i was in a class on apache web servers and learned a bit about
the backend of the internet, such as servers, server farms (where
big warehouses in freezing temperatures store many different
companies web servers in an ultratight environment. like a big
freezer as i remember.
then information got into the routing infrastructure of the
internet. i remember when the internet 'backbone' of supercomputer
centers were (and maybe still are) the major structure of the
traffic that passes through the network, geographically is my
guess, at least when looking at a map of the US and where these
big nodes are. but with the increase of broadband (i'm guessing)
and thus more traffic, and more Routers, the technology has
changed, and become more complex.
if anyone on the list could explain how a router works today,
it would be much appreciated. i am trying to remember what was
said to me about routers today, what they do. basically, i think
it was said these used to be dumb devices, passing through data,
but now with so many addresses and options, they are now dealing
with the entire addressing system of the internet, where to route
the data-traffic to, and need to process this data before sending
a stream in a certain direction. also, it seems these routers are
also networked on the backside together, working together to make
such decision-making faster and more efficient.
this whole hardware/infrastructure side of the internet is mostly
invisible, and i imagine, largely misunderstood or invisible to
the average user who is not a techie visiting the web server farm
with toolbox and snap-on keyboard to configure servers, etc.
but any resources online describing this section are of interest,
please forward to ~e.org as eventually such resources could be
put in one place to help clarify how routing works with millions
if not someday billions of devices connected, in seemingly real-time.
