Optimize network bandwidth usage in large multi-size corporate environments

SymptomsTo maintain a high protection level, you may notice an increase in bandwidth due to the increased number of updates released per day. Policy Manager Proxy (PMP) installations are especially affected as the additional strain on the likely slower network connection that exists between the remote site hosting the PMP installation(s) and the main corporate site with Policy Manager Server (PMS). The network bandwidth usage can be especially high when computers are turn on on Monday as the update packages accumulate over the weekend.
DiagnosisBy default, the Automatic Update Server (AUS) in PMS calculates byte-level differences for the last five update packages (per update channel). In the event where computers were turned off over the weekend, client machine has missed five updates, and PMS will then download a full update package (Aquarius Windows updates can be approximately 140MB in size). When this happens, network bandwidth usage can be excessively high.
SolutionWe recommend applying the suggested changes on all PMS and PMP systems and all of the F-Secure clients behind PMP installations. This may reduce the update size from 140MB to 10MB. The suggested solution consists of three different changes, outlined below:
1. Increase the number of byte-level difference files stored by the PMS
For Windows
To increase the number of byte-level differentials maintained by Automatic Update Server:
Open [F-Secure Installation Path]\FSAUS.PM\conf\server.cfg in Notepad.
Find the key num_old_versions_to_compare, change the value to 50, and save the file.
Restart Automatic Update Agent (AUA) and Automatic Update Server (AUS). In command prompt: net stop fsaua, net start fsaua, net stop fsms, net start fsms.
For Linux
To increase the number of byte-level differentials maintained by Automatic Update Server:
Open /etc/opt/f-secure/fsaus/conf/server.cfg.
Find the key num_old_versions_to_compare, change the value to 50, and save the file.
Restart Automatic Update Agent (AUA) and Automatic Update Server (AUS) daemons (root privileges required): #/etc/init.d/fspms restart
The overall disk space requirement for PMS increases. We estimate the disk consumption to increase by 10GB. Make sure the hard disk hosting the Policy Manager Server installation (Program files\F-Secure\Management Server 5\) has enough disk space.
2. Increase the cache size available on the PMP for storing files
For Windows
Note: Use the Advanced mode in Policy Manager Console (View >> Advanced mode) to edit the setting.
Go to F-Secure Policy Manager Proxy > Settings > Communication > Cache size.
The default setting is 500. Increase this to 5000 (5GB) and distribute new policies.
Verify the setting on all Policy Manager Proxy systems and adjust the settings, if needed. The setting specifies how much disk space is set aside for storing databases on the Policy Manager Proxy.
For Linux
As Policy Manager Proxy on Linux is not centrally managed, the change involves modifying a configuration file that exists on the Policy Manager Proxy system locally.
Open /etc/opt/f-secure/fspmp/conf/proxy.cfg.
Find the key max_cache_size, and change the value to 5000: max_cache_size=5000.
Restart the fspmp daemon (root privileges required): #/etc/init.d/fspmp restart
3. Adjust the F-Secure Anti-Virus client configuration using Policy Manager Console (PMC) to help prevent clients from immediately falling back to downloading updates directly from the PMS.
In case the client is unable to connect to the Policy Manager Proxy, for example due to high network traffic and multiple downloads taking place, the following setting dictates how soon the client attempts to connect directly to the Policy Manager Server to download updates.
In Policy Manager Console, go to F-secure Automatic Update Agent > Settings > Communications > Policy Manager Proxies > PMP Proxy fallback time.
Default value is zero which means fallback to PMS takes place immediately, in case where Policy Manager Proxy installation cannot be reached. To prevent this from happening, configure this setting to a higher value (suggest 7 hours).
These steps should ensure database updates are only downloaded via the PMP.

Measure the Network bandwidth usage

Hi,
For application server, is there any Oracle tool to be used to measure the Network bandwidth usage?

Hi，
The following policies are supported in Window 7
Computer Configuration | Administrative Templates | Network | Background Intelligent Transfer Services (BITS) |Set up a maintence schedule to limit the maximum network bandwidth used for BITS Background transfers
or Set up a work schedule to limit the maximum network bandwidth used for BITS Background transfers
see this link

What Is The Network Bandwidth Usage Report?

I'm looking at the "Network Bandwidth Usage" report and it's just a list of devices with no bandwidth numbers? Is it ordered by amount of usage and if so, why isn't the usage displayed in the report and how do I see the usage for a device?
This topic first appeared in the Spiceworks Community

Page 22 of this document will give you some numbers that will allow you to estimate the total data used for a meeting. Keep in mind these numbers are what Adobe saw as average consumption, yours may be higher or lower.

