|
|
Show Understanding of Packet Switching? |
- Traditional WAN's use packet switching to inspect of address of a network packet and where to forward it to. May be series of routers between your LAN and destination LAN. |

Advantages and Characteristics of Circuit/Packet switching? |
Circuit Switching: - Gives dedicated circuit - Faster data transfer - Packets arrive in order sent - Packets cannot get lost - Better for real-time application -Potentially improved security - Dedicated video conferencing Packet switching: -Split into packets/chunks -Sends packets on individual routes - Packets may arrive out of order to delay until packet order restored -Packets may get lost so re-transmission causes delays. |
