We had been using R1.2.3 "print tip lowess function" as described by Terry Speed's group to normalize microarray data and up until this week the commands we were using were working fine. First, we load our data using arrayname<-read.table("filename", header=T) and then check that the table is OK. We format the data list using setup1<-init.data() and usually get a

Hi, I'm trying to modify the stp kernel files in order to implements the RSTP. I've already modify the bpdu format like this : ------------------------------------------------------------------------------------------------------------------------------------ typedef struct { int topo_change = 0; int proposal = 0; int port_role[2] = {0,0} ; //role du port ?metteur du BPDU

I saw some big mistakes, here's the correct version : -------------------------------------------------------------------- void br_send_config_bpdu(struct net_bridge_port *p, struct bpdu *bpdu) { unsigned char buf[42]; buf[0] = bpdu->bpdu_header.protocol[0]; //0x00 buf[1] = bpdu->bpdu_header.protocol[1]; //0x00 buf[2] = bpdu->bpdu_header.version; //0x02 buf[3] =

This is a revised version of Kishore's patch to set message age appropriately in STP configuration packets.

This is the 2.4 version which incorporates the observations from Kishore about 2.6. The existing 2.4 code set the age properly, but did not increment correctly for HZ=1000 and could send a stale (expired) configuration.

I have noticed a change in the linux bridge implementation between 2.1.15 and 2.1.17. Specifically, I do not think BPDU's (generated from another bridge) are passed across the bridge when STP is disabled. I think this relates to the LLC handling of BPDU's directly invoking br_bpdu_rcv. In 2.6.15, the br_handle_frame function would pass a BPDU to the br_handle_frame_finish function

Hi all, I work on a SOC based on Micrel/Kendin KS8695 based on ARM9. ( http://micrel.com/page.do?page=product-info/sys_on_chip.jsp) This component has 2 network interfaces. One is connected to a 5 ports switch. eth0 eth1 => switch port1,2,3,4 I want to make a bridge with these 5 ports but my problem is that the network driver only install 2 interfaces. The KS8695 network switch can be

When we create an L2 loop on a bridge in netns, we will see packets storm even if STP is enabled. # unshare -n # ip link add br0 type bridge # ip link add veth0 type veth peer name veth1 # ip link set veth0 master br0 up # ip link set veth1 master br0 up # ip link set br0 type bridge stp_state 1 # ip link set br0 up # sleep 30 # ip -s link show br0 2: br0:

This changes the message_age_timer calculation to use the BPDU's max age as opposed to the local bridge's max age. This is in accordance with section 8.6.2.3.2 Step 2 of the 802.1D-1998 sprecification. With the current implementation, when running with very large bridge diameters, convergance will not always occur even if a root bridge is configured to have a longer max age. Tested

Hello all, I'm trying to install a VB application that plays out pre-recorded voice messages (.wav). It was custom made for my employer with VB5.0 for Winnt.

Hi, I tried to send the BDPU at less than 1 second in a STP implementation. When I look at STP info with brctl in tells me that the bpdu are send under the second but in fact it's "only" every second. Is it because we can't send BPDU less than 1 second or something else ?
