Wireshark: Packet Loss and Recovery

Wireshark: Packet Loss and Recovery

English | MP4 | AVC 1280×720 | AAC 48KHz 2ch | 1h 23m | 254 MB

Learn how to use Wireshark, the powerful protocol analysis tool, to deal with packet loss and recovery, so you can keep traffic moving. Instructor Lisa Bock begins by reviewing normal traffic, comparing TCP, a connection-oriented protocol, with UDP, a lightweight connectionless protocol. She then moves into discussing network latency, packet loss, and throughput; TCP and UDP packet loss recovery; misconfiguration issues that can cause an interruption of end user experience, along with malware; and more.

Topics include:

  • TCP and flow control
  • Differences between TCP and UDP
  • Dealing with packet loss and delay
  • Explicit Congestion Notification (ECN)
  • TCP packet loss recovery
  • Fast retransmission and recovery
  • UDP packet loss recovery
  • Bursts and packet loss
