There are also a number of packets used by Forge - see FMLPacket.
The most relevant ones are

• EntitySpawnPacket - which gets passed to a user-supplied function when the entity spawns.
• EntitySpawnAdjustmentPacket - used to adjust an Entity's location
• OpenGuiPacket - opens a Graphical User Interface screen on the client or server.
