The term "MSN Messenger" is quite ambiguous, as Microsoft uses the term to relate to several different parts. Messaging solution. You chat through "MSN Messenger Network". The most popular program used to connect to MSN Messenger Network is "MSN Messenger", and the language used by programs in MSN Messenger Network is "MSN Messenger Protocol".

What is MSN Messenger Network?

MSN Messenger Network is a real-time communication network from Microsoft. Released in July 1999, it was not the first communications network, nor would it be the last. MSN is one of the top 4 personal real-time communication networks. By March 2003, the exclusive MSN Instant Messenger network had far fewer users than AOL Instant Messenger and ICQ, but more than Yahoo Messenger.

What do programs do on the MSN Messenger network?

The programs on your computer are called "clients." It connects to MSN Messenger servers via the Internet. Specifically, the client sends and receives messages through the server and other clients. Some information is not processed and is simply passed through the server. For example, when sending a real-time message, the command "here is a message, pass it on" is processed by the server, but the message itself is only passed to the client through the server.

Microsoft has released two MSN Messenger clients: MSN Messenger (also called ".NET Messenger") and Windows Messenger. Microsoft recommends MSN Messenger to most Windows users, including Windows XP, where Windows Messenger is bundled with the operating system. Other people and companies have written "third-party" MSN Messenger clients. You can see some clients in the resource page list. MSN Messenger is generally considered the de facto standard client, and most other clients determine their direction from its behavior, so it is considered the "official client" online.

Microsoft has never publicly released their Messenger server, and the official client does not allow you to connect to non-Microsoft servers. Currently, several people have written third-party server-side servers, which can be found on the resources page.

The "language" used for communication between two computer programs is called a "protocol." The rules for message sending between MSN Messenger client and server are called "MSN Messenger protocol". The rules for sending messages from one client to another through the server are referred to here as the "MSN Client Protocol".

What is the MSN Messenger protocol?

MSN Messenger consists of a series of commands that can be sent on the client and server. For example, when someone in your contact list goes offline, the server sends your client a message like this: FLN myname_123@hotmail.com. When receiving this command, the client should move the user from the online user list to the offline user list.

The MSN Messenger protocol has undergone several modifications in recent years.

At the time the protocol was drafted (October 2003), Microsoft's servers allowed clients to use versions 8, 9, and 10 of the protocol. Personal protocol versions are often written by "MSNP8", "MSNP9" and "MSNP10".

This site aims to completely define the MSN Messenger protocol and the characteristics of the MSN Messenger server, so that third-party software developers can write their own programs to interact with the network. So far, only MSNP8 has been documented, with some topics available in MSNP9 and MSNP10.

Information about the protocol can be obtained by reading the official IETF draft, reading various source codes, analyzing data packets, analyzing the official client, and writing programs. Much of this work was done by some other MSN Messenger research group, and we just documented it. If you discover something new about the protocol, please post it on the forum.

What is the MSN client protocol?

The MSN client protocol consists of messages sent between clients. For example, when you say "hello" to your friend, your client sends hello as the body of the message to their client.

Until recently, the development of the MSN client protocol was relatively organic - one official version of the client would behave differently from other clients, and you could only guess what specific behavior it would have ( This sentence cannot be translated). Recently, attempts have been made to impose a version numbering system. As of October 2003, 3 versions of the MSN Messenger client protocol have been found, which are called "MSNC0", "MSNC1", and "MSNC2" on this site.

This site aims to completely define the MSN Messenger protocol and the features of the official client so that third-party software developers can write their own programs and network interactions. We hope to eventually fully define all versions of the protocol. This site only defines the behavior of the official client and it informs us about how other clients behave predictably. The author of this website does not use the official client, so he cannot make a fair judgment on the subject. Some other sites cover this subject well.

What does Microsoft think about all this?

We have no relationship with Microsoft, only very limited communication. We know that at least some Microsoft employees are aware of the site and community in general, but the company's policies seem to be ignoring us. Microsoft has not made any formal attempts to remove third-party clients from their networks, but they have never tried to communicate with us or give us assurances about the future. They have become very good at accepting bug reports that pose security risks.

Compared with AOL (the owner of AIM and ICQ), Microsoft's agreement with third-party developers is very good. This probably doesn't reflect any philanthropic part: third-party clients drive growth in Microsoft's network of users, and (unlike AOL) we're not a direct threat to their revenue.
