Description
The mLAN protocol was originally developed by
Yamaha Corporation
is a Japanese multinational corporation and conglomerate with a very wide range of products and services. It is one of the constituents of Nikkei 225 and is the world's largest musical instrument manufacturing company. The former motorcycle d ...

mLAN exploits several features of the
IEEE 1394
IEEE 1394 is an interface standard for a serial bus for high-speed communications and isochronous real-time data transfer. It was developed in the late 1980s and early 1990s by Apple in cooperation with a number of companies, primarily Sony ...
(FireWire) standard such as
isochronous transfer and intelligent connection management. There are two versions of the mLAN protocol. Version 1 requires S200 rate, while Version 2 requires S400 rate and supports synchronized streaming of digital audio at up to 24 bit

In computing, a word is the natural unit of data used by a particular processor design. A word is a fixed-sized datum handled as a unit by the instruction set or the hardware of the processor. The number of bits or digits in a word (the ''word ...

sample rate
In signal processing, sampling is the reduction of a continuous-time signal to a discrete-time signal. A common example is the conversion of a sound wave to a sequence of "samples".
A sample is a value of the signal at a point in time and/or s ...

In telecommunications and computing, bit rate (bitrate or as a variable ''R'') is the number of bits that are conveyed or processed per unit of time.
The bit rate is expressed in the unit bit per second (symbol: bit/s), often in conjunction w ...

can interact with mLAN-compliant hardware via any
OHCI-compliant FireWire port. mLAN consumes the entire bus bandwidth when operating and non-mLAN devices cannot share the same Firewire connection, so it is not possible to use hard drives, optical drives or other sound devices on the same Firewire bus when mLAN Manager software is running.
The transport layers of mLAN have been standardized as
IEC 61883.
End of life
By 2005, over 100 manufacturers were part of the mLAN Alliance
Audio Interface Manufacturers' Round Table
/ref> however very few actual products had surfaced.
As of early 2008, mLAN appeared to have reached the end of its product life. Third-party developers discontinued or retracted their mLAN products from the market, and Yamaha itself ceased any new releases of mLAN hardware or updates to the mLAN software and drivers. Even though more recent FireWire based products from Yamaha could interoperate with earlier mLAN devices using a computer, any mention of mLAN is notably absent from new product announcements and driver updates.
