I finally have the courage, and publish my first Blog.
Let the first story be serious and fun. Let me talk in my first Blog about seriously heavy pinging; but not from a Controller to a Host and back; but from the Far, Far Away Universe to us. Let's talk about FRB, Fast Radio Bursts.
It seems that billions of years ago, a controller, say a DEC PDP 11 (no, no, that's only 30 years ago), sent a large bright burst of radio waves into its surrounding space. Could that have been the first Trace-route in history? And the radio waves traveled past galaxies, star clusters, avoided black holes, and, PING, arrived in 2012 at this monster of the radio telescope in Arecibo, Puerto Rico.
OMG, 16 more flashes, I mean PINGS, in 2015. Ok, now the controller is sending with a -t. And we get nine more PINGS (radio flashes) in 2016 (August and September). With this many PINGS, we now know who is doing this, a dwarf galaxy, about 3 billion light-years from Earth. These pings have not the usual 32 bytes of payload, but just a few milliseconds of enormous energy packed in what is now called FRB's (fast radio bursts).
Astronomers and network guys, sorry, network engineers, look at know objects, like stars, black holes, planets, routers, switches, and such objects. With PINGS, you just sit there and see what happen after a ping is pinging. This whole what, when, where, why is unraveling in real-time in front of us.
Fast radio bursts? Hmm. Did I not hear about something like that before.
Indeed, it's called Gamma-ray bursts. Remember, in 1960; US government satellites were hanging low, looking for the high-energy indications of Soviet nuclear tests. And yes, 16 bursts of gamma rays showed up, but no nuclear test. Say what? Ops, the antenna in the wrong direction, these gamma rays came from space. Ah, let's see if this is just an accident. Let's see if we get other PINGS, on a different network; I mean different universe. So, astronomers all over started to watch the skies. And some astronomers in Australia produced a set of PINGS; I mean similar radio bursts. Darned, a week later it was found that they had accidentally left their microwave door open while cooking something. True story! How do you call those pings? PONGS? PING PONG.
So, who is pinging us, a single desktop (no problem), or a whole bunch of highjacked servers (big problem) and should we close that port, avoiding a PING OF DEATH attack? Precisely from where do these 2012 FRB's, as well as 17 others, come.
Casey Law of the University of California, Berkeley, in 2015 and 2016, who led a software project and data-taking developments, and with the help of an optical telescope called Gemini North, found the source to be a galaxy, around 3 billion light-years distant. Not some space invaders, or some hackers in some far away country.
Problem solved. As I said many times if you need to unravel a big mystery in the Universe, a big mystery in the network room, just PING.
