Re: [WISPA] Suggestions for Mikrotik Bandwidth Management
This really comes down to preference and budget . I would agree that the 532 (non production as well) is a small board, however, starting up, 50-100 customers, this box will work. Its an industrial board that has proven itself quite capable. It really comes down to the amount of traffic etc. I have customers running a 532 board with 8 meg connections, with over 100 queues on it. It was doing NAT as well. This board never went about 50-60% . If that will handle your traffic, then great, but keep in mind, when you have 200 customers and moving 20 meg of traffic, it might not be enough! And most liekly will not be enough! I love how people want to use OLD servers, and old PCs as Mikrotiks. Ya, cheap cheap, fun fun, but they already have years of use on them! Just makes me wonder about some people! An example was a customer of ours, the owner starting complaining about Mikrotik how unstable it was.Start taking to him a bit, and he told me what kind of PC it was on. After a bit more talking i asked where the PC was from. He said when his windows 98 desktop was running too slowly, he decided to put another NIC it in and bingo, instant Mikrotik. But it was always failing due to power supply, hard drive etc. Of course, they also placed in the $15 power supplies back into it! Regardless on what you use, industrial hardware is the way to go! The 433AHs are very capable as well, much faster than the 532s, as well as the 1000 board. -- * Dennis Burgess, CCNA, A+, Mikrotik Certified Trainer Link Technologies, Inc -- Mikrotik WISP Support Services* 314-735-0270 http://www.linktechs.net http://www.linktechs.net/ */ Link Technologies, Inc is offering LIVE Mikrotik On-Line Training http://www.linktechs.net/onlinetraining.asp/* Tom DeReggi wrote: I'm not against Mikrotik Software as a core router.

We don't use anything less than a Quad Proc now a days, but then again, we need to support multi port GB. But even at low speeds, processor headroom is important.

Re: [WISPA] Alvarion VL issue
What firmware are you running? the 5.0.18 is supposed to handle noise better. I have been told to turn off automatic noise immunity on our VL. In our case it did help some. Have you run a Spectrum Analysis with the AU? find the quietest channel. Run a real SA, check h-pol too. Ultimately we switched to H-pol on our VL, way less noise.

[WISPA] Dragonwave antenna pattern for RM
Does anyone have a Radio Mobile antenna pattern for the Dragonwave Horizon Compact? Is there a better tool/method for figuring out if the 6+Ghz licensed freqs are appropriate for a link? I could be barking up the wrong tree with this... Are the higher freq licensed links appropriate for ~15-25 mile links? At the moment I'm using PTP600s and AN-50es to do the job but I can't get the speed I'd like because of noise floor. WISPA Wants You!

Re: [WISPA] Alvarion VL issue
I am running 4.0.27 on hardware revision A (it's been in the air a while now. I'm on the cleanest channel available, I can't switch to H-pol, mainly, just a lot of work to switch out 50 some users. Also we use H-pol mainely for our point-to-point gear. The funny thing is I have another 5.8 sector at the same site (VL) that does not have this problem and the site surveys just as much noise if not more I have tried the new 5.0.18 firmware on other sites and did not see any difference on hardware B or older, so I have not bothered to change those sites out yet. -Cameron -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ryan Langseth Sent: Thursday, July 10, 2008 11:19 AM To: WISPA General List Subject: Re: [WISPA] Alvarion VL issue What firmware are you running? the 5.0.18 is supposed to handle noise better.

Re: [WISPA] Suggestions for Mikrotik Bandwidth Management
Dennis, I do not disagree with your comments, on the capabilty of the product. My point was headroom. Of course it never goes over 50-60% utilization under the typical course of the week. But, I recommend that you watch it, next time they have a DOS attack. Regardless of whether you have less than 8mb transit and 50 subs or not is irrelevent. Its still painful to a WISP operator when the phone starts ringing off the hook with 50 people having troubles all at once. Been there, done that. My arguement was not agaisnt MT532, its a great product. More of a suggestion that a WISP is better off doing their best to make the budget, to add the headroom, that may save them tons of headaches and losses in the future. If only one sub gets pissed off and cancels over the coarse of the year, thats a $600 loss per year (at $50/month). One of our general rule of thumbs are... Always have significantly more processing power at the core than at the CPE/AP, so a customer can't take down your core. If your APs are 532s, it would make since for your Cores to be faster. I agree that my opinion may not be relevent based on the defination of core. There are many cases where a WISP has put up a 532, with several cards/sectors run off it, and then did the management of that via the same 532, and performs just fine, for their expectations. But that is not my definition of a core.

