All what I’m going to discuss below is only for ADSL2+ heavy downloading users. And they are just some knowledge and experiences that I'd like to share. I've tried to make everything accurate as possible, but if you think information is wrong. Please tell me.
Any questions and comments are more than welcome.
The topics will include
• Which plan is the best?
• Can I just pick any modems? Does filter/splitter really matter?
• Why are my BT and Emule so slow?
• Will I be caught by downloading “The Pursuit of Happyness”? What about Japanese porn movies?
Which plan is the best?
Well, I guess everyone has their own best plan, in other words, the best plan for me wouldn’t be the best for you. So what I could recommend you is to do some studies. There is one one-stop place you can go, www.whirlpool.net.au . On the website, you can just browse to find your preferable ISP or do some comprehensive searches from all available plans in Australia. However, please keep this in mind, the nearer your location is close to exchange, the faster your ADSL 2+ would be. It also depends on the quality of the cable connecting between your modem to the exchange.
Ok, having said those, here is the listing of things can help you figure out how fast your ADSL2+ could be theoretically.
1. Find out where your exchange is located http://forums.whirlpool.net.au/index.cfm?a=wiki&tag=Australian_Exchange_Guide
2. Go to www.whereis.com and find out the cable length between your exchange and your location. Remember, the distance will not be accurate to or even way different from the cable length, so don’t feel disappointed if the cable is over 5KM or too excited you are sitting next to the exchange.
3. The last step is to go to this page ( http://forums.whirlpool.net.au/index.cfm?a=wiki&tag=DSLAM_speeds ) and calculate the theoretical speed of your ADSL 2+.
There are other things you might want to consider when choosing your best plan,
• Upload speed. Very import, at least 1MB I have to say.
• Static IP if you want to host a server or to remote connect to your PC from work (maybe check if you can enjoy the “Dreamgirls” tonight)
• Off-peak download. Some ISPs offer off-peak downloading data limit so you can get a bit more data limit by scheduling your download when you are asleep.
• VOIP. Voip can be integrated with your plan by some ISPs. If you just hate to dial hundreds of number before calling your girlfriend in China, you might try VOIP. It’s convenient but a bit more expensive than some calling cards.
• Data limit. Personally, I suggest those who download movies and TV plays often need at least 30GB, but for people who just enjoy watching the high-speed download, I would say 300KB/sec * 3600 sec/hr * 24hr/day * 31day/month / 1024KB/MB / 1024MB/GB = 767GB
• Friendly support. If you want friendly supports, you can log in to the whirlpool’s forum and have a look at what people say about their ISP. I never call my ISP after my broadband has been installed.
• There are other factors you also need to consider, for example contract length, free modem (?), installation fee etc.
Can I just pick any modems/router? Does filter really matter?
Most ISPs will allow you BYO, so you have choices of buying a modem by yourself or using one of the modems your ISP offers. There are a huge variety of ADSL2+ modems in the market ( www.staticice.com.au ). As I’m not an expert of modems, I won’t be able to give you a listing of good ones and bad ones. However, as myself is a heavy downloading person, I do know what the factors you need consider before making the decision. Because we use BT and Emule, they both will have massive connections trying to be established to your modem/router. As a result , your modem/router would be very busy dealing with those connections all the time. If your router is not good enough, it will be restarted every a few minutes.
Now you know why router is very important to P2P downloader. The one what I have been using is Billion 7402GL (http://www.billion.com.au/product/wireless/bipac7402gl.php). It’s one of examples that perform very well during P2P downloading. I used to have one router from Dlink, which was a nightmare experiences. The minute I started my P2P download, it restarted and then it restarted around every five minutes until the download was finished or sometimes I had to stop downloading to browse the Internet.
Almost every modem you purchase will give you one free filter/splitter, which is good in most cases. The one that I currently use and am happy with is ACS ADSL 2/2+ 901E2+ Inline Filters (http://www.warcom.com.au/shop/flypage/adslaccess/2270). It will cost you about 20 bucks, but it’s really worth it. Although everyone won’t be able to get the same improvement after using it due to the different line qualities, you will definitely notice the increases in your download speeds or line quality.
Why are my BT and Emule slow?
Ok, you’ve got the best modem you can find in the world, and you bought an ADSL2+ line filter, but after you run your BT program or Emule, you find the speed is way slow than what you expected. To find out if your ISP throttles your P2P traffic, just try to download some files from Microsoft or your ISP website. If you see the speed you are supposed to get, then it means your ISP runs something called traffic shaper somewhere to monitor P2P traffic.
The reason they do this is Bittorrent traffic is consuming 40-60% of ISP’s traffic. Unfortunately, there ain’t many choices for you. But the lucky thing is they just shape the traffic, not block them yet. As far as I know, the only choice we have is to encrypt P2P traffic. Currently, there are three bittorrent clients that support encryption, Azureus, Bitcomet and µTorrent. There will be more and more clients will implement this feature to counter this bandwidth throttling. However, ISPs have been aware of it too, and they have been trying to implement new weapon to defend bandwidth. It’s a traffic shaping battle and it will continue.
Anyway, you can turn on encryption feature for Azureus, Bitcomet, µTorrent and Emule. Once you have done it, you will see the huge differences. If you still don’t see any improvements, try to find some quality tracker for BT or source for Emule.
Will I be caught by downloading “The Pursuit of Happyness”? What about Japanese porn?
Let me answer the simpler one, no, most likely you won’t be caught by downloading Japanese porn movies. But you will be most likely caught by downloading American movies and TV plays especially if you use BT. One of the reasons is that there are some fake seeds out there. They seem they are the latest movies or TV plays, but they actually are SONY Entertainment or other movie companies. They use popular movies or TV plays as bait. Once you download it, you will be busted, your IP will be logged and then they will send a letter to your ISP. Later, your ISP figures out that the IP used at that time belonged to you, and sends a warning letter to you for the first time. The ISP probably will warn you that you have downloaded “The Pursuit of Happyness” on 24/01/2007, and the service will be terminated if you are continue distributing copy-righted materials.
However, there still is one way to protect yourself, PeerGuardian. It can be downloaded from here http://phoenixlabs.org/pg2/ Basically, what it does is to block a range of IPs while you use P2P. This is a tutorial that shows you how to configure it. ( http://www.winmxworld.com/tutorials/peerguardian.html. ) You also need to update the IP blocking ranges after installation, here is a couple of good places you can find out the latest ipfilters.dat
