7/13/2006		6:31:49 PM		Yoo		husni, Abdul Awal 		Yoo says: loss from dvsend is quite low Yoo says: around 10-30 pkts/ 3000 pkts Abdul Awal  says: they r in same campus, i dont know why there are loss?	
7/13/2006		6:31:58 PM		Yoo		husni, Abdul Awal 		Yoo says: some times there could be 40-60 Abdul Awal  says: I am getting 10-50 packets loss	
7/13/2006		6:32:42 PM		husni		Abdul Awal , Yoo		the packets pass three switches between dvsend and dvrelay machines	
7/13/2006		6:33:33 PM		Abdul Awal 		husni, Yoo		ic. could it be case that the switches are overloaded?	
7/13/2006		6:33:44 PM		husni		Abdul Awal , Yoo		may be	
7/13/2006		6:33:52 PM		Abdul Awal 		husni, Yoo		hmmm	
7/13/2006		6:33:56 PM		husni		Abdul Awal , Yoo		but the cpu utilizations are not that high	
7/13/2006		6:36:27 PM		Abdul Awal 		husni, Yoo		even though there are 1 frame/sec, I am experiencing 10-60 packet loss.	
7/13/2006		6:38:21 PM		Yoo		husni, Abdul Awal 		what is the expected rate for -f 30? 4mbps? 	
7/13/2006		6:39:17 PM		Abdul Awal 		husni, Yoo		there should be NO packet loss if 6 Mbps is researved	
7/13/2006		6:40:06 PM		Abdul Awal 		husni, Yoo		*reserved	
7/13/2006		6:40:19 PM		husni		Abdul Awal , Yoo		wait	
7/13/2006		6:40:28 PM		husni		Abdul Awal , Yoo		are you talking about packet loss at dvrelay	
7/13/2006		6:40:31 PM		husni		Abdul Awal , Yoo		or at your side?	
7/13/2006		6:41:45 PM		Abdul Awal 		husni, Yoo		at my side.	
7/13/2006		6:41:59 PM		Abdul Awal 		husni, Yoo		now dvrelay is controlled by Yoo	
7/13/2006		6:43:14 PM		Yoo		husni, Abdul Awal 		today, how much traffic you see dvrelay send to switch? > husni	
7/13/2006		6:43:31 PM		husni		Abdul Awal , Yoo		http://sfc-serv.ai3.net/traffic/sfc-delta-sw/sfc-delta-sw_46.html	
7/13/2006		6:44:01 PM		Yoo		husni, Abdul Awal 		3mbps, is that correct ? > awal?	
7/13/2006		6:45:41 PM		Abdul Awal 		husni, Yoo		actually, it should be less than 4 mbps.	
7/13/2006		6:49:36 PM		Yoo		husni, Abdul Awal 		do you have dvrecv on linux or freebsd?	
7/13/2006		6:49:43 PM		Abdul Awal 		husni, Yoo		oh, arround 3 mbps correct. when there is one frame/sec sending in IPv6, the bandwidth should be 2.9 mbps, for other discarded 29 frames, it send only the audio.	
7/13/2006		6:49:54 PM		Abdul Awal 		husni, Yoo		in windows.	
7/13/2006		6:50:33 PM		Yoo		husni, Abdul Awal 		doesn't have version on freebsd or linux?	
7/13/2006		6:51:25 PM		Abdul Awal 		husni, Yoo		yes, I have, but inthat case we have to attache the dv camera to see the output	
7/13/2006		6:51:39 PM		Yoo		husni, Abdul Awal 		just wanna see loss rate first	
7/13/2006		6:51:53 PM		Yoo		husni, Abdul Awal 		if you have version on freebsd, you can install on sfc-imlsdds	
7/13/2006		6:51:56 PM		Abdul Awal 		husni, Yoo		in windows also we can say the loss rate	
7/13/2006		6:52:04 PM		Abdul Awal 		husni, Yoo		10-60	
7/13/2006		6:52:09 PM		Yoo		husni, Abdul Awal 		it is the hop before satellite 	
7/13/2006		6:52:35 PM		Yoo		husni, Abdul Awal 		if we know loss rate there, we can check loss is from satellite or not	
7/13/2006		6:53:05 PM		Abdul Awal 		husni, Yoo		I really didnt get the point	
7/13/2006		6:53:43 PM		Yoo		husni, Abdul Awal 		i want to check which network cause the loss at dvrecv	
7/13/2006		6:54:00 PM		Abdul Awal 		husni, Yoo		do u want to install dvrecv in sfc too?	