I would agree that the 532 (non production as well) is a small board, however, starting up, 50-100 customers, this box will work. Its an industrial board that has proven itself quite capable. It really comes down to the amount of traffic etc. I have customers running a 532 board with 8 meg connections, with over 100 queues on it. It was doing NAT as well. This board never went about 50-60% . If that will handle your traffic, then great, but keep in mind, when you have 200 customers and moving 20 meg of traffic, it might not be enough! And most liekly will not be enough! I love how people want to use OLD servers, and old PCs as Mikrotiks. Ya, cheap cheap, fun fun, but they already have years of use on them! Just makes me wonder about some people! An example was a customer of ours, the owner starting complaining about Mikrotik how unstable it was.Start taking to him a bit, and he told me what kind of PC it was on. After a bit more talking i asked where the PC was from. He said when his windows 98 desktop was running too slowly, he decided to put another NIC it in and bingo, instant Mikrotik. But it was always failing due to power supply, hard drive etc. Of course, they also placed in the $15 power supplies back into it! Regardless on what you use, industrial hardware is the way to go! The 433AHs are very capable as well, much faster than the 532s, as well as the 1000 board. -- * Dennis Burgess, CCNA, A+, Mikrotik Certified Trainer Link Technologies, Inc -- Mikrotik WISP Support Services* 314-735-0270 http://www.linktechs.net http://www.linktechs.net/ */ Link Technologies, Inc is offering LIVE Mikrotik On-Line Training http://www.linktechs.net/onlinetraining.asp/* Tom DeReggi wrote: I'm not against Mikrotik Software as a core router. I am however against a MT532 as a core router. A MT532 is fine as an AP or SU, that manages the subs on it, but for the core of a WISP, one needs more headroom. We don't use anything less than a Quad Proc now a days, but then again, we need to support multi port GB. But even at low speeds, processor headroom is important. Its important to have the headroom when you need it. It cost so little, for the extra processing power. There becomes huge differences in throughput based on packet size. When things get ugly are when you get a DOS attack that has either small packets 64bytes, or doesn't wait for acks to keep sending. Its also important to have enough processing for initiating testing routines, from the device. Or to handle logging, during diagnostic periods. There may very well be performance benefits of non-intel SBCs that handle interupts differently than x86, but still don't trust your core on a $150 SBC. There is to much revenue at risk. My understandign is MT now has some faster proc rack systems such as their 1000series? Maybe those are better options? Just my opinion.

Re: [WISPA] Any thoughts on a decent cache server
Patrick Nix Jr. wrote: In another attempt to light the bandwidth load we are going to setup a cache server. Any thoughts or suggestions on which one to use? I know this is the popular answer to everything on this list, but Mikrotik RouterOS has a decent, and dead-simple to use, proxy/cache package. The tricky part is probably finding the right place in your network to put it, and configuring firewall rules (so that Web traffic gets sent to the proxy/cache server), and even those aren't too difficult. At least the old one was pretty good - my experience with it was probably four years ago, but at the time it worked well. Between then and now, I believe Mikrotik has written their own (previously it was just the Squid open-source package, with their pretty interface on top). If you're comfortable with Linux, you can do it yourself, but the time you'll save is easily worth the low one-time cost of a RouterOS software license. Whatever you use, make sure you know how to handle exceptions. Some Web sites just don't play well with being proxied. (One of our customers is a dealer for a major auto maker, and the proxy/cache system basically killed their whole business, as the stuff in Detroit just flat refused to function.) You'll want an easy way to test this sort of thing at your desktop, to try to reproduce weird customer calls - and there will be some doozies. David Smith MVN.net WISPA Wants You!

Re: [WISPA] Dragonwave antenna pattern for RM
A couple notes... Because this is a Dragonwave thread, I'd recommend that you contact CharlesWu at cticonnect.com, I've been very pleased with his assistance in the past on Licensed. As for 11ghz dish size... The requirements are not size, it is gain characteristics of the dish. In most cases only a 4 ft dish demonstrated those characteristics. There is a 2.5ft dish on the market that DOES meet the requirements to be equivellent of a typical 4ft dish. If you need this 2.5ft dish, it will also effect your selection of gear, as some manufactyurers require use of a specific dish, based on the mounting and waveguide methods to be compatible. Take note that it is now legal to use smaller dishes, based on recent lobbying and FCC decission, but it is on a secondary basis that gives priority to the users of larger 4ft dishes. If you deploy smaller than the 2.5ft full spec'd dish, you should fully inform your self with exactly what that means, as far as rights you have under the license. With that said, we have been very pleased with our Trango 18Ghz Licensed gear. They are shipping 11Ghz stuff now also, and definately worth a look, if you have not yet made a purchasing decission.

