Multicast packets per second

Are there any pointers to multicast performance numbers on a cisco switch?

Hi,
For Layer 2 platforms, IGMP snooping is implemented in hardware, so forwarding performance is only limited by the overall performance of the switch. Unconstrained multicast are forwarded as broadcasts, so the same restriction applies.
2950 specs:
http://www.cisco.com/en/US/products/hw/switches/ps628/products_data_sheet09186a00801cfb64.html
Couldn't find any specs for the 3500Xl switches, as they are well past end of sale, but they'll operate the same, with the exception that they use CGMP rather than IGMP snooping.
For the 4000, i'll need to know which supervisor, and if you are talking about layer 2 multicast or multicast routing.
HTH,
Bobby

I've not been able to find anything beyond a bandwidth capacity rating, such as 500 Mbps upgradable to 1 Gbps for the 4431.
I did find http://www.cisco.com/c/dam/en/us/products/collateral/routers/4000-series-integrated-services-routers-isr/enterprise-routing-portfolio-poster.pdf?mdfid=283967372
The point of interest for the foregoing, is the performance listings for the 800 series routers. Assuming their bandwidth performances ratings are using a similar performance methodology for all the routers, we can look at whitepapers, like the attached, and presume the 4000 series bandwidths are a total aggregate for typical traffic with most typical "WAN" features enabled. I.e. presume 500/1,000 Mbps is maximum recommended aggregate bandwidth usage with typical "WAN" traffic and typical "WAN" features.
PS:
Documents like: http://www.cisco.com/web/partners/downloads/765/tools/quickreference/routerperformance.pdf can be very easily misunderstood when trying to predict real-world performance. I suspect Cisco's latest bandwidth recommendations are trying to provide an easy to understand values for sizing routers for typical usage.
The attachment shows how feature usage, and traffic content, impacts ISR performance, which is why the older document can so easily mislead.

WLCCP packets from 3 access points multicasting over 250 packets per second!?!

I've tried to discover why these three access points are sending WLCCP packets at this astonishing rate. I cannot determine when it started, however I believe it is causing many problems. I don't see any configuration items in the running config containing the keyword "wlccp". such as:
AP>(config)# wlccp ?
ap                                  Enable WLCCP AP
authentication-server   Authentication Server
wds                               Enable Wireless Domain Service Manager
wnm                              Configure Wireless Network Manager
Is it implicitly ON? Do I need to do "no wlccp ap" to turn it off.
I desperately need to make this stop?
Anybody have or have seen this phenomenon?

I have stopped the problem by putting tight multicast and broadcast storm control on every switch where an access point ingresses. That cleared up my wireless congestion. But the problem persists. The source MAC of the WLCCP packets are actually specific clients that are attached across the wireless via a work-group bridge. These are IP cameras and Network Video Recorders... why this? Hmmm.... no one knows....

How to set the number of packets to be send per second to the serial port in labview

hi.
i have to send data to serial port such that each packet of data should be send at a rate of 4 packets per second?? how can it be done??
thanks and regards
Solved!
Go to Solution.

What defines a packet?
You just need to have a while loop that has a wait timer in it of 250 milliseconds surrounding your VISA write function.

How can I read out the total connections per second?
Does the command

Or is this concerning the total packets per second?

How to see the number of events per second received by MARS

Hi,
I have a MARS installed in a client for demonstration porpuse. Is there a way for me to see how many events per second has the MARS received?
Like in the access-list's logs when even if it can not log due the rate limit it says "missed 20 packets due rate limit".
So maybe the MARS can not process all the events, but it can say how many events it received per second in avarege.

System.log fills up with bad packets errors (Multicast packet - CRC error)

Hello,
I've been trying to Google my problem but found no answers; hopefully someone can help me?
Whenever I'm online, my System.logs fills up (every second, and sometimes, multiple times each second) with the following message :
19/12/07 12:51:01 PM kernel AppleYukon2 - bad packet received. length: 60, packet status bits: Multicast packet, CRC error
19/12/07 12:51:01 PM kernel AppleYukon2 - bad packet received. length: 60, packet status bits: Multicast packet, CRC error
My DSL modem is connect directly into my iMac. It's a Speedstream 5360). I never have any problems connecting to the Internet and the speed I get is fine. When I configured my Network settings, I only added my PPPoE Service name username and âssword - everything else was automatically added (Ethernet configuration).
Is there anything I should change in the Advanced Settings?
The System.log causes me problem because it often causes the application Console to crash when I try to view it.

