Westwood Online is a peer-to-peer gaming network which uses several protocols for chatting/gaming. The main portion of WOL is based on the IRC protocol. There are two versions of WOL: the WOLv1 protocol which is used by Westwood Chat client (later called Westwood Online). This client connects to a meta-server for chatting and arranging games. The Westwood Chat Client is an application used to launch a game and is not integrated into the game itself. Later games supported the WOLv2 protocol internally, you could search for games and chat without having to exit the game.

WOLv1 clients connect to two servers hosted at and The first one uses a modified IRC server protocol and is used for chatting, and negotiating games. The client (not the protocol) sets up games and sends game data to the server which then sends it to other clients. This server will be called WOL IRC server in this wiki. The gameres protocol is a binary protocol used for sending game results information to the server after a game is over.

WOLv2 uses many servers. First, clients join the server which is a meta-server. This server sends list of chat servers (which are enhanced version of servers), gameres servers, ladder servers, wdt servers, port mangler server etc. All of these servers will be described below.

Because WOLv1 and WOLv2 are nearly identical, both are covered together here with the differences highlighted.

WOL ServServ ProtocolEdit

WOL ServServ is WOLv2 service only. It using standart IRC protocol concept of commands and server replyes but is not used for any chat/games functions. This server uses hostname and port 4005. This is hardcoded on client side. Server is used for Gateway stuff - all WOLv2 clients firstly connect to this server and get list of possible WOL IRC servers. They are divided geographically over the world ie. US West, Europe, Asia.

WOL Ladder ProtocolEdit

This is a WOLv2-only textual protocol. It describes a players rank/wins/losses/disconnects or badges of honor for players/clans.

This server does not keep a live connection with the client, a connection is only made for transferring ladder data and then closed.

WOL GameRes ProtocolEdit

Is an binary protocol and is used by all client versions. WOLv1 using hardcoded hostname and port 4807. WOLv2 recives hostname and port throught ServServ server. After game is designed through WOL IRC protocol and is done, all clients sends Game Resolution. This is way how WOL Ladders works.
