Networking advances of the aughts?

What's new in networking over the past ten years? My reason for asking is that
I'm re-taking a Cisco networking course to keep my skills up to date, but I
have no expectation that the teacher and course material are up to date. I'll
start with a few things that were not in the Cisco material when I last took
the course.
- Netflow packet dumping.
- VPNs are far
more popular than they used to be. Hardly anyone had them before; now it's expected
that anyone knows how to set them up.
- Routers have gained enough features that traditional routers are called
Layer 3 Switches, which raises the question of what new features are
expected to be in a proper "router".
- Gigabit Ethernet and the move from Cat5 to Cat5e and Cat6 were a significant change.
There is also Cat6A for 10,000baseT.
- BGP
is the routing protocol used on the Internet. This is not new, but it was not
covered in the Cisco material.
- Lots of places are punching big holes in their security with wireless
routers and exploitable wireless devices (like printers) in the trusted section
of the network. MAC whitelists and encryption are musts for access points, but
some of the standard encryption methods such as
WPA
and
WEP have
been compromised.
What else is new? Also, what are some good news websites for reading about networking advances?
