This sequence diagram describes actions taken by TCP to prevent congestion in the Internet
TCP can recover a lost segment quickly by looking for duplicate acks from the receiver.
A summary of all TCP scenarios, just listing client end interfaces.
HTTP sequence diagram for loading of the EventHelix.com home page. The page load is captured in two threads. The sequence diagrams for individual threads are also included.
This sequence diagram based tutorial describes the web caching feature on the web browser side.
The interactions involved in web page redirection using HTTP 302 code are covered here.
HTTP Post handling and lower level TCP interactions are shown in this diagram.
Here we explore the sequence of interactions in a typical FTP (File Transfer Protocol) session. Individual sequence diagrams for interactions on Port 20 and 21 are also included.
Telnet sequence covers terminal option negotiation and server handling.
SMTP E-Mail pdf
Sequence diagram describing SMTP e-mail send. DNS MX record interactions are also covered.
Interactions between a POP3 server and client are described here.
