RuggedCom Documentation:
	Ethernet in Substation Automation Applications This paper looks at the key issues and requirements for Ethernet in the substation environment and for substation automation applications requiring real-time performance. Specific topics addressed are: EMI phenomena and atmospheric conditions in substations which can affect network performance, new standards introduced by the IEC and IEEE that establish new EMI and environmental requirements specifically for communications networks (i.e. Ethernet) in substations, critical Layer-2 features of modern Ethernet switching hubs (i.e. switches) which enhance real-time deterministic performance as well as fault tolerant loop architectures and network redundancy.
	Zero-Packet-Loss™ in the Substation This paper explores the emerging trends of using the network to perform mission critical real-time control applications, the new IEC and IEEE standards for communications systems and networking equipment in the substation, and the reasons/needs for Zero-Packet-Loss™ in the substation.
	The Need for "Substation Hardened" Ethernet Switches What Does It Mean to be ‚Substation Hardened™? This paper explores this question in light of the special issues of substation networking and new IEC & IEEE standards.
	A Comparison of Dispersed Topologies for Ethernet The trend for automation and control networks in various industries is to use Ethernet as the physical layer. This leverages a vast array of both networking equipment and end devices. However, deploying a real-time control Ethernet network in a geographically dispersed area has a unique set of challenges. When the distance between end stations is many kilometers, the network is still logically a LAN, but physically is anything but local. Cabling costs can be significant in such a network; choosing a topology that minimizes these costs yet provides for a robust, fault tolerant network is more difficult. This paper compares several different topologies that address these needs.