Re: [WISPA] Dragonwave antenna pattern for RM
Generally speaking, when the FCC specifies antennas they are more interested in the pattern than the gain. Specifically, they have a beamwidth and sidelobe suppression mask that they insist upon. This is always true with satellite uplink dishes. Not totally familiar with the point to point fixed microwave requirements but I would suspect this to be the case there as well. For parabolic reflectors, gain=directivity*efficiency or directivity (beamwidth) = gain/efficiency. Most parabolics are about 50-60% efficient. So you can treat that as a constant. - Original Message - From: Tom DeReggi [EMAIL PROTECTED] To: WISPA General List wireless@wispa.org Sent: Thursday, July 10, 2008 12:29 PM Subject: Re: [WISPA] Dragonwave antenna pattern for RM A couple notes...

Re: [WISPA] Dragonwave antenna pattern for RM
Thanks for pointing that out. In my mind that was what I was attempting to say. I guess I failed to take it to completion. I was trying to make the point that gain ~~ size~~ beamwidth but only in the broad general case. The FCC is not really caring about gain or size(in these cases); but since they all three are usually proportional many workers in the field use size as the rule of thumb. A very well designed high performance parabolic reflector can have the same sidelobe characteristics as a larger reflector. - Original Message - From: Tom DeReggi [EMAIL PROTECTED] To: WISPA General List wireless@wispa.org Sent: Thursday, July 10, 2008 12:48 PM Subject: Re: [WISPA] Dragonwave antenna pattern for RM Chuck, Yes, that is right, it is the radiation characteristics that are specified, that must be met.

Re: [WISPA] Any thoughts on a decent cache server
Not IMHO, You can just bypass the caching server for sites that give you trouble. I've had to by pass 3 or 4 so far. We only cache HTTP. One of our towers average bandwidth to the internet dropped from around 5Mbps to around 3Mbps and after 3 weeks up it has cached over 55GB. Mikrotik also lets you bypass bandwidth queues for cached data so subs get the pages fast. We use a Powerouter 732 as the core router at this tower and have a 250GB drive in it. We first tried dropping a cheap box plugged into a 532a but the CPU was hammered by the packets coming in one one interface, going out to the cache box, and coming back in the router, then going back out the interface connected to the radios. Caching with the router itself has really helped a lot.

Re: [WISPA] Any thoughts on a decent cache server
I'd like to mention there could be other good benefits for caching. For example, It can be beneficial to cache sites that are geographically far away. The farther a site is away the more latency it has, and there fore the speed per session diminishes, based on the formula like window size = bandwidth * delay. . TCP throughput vs. window size for RTT=70ms Window Size Theoretical max throughput Realistic throughput 8KB 0.9Mb/s 0.8Mb/s 16KB 1.9Mb/s 1.8Mb/s 32KB 3.7Mb/s 2-3.5Mb/s 64KB 7.5Mb/s 3-7Mb/s 128KB 15.0Mb/s 6-14Mb/s 256KB 30.0Mb/s 10-25Mb/s 512KB 59.9Mb/s 20-40Mb/s 1MB 119.8Mb/s 30-60Mb/s 2MB 239.7Mb/s 60-100Mb/s What often occurs is that Window Size is fixed at the customer PC. So even if someone has a 100mbps connection, and can test 100mbps to their server across town 5 ms away, there speed is still severally limited to far away high latency sites. Many PCs by default, don't enable window sizes above 64k. (Although most newer XP/VISTA machines are now comming Registry optimized for automatic tuning of larger windows szies, so this isn;t a problem.) So its not just about cost of long haul bandwdith, but also desire to deliver full speed to the consumer. By caching data locally, it enables the customer to access it at the full broadband connection speed. But my point being, customers can get a much better perception of performance if the most common files to download were cached locally for retrieval. What I'd be interested in learning more on is how to setup a caching server to selectively select what to cache based on latency to the content, or most common data, apposed to just caching everything. In otherwords, how to optimize the chance that the benefit of caching will outweigh the chances of getting troubles from caching.

I want to cache MS updates, youtube and expecially MSN and other high content sites that otherwise suck to use. marlon - Original Message - From: Patrick Nix Jr. [EMAIL PROTECTED] To: WISPA General List wireless@wispa.org Sent: Thursday, July 10, 2008 11:53 AM Subject: Re: [WISPA] Any thoughts on a decent cache server So is it safer/better to avoid caching servers altogether? __ Patrick Nix, Jr., csweb.net (918) 235-0414 http://www.csweb.net E-Mail: [EMAIL PROTECTED] ATTENTION: This e-mail may contain information that is confidential in nature.

