Question

What are the 5 mechanisms to reduce prob. and cost of losing packet?

Answer 1

There are 5 mechanisms to reduce the probability and cost of losing packets in computer networks: forward error correction (FEC), automatic repeat request (ARQ), packet loss recovery algorithms, quality of service (QoS) techniques, and duplication and redundancy of packets.

Step-by-step explanation:

Packet loss can occur in computer networks, and there are several mechanisms to reduce the probability and cost of losing packets.

1. Forward error correction (FEC) is one method used to reduce packet loss. It involves adding extra redundant data to each packet, allowing the receiver to reconstruct the missing packets if they are lost.
2. Automatic repeat request (ARQ) is another mechanism. It detects and requests retransmission of lost packets.
3. Packet loss recovery algorithms, such as selective repeat and go-back-N, can also be used to minimize the impact of packet loss.
4. Quality of Service (QoS) techniques, such as traffic prioritization and congestion control, can reduce the probability of packet loss.
5. Duplication and redundancy of packets can be employed to provide additional protection against packet loss.
