiver. When ROUTER-1 sending the packet to the NODE-3, ROUTER-1 is the transmitter and NODE-3 is the receiver.
