Time Sequence tab

The Time Sequence tab provides a time sequence diagram of the TCP conversation selected on the TCP Conversation view. You can view the diagram to understand the packet transmission mechanism in a TCP conversation. Grey is for packet from node 1 to node 2 and yellow is for packet from node 2 to node 1.

Toolbar

There are only three items on the toolbar of this tab, described as below:

Item	Description
	The type to display the sequence number of the byte flow in data transmission, including: Show Absolute Seq: Shows the real sequence number in the packet. Show Relative Seq: Shows relative sequence number with the first packet of the conversation being 0.
	Refreshes the diagram. If the interval is set to Manually Refresh, display will update only when the Refresh button is clicked.
	The number of packets of the conversation.

Time sequence diagram

The time sequence diagram is organized by six columns which are described as below.

Column Description

Relative Time The time from the timestamp of selected packet to that of the first packet in the conversation, with the first packet of the conversation being set as the reference object.

Summary-> The information about sequence number, acknowledgement number, next sequence number of the packet sent by node 1.

Node 1-> The window size information of node 1. A window size of 0 indicates that Node 2 should stop transmitting.

Flag and Load Length Flags that are control flags in TCP segment header and load length which is the size of the data portion of TCP segment.

<- Node 2 The window size information of node 2. A window size of 0 indicates that Node 1 should stop transmitting.

<-Summary The information about sequence number, acknowledgement number, next sequence number of the packet sent by node 2.

You can double-click the conversation selected on the TCP Conversation view to open TCP Flow Analysis window to know the details of the conversation.
