2.6 Summary

Older master/slave networks are rapidly being replaced by standard LANs which provide better performance, multi-vendor support, and integration with information networks. Of the current LAN standards, Token-Ring and Ethernet have the significant market share. Token Bus, because of the cost and complexity, has never become a major contender for the factory LAN market.

In general, Ethernet offers the most cost-effective and flexible factory floor networking solution available today. In a properly designed factory network, Ethernet provides excellent performance, reliability, and manageability. Since Ethernet is used with the 2572, it is discussed in more detail in the following section.
