Use UPNP on the intranet to download BT eMule to speed up significantly

It has been a problem for internal users to download BT (Bit-Torrent) and eMule (e-mail, eMule). In fact, most of the time, because the mapping port is not set, the communication with the outside world is not smooth when downloading BT and eMule. Although there are many articles on how to set the router mapping port to improve the download speed, it is absolutely good. Most people are still very inconvenient, and setting up changes to each port map can be a cumbersome task when you reinstall your system or have multiple computers.

The router introduced after 2002 basically has a function called UPNP (Universal Plug and Play) and is enabled by default. If you want to know more about UPNP, you can search online. Related introduction. For general applications, UPNP can't play its characteristics. It can play an unusual power for P2P downloads such as BT and eMule. The mapping port most commonly introduced on the Internet is BT and emule download acceleration. In fact, it can be automatically completed by UPNP, but this requires software to be added to support. Nowadays, there are several types of BT download software, such as UPcom framework mapping port of bitcomet, UPNP random port mapping of emule, UPNP automatic mapping of Tuotu and manual addition. Although these softwares use different technologies, they have only one purpose. Open a highway for P2P download through UPNP.

a contrast

UPnP user interface Although now BT, eMule download software can increase download speed by using the UPNP in different ways, but the effect may not be able satisfactory. For example, the UPNP framework used by Bitcomet can only be used in Windows XP, and it is not available to Win9x, Win2000 and Win2003 users. WinXP users are not immediately available. You need to add new components and set up fire prevention before you can enable the UPNP framework. There are certain technical requirements for users. The UPNP setting of the eMule (verycd version) is completed by the foreign MOD. The UPNP needs to be detected every time it is turned on. The compatibility is not satisfactory. The user can only know whether the UPNP is enabled in the connection information box. Prompt, and the inability to record UPNP settings is not intuitive and user-friendly for the user. Tuotu is a rookie in the download software and has done a great job in UPNP compatibility and operability. When using for the first time, you need to find the UPNP device in the UPNP information of the rabbit to get detailed data feedback. After successfully finding the UPNP device, the UPNP information bar will appear. In the UPNP information bar, the user can intuitively understand the UPNP port information that the local computer and other intranet computers successfully open, and provide very few manual mapping port functions. Pulling rabbits or other software to manually map ports, this design is simple and user-friendly, it is worthy of praise. //This article from the application of computer hardware and software network www.45it.com reproduced please specify

Second, compatibility testing

actual download the next test in the opening and closing UPNP able to BT, How much does the emule download increase? Since the system uses Windows2003 SP1, I only use the rabbit as the test object. The network environment is 2M ADSL (maximum download speed 256k), 100M network card, hardware is P42.4G, 1G DDR memory, 250G hard disk. The routers are the newer Linksys WRT54GC and the old TP-link TL-R420. First test the rabbit UPNP compatibility, take the rabbit to find the UPNP device of the two routers, re-enter the rabbit setting bar and see the UPNP control bar, see that the rabbit has successfully mapped the UPNP port (the blue word is displayed as automatic mapping). Here to remind, sometimes only one port can be successfully mapped (normally 2 UPNP auto-mapped ports), then just manually add a mapping port, you can solve it and will not appear again (note the description of adding a port should not repeat ), the problem is not big but needs attention.

Three, UPNP automatic mapping to increase the speed of 6 times!

After the compatibility test passed successfully, first select a 6.6G on the BT search of the rabbit to be a very popular serial download. Because of the time relationship, each router downloads for about 1 hour, and the rabbit BT is set to ADSL routing sharing. . First turn off the UPNP on the two routers, so that the rabbit can not use the UPNP mapping port, start downloading this 6.6G series, see the source number has about 40 connections, the maximum available source is about 400, the average download speed is about 28K, the peak 41K, download about 100M in an hour. Then turn on the UPNP of the two routers, find the rabbit and find the UPNP port successfully, and the other settings are unchanged. Re-downloading this TV series with BT, this connection is fast, the download speed is only used for 5 seconds, the peak value is 226K at the fastest, and the average speed is about 180K. Download 650M in one hour, 6 times faster than turning off UPNP! In the same environment, a UPNP can affect the speed as much as this. It can be seen that the mapping port has a huge impact on P2P download.

next start testing eMule download, or use this test rabbits, some friends might ask why not verycd of emule, I'm sorry, could not be opened because verycd of emule UPNP router on the test, while the rabbits The emule can open the UPNP of the two test routers, so I have to give up. Please rest assured that the emule used by the rabbit is 0.47a core. After rigorous testing and optimization, the performance is better than that of the verycd emule. First shut down the UPNP on the two routes and download a 4.2G HD version of the movie. The rabbit emule can be successfully connected, but the high ID of the emule (the high ID of the user is helpful to improve the download speed of the emule). In the case of only the Low ID, according to the emule rule, the connection time and the queue time will be greatly increased.

A simple test reveals that UPNP does have its existence value. Although UPNP is usually an idle function, it can be used when needed. Download P2P without the cumbersome settings of the router, you can get strong performance. From this rabbit test, it can be explained that as long as the P2P software is UPNP, UPNP can give you several times the performance return (when P2P has no source, 啥 optimization can't speed up).