N/W Bandwidth usage

All,
I was wondering of there is any documentation around the typical network bandwidth usage by the BOE XI R2 application (InfoView/WebI)? As part of the deployment of some new servers here, before they can allocate us the appropriate bandwidth, the network team wants us to give them some numbers around what are the typical data transfer rates on the network pipe. For this, we have assessed the total number of concurrent users of the application, but there isn't really any way for us to gather the data usage rates.
Does anyone know if the PSO/PG/SC or another group has any information about this - where they may have run tests and gathered results fro typical data bandwidth usage rates when running WebI reports via InfoView?
I know this is a rather unusual request, but we don't have an option - the network team won't move until we have a good backing from the vendor (BOBJ/SAP) about the "recommended" numbers for this!
Any help will be greatly appreciated!
Cheers,
Sarang

Denis,
Thanks for the response! That was my first answer to them also, and something that I have already asked the team to take a look at on our side.
In the meanwhile, I wasn't sure if the PG or PSO runs any benchmark tests every now and then, from data gathered from the the most typical app usage by a group of clients. I remember seeing something in the past about load testing from the PG, but not sure if something like this exists for n/w b/w usage.
I think your idea still is the best starting point, but benchmark results (if any) would be a great help!

100 percent bandwidth usage

I have two 2 Cisco 2821-VK/9 routers between 2 offices. The connection between the 2 is a 2 Meg diginet line.
When ever I copy a file between the two sites that is more than 1 Gb in size, the bandwidth usage is 100 % and it takes a very long time to complete.
Could you please advice what I should do.
Regards
Cyril

Hi Cyril,
I'll assume since you're posting in the UC section that your question in some way relates to voice/video traffic on that link and perhaps not just to the length of time taken to copy large files.
you might want to consider implemented a QoS policy on your network if there isn't one already in place.
You can start with some light reading here.
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/5x/50nstrct.html#wp1043960
It won't make your 1Gb files copy faster but it can help stop them choking off your other network traffic.
regards,
Paul

Understand the bandwidth usage on production.

Hi all, i try to understand the bandwidth usage on production time on the network. I took one C3560G with all device are conected to 1000Mb/s.
I make: show int gi0/1
5 minute input rate 320000 bits/sec, 555 packets/sec
5 minute output rate 9787000 bits/sec, 821 packets/sec
The total is: 10.1 Mb/sec (on this port)
In all active port the summary is: 47 Mb/s (input rate+output rate in all ports)
So, i used 4,7% of the total of the bandwidth. And in cacti (by snmp) software i see one device transfer data with a maximun of 24Mb/s. Why don't use more bandwidth if is available?
Some can give me a hand to understand this?
Thanks!

So, the bandwidth is limited for the windows size. How i manualy set the RWIN? in a LAN is posible?
Yes, it's often possible. How depends on the host. Search the Internet for BDP and your host IOS, and you'll likely find how to adjust.
PS:
BTW, too large a RWIN can cause a sender to send too many packets at one time which can result in drops. Have you checked your transit interfaces for drops?
Ideally, RWIN should be sized for BDP; not smaller and not larger.

High bandwidth usage while inactive

Twice today I've glanced at Activity Monitor's Dock icon, which I have set to view Network Usage, and saw a large amount of data streaming continuously through my internet connection.
This morning when I noticed it for the first time, I poked around my system, and after not seeing any other programs (Safari, Software Update, etc.) being active, I tried quitting Messages Beta - and the bandwidth instantly dropped down to nothing. At that time, it was moving around 60KB/sec upstream, and probably around half that downstream according to Activity Monitor.
A few minutes ago this evening, I saw it happen again - my Activity Monitor was showing heavy continuous bandwidth usage. This time I simply set my status to 'Offline' in Messages Beta and once again it instantly dropped down to nothing. This time the bandwidth was closer to 160kb/sec upstream, and half that downstream! When I changed my status back to 'Available' a few seconds later, everything continued on normally, with almost no data usage.
I had no active chats going, never used video, screen or file sharing - so what in the world is Messages Beta doing with so much data streaming? I'm quite mystified, and wondering if anybody else has seen this happen....

The issue seemed to be local network traffic.