7/13/2006		6:54:10 PM		Yoo		husni, Abdul Awal 		whether it is on satellite or before that	
7/13/2006		6:54:32 PM		Yoo		husni, Abdul Awal 		can you install on sfc-imlsdds? it is freebsd	
7/13/2006		6:54:54 PM		Yoo		husni, Abdul Awal 		and you run dvrecv on both sfc-imlsdds and ait 	
7/13/2006		6:55:08 PM		Yoo		husni, Abdul Awal 		then compare loss you got from both dvrecv	
7/13/2006		6:55:32 PM		Yoo		husni, Abdul Awal 		i and husni will have a meeting with sfc in next 5 mins	
7/13/2006		6:56:28 PM		Abdul Awal 		husni, Yoo		to run dvrecv in freebsd, we should attach a dv-camera.	
7/13/2006		6:56:33 PM		Abdul Awal 		husni, Yoo		but there is another way	
7/13/2006		6:57:38 PM		Abdul Awal 		husni, Yoo		I can install the dvrelay in lmdssd pc, and work as another dvrelay, in that case, we do not need an extra camera	
7/13/2006		6:57:44 PM		Abdul Awal 		husni, Yoo		and we can see the loss rate there	
7/13/2006		6:57:47 PM		Abdul Awal 		husni, Yoo		let me try	
7/13/2006		6:58:18 PM		Abdul Awal 		husni, Yoo		Prof. Kanchana is here. She is asking to follow her test options one by one.	
7/13/2006		6:58:19 PM		Yoo		husni, Abdul Awal 		you will use dvrelay to check loss from hts?	
7/13/2006		6:58:24 PM		Abdul Awal 		husni, Yoo		yes	
7/13/2006		6:58:27 PM		Yoo		husni, Abdul Awal 		pls try	
7/13/2006		6:58:33 PM		Abdul Awal 		husni, Yoo		another dvrelay which will relay to some other pc	
7/13/2006		6:59:04 PM		Yoo		husni, Abdul Awal 		go ahead	
7/13/2006		6:59:08 PM		Abdul Awal 		husni, Yoo		can u please provide me a dummy unicast v6 ip?	
7/13/2006		6:59:40 PM		Yoo		husni, Abdul Awal 		why don't u just use ipv6 of dvrecv in ait?	
7/13/2006		7:00:11 PM		Abdul Awal 		husni, Yoo		in that case AIT will receive duplicate packets from both dvrelay	
7/13/2006		7:01:00 PM		Yoo		husni, Abdul Awal 		can you check ipv6 of imlsdds and use that one? 	
7/13/2006		7:01:06 PM		Yoo		husni, Abdul Awal 		send to itself is ok or not?	
7/13/2006		7:01:48 PM		Abdul Awal 		husni, Yoo		ok	
7/13/2006		7:01:52 PM		Abdul Awal 		husni, Yoo		I am installing now	
7/13/2006		7:01:56 PM		husni		Abdul Awal , Yoo		let's have a meeting -> yoo	
7/13/2006		7:01:59 PM		Yoo		husni, Abdul Awal 		ok	
7/13/2006		7:02:22 PM		Yoo		husni, Abdul Awal 		disconnect a moment	
7/13/2006		7:02:53 PM		Abdul Awal 		husni, Yoo		I am not in the sudo list in that pc	
7/13/2006		7:03:57 PM						Yoo has left the conversation.	
7/13/2006		7:10:03 PM		Abdul Awal 		husni		Husni, could you please turn of the vdo and point the camera to us?	
7/13/2006		7:10:20 PM		Abdul Awal 		husni		have some words for us as a instructor. :)	
7/13/2006		7:10:30 PM		husni		Abdul Awal 		i am not in that room	
7/13/2006		7:10:54 PM		Abdul Awal 		husni		ok.	
7/13/2006		7:10:55 PM						Yoo has been added to the conversation.	
7/13/2006		7:11:13 PM		Abdul Awal 		husni, Yoo		Hi Yoo, I cannot install dvrealy as I do not have sudo power	
7/13/2006		7:11:31 PM		Abdul Awal 		husni, Yoo		and I am now controlign the dvrelay	
7/13/2006		7:11:48 PM		Abdul Awal 		husni, Yoo		u can kill the dvrelay and run again to see the output of -L	
7/13/2006		7:13:13 PM		Abdul Awal 		husni, Yoo		now I am using -f 6 to see the quality	
7/13/2006		7:18:44 PM		Abdul Awal 		husni, Yoo		husni -- are u there? knchana here	
7/13/2006		7:19:10 PM		husni		Abdul Awal , Yoo		yes, in a different room having a meeting	
7/13/2006		7:19:22 PM		Abdul Awal 		husni, Yoo		seems like packet loss in JP side	
7/13/2006		7:19:36 PM		husni		Abdul Awal , Yoo		before dvrelay or after dvrelay?	
