Implementing VoIP quality of service (QoS) for reli- able voice communication over Industrial Ethernet

Ethernet is fast becoming the preferred method for all industrial communications—including voice and other real-time traffic that is sensitive to delay and data loss. This white paper explains how VoIP QoS classi- fies, prioritizes, and shapes traffic to provide reliable voice communications over an industrial network.

Introduction For many years, serial interfaces such as current loop, RS-232, and RS-485 have been the preferred meth- ods for industrial communications. Ethernet offers high reliability with the proven ability to adapt to changing environments, especially new types of media (coaxial cable and wireless transmission, for example). As Ethernet becomes the common interface for intercon- nection, it becomes natural to use this resource for all communications requirements. Adding voice commu- nications capabilities, by either extending a tele- phone or offering a hot-line/party-line facility, can be as easy as plugging in a box and a handset.

Why Industrial Ethernet? While serial device networks offered a measured level of efficiency, their implementation was very inefficient. Often these networks were made up of many smaller networks. Strings of similar equipment on single-network segments were laid on top of each other over the shop floor.