Determining actual DSL bandwidth usage

Hello All,
           I am seriously considering going to truly wireless (MiFi) internet after years of using DSL service. However, there's one thing I have no data on: my actual bandwidth usage month by month.
           Obviously I know I can't go back to day one and get this data, but I find it impossible to believe that it cannot be obtained relatively easily. There is an old thread from 2010 where someone implied that one could query the DSL modem or modem/router could be queried to get this data. I was not able to post a reply on that thread, and I presume that's because it's closed to new messages.
            Right now I have the latest D-Link router from Verizon and am able to log in to it without problems. But this particular router has more possible options on more web pages (or their equivalent) than I've ever seen before. Although I am a "tech geek" I have no idea where to look among the myriad options to seek out this data.
            If anyone has an answer as to how to query this router, or knows of a web resource that tells you how to do this "generically," I'm sure I can do so after a little noodling around.
            Thanks in advance for your assistance.
Brian

I'm not the most familiar with the D-Link routers Verizon hands out, but what you're looking to find is some information on the WAN or "Internet" end of the modem for how many bytes of traffic you have sent and received. This information may be for when the router was last rebooted or it may be from the last time your connection re-connedcted if it has dropped, so it isn't really accurate when it comes down to a breakdown of things. If you can get a byte count, it is easy to convert to Megabytes or Gigabytes from that point (Factorsof 10 in a general sense). By definition a Kilobyte is 1024 Bytes, but in some cases a factor of 10 is applied so a Kilobyte is 1000 Bytes. A Gigabyte can be 1024 or 1000 Kilobytes depending on how the data is being measured like previously mentioned.
So, 40,960 Bytes / 1024 = 40 Kilobytes / 1024 = 0.039 Gigabytes.
Considering how large (or small) the data plans tend to be on a Mi-Fi device, consider the type of network traffic you currently have and gauge it against future use. If you currently have gamers in the house, a Mi-Fi should already be off the table as a full blown replacement as cellular connections are poor quality connections for playing video games on. Not to mention, games and patches can consume the cap quickly if the gamer has a lot of games that they play. Also, if your home is Netflix or YouTube heavy, without turning down the video quality you'll find it's quite easy to run over a cap. On a Mi-Fi myself, I have to restrict my YouTube access since I am picky about low quality video, and force everything to HD. I can slip in a few videos on a Grandfathered 3GB plan with Verizon but if I watch some of the common, 20 minute videos I watch, that's a Gigabyte per video on average. My normal net usage would burn me through the cap in less than an hour.
Just some food for thought, but keep in mind Verizon will most likely be unable to provide any sort of data usage counter. You may need to use third party routers or software in order to determine your usage per month.

Bandwidth usage with homesharing

I have recently found my bandwidth being used while streaming from Macbook Pro to Apple TV whilst using Home Sharing. Watching a 1.2 GB movie streamed from iTunes to Apple TV uses 1.2 GB of bandwidth!
I have reset my Apple TV but the problem continues.
I have disconected the Bell modem from the internet and the problem goes away. The Macbook streams efficiently to the Apple TV using the home wireless network.
Has anyone encountered this problem? And, more importantly, can anyone suggest a solution.
Thanks for any help you may be able to provide.

Hi diesel vdub
I am definitely using the Computers icon of my Apple TV. I have factory reset the modem but the issue remains. As I mentioned before when the modem is on, but disconnected from the internet, movies and videos stream fine to the Apple TV with no significant bandwidth usage.

Video Stalls - Larger File Size

Just downloaded Battlestar Galactica season 2 and the video stalls at full screen. Do not have this problem with previous Battlestar Galactica shows and movies that I have downloaded in the past.
I notice the File Size and Total Bit Rate of the new shows are three times greater in size than the shows I've downloaded in the past.
Using the utility ativity monitor, I notice I'm maxing out my CPU when I go to full screen which I think is causing my video stall.
I also notice that now my previous TV show downloads don't fully fill my screen like that did before the new downloads.
I hope someone might know how I can get my TV shows back to working normal at full screen and why the new TV shows file sizes are larger than before.
Thanks for Your Help

Thanks for the reply. Shortly after I posted, I started to relize that Apple was offering better TV Show quality which results in larger file sizes. I also went to my Energy Saver section in System Prefrences and found my Optimize Energy Settings was set for Presentations. I changed it to Highest Performance which resolved the issue.

Batch export to network drive fails on large clips

SO I have dozens of clips to batch export in full quality uncoompressed format. THey come out anywhere from 1-10 gigs per file.
When I export to a desktop drive everything works great, when I do the same batch export to a network attached storage drive I have all the larger files failing on me.
Has enyone experienced this before and can you help?
Desktop drive works
Network drive works on smaller file sizes.
G5 Quad, G5 Dual, G4 PB Mac OS X (10.4)

ah yes, known but ignored issue no. 456282
files over 2 gigs will not transfer over network when transfer is initiated via FCP, either by export, media manager, or any other process.
doesn't matter if target drive is mac format or otherwise, it doesnt work.
doesn't help, but at least you know its not something you did or didn't do.
cheers

Need to get large file sizes down to downloadable sizes-how?