7/13/2006		7:19:40 PM		Abdul Awal 		husni, Yoo		frm dvsend to dvreay	
7/13/2006		7:20:00 PM		husni		Abdul Awal , Yoo		there are 3 switches between those machines	
7/13/2006		7:20:31 PM		husni		Abdul Awal , Yoo		i don't know where the packets get dropped	
7/13/2006		7:20:31 PM		Abdul Awal 		husni, Yoo		before is higerthan after	
7/13/2006		7:20:51 PM		Abdul Awal 		husni, Yoo		an we move your machine to be near dvrelay	
7/13/2006		7:21:16 PM		Abdul Awal 		husni, Yoo		else useless to keep going	
7/13/2006		7:21:54 PM		husni		Abdul Awal , Yoo		if that is the case, it's difficult for me to do it tonight	
7/13/2006		7:22:08 PM		Abdul Awal 		husni, Yoo		how to ee packet loss on ai3? 	
7/13/2006		7:23:20 PM		husni		Abdul Awal , Yoo		we need a dvrecv before the satellite router	
7/13/2006		7:24:32 PM		Abdul Awal 		husni, Yoo		yoo - how can we find out about packet loss on sat link?	
7/13/2006		7:26:27 PM		Abdul Awal 		husni, Yoo		canyou try to get id of other trafic on the satellite link for 10 mins?	
7/13/2006		7:27:00 PM		Abdul Awal 		husni, Yoo		are you there?	
7/13/2006		7:33:50 PM		husni		Abdul Awal , Yoo		other traffic?	
7/13/2006		7:35:08 PM		Abdul Awal 		husni, Yoo		on ai3 -- can we clear other traffic for a few minutes -- to make sure we cold improve on loass ratefrom dvrelay to dvreceive	
7/13/2006		7:36:12 PM		husni		Abdul Awal , Yoo		wait	
7/13/2006		7:36:16 PM		husni		Abdul Awal , Yoo		let me prepare	
7/13/2006		7:36:25 PM		Abdul Awal 		husni, Yoo		ok	
7/13/2006		7:42:50 PM		husni		Abdul Awal , Yoo		pls try	
7/13/2006		7:46:41 PM		Abdul Awal 		husni, Yoo		now there is no other traffic?	
7/13/2006		7:46:50 PM		husni		Abdul Awal , Yoo		limited to 1Mbps	
7/13/2006		7:47:01 PM		husni		Abdul Awal , Yoo		you have > 7.5Mbps	
7/13/2006		7:47:07 PM		Abdul Awal 		husni, Yoo		ic. we are using 5 frame/sec	
7/13/2006		7:47:15 PM		Abdul Awal 		husni, Yoo		let me try with less	
7/13/2006		7:47:58 PM		Abdul Awal 		husni, Yoo		now we are sending 3 f/sec, should utilize less than 6 mbps	
7/13/2006		7:48:08 PM		Abdul Awal 		husni, Yoo		but we are facing packet loss too	
7/13/2006		7:48:12 PM		Abdul Awal 		husni, Yoo		let me record	
7/13/2006		7:48:17 PM		Abdul Awal 		husni, Yoo		I will vdo	
7/13/2006		7:53:46 PM		husni		Abdul Awal , Yoo		what's the permissible packet loss?	
7/13/2006		7:54:45 PM		Abdul Awal 		husni, Yoo		less than 1% if no other traffic	
7/13/2006		7:55:20 PM		Abdul Awal 		husni, Yoo		Yoo did the experiement last week with iperf and usign 5 mbps rate	
7/13/2006		7:55:45 PM		Yoo		husni, Abdul Awal 		6 mbps rate	
7/13/2006		7:56:38 PM		Abdul Awal 		husni, Yoo		ok, with 6 mbps there should be less than 1% loss, but now we are seeing arround 20% packet loss with 3 f/s	
7/13/2006		7:57:28 PM		Abdul Awal 		husni, Yoo		can we assume that there are some packet loss before satellite link?	
