ON THE NET

On the ‘Net: So many selfies, so little self

As the Industrial Revolution began to gain momentum, thinkers often decried technological progress as an “atomizing force” that split communities by emphasizing the individual over the group. Living alone in a crowd is documented in a number of books—including Bowling Alone, Alone Together, and Antisocial Media. Perhaps there is no more poignant expression of atomization than Moby & the Void Pacific Choir’s “Are You Lost in the World Like Me?

On the ‘Net: RFC1925 Rule 6A

The truth is, however, that while protocol designers may talk about these things, and network designers study them, very few networks today are built using any of these models. What is often used instead is what might be called the Infinitely Layered Functional Indirection (ILFI) model of network engineering. In this model, nothing is solved at a particular layer of the network if it can be moved to another layer, whether successfully or not.

On the Web: RFC1925 Rule6

Early on in my career as a network engineer, I learned the value of sharing… For instance, when I could not figure out why a particular application was not working correctly, it was always useful to blame the application. Conversely, the application owner was often quite willing to share their problems with me, as well, by blaming the network. A more cynical way of putting this kind of sharing is the way RFC 1925, rule 6 puts is: “It is easier to move a problem around than it is to solve it.”

RFC1925: Rule 4

The world of information technology is filled, often to overflowing, with those who “know better.” For instance, I was recently reading an introduction to networking in a very popular orchestration system that began with the declaration that: ‘routing was hard, and therefore this system avoided routing’. The document then went on to describe a system of moving packets around using multiple levels of Network Address Translation (NAT) and centrally configured policy-based routing (or filter-based forwarding) that was clearly simpler than the distributed protocols used to run large-scale networks. I thought, for a moment, of writing the author and pointing out the system in question had merely reinvented routing in a rather inefficient and probably broken way, but I relented.
