- Description: This paper describes the use of mLAN (music Local Area Network) to solve the problem of audio routing within hotels and convention centers. mLAN is a Firewire based digital network interface technology that allows professional audio equipment, PCs and electronic instruments to be easily and efficiently interconnected using a single cable. In order to solve this problem, an existing mLAN Connection Management Server, augmented with additional functionality, has been utilized. A graphical client application has been created that displays the various locations within a hotel/convention center, and sends out appropriate routing messages in Extensible Mark-up Language (XML) to an mLAN connection management server. The connection management server, in turn, controls a number of mLAN audio distribution boxes on the firewire network.

- Description: The Plural Node architecture is an implementation architecture for professional audio devices that adhere to the “Audio and Music (A/M)” protocol. The Plural-Node implementation architecture comprises two components on separate IEEE 1394 nodes – a “Transporter” component dedicated to A/M protocol handling, and an “Enabler” component that controls the Transporter and provides high level plug abstractions. An Open Generic Transporter specification has been developed for the Transporter component. This paper details an open design and implementation for the Enabler component that allows for connection management via abstract, mLAN plugs.

- Description: The Plural Node architecture is an implementation architecture for professional audio devices that adhere to the “Audio and Music (A/M)” protocol. The A/M protocol determines how audio and MIDI data are transported over IEEE 1394 (firewire). The Plural-Node implementation architecture comprises two components on separate IEEE 1394 nodes – a “Transporter” component dedicated to A/M protocol handling, and an “Enabler” component that controls the Transporter and provides high level plug abstractions. Low level control of individual Transporters occurs within the “Hardware Abstraction Layer” (HAL) of the Enabler. Device manufacturers write their own plug-ins for the HAL to interact with their Transporters. The Open Generic Transporter specification provides an open interface between the HAL and Transporter for the convenience of device manufacturers.

An XML-Based Approach to the Generation and Testing of mLAN Sound Installation Configurations

- Description: An application, called the mLAN Installation Designer, has been developed that enables the user to graphically design and validate an mLAN sound installation. This application is built upon a model of mLAN systems that is defined by an Extensible Markup Language (XML) Schema, ensuring cross platform portability and future scalability. The XML Schema provides sufficient flexibility to form the basis for a standard effort to describe the configuration of IEEE 1394 based sound installation environments. The output from the mLAN Installation Designer application file is an XML document, consistent with the defined schema, which allows a configuration tool to configure the mLAN devices for automatic operation during deployment of the system.

A New Connection Management Architecture for the Next Generation of mLAN

- Description: mLAN is a networking technology based on the IEEE 1394 standard that allows for the transport of audio and music control data between audio devices. In the original implementation of mLAN, software within each mLAN node hosted by an audio device contained high level plug abstraction and connection management software. mLAN-B is the next generation mLAN architecture that splits the connection management function between workstation and device. The high level connection management and plug abstraction capability resides on the workstation, while a thin low level connection management capability is left on the device. This approach reduces cost and complexity on the device side and ensures that mLAN systems can be easily upgraded.

- Description: A connection management server has been developed that enables connections to be made between mLAN-compatible audio devices, via a client web browser on any web-enabled device, such as a laptop or PDA. The connections can also be made across IEEE1394 bridges, and will allow for the transport of audio and music data between mLAN devices on the same or separate IEEE 1394 buses. Multiple users will be able to make and break connections via the server.

- Description: 'mLAN' describes a network that allows for the transmission and receipt of audio and music control data by audio devices. IEEE 1394 was chosen as the specification upon which to implement mLAN. mLAN has built on IEEE 1394 and related standards, introducing formats, structures, and procedures that enable the deployment of IEEE 1394 within a music studio context. This paper discusses these standards, their implementations, and provides pointers to the future evolution of mLAN.