Any thoughts or suggestions on which one to use? I know this is the popular answer to everything on this list, but Mikrotik RouterOS has a decent, and dead-simple to use, proxy/cache package. The tricky part is probably finding the right place in your network to put it, and configuring firewall rules (so that Web traffic gets sent to the proxy/cache server), and even those aren't too difficult. At least the old one was pretty good - my experience with it was probably four years ago, but at the time it worked well. Between then and now, I believe Mikrotik has written their own (previously it was just the Squid open-source package, with their pretty interface on top). If you're comfortable with Linux, you can do it yourself, but the time you'll save is easily worth the low one-time cost of a RouterOS software license. Whatever you use, make sure you know how to handle exceptions. Some Web sites just don't play well with being proxied. (One of our customers is a dealer for a major auto maker, and the proxy/cache system basically killed their whole business, as the stuff in Detroit just flat refused to function.) You'll want an easy way to test this sort of thing at your desktop, to try to reproduce weird customer calls - and there will be some doozies. David Smith MVN.net WISPA Wants You!

Re: [WISPA] Any thoughts on a decent cache server
I totally disagree with that David. A cache server will often make yahoo and other common sites load in MUCH less time.

Re: [WISPA] Any thoughts on a decent cache server
Hi, Back when we tried the cache server thing (5 years ago), it turned into more work than it was worth. We were getting 2-3 calls per day from people that certain web pages were broken and not loading correctly, etc. The real kicker was when UPS shut down our cache server's IP address because they thought we were doing "too many shipping lookups from the same IP address". Turns out one of our bigger customers was the main distributor for DISH Network and their automated system did a lookup on UPS's website whenever anyone was tracking a shipment. In the end, they canceled service ($500/month) because of this. Bandwidth is cheap now-a-days, even in Idaho (where the closest POP is 200+ miles). A cache server is just going to add headaches, support calls, and one more server(s) to maintain. Travis Microserv Marlon K.

Re: [WISPA] Any thoughts on a decent cache server
Tom, You can find all kinds of information if you do searches on squid. It's a very popular caching system that runs on *nix. The amount of RAM is directly related to the size of the disk cache. When we had servers 5 years ago (two of them in parallel) they were the fastest processors you could buy, with SCSI disk arrays in each one and I think 2GB of RAM each. I would guess in today's world you would be looking at 8GB or 16GB of RAM and very large disk arrays (6 disks x 500GB maybe). The other thing to consider is you now have another point of failure in your network. If a disk starts acting strange or the machine does a core dump, whatever you have re-directing traffic to the box may take 5 seconds to realize it's down and not send traffic to it. If you put it directly in-line with your traffic flow, you will have a complete failure of all internet services to your customers. :( Travis Microserv Tom DeReggi wrote: Any stats, on how much RAM is a good amount to allocated for the cache servers, per user served? Obviously, a large fast DiskDrive, is needed if caching a lot of large files. I'd also argue that DiskDrive probably should be located on a dedicated appliance.

Re: [WISPA] Any thoughts on a decent cache server
What I'd LOVE to figure out how to set up is a spoke and hub cache system. Let the MAIN site track the sites, then feed that data to all of the wpops. This way we'd keep most of the traffic of the internet (great to get content in single digit ms speeds rather than mid to high double digit ones) and we'd not have to have all of the traffic go back to the main site all of the time. But cache's don't work well for small, low volume sites. Oh well, another project for someday. marlon - Original Message - From: Travis Johnson To: WISPA General List Sent: Thursday, July 10, 2008 9:21 PM Subject: Re: [WISPA] Any thoughts on a decent cache server Tom, You can find all kinds of information if you do searches on squid. It's a very popular caching system that runs on *nix. The amount of RAM is directly related to the size of the disk cache. When we had servers 5 years ago (two of them in parallel) they were the fastest processors you could buy, with SCSI disk arrays in each one and I think 2GB of RAM each. I would guess in today's world you would be looking at 8GB or 16GB of RAM and very large disk arrays (6 disks x 500GB maybe). The other thing to consider is you now have another point of failure in your network. If a disk starts acting strange or the machine does a core dump, whatever you have re-directing traffic to the box may take 5 seconds to realize it's down and not send traffic to it. If you put it directly in-line with your traffic flow, you will have a complete failure of all internet services to your customers. :( Travis Microserv Tom DeReggi wrote: Any stats, on how much RAM is a good amount to allocated for the cache servers, per user served? Obviously, a large fast DiskDrive, is needed if caching a lot of large files. I'd also argue that DiskDrive probably should be located on a dedicated appliance.

Yeah. I don't think they do any cache units anymore. marlon - Original Message - From: George Rogato [EMAIL PROTECTED] To: WISPA General List wireless@wispa.org Sent: Thursday, July 10, 2008 9:22 PM Subject: Re: [WISPA] Any thoughts on a decent cache server Shift R means it won't take it from your computers cache.
