We all have heard the perennial complaint, “the network is sooo slow.” A primary reason is the inelegantly-named bufferbloat – caused by a bad router that queues up too much data (“the router gets bloated because it buffers too many packets”). The good news is that a fix has been known for quite a while
Ahhh… the memories… Back in the day (around 1978), I had one of these beauties. All you had to do was place the telephone handset into those cups (really! [1]), dial up your favorite server, and Presto! You were on-line at 300 bits per second. And for only $139 – it was heaven! While rummaging
I have reworked my blog so that the primary domain name is “Random Neurons Firing” (instead of the pedestrian richb-hanover.com). Same content, but a better name.

Update – November 2017: Added descriptions for the other tools I had investigated.

The Battle for the Net site https://www.battleforthenet.com/ no longer seems to have the telephone form(!) But… Boing Boing does. Go to https://boingboing.net/.

Hat tip to Ro Khanna (@RoKhanna on Twitter) for this… A Portugal ISP (with no net neutrality constraints) appears to be charging 4.99€ (about US$5.86) per month for access to social media. And another 4.99€ for streaming video (Youtube, Netflix, etc). Oh, and another 4.99€ for streaming music. And additional charges for other kinds of
[Part of the series of blog postings on Netflow] Netflow is a network protocol invented by Cisco that provides granular visibility on network utilization. Routers and switches send (“export”) Netflow datagrams that summarize traffic through them to a Netflow Collector program that displays the data. This gives visibility into “who’s using the network?” Virtually all
