| LAN Devices Four important LAN devices are (explain what each item is and how/when it is used) Repeater- device that regenerates and propagates electrical signals between two network segments - used when signal is low Bridges- filter, forward, or flood an incoming frame based on its mac address Switches- filter, forward, or flood frames based on destination addresses Routers- forward packets from network to network based on network layer info Bridges, switches, and routers can all be used to segment a LAN. What follows is a summary of how each device can be used (include the pro's and con's for each) Bridges- can only connect and segment Switches- connect multiple segments Routers- Connect multiple segments with advanced path determination Switching LAN Switching is...microsegmenting LANs using switches and the benefits include...more efficient bandwidth usage, sometimes close to 100%. The differences between Asymmetric and Symmetric Switching include: Asymmetric Switching- gives different ports on the same switch different bandwidth allocations Symmetric Switching- gives all ports on a switch the same bandwidth allocations The differences between Cut-Through and Store-and-Forward Switching are Cut-Through- the leading edge of a packet exits the output port before the tailing edge enters the input port Store-and-Forward- Entire packet is received before being forwarded Spanning Tree Protocol... enables a bridge to detect loops and shut down appropriate interfaces to end them Reflection In this lesson I learned...how to microsegment using switches. This is important to a network designer because...it is necessary to acheive best possible bandwidth. |
