Emulate

History

The project emulates began on May 13rd, 2002 with Hendrik Breitkreuz (alias Merkur) which was dissatisfied with the original customer EDonkey2000. Thereafter, seven additional developers joined the project. The source code was diffused for the first time for version 0.02 and it was published on SourceForge on July 6th, 2002.

The binary one was diffused for the first time on August 4th, 2002 for the version 0.05a. The " System" credit; on September 14th, 2004 was introduced into the version 0.19a. The Web site of the project emulates was open on December 8th, 2003. Since its creation, emulates was downloaded by more than 85 million people.

v0.42 (and following) makes it possible in addition to the network EDonkey to be connected to its own network called Kademlia (this network has the advantage of being able to do without waiters of connection).

v 0.47 C.A. introduces an option of jamming of protocol, in order to circumvent FAI practitioner the fastening of protocol (in France, Free or Club-Internet for example).

Currently (~2005) the project is maintained by 16 people: 2 developers, 2 managers of project (including the Breitkreuz founder), 3 testers, 9 tester-debuggers. The official site is maintained by 7 developers Web and 4 regulators.

February 21st, 2006, with 10:00, the Belgian federal police seized the largest waiter installed for the functions emulates, Razorback2. This operation constituted mainly a media move because the importance of the waiters in the operation of follower was decreased considerably with the arrival of the protocol Kademlia.

Semi September 2007 of many waiters (German) closed (source).

Basic concepts

Advantages of follower

Great base of user: an average of 20 million in 2007, which makes it excellent to find files rare.
the most completely Takes again protocol of edonkey 2000 and its improvements.
Manages the manager of correction of errors AICH (as effective as BitTorrent).
Manages the exchanges of sources between customers via the Kademlia network (allowing him to appreciably reduce the loads on the waiters). Besides HighID makes it possible to keep the sources a long time after disconnection of waiters ED2K and/or KAD.

Low ID

Mode LowID (low identification) is allotted by waiters and indicates computers customers which can not to be reached outside because they are behind parefeu (or national device) which was not correctly parameterized (nonopen ports), or whose end of address IP finishes with one zero (for example 123.45.67.0).

They can still download and send but will need the assistance (automatic) for waiters or customers of the Kademlia network to be able to be reached by other customers. That slows down considerably their progression in the queues.

Side waiters a customer of LowID consumes also much more data of bandwidth on than a customer of HighID due to the lowidcallbacks. Moreover, a releaser or a heavy uploader which employ a MOD of releaser such as MorphXT or Xtreme which are constrained to function in LowID (ex: with work, with the hotel) will note that it will have little control of its priorities of remote loading (particularly powershares) because the waiters limit their connection-forwarding for each customer.

System of credit

Usually the customers do not download a source as soon as the contact is made but must wait in the queue of the remote loading of the source until a place becomes available. This system of credit is employed to support the diffusion of the sources in giving priority in the queue to those which send (upload) more.

The customers are identified in a protected way. The customers can pass up to 10 times more quickly by the queue of a customer thanks to the system of credit. Each software customers memorize on hard drive how much data it received and sent each customer to which they they were connected. In order to avoid the cheating the appropriations of each customer are stored on the computers of the waiters where it were connected, rather than on their computer.

Derived or alternative software

The license LPG makes it possible to distribute modified versions of follower on the condition of providing the source code. Thus much mods leave with graphic improvements, skeletal optimizations, more options…

Mods

The mods (modifications) are software created starting from the source code of the most recent follower in order to add improvements or modifications.

Until approximately 2004 these mods could include a harmful function with the network: by exploiting a bug of follower these mods cheaters or leechers made it possible to circumvent the system of appropriations and thus to pass in priority.

Forks

The Fork S are created starting from the code of follower but do not follow the modifications of the original version: they follow their own development.

Bearings

The bearings (ports in English) are compatible software developed for others operating systems.