7/13/2006		8:00:16 PM		husni		Abdul Awal , Yoo		i think there are no packet losses before satellite	
7/13/2006		8:00:39 PM		Abdul Awal 		husni, Yoo		in http://sfc-serv.ai3.net/UDLOUT/udlout.cgi, I see all the graphs are empty	
7/13/2006		8:01:47 PM		husni		Abdul Awal , Yoo		don't mind that graph	
7/13/2006		8:01:50 PM		husni		Abdul Awal , Yoo		it's for old feed	
7/13/2006		8:02:00 PM		Abdul Awal 		husni, Yoo		ok	
7/13/2006		8:06:56 PM		Abdul Awal 		husni, Yoo		Now we are also watching packet loss but less that before	
7/13/2006		8:07:33 PM		Abdul Awal 		husni, Yoo		now, you please go back to normal settings	
7/13/2006		8:09:43 PM		Abdul Awal 		husni, Yoo		please let us know when you reset to previous settings	
7/13/2006		8:14:37 PM		husni		Abdul Awal , Yoo		done	
7/13/2006		8:14:45 PM		husni		Abdul Awal , Yoo		the only difference is 	
7/13/2006		8:14:47 PM		husni		Abdul Awal , Yoo		now it is 1.5	
7/13/2006		8:14:51 PM		husni		Abdul Awal , Yoo		it was 1.0	
7/13/2006		8:15:40 PM		Abdul Awal 		husni, Yoo		is IPv4 multicast is enabled?	
7/13/2006		8:16:16 PM		husni		Abdul Awal , Yoo		not really	
7/13/2006		8:17:03 PM		Abdul Awal 		husni, Yoo		how can we get the packet loss statistics in UDL ? is there any way?	
7/13/2006		8:17:45 PM		Abdul Awal 		husni, Yoo		I would run one program of mine which runs in IPv4, my program can tell us the packet loss statistics in UDL.	
7/13/2006		8:19:00 PM		husni		Abdul Awal , Yoo		how do you measure packet loss in any link?	
7/13/2006		8:19:31 PM		Abdul Awal 		husni, Yoo		actually, I send packets from sfc-lmdds pc to AIT soi-server.	
7/13/2006		8:19:45 PM		Abdul Awal 		husni, Yoo		then I calculate how many was sent and how many was received	
7/13/2006		8:20:05 PM		Abdul Awal 		husni, Yoo		and based on that I calculate the packet loss in UDL.	
7/13/2006		8:20:21 PM		Abdul Awal 		husni, Yoo		for my program, not for the whole UDL.	
7/13/2006		8:21:45 PM		husni		Abdul Awal , Yoo		we have a problem with ipv4 multicast	
7/13/2006		8:22:20 PM		Abdul Awal 		husni, Yoo		Yoo, are you there?	
7/13/2006		8:25:02 PM		husni		Abdul Awal , Yoo		can't we use iperf?	
7/13/2006		8:25:06 PM		husni		Abdul Awal , Yoo		what's the difference?	
7/13/2006		8:25:15 PM		Abdul Awal 		husni, Yoo		yes I am tryign to run the Iperf now	
7/13/2006		8:25:40 PM		Abdul Awal 		husni, Yoo		if you can do for us, that is nice. Porf. Kanchana requested you.	
7/13/2006		8:25:50 PM		husni		Abdul Awal , Yoo		i am still in a meeting	
7/13/2006		8:25:58 PM		Abdul Awal 		husni, Yoo		oh ok.	
7/13/2006		8:26:05 PM		Abdul Awal 		husni, Yoo		I am trying .	
7/13/2006		8:47:52 PM		husni		Abdul Awal , Yoo		how's the iperf ?	
7/13/2006		8:48:44 PM		Abdul Awal 		husni, Yoo		I am little bit confused with iPerf. I am running iperf server in AIT, and client in sfc-lmdds.	
7/13/2006		8:49:05 PM		Abdul Awal 		husni, Yoo		In that case traffic flows from SFC to AIT through UDL , am I right?	
7/13/2006		8:49:26 PM		husni		Abdul Awal , Yoo		yes	
7/13/2006		8:49:57 PM		Abdul Awal 		husni, Yoo		if so, then I am seeing 70% packet loss with IPv4 UDP	
7/13/2006		8:50:30 PM		husni		Abdul Awal , Yoo		the current configuration is to prioritize ipv6 multicast	
7/13/2006		8:50:39 PM		husni		Abdul Awal , Yoo		so, please don't use ipv4	
7/13/2006		8:50:43 PM		Abdul Awal 		husni, Yoo		ok then I am running IPv6 multicast	
7/13/2006		8:55:51 PM		husni		Abdul Awal , Yoo		how's the result?	
