Briefly: Network Topologies

Things I learned today: network link-layer topology makes a huge difference for wireless.

My file transfers via 802.11n from one laptop to another were pretty slow: max sustained throughput was 3–4 MB/sec. As an experiment in solving unrelated AirPort base station association issues, I plugged one laptop (that’s already wired up to the TV as a media center of sorts) into the base station via GigE. Because the AP no longer has to negotiate with two clients on the same slice of spectrum for network traffic, my inter-machine transfer rate jumped to 15–18 MB/sec.

The network layout looks something like this:
