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. Squid (and probably other caches) support something similar, in the form of parent and child caches. It sorta works backwards from what you described, but the net benefit would be similar. Basically, you set up caches at your POP locations, each of which is configured to use a bigger cache in your NOC as their parent cache. (Of course, you have to set up suitable firewalling at every tower, to redirect traffic from that POP's customers to the local cache.) Customer types in ebay.com, goes to their local cache. If the information they want isn't there, that cache checks with the big cache in your NOC. If it also doesn't have that page, it fetches it from the public Internet, and passes it on down. It's not a push system, but that's probably alright. I'm not sure how well a push system would work anyway. Anything like, say, the monthly crop of Windows Update downloads, they'd get spread out to the individual caches quickly enough anyway. David Smith MVN.net WISPA Wants You!

Re: [WISPA] Any thoughts on a decent cache server
You can do this as well with Mikrotik. MT is very, very simple. We have seen avg savings of between 20-40%. With 25-30% being avg. Also, you can specify what sites you want to cache, typically done by IP, but you could also say that you only want to cache sites that are on different areas etc if you got the IP ranges that you wanted to use. Something else, is that you can specify a bit for the cache hit data. This means, you can throttle data that comes from your cache differently than the customers standard package! So, data that comes from your cache, maybe goes at full wireless speed etc. We usually drop in either a 80 gig or 250 gig SATA2 drive into our PoweRouter 732s. If they have a large customer base, we drop in 2 gig of ram just to be on the safe side. -- * 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/* David E.

Re: [WISPA] Any thoughts on a decent cache server
Hi, Are you somehow redirecting traffic to the MT box, or having all the traffic go through the box? Cache hit rates are going to depend on the size of the network... a 250GB drive would only cache about 4 hours of http traffic on my network... hit rates would be less than 5% I would guess. I've also heard MT doesn't work very well doing caching. Has this changed since v3 was released? Travis Microserv Dennis Burgess wrote: You can do this as well with Mikrotik. MT is very, very simple.

Re: [WISPA] Any thoughts on a decent cache server
Keep in mind that if you move 250 gig, that does not mean that it will cache that.

Re: [WISPA] Any thoughts on a decent cache server
The people that we had the most problems with were web designers who's sites were cached and they couldn't easily see their changes. We always told then to add no cache to their sites. Thats an easy one to fix. Tell them to press [CTRL] F5. Thats all it takes on virtually any standards compliant cache. The real pain is when shopping carts or the like do not work. We have had far better success having Mikrotik redirect/DST-NAT too Squid then using the Mikrotik cache. Far fewer websites with issues. Running the cache on Mikrotik really shot the CPU load up on the Mikrotik as well. Strange the CPU load on the box running Squid is barely anything. In the process of upgrading our network and bandwidth. Gonna try the Mikrotik cache again to see if its improved any. Its so much simpler doing it with an inline Mikrotik box. Matt WISPA Wants You!

Re: [WISPA] Any thoughts on a decent cache server
You can build a good squid box with lots of memory and fast hard drives and get good results. The squid setup is also nearly infinitely tunable, as opposed to the ones in Mikrotik and StarOS which have a pretty vanilla configuration. Being able to tune the cache parameters helps a lot, along with putting the cache directories on a separate hard drive and/or multiple ethernet cards to maximize the traffic flow. I have also used caching servers during heavy bandwidth demand or outage times to offload some of my browsing traffic to cable or dsl connections at the edges of the network. From a deployment perspective, I have gotten the best results by letting any questionable customers bypass the caches. 95% of my customers are on 192.168.0.0/16 addresses, so we had a rule that directed the /16 network to the cache. Customers with public IP addresses do not go through the cache. That way, someone with a problem going through the cache would have to upgrade to a static IP so that they could bypass it.Relatively simple, and effective.

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.

Re: [WISPA] Any thoughts on a decent cache server
I don't know if it's better now, but when I tried to use MT as a cache it REALLY slowed things down. Speeds were higher, but the time from click to page start went up a LOT. So the internet FELT much slower. I loved my old Cobalt CacheRAQ. Wish I could find something like that again.

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
The drive should be big. But probably doesn't need to be that big. Remember that a drive is MUCH faster than the average network.

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.
