Google researchers have recently announced a new initiative called SPDY aimed at improving the performance of HTTP by reducing the delay between a HTTP request and a response. SPDY also allows to multiplex several requests over a single TCP connection. google intend to release a prototype implementation for a server and already has a chrome plugin.

In a recent presentation at the LADIS 2009 workshop, Jeff Dean, Google Fellow in Google's Systems Infrastructure Group, gave an interesting talk on the large scale distributed systems that are in use inside google. Although the presentation does not reveal trade secrets, it provides interesting hints about some of the issues that google is addressing and the size of their infrastructure.

During NANOG47, Craig Labovitz and his colleagues unveiled a new study about the traffic distribution in the Internet.

In contrast with most scientific studies that analyses Internet traffic from a few measurement points, this study was able to analyse statistics coming from more than 110 ISPs for a total aggregated throughput of 14 Tbps. The major findings of this study are :

- It seems that Apple airport Gateway implements full IPv6 (by tunnel?)
- NAT v4->v6->v4 an issue ? It is temporary and an incentive for full IPv6... and it's not worth than v4->v4->v4
