Sample text

The flat car has its own bar code, which is used at the switching yard to reroute the flat car to the destination. Half way across the country, Eastern Rail now reads the bar code on the container, loads it onto another flatcar, and sends it the rest of the way across the country through several more switching yards. In this analogy, the bar code on the container is like the TCP/IP header. As the frame (container) enters the first Ethernet network (Western Rail), the TCP/IP header is read and an Ethernet header (flatcar bar code) is attached which is used to forward the packet through several Ethernet switches (railroad switching yards).

When the Advanced Research Projects Agency Network (ARPANET) gave birth to the internet, things started to get interesting. In order to provide web hosting services, dedicated data center facilities full of servers began to emerge. Initially, these data centers employed the same LAN networking gear used in the corporate data centers. By the end of the 1990s, Ethernet became the predominant networking technology in these large data centers, and the old LAN-based networking equipment was slowly replaced by purpose-built data center networking gear.

We will provide more information on software defined networking in Chapter 9. Physical security means protecting the data center facility from disruption in power, network connections, or equipment operation by fire, natural disaster, or acts of terrorism. Most data centers today are built with this type of physical security in mind. Cloud types Large cloud data centers can be dedicated to a given corporation or institution (private cloud) or can be shared among many different corporations or institutions (public cloud).
