Packet Flight: User vs Youtube

This is a visualization of the network packets of a YouTube video, slowed down 12 times. You can clearly see the handshake, some odd client/server negotiation, and the full ramp-up.

Created using Packet Flight:

Each flying circle represents a network packet. The small green ones are control packets: ACK, SYN, etc. The larger blue ones are data packets.

The data is from a real tcpdump of the first 4 seconds of Rick Astley's music video.