I should add that this problem didn't exist when I was using Tiger.
Also, when I called Apple Tech Support, I was simply told "just don't play with the Console".

Horrible video skip / lag problem - once per second in all apps!

I built a new system last month (my first AMD) and I am having a really aggravating problem. In all games and all video playback I get an annoying skip once per second, every second. It affects sound during gameplay but not during movie or mp3 playback. It even happens with the visualization mode in Windows Media Player.
My system is as follows: MSI K8N Neo4-F, A64 3200+ venice core, MSI 6800GT 256MB PCI-E, two sticks of Corsair valueselect DDR400 512MB each, 500 watt PS, 160GB 7200 SATA HDD. Most recent NVIDIA drivers for everything. WinXP Pro with SP2 and all updates, DX9C. Nothing overclocked, all settings standard.
I have tried the following solutions:
1) BIOS upgrades, started with 1.4, installed 1.5, MSI tech support gave me 1.6b2 and I installed that. No luck with any of them.
2) Memory, installed per MSI directions, but I've tried all legal combinations, including one stick at a time. No change.
3) full format and reinstall of WinXP. No luck.
4) Switching between WinXP IDE drivers and NVidia drivers, with and without RAID drivers, No luck.
5) Removal of 6800GT PCI-E card and replacing with Ancient 8MB PCI Permedia2 video card. Problem still persists.
6) Disable onboard sound and LAN. No luck.
7) Running Fedora core 4 on second partition. Installed Nvidia video drivers, tried some games. THIS WORKS! No hitch, no skip, no nothing. Framerates are noticably slower but very stable. In WinXP I saw framerates bounce all over the place, from 230 FPS down to about 70 with one game. That same game on Linux ran smoothly at about 166 FPS with only occasional slight drops. The big FPS drops in Windows usually came right after one of the skips but didn't occure after every skip.
Right now I'm stumped. Linux uses totally different drivers for sound, LAN and SATA support. Some of those drivers don't fully use the Nforce4 chipset's features, maybe that's part of the difference.

Thanks TireSmoke:
I had found that sticky, but I took your advice and went thorugh it in detail last night. Lots of great info, fixes tweaks and tools, sadly none of them fixed my problem. The lag problem most people are reporting is not really like the wierd problem I am having. I have tried the recoommended fixes with ablsolutely no change in my system's behavior.
I am beginning to suspect a faulty motherboard component.
Russ_XP:
I think you are correct about fast writes. I googled the heck out of that last night and couldn't find any reference to enabling or disabling fast writes on PCI-E.
The drive is SATA-1. The Neo4-F is not SATA-2 enabled (there is a hack for it though). From memory I think it's a Western Digital WD1600-something, 7200 RPM dirve. I've tried it on both SATA buses and tried disabling the unused bus in BIOS.
I'm pretty sure I can dig up an old PATA drive somewhere and give that a try.
Gpalmer:
True enough, and I don't have these problems under Fedora. Sadly this is a cross-platform game development box, I need both XP and Fedora working.
Black_God:
Nope, this is a clean install. Although I wonder, could any of the built in XP update and security tools be causing this? I have disabled Windows firewall and virus protection monitoring.

Downloads per Second slower than normal

Hi, i've moved from profile ADSL MAX to ADSL 2+ however my downloads per second are average around 2-400kbs a sec, my download speed is just over 7mb and my downloads have been around 850kbs a sec.
Any reason to why this is?
I don't do much heavy downloads, most of my connection is used for either gaming or downloading some the app or playstation and its really slow at downloading anything.

Acquire, display, and write data at 50 samples per second

I have a vi running on a PXI which samples data using two 4220's (all 4 channels) and one 6031 (only 6channels). I am acquiring data at 100 samples per second, but only need to write the data out at 50 samples per second. The data needs to be displayed at a minimum of 10samples per second. The problem is that the VI can not get 50samples per second writen to the file, it writes about 20 to 30samples per second.
I dont know if the issue is displaying the data which is holding up the writing at 50samples per second or if it is something else in the VI. I have moved the writing of the data to the outside of the while loop, but this did not help enough to reach 50samples/sec.
Is it better to change the waveform data types to dynamic waveforms? Would this increase speed of operations?

