Analysis of Packet Switching
Packet switching is the transfer of small pieces of data across various networks. These data chunks or “packets” allow for faster, more efficient data transfer.
Let us see advantages and disadvantages
Advantages :
Speed : Optimal transmission speed, minimal latency.
Cost : Comparatively cost-effective and simple to implement. Packet switching typically also bills based only on duration of connectivity, whereas circuit switching bills on both duration of connection and distance.
Disadvantages :
Reliability : The packet switching process is reliable in that the destination can identify any missing packets. However, circuit switched networks deliver packets in order along the same route and are therefore less likely to experience missing packets in the first place.
Complexity : Packet switching protocols are complex, so switching nodes demand more processing power and a large amount of RAM.
File size : Packet switching is more useful for small messages, while circuit switching is best for larger transmissions. This is due to multiple rerouting delays, the risk of multiple lost packets, and other issues.
Error handling :
if one of packet is lost while transmission of all packets through different path , receiver needs to resend request for packet . Then selective packet is re send by sender or all packet from lost packet is send to receiver depending upon program written . After OS merges all packet and give to receiver .
Application of Packet switching :
- Techniques to Combat Net Radio .
- connection-oriented packet switching is in the switched WAN. Protocols like X.25, Frame-Relay, ATM .
and many more application having upgradation in Packet switching
