Introduction

new devices to the network, change device addresses, and remove devices from the network without having to reconfigure the SmartSTACK 10 ELS10-26.

The Open System Interconnection (OSI) Reference Model, developed by the International Standards Organization (ISO), identifies the levels of functionality inherent in each of its seven layers. The SmartSTACK 10 ELS10-26 operates at the Media Access Control (MAC) sub-layer of the Data Link layer. Figure 1-2 shows the OSI Reference Model.

Because the SmartSTACK 10 ELS10-26 does not process any Network Layer information, it provides a high level of performance in terms of packet throughput. In addition, the SmartSTACK 10 ELS10-26 does not need to learn network topology, requiring less programming and configuration time.

Store and Forward Switching

As an intelligent Ethernet switch, the SmartSTACK 10 ELS10-26 uses store and forward switching. Store and forward switching allows the SmartSTACK 10 ELS10-26 to temporarily store packets until network resources, typically an unused link, are available for forwarding. This allows for complete error checking, and limits the amount of time between when a device requests access to the