Galen,
Looking at your vi, I would recommend writing to your file in a different way. The function you are using is actually opening, writing, and then closing the file every time you call it. This greatly increases the amount of resources being used. Take a look at the Cont Acq to Spreadsheet File.vi example and note that the file is only being opened and closed once. The data is being written to the file during execution of the program, and then closed when the app is done running. The example is done in traditional DAQ but you should be able to do something similar with DAQmx. Try this and let me know if it helps.

How many of these objects should I be able to insert per second?

I'm inserting these objects using default (not POF) serialization with putAll(myMap). I receive about 4000 new quotes per second to put in the cache. I try coalescing them to various degrees but my other apps are still slowing down when these inserts are taking place. The applications are listening to the cache where these inserts are going using CQCs. The apps may also be doing get()s on the cache. What is the ideal size for the putAll? If I chop up myMap into batches of 100 or 200 objects then it increases the responsiveness of other apps but slows down the overall time to complete the putAll. Maybe I need a different cache topology? Currently I have 3 storage enabled cluster nodes and 3 proxy nodes. The quotes go to a distributed-scheme cache. I have tried both having the quote inserting app use Extend and becoming a TCMP cluster member. Similar issues either way.
Thanks,
Andrew

Well, firstly, I surprised you are using "float" objects in a financial object, but that's a different debate... :)
Second, why aren't you using pof? Much more compact from my testing; better performance too.
I've inserted similar objects (but with BigDecimal for the numeric types) and seen insert rates in the 30-40,000 / second (single machine, one node). Obviously you take a whack when you start the second node (backup's being maintained, plus that node is probably on a separate server, so you are introducing network latency.) Still, I would have thought 10-20,000/second would be easily doable.
What are the thread counts on the service's you are using?; I've found this to be quite a choke point on high-throughput caches. What stats are you getting back from JMX for the Coherence components?; what stats from the server (CPU, Memory, swap, etc)?; What spec of machines are you using? Which JVM are you using? How is the JVM configured? What's are the GC times looking like? Are you CQC queries using indexes? Are your get()'s using indexes, or just using keys? Have you instrumented your own code to get some stats from it? Are you doing excessive logging? So many variables here... Very difficult to say what the problem is with so little info./insight into your system.
Also, maybe look at using a multi-threaded "feeder" client program for your trades. That's what I do (as well as upping the thread-count on the cache service thread) and it seems to run fine (with smaller batch sizes per thread, say 50.) We "push" as well as fully "process" trades (into Positions) at a rate of about 7-10,000 / sec on a 4 server set-up (two cache storage nodes / server; two proxies / server.) Machines are dual socket, quad-core 3GHz Xeons. The clients use CQC and get()'s, similar to your set-up.

i download newest oracle jdbc jar file from oracle site
http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/htdocs/jdbc_10201.html
is this jar file JDBC 3.0 driver ?
is there any hibernate performance configuration?
is it any more performance tuning into JBoss or EJB with entity beans?
can anybody help me ? or is there any doc which can help me ?

What makes you think that your database, just the database (with the box that it is on) can handle that rate?
What makes you think that your network can handle that?
While this is going on is this the ONLY traffic that will be on the network?

Newbie trying to understand the frame/fields per second concept on video

Do video camera shutter speeds (1/60sec) reflect an interlaced field or a full frame comprised of two interlaced fields per part of a second.
I suspect that a shutter setting of 1/60sec means it's not a full frame of video but is just an odd or even lined interlace field. Meaning that if I want to shoot 30fps I need to keep my shutter setting on 1/60sec.
But if that's really the case, then what am I exactly shooting per second if actual NTSC frame rate is 29.97fps? I mean, the first 2p frames can easily be divided into two fields each, but what about the remaining .97frame. How can you divide that into two fields of interlaced video lines?
Forgive my ignorance but books have a bad habit of not answering back when you don't understand something they say.
iMac Intel Duo-Core; Intel Mac mini single-core Mac OS X (10.4.6)
iMac Intel Duo-Core; Intel Mac mini single-core Mac OS X (10.4.6)

The shutter speed is not relevant. I can be either field based or progressive. The frame rate is not dependent on the shutter speed.

