Show Understanding of Circuit Switching and where it is used? |
- Similar to a phone network. A dedicated circuit between 2 network devices. Provides privacy and full use of bandwidth between those devices. - Expensive and example used in is Video conferencing. |
|
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. |
|
Understanding function of Router in Packet Switching? |
- Task of hardware router is to receive data packets from a packet-switched network and then route packet towards it destination address. - Router maintains routing tables to suggest best possible paths to destination IP address. -Packet can be re-directed many times before reaching it's destination. |

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. |