7/13/2006		8:56:21 PM		Abdul Awal 		husni, Yoo		I run [awal@ait-soi 4M]$ /usr/local/bin/iperf -s -u -V -B ff38:20:2001:D30:101:1:1:2 in AIT	
7/13/2006		8:56:48 PM		Abdul Awal 		husni, Yoo		and > /usr/local/bin/iperf -c ff38:20:2001:D30:101:1:1:2 -V -u --ttl 10 -b 1m in sfc-lmdds	
7/13/2006		8:57:26 PM		husni		Abdul Awal , Yoo		and the result is>	
7/13/2006		8:57:28 PM		husni		Abdul Awal , Yoo		?	
7/13/2006		8:57:43 PM		Abdul Awal 		husni, Yoo		but the server is not sending any report	
7/13/2006		8:58:10 PM		Abdul Awal 		husni, Yoo		is the command ok?	
7/13/2006		8:58:34 PM		husni		Abdul Awal , Yoo		better to ask yoo for this	
7/13/2006		8:59:14 PM		Abdul Awal 		husni, Yoo		ok.	
7/13/2006		9:06:18 PM		Abdul Awal 		husni, Yoo		Are you limiting the other traffic to 1.5 mbps for this dvts test?	
7/13/2006		9:06:59 PM		husni		Abdul Awal , Yoo		yes	
7/13/2006		10:29:18 PM		husni		Abdul Awal 		how's the result?	
7/13/2006		10:29:23 PM		Abdul Awal 		husni		Hi	
7/13/2006		10:29:30 PM		Abdul Awal 		husni		We tested the IPv6 Unicast	
7/13/2006		10:29:40 PM		Abdul Awal 		husni		could not test with multicast v6	
7/13/2006		10:29:59 PM		husni		Abdul Awal 		why?	
7/13/2006		10:30:25 PM		Abdul Awal 		husni		for v6 unicast result, upto 6mbps rate , it gave < 2% loss rate	
7/13/2006		10:30:58 PM		Abdul Awal 		husni		for data rate > 6 mbps, loss rate is > 20%	
7/13/2006		10:31:25 PM		Abdul Awal 		husni		I could not get the result of v6 mcast in iPerf. I do not know why	
7/13/2006		10:31:33 PM		Abdul Awal 		husni		I will talk with yoo about this.	
7/13/2006		10:31:54 PM		Abdul Awal 		husni		i think I have used all the iperf parameters correctly but dont know why didnt work.	
7/13/2006		10:32:45 PM		Abdul Awal 		husni		server was listeing in a v6 mcast address, client was also sending data in same mcast address, but iperf server did not get any response from client	
7/13/2006		10:33:48 PM		husni		Abdul Awal 		ic	
7/13/2006		10:34:53 PM		Abdul Awal 		husni		the current settign in ai3 udl, does the v6 multicast and v6 unicast both includes?	
7/13/2006		10:35:02 PM		husni		Abdul Awal 		what do you mean?	
7/13/2006		10:36:22 PM		Abdul Awal 		husni		I mean the current configuration of traffic you set for AI3, it is for v6 malticast	
7/13/2006		10:36:30 PM		Abdul Awal 		husni		does it include v6 unicast	
7/13/2006		10:37:02 PM		husni		Abdul Awal 		yes, but v6 unicast is not that much	
7/13/2006		10:37:34 PM		Abdul Awal 		husni		our result with v6 unicast < 2% loss upto 6mbps rate	
7/13/2006		10:37:38 PM		Abdul Awal 		husni		this is good.	
7/13/2006		10:39:19 PM		husni		Abdul Awal 		okay	
7/13/2006		10:39:25 PM		husni		Abdul Awal 		so, what's next then?	
7/13/2006		10:40:09 PM		Abdul Awal 		husni		Now we will ask yoo to check the v6 mcast with iperf	
7/13/2006		10:40:16 PM		Abdul Awal 		husni		actually she alrady tried	
7/13/2006		10:40:52 PM		Abdul Awal 		husni		we are just guessing that the traffics are lost before satellite link	
7/13/2006		10:42:28 PM		husni		Abdul Awal 		ic	
7/13/2006		10:48:13 PM		husni		Abdul Awal 		so I just return the QoS setting now	
7/13/2006		10:48:50 PM		Abdul Awal 		husni		for general traffic, other RO site?	
7/13/2006		10:49:03 PM		husni		Abdul Awal 		for all UDL	
7/13/2006		10:49:32 PM		Abdul Awal 		husni		ok. sure	
7/13/2006		10:50:03 PM		husni		Abdul Awal 		when do you depart to singapore?
