Hi Murphy,I know this basic spanning tree implementation but this is only compatible with NOX version 0.5. I am using openflow version 1.0 in openwrt linux which does not support 0.5 version. So. do u have a spanning tree implementation which is compatible with the NOX supporting openflow version 1.0
I have one doubt that whether routing loops (Routing Module at NOX) can be prevented by this implementation. Because routing module does not flood the packets by (OFP_FLOOD) but it transmits the packet to each and every port except incoming port explicitly when it does not know the destination. thanks,Sachin --- On Thu, 14/4/11, James "Murphy" McCauley <[email protected]> wrote: From: James "Murphy" McCauley <[email protected]> Subject: Re: [nox-dev] Which NOX module should be used for wireless networks testing To: "sachin sharma" <[email protected]> Cc: [email protected] Date: Thursday, 14 April, 2011, 1:07 AM You might want to take a look at the spanning_tree component: http://www.openflow.org/wk/index.php/Basic_Spanning_Tree -- Murphy On Thu, 2011-04-14 at 01:01 +0530, sachin sharma wrote: > > > Hi, > > > I am interested to test openflow in wireless networks where loops are > present in topology.
