Project Shield – a DDoS protection layer from Google

Project Shield is not a mainstream service yet, just an idea that Google is trying out, but still, I think it’s worth a mention.

Project Shield is an initiative launched by Google Ideas to use Google’s own Distributed Denial of Service (DDoS) attack mitigation technology to protect free expression online. The service allows other websites to serve their content through Google’s infrastructure without having to move their hosting location.

Google adds QUIC protocol to latest Chrome build, delivering HTTP over UDP

Google adds QUIC protocol to latest Chrome build, delivering HTTP over UDP

Here are the QUIC highlights Google wants to emphasize right now:

  • High security similar to TLS.
  • Fast (often 0-RTT) connectivity similar to TLS Snapstart combined with TCP Fast Open.
  • Packet pacing to reduce packet loss.
  • Packet error correction to reduce retransmission latency.
  • UDP transport to avoid TCP head-of-line blocking.
  • A connection identifier to reduce reconnections for mobile clients.
  • A pluggable congestion control mechanism.

In other words, QUIC is yet another protocol that Google is building to help speed up the Web. It has already done so notably with its SPDY protocol, which is now the foundation of the upcoming HTTP 2.0 protocol.

Corny network engineer jokes

A colleague sent me a link to this list of network engineer humor.  If you are not a networking guy, you should probably skip altogether, cause these are pretty geeky.  I haven’t got all of them, but a few that I did are actually quite good.

“Knock Knock” “who’s there?” “Denial of Service Attack” “Den…?” “Sn(kRzIhAw]BoKaoOv0liZPhl~FaLoaSa*AgSeaLp|ExleT…” – @MattGordonSmith

An IPv6 packet walks into a bar. Nobody talks to him. @fsmontenegro

A tcp packet walks in to a bar and says “I want a beer”, barman says “you want a beer?” and tcp packet says “yes, a beer” @stevie_chambers

A Network Engineers tell a joke in a full bar. One man laughs. They start talking about NX-OS and have a blast. @icemarkom
