Google QUIC is a Secure UDP Protocol Aiming to Replace TCP + TLS

A lot of traffic over the Internet goes through  secure https connections. Under the hood this requires a 3-way handshake to establish a TCP connection, followed by even more packets exchanged between the client and server to negotiate TLS in order to establish a secure connection.  Google is now working one the new experimental QUIC protocol that uses the “send and forget” UDP protocol, together with its own crypto, and its own way to making sure the connection is properly establish. The whole idea about QUIC is to reduce the effect of latency (e.g. ping time) by exchanging less messages to achieve the same secure connectivity. For example, if there’s a 200ms latency between a server and a client, and if a TCP connection requires 4 packets, while a QUIC/UDP connection requires only 1 packet, you’ll save about 600ms. One downside with UDP according to Jim Roskind, designer of QUIC, is that UDP ports are blocked by some enterprise customers, …

Internet TVs at IFA Berlin

Even though Android tablets were widely hyped, IFA also had other interesting devices on display. Among them, internet TV is starting to take off. I would have expected some Android set-top box to be shown off, but some manufacturers may prefer to attend IBC 2010 10-14 September 2010. Interestingly the 2 videos below only provide integrated internet Tvs, i.e. without external set-top box. Philips demo’ed an improved version of Net TV, a standard for internet television. Here’s the LG’s Smart TV system for Web-TV and apps on High Definition Television. They have a really cool “magic” remote. (Wii-like remote). This is still a prototype but it looks promising.
