Net Sound Protocols
NetSound, or the stetho, translates the different communication protocols into MIDI sound data based on Net traffic data from output of TCP dump command. If you are not familiar with protocols and what they are, please read the explanations provided below.
By clicking the entries below, you can hear the various sounds assigned to the different protocols.
ICMP request (Ping-1)
Ping-1 is part of the Internet Control Message Protocol (ICMP), used for managing the network. For example, it is a signal sent to assess whether the network you would like to access is operational or not. It is like a submarine's sonar.
ICMP request (Ping-2)
Ping-2 is the sound heard in response to the Ping-1. The time lag between sending and receiving the signal indicates how busy the network is. If you hear this sound, it means that someone at the Ohno Lab is checking the status of anther network. Thoughtless use of these requests to servers is not good Net manners.
RIP
RIP is Routing Information Protocol, used for controlling routing to indicate appropriate host computers. The protocol works as if it makes the traffic signals change for online data transfer. You can hear it every 30 seconds.
NTP
NTP is Network Time Protocol. Important for maintaining the synchronicity of each computer on the network. It also can be heard at regular intervals.
FTP
File Transfer Protocol(FTP) is a widely used protocol for downloading and uploading, e.g., files onto servers.
HTTP
HTTP, or Hyper Text Transfer Protocol is widely used by Internet users for enjoying home pages. (Link to the previous page.)
NNTP
Network News Transfer Protocol(NNTP) is a protocol used for electronic news and can be heard when someone is reading the news at Ohno Lab. As it is a continuous transfer of various data, this can be somewhat noisy.
NFS
Network File System is used to enable working on host machine files from terminals. It can be heard often from the start of research day at the Lab. NFS is widely used at Ohno Lab.
X-window
This protocol is used when using an X-terminal. You can hear it every time someone at the Lab uses a mouse or a keyboard.
* E-mail related protocols are not included on this demonstration version although e-mail is widely used at the Ohno Lab.
* The sound data is created by the musician Suguru Yamaguchi.
