Universal Plug and Play(UPnP)

The UPnP architecture allows peer-to-peer networking of PCs, networked appliances, and wireless devices. It is a distributed, open architecture based on established standards such as TCP/IP, UDP, HTTP and XML.

The UPnP architecture supports zero-configuration networking. A UPnP compatible device from any vendor can dynamically join a network, obtain an IP address, announce its name, convey its capabilities upon request, and learn about the presence and capabilities of other devices. DHCP and DNS servers are optional and are only used if they are available on the network. Devices can leave the network automatically without leaving any unwanted state information behind.

Other UPnP features include:

Media and device independence

UPnP technology can run on many media that support IP including Ethernet, FireWire, IR (IrDA), power lines (PLC) and RF (Bluetooth, Wi-Fi). No special device driver support is necessary; common protocols are used instead.......

What is Bittorrent?

What it is
   Bittorrent is a cooperative distribution of content where each individual who is downloading (and those who have downloaded) the content use their upload capacity to give the content to others.

Traditional distribution of content relied upon a single server providing the content.  However, this creates a vicious circle where the distributor is punished as the content becomes more popular.  The more people that download the content, the higher the bandwidth cost to the distributor.  If the content becomes very popular and the server is flooded with requests for download, then the server crashes and no one receives the content.  Thus, only those with special equipment and lots of money were able to adequately distribute content.

Bittorrent allows individuals, and small enterprises, to distribute their content as effectively as traditional distribution, but at a small cost.  In bittorrent the popularity of......

   I tested ten bittorrent clients for speed and all ten, after proper setup, ran at essentially the same speeds.  Given their equal performance the decision on which is best was based primarily on support and features.  Other than Miro and Halite, clients had low CPU use.  The amount of RAM use by these clients varies greatly, but with the amount of RAM that the average user has on their system nowadays, that is not much of an issue.   The RAM use on my computer is noted here for your reference.  The use on your computer may vary, but these client's use of RAM relative to each other should be in line with my numbers.  I have linked to screen shots of the Top Picks and Other Suggested Clients as the interface of these clients may be a factor in your decision of which to use.

   The features that I considered were first the basic ones that every user would want, Encryption (helps with ISPs that interfere......

BitComet, A Bittorrent application that i has been use for quite some time. But recently i facing download speed slow on my bitcomet application. But i applied some few tweak for Bitcomet bittorrent application.

1. Hack the max TCP connections on Windows XP

If you are currently using on Windows XP SP2, your Windows TCP connections are limited to a maximum of 10. I highly recommend your modify Windows TCP/IP.sys with LvlLord Patcher to get better performance bittorrent download speed. If not modifying Windows TCP/IP.sys, It will seriously hurts your bitcomet download speed because it wont let you connect to a high amount of ip numbers.

2. BitComet Connection Preferences

   Torrent Client Configuration for speeding  

   In order to apply these tips you need to know your maximum up- and download speed. You can test your bandwidth over here (stop all download activity while testing). Also make sure that you applied the tips provided in our previous posts.
   Note that there’s a huge difference between kb/s (kilobits/second) and kB/s (kilobytes/second). To be precise, kB/s = kb/s divided by 8. In this tutorial we use kB/s (like most torrent clients do). This means that you
might need to calculate your max speed in kB/s yourself if the speedtest only gives you the results in kb\s (so divide by 8 then).

   Settings 1-4 can be found in the options, settings or preference tab of most torrent clients.

1. Maximum upload speed

   Probably the most important setting there is. Your onnection is (sort of) like a pipeline, if you use you aximum upload speed......

Distributed hash table(DHT)

      Distributed hash tables (DHTs) are a class of decentralized distributed systems that provide a lookup service similar to a hash table: (name, value) pairs are stored in the DHT, and any participating node can efficiently retrieve the value associated with a given name. Responsibility for maintaining the mapping from names to values is distributed among the nodes, in such a way that a change in the set of participants causes a minimal amount of disruption. This allows DHTs to scale to extremely large numbers of nodes and to handle continual node arrivals, departures, and failures.

      DHTs form an infrastructure that can be used to build more complex services, such as distributed file systems, peer-to-peer file sharing and content distribution systems, cooperative web caching, multicast, anycast, domain name services, and instant messaging. Notable distributed networks that use DHTs include......

What is a .torrent file?

This is a small metadata file. Metadata here means that the file contains information about the data you want to download, not the data itself.
Your BitTorrent client needs the .torrent file to connect to the tracker (see below) and download the actual data you're interested in.

What are seeds?

A seed is a client that has a complete copy of the data of a certain torrent. Once your BitTorrent client finishes downloading, it will remain open until you click the Finish button (or otherwise close it). This is known as being a seed or seeding.

What are leechers?

A leecher is a client that is currently downloading the data of a torrent. A leecher does not have the complete file, otherwise it would be called a seed.

What is a tracker?

A BitTorrent tracker is a service on the internet that assists in the communication between BitTorrent clients. When you open a torrent file, your machine contacts the tracker and asks for a list of seeds......
