Example text

Although these networks can be designed as a physical ring, like Ethernet, they are often designed as a star or extended star. But logically, they operate like a ring. The Hierarchical Network Model Hierarchical network design involves dividing the network into discrete layers. Each layer provides specific functions that define its role within the overall network. By separating the various functions that exist on a network, the network design becomes modular, which facilitates scalability and performance.

Lower layers process and send the request to the web server. 4. Web server receives HTTP requests and sends a TCP acknowledgement back to the request- ing web client. 5. Web server sends the HTTP response down to the transport layer. 6. TCP encapsulates the HTTP data with a TCP header. 7. Lower layers process and send the response to the requesting web client. 8. Requesting web client sends acknowledgement back to the web server. If data is lost at any point during this process, it is TCP’s job to recover the data.

Video over IP has the same performance issues as voice. However, video requires a lot more bandwidth—anywhere from 300 kbps to 10 Mbps, depending on the quality demanded. To support the QoS requirements of voice, video, and other quality or time-sensitive applications, routers and switches can be configured with a variety of QoS tools. These configurations are beyond the scope of the CCNA exam topics. Day 30 19 Study Resources For today’s exam topics, refer to the following resources for more study.
