Key Network Performance Metrics | Generated by AI

Question: To research and use computer networks, one must first have a set of criteria to evaluate how well a network is performing ().

Answer:

The correct answer is 性能指标 (performance indicators / performance metrics).

Explanation:

When studying or working with computer networks, the most fundamental way to judge whether a network is “good” or “bad” is through a systematic set of performance indicators (性能指标体系).

These indicators are generally divided into two main categories:

  1. Quantitative performance metrics (定量指标) – can be measured numerically
    Common examples include:
    • Rate / bandwidth (速率 / 带宽)
    • Delay / latency (时延)
    • Delay variation / jitter (时延抖动)
    • Throughput (吞吐量)
    • Packet loss rate (丢包率)
    • Error rate (误码率)
    • Availability (可用性)
    • Reliability (可靠性)
  2. Qualitative / non-quantitative performance aspects (非定量指标)
    These are more subjective or harder to express purely in numbers, such as:
    • Ease of use
    • Scalability
    • Security
    • Manageability
    • Cost-effectiveness
    • Compatibility

Therefore, the complete and standard fill-in-the-blank answer for this question is 性能指标.