I am using Compressor 4 and have several professional videos I produced with Final Cut Studio in QuickTime/.MOV format using ProRes 442. They are all 720p and of course, all have large file sizes. I needed to convert them so they are compatible with iTunes as well as Apple devices (AppleTV, iPad/iPod/iPhone, etc). They also need to be downloadable in a reasonable time and I of course want to maintain a quality image. Several of the videos are about an hour long, some a little more.
I an unable to get most of these files to be small enough for practical download and still maintain an acceptable quality. For example:
I have one video (QuickTime rendered from FCPS) that runs 54 minutes. 1280x720, ProRess 422, Linear PCM with a Bit rate of 72.662. The best I seem to be able to get out of compressor is to use the setting options for "HD for Apple Devices (5 Mbs)" which gives me a file that's just over 2Gb. Not bad, and the quality is still very good, but the file size is just too big for people to download. I get reports of people getting estimates of 77 hours to download this one file.
I did try using the setting under Video Sharing Services / Large 540p Video Sharing just to see what it would give me, but it really wasn't that much smaller and the quality was noticeably degraded.
I'm confused as to what to do about this. I have downloaded things from iTunes before that are good quality, about an hour and their file sizes are simply bnot this big.
Can anyone give me some advice? Thank you. Grateful for anything you can offer.
MC

If you're not concerned with precise average bitrate, use h.264 codec, set bitrate to "automatic" and use the quality slider. Be sure to have "keyframes" on "automatic"; every 24 frames or so makes h.264 quite inefficient and is only useful for live-streaming, where you want people to be able to resynchronise as quickly as possible. Having multi-pass enabled might help, but I'm not sure what it does when using constant-quality encoding.
Do a test-encoding of a representative clip of maybe about rwo minutes or so, play with the quality slider and see how far down you can go and still be satisfied with the quality. Using "automatic" bitrate uses as many bits to encode each frame as is necessary to get the required quality, and file sizes will vary depending on the type of material. Complex textures and high motion will use more bits, still frames and slow pans will use very little.
A light chroma-channel denoising may help improve perceived quality, as may very light sharpening in case you scaled down the material.
If you're still not happy with the bitrate vs. quality tradeoff, try reducing the resolution, but generally you should get 720p down to around 2.5 to 3.0 Mbps with adequate quality.
On the other hand, If someone needs 77 hours to download 2 GB, they have another problem anyway. That sounds like a 56k modem connection. What's he doing trying to download HD content anyway?

WTR1900 Internet Bandwidth Usage Report

Hello,
I have many client devices connected to my WRT1900... When I click on the Internet Bandwidth Usage Report, the results have every device listed as 0.00 MB of internet traffic. Well, every device on my network access the Internet constantly.
What am I missing to have this report actual provide some information?

Hi @brudertl,
I also got confused with this before. I just tried to powercycle the modem, router and all the devices on the network. This might help.

Large email size problem-Help me

Hello Friend,
We have 4 system with sharing internet broadband connection through 8 pin connector.my problem is large email size is not outgoing through outlook express. (Outlook express 6)More then 50 kb is not going.In this main system was large size eamil attached file is easily going and ftp file also uploaded.In Other 3 system is not outgoing email and ftp upload also is not working.Please help me and give some solution very urgently.

I'm very sorry, I can't help you at all with your FTP problems. Likely, i'll not be able to help you with your other problem, either. I can't tell what software you're using, or even if SunJavaEnterprise Messaging Server is involved at all.
I suspect that you are having some kind of timeout/network problem. I have no idea what your "8 pin connector" means, nor what else you're doing. I'd be calling your ISP first, for their help.

MPLS Sizing - Enterprise Bandwidth Usage by Application

Hello Everyone,
In an effort to estimate bandwidth usage on an MPLS upgrade and rollout we have been tasked with determining what bandwidth is required without use of baseline measurements on live data.
Would anyone have a table or chart of applicaitons and their associated bandwidth requirements?
For example
SAP
Salesforce.com SAAS
desktop video conferencing
Email with attachments
etc
Thank you for your help,
Matthew

yeah... you bet, i considered all the options with access to the network.
Here is the scoop - Network is on 200 locations (MPLS), and I need to estimate for future applications.
I really really really wish for a chart that tells me BW per user per App...
dreaming?
