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.

I have a linux gateway based on RedHat 7.3 with 3 ethernet cards, one (eth0) is for ADSL modem, the other two are for my little internal network. To these two ethernet cards, there are 2 Windows XP computers connected and I have a little problem.
When Linux is started before WinXP, I normally get IP from it, because of Win demand on startup. But if I reboot Linux while Wins are working, then WinXP assumes some strange IP (because it looses it's IP no.). After Linux comp. comes up, it doesn't automatically offer IP numbers to these WinXP computers. Is there any way, that Linux will make some kind of broadcast like "I am now server, alive and working, please request Your IP numbers!"?
Thank You for Your post. I forgot for the ipconfig options but this is not the way I want. Right now I renew Windows IP by double clicking the network icon, then change to tab support and click button Repair. But I do not want to do anything from Windows side, I need that Linux box announces to all computers on internal network "Ask me for Your IP".
Sadly this is not the way that DHCP works. All DHCP interaction is driven by the client. If you switch off the DHCP server then boot the clients they will assume a 169.254.x.x link local IP address. As mentioned above to renew the IP address you must ipconfig /renew. There is no way around this that I know of. DHCP is considered to be a network critical service and so is assumed to always be present.
How many DHCP clients do you have? If it is only a couple then create 2 ranges. 1 fiexed XXX.XXX.XXX.100 - XXX.XXX.XXX.199 are fixed IPs then get the DHCP server to assign addresses XXX.XXX.XXX.200 XXX.XXX.XXX.249
I have currently only two WinXP comps, but in the future it can be some more. I was thinking also of fixed adresses; but maybe in this occasion I could also use WinXP IP settings when network is unavailable... Maybe this could do the trick.
Baldy, thanks for Your input also. Thinking about DHCP this way explains this. But still, isn't there no command that i should write in rc.local or dhcpd script when starting to maybe forcibly give IPs?
