Overview of this book

This book contains practical recipes on troubleshooting a data communications network. This second version of the book focuses on Wireshark 2, which has already gained a lot of traction due to the enhanced features that it offers to users. The book expands on some of the subjects explored in the first version, including TCP performance, network security, Wireless LAN, and how to use Wireshark for cloud and virtual system monitoring. You will learn how to analyze end-to-end IPv4 and IPv6 connectivity failures for Unicast and Multicast traffic using Wireshark. It also includes Wireshark capture files so that you can practice what you’ve learned in the book. You will understand the normal operation of E-mail protocols and learn how to use Wireshark for basic analysis and troubleshooting. Using Wireshark, you will be able to resolve and troubleshoot common applications that are used in an enterprise network, like NetBIOS and SMB protocols. Finally, you will also be able to measure network parameters, check for network problems caused by them, and solve them effectively. By the end of this book, you’ll know how to analyze traffic, find patterns of various offending traffic, and secure your network from them.

Video over IP and RTSP

As per the internet report published by internet Society, more than 70% of global consumer internet traffic is IP video traffic. In the world of entertainment and education, video content is very prevalent and leverages the maturity of IP network by using IP as transport media for video content delivery. Various codecs are used to encode the video content into bit streams and use RTP as the transport protocol for end-to-end video data delivery.

The video traffic can be streaming video or can be a one-to-one video call. While in either of the cases, RTP is used as the protocol for video data packets, different control plane signaling protocols can be used to establish the video call sessions. For example:

  • SIP can be used as the signaling protocol for video calls
  • RTSP can be used as signaling protocol for streaming video.
