we are planning to run roofnet in x86 with atom cpu. I think run click only in mips router it can't be more efficient. 2009-12-18

I use click roofnet process the 802.11n packet. test it use IxChariot. find about 90Mbps, click use 100% cpu. I use routeros 433AH boardband.the cpu is MIPS 680Mhz. I don't know how to make click have more eiffciency. please help me, Thanks very much. -- Yongheng Qi Mobile: +86 1390 119 7481 ------------------------------ Message: 2 Date: Fri, 20 Nov 2009 10:31:27 +0800 From: Yongheng Qi <[email protected]> Subject: [Click] click optimize efficiency To: click <[email protected]>, click <[email protected]> Message-ID: <[email protected]> Content-Type: text/plain; charset=UTF-8 Dear everyone.

Unfortunately it looks like that there is a bug, apparently related to the interactions between kevents and select/poll. The OS X tun/tap devices don't currently support kevents, and therefore click tries to back off to use select/poll. However, once it gets to the actual poll in master.cc, something has gone wrong and I get a an assertion failure on line 850 in master.cc: Element *read_elt = (p->revents & ~POLLOUT ? _read_elements[fd] : 0); This results in an assertion failure, with this trivial script: click -e "KernelTun(192.168.15.1/24) -> Discard" Assertion failed: (i>=0 && i<_n), function operator[], file ../include/click/vector.hh, line 184. Abort trap My gut feeling is that the bug may line somewhere in master.cc Master:add_select, in the code that tries to make sure that one can fall back to select/poll in the case of kqueue error. But I may be wrong. In any case, when tracing the execution in opening the tun/tap device, the kevent system call at line 602 of master.cc fails, causing the _kqueue socket to be closed and made unused. However, much before that I can see with ifconfig that the tun/tap interface is indeed open and correctly ifconfig'ed. Anyone an idea where to continue debugging? Or would it be easier to add KEVENT support to the Mac tun/tap kexts? --Pekka Nikander ------------------------------ _______________________________________________ click mailing list [email protected] https://amsterdam.lcs.mit.edu/mailman/listinfo/click End of click Digest, Vol 77, Issue 19 ************************************* _______________________________________________ click mailing list [email protected] https://amsterdam.lcs.mit.edu/mailman/listinfo/click
