For NAS on the Home Network, it turns out GbE matters

For our computers at home we have a small network based on a standard wireless dual radio N/G router with 4x 1Gb Ethernet ports. However wireless performance in my office which is about 30 feet away from the router is poor (maybe 2Mb/s). We fixed this by creating a Ethernet over Power Line network (using the Netgear XAVB101) which works fine for most applications.

The one area that didn’t work well was transferring large files from and to our Network Attaches Storage (a 1 TB Buffalo LS-WTGL, predecessor to this model). Transfer speed from my MacBook Pro maxed out around 20 Mb/s. In other words filling the 1TB drive would take about 4.5 days. That’s a bit slow. How to fix it after the break.


Joining Stanford

Hector Garcia-Monial and myself at Graduation.I am happy to announce that this week I have joined Stanford University as a Consulting Assistant Professor. This may come as a suprise to some people, as I am not exactly your typical academic. Those people would be correct, my job here is not primarily about teaching. The main reason I am joining Stanford is OpenFlow, and it is one of the most exciting technologies I have seen in networking for a long time.

OpenFlow is exciting in two ways. First, it allows you to run new protocols and algorithms on production networks. Before OpenFlow this was very hard, as modern routers have no API that gives access to this low level functionality. Second, it allows you to make centralized yet fine grain routing decisions. This has huge advantages in some areas such as security, data centers or mobility.
