More Links, Magic Bandwidth.

This week, for the first time ever, I witnessed 20 simultaneous nodes running in Jalalabad. In the last week there have been two new links, and now multiple groups are working on adding links. Very cool. The link on the right is the newest one. Where is the water tower? It's not visible at all, but the connection works. H &M are definitely stretching the limit of what we thought would be reliable, but if it works, it works...

Even cooler is the network is starting to generate enough load that some of the network services we've put in place are starting to work their magic. JBad has a guaranteed 2Mbit full duplex sat connection. In practice, that means that download speeds max out at about 252KByte/sec (KBps), with occasional peaks above that value. In order to increase the effective bandwidth, we have a local cache that saves pieces of the internet that are commonly accessed and serves them back locally. For the first time last week, we saw the local internet traffic exceeding the uplink bandwidth enough that it showed on the traffic graphs (node tab on this page: fabfi.fablab.af/stats.php?). Eventually we hope to capture most of the real-time traffic inside the fabfi net...
