SDN 101: An Introduction to Software Defined Networking
Discover the advantages of SDN.
SDN has quickly become one of the hottest trends in IT. But not all SDN solutions offer real software-defined functionality. As more enterprises consider SDN, they want to know, “What is SDN? And what are the real benefits?” If you're ready to explore the advantages of SDN, and want to know how it should be implemented within your enterprise, start by reading our introductory white paper.

At home I cannot use my wifi. Never could. Now I have an android mobile phone. It cannot use the wifi. If I start Windows, I can use the wifi, so I rule out hardware failure.
My wifi connection shows a dns of 192.168.1.1 (see screenshot). Both my laptop and my mobile say they are connected to the router wifi. But they never get to the internet.
Do you think this may be because of dns setting? I can call up 192.168.1.1 but I cannot see anywhere to change the dns.
Someone told me I need bind, whatever that is, and an entry in /etc/named.conf There is no such file on my computer. Looking at processes, I do not see bind up and running. But the dsl connection works fine.
Hang on, I'll have to start the other computer. But my wireless works in the office, no problem. Haven't had a chance to try the new mobile, it's a holiday here! New Year!
pedro@pedro-bedro:~$ nslookup baidu.com
well that's working there... that's presumably network-manager intercepting the dhcp details and setting up dnsmasq on the client. It may be insightful to run "tcpdump -i <wifi interface name> -vn port 53" whilst running those lookups and posting that output, seeing where the DNS requests are actually gong.

For Release and Renew, if no adapter name is specified, then the IP address
leases for all adapters bound to TCP/IP will be released or renewed.

so you've a ppp interface on windows? Please describe more detail about your LAN and internet conenctivity as there's clearly a hell of a lot more going on on windows that a typical domestic ADSL connection.
Nothing complex here, really, just a router with 3 sockets for dsl cables, and one for iTV. The router also has wlan. Using Ubuntu or Fedora, I have never been able to connect to the wifi. It sees it, and says I am connected. But can't access the internet. And now my Android phone can't access the internet either. What is wrong? In the office is exactly the same set up, and I can access the wifi no problem with Ubuntu or Fedora.
Using Win, we automatically make the wifi connection. But it will not work unless we also make the dsl connnection, even though the cable is not plugged in! The dsl connection is called nanjing on the other laptop. We have to click it and say connect, it does not complain that the cable is not plugged in, like nm would do!