Calculating Frames Per Second Accurately

I tried searching the forums for suggestions or code used to calculate FPS accurately... But was ultimately unsuccessful.
I think I have a pretty basic understanding of how it works... but I'm still left wondering if there's a better... or correct way of attacking the problem.
What I started out doing is taken a pre-cycle time sample using System's currentTimeMillis method, followed by the main parts I'm executing in my program and then took a second time sample. I subtracted the post-cycle from the pre-cycle to get the time... and it occurred to me that the currentTimeMillis is not exactly reliable. As it says in the API, "For example, many operating systems measure time in units of tens of milliseconds," when discussing that method.
I then noticed the nanoTime method and decided to use that.
It quite honestly seems to work perfectly for what I'm trying to accomplish.
I pretty much used the same steps as before.
But now my problem is that I want to limit the amount of frames per second to 60.
I decided that I should try using the Thread class's sleep(long millis, int nanos) method.
It seemed like it would work... but to my dismay, it did not.
The milliseconds, for the most part, were correctly timed... but still not always. The nanoseconds even less so... but I knew that the nanoseconds would be less reliable-I decided to use microseconds. Using microseconds doesn't even work that well.
So I wondered if there was an even better way... maybe a more 'manual' approach to fixing my problem.
I would greatly appreciate any input/knowledge on the matter.

its quite simple. Windows has an API call that can set the timer precision (its all based on some interrupt interval - I forgot the precise details). This precision is system wide, so if one application does it it is immediately active for all other applications running at that time. Applications can only lower it, so if you set it to 1ms then some other application cannot force it to 5ms for example.
Now here comes JVM bug number two.
As said the interval differs per system - sometimes it is 10ms, sometimes it is 15ms. The JVM wrongfully assumes it is always 10ms however. Do a test: try to sleep for some time that is a multiple of 10 (without the long running thread hack active); you'll find that the precision still sucks. That is because in this specific case the JVM does NOT change the system wide timing precision. But if you sleep for any number of milliseconds that is not a multiple of 10 it will actually temporarily set the precision to 1ms.
So the rule is: as long as one thread goes to sleep the precision is set to 1ms. When the last sleeping thread wakes up, it is reset to what it was. Then it also doesn't matter for what amount of time you make your real thread sleep as the long sleeping thread will not be sleeping for an amount that is a multiple of 10, thus forcing the precision to 1ms.
Now say that you don't do the long sleeping thread hack and you make your own thread sleep for say 9ms, switching to 1ms precision temporarily. This behavior makes it so that sampling the passed time (before and after sleeping) can be imprecise; you'll find that most of the time you'll get sampling that matches the number of milliseconds you slept and sometimes it jumps to 10/15ms depending on the granularity of your system. This is a concurrency problem; sometimes the precision is reset before you get a chance to sample the current time.
So to recap to give 100% accuracy with System.currentTimeInMillis(), you need to keep a thread sleeping at all time so the precision stays at 1ms.
And then finally we come to bug #3, which is a problem in Windows itself: rapidly changing the precision (which happens when you make a single thread sleep for short intervals) can screw with the system clock. I don't know if this problem still exists in later iterations of Windows, but it is again a reason to do the long sleeping thread hack. Because this is a known issue I still call this a bug in the JVM because of the way they implemented the precision timer activation, which can trigger the problem in Windows. The command line switch mentioned in the above bug report SHOULD have fixed that... but you know, facepalm bug #4.
But at the end of the day: even if at least 4 bugs can be named regarding precise timing in Java under Windows, the root of all evil is still the way timing is implemented in Windows itself making life too difficult for the poor JVM devs. What were the MS devs thinking at the time?

Final Cut Pro X Image Sequence Export missing frames per second option?

I am using the trial version of Final Cut Pro X. I can export an image sequence but it will only allow me to do so at 30 frames per second -every single frame!
So a 10 min movie takes half an hour to export 20,000+ frames that no one on earth has time to look thru.
In my old Final Cut Express I was able to choose 1 or 2 frames per second, which was just right.
What am I missing?
Do I need to buy Quicktime Pro or Compressor to allow me to export image sequences without exporting every frame?
Why would Apple even have an image sequence export if it only allows you to export every frame, or it that only in the trial version?
Thank you

I found a free option for you, if you don't already have Compressor 4.
In FCPX create your movie. Then SHARE as a Master File.
Get MPEG Streamclip, which is a free app available here.
http://www.squared5.com/svideo/mpeg-streamclip-mac.html
Drag your Master File into MPEG Streamclip.
In MPEG Streamclip, select FILE/EXPORT TO OTHER FORMATS.
In FORMAT: choose IMAGE SEQUENCE
In OPTIONS, choose your frame rate.
