Comprehensive Network Latency & Jitter Analysis Report — Target: Google DNS (8.8.8.8)
Executive Summary
A controlled network performance test was conducted using a Ping Jitter Calculator to evaluate latency stability, jitter variation, and throughput efficiency between the local host and Google Public DNS (8.8.8.8).
The test ran 50 ping samples using 64-byte packets sent at 0.2-second intervals. The results indicated an average latency of 11.26 ms, maximum latency of 20.37 ms, and minimum latency of 5.90 ms, yielding a jitter measurement of 2.01 ms, which classifies as Excellent network stability.
This suggests the network is performing near optimal conditions, with negligible packet delay variance — a key metric for real-time operations such as voice communication, live streaming, gaming, or critical data transmission.
1. Test Configuration and Sampling Explanation
1.1 DNS Target Selection
The test tool offered five DNS endpoints:
Option | Target IP | Provider | Purpose |
|---|---|---|---|
1 | 8.8.8.8 | Google DNS | Global standard, highly distributed; ideal for benchmarking. |
2 | 1.1.1.1 | Cloudflare DNS | Known for low latency and strong privacy. |
3 | 9.9.9.9 | Quad9 DNS | Security-oriented resolver with threat filtering. |
4 | 208.67.222.222 | OpenDNS | Enterprise-grade DNS by Cisco; stable routing paths. |
5 | Custom | User-defined | Useful for testing specific network endpoints (e.g., internal DNS, VPN gateway). |
Chosen target: 8.8.8.8 — a reliable, redundant public endpoint suitable for consistent global latency testing.
1.2 Packet Size Options
Option | Packet Size | Description |
|---|---|---|
1 | 64 bytes | Standard ICMP packet size — ideal for raw latency measurement. |
2 | 128 bytes | Adds moderate payload; tests small-packet consistency. |
3 | 512 bytes | Begins stressing MTU and buffer handling. |
4 | 1024 bytes | Larger payload, simulates application-level packets. |
5 | Custom | User-defined for MTU or QoS boundary tests. |
Chosen packet size: 64 bytes — ensuring a pure latency test without introducing payload-induced delay or fragmentation effects.
1.3 Ping Interval Options
Option | Interval (seconds) | Purpose |
|---|---|---|
1 | 0.2 | High-frequency sampling; detects micro-latency and jitter spikes. |
2 | 0.5 | Balanced sample interval for general testing. |
3 | 1.0 | Default ICMP test rate for many diagnostic utilities. |
4 | 2.0 | Low-frequency monitoring, reduces congestion during long tests. |
5 | Custom | User-defined; supports stress or endurance testing. |
Chosen interval: 0.2 seconds — enables precise observation of micro-variations in latency.
1.4 Sample Count and Duration
Ping Count: 50 samples
Total Duration: 50 × 0.2s = ~10 seconds
This provides a compact but statistically relevant dataset for measuring standard deviation, average, and jitter.
Larger sample sets (e.g., 200–500) would improve long-term stability analysis but are unnecessary for instantaneous performance diagnostics.
2. Results Interpretation
Metric | Result | Technical Interpretation |
|---|---|---|
Average Ping Time | 11.26 ms | Excellent latency typical of high-speed fiber or low-load broadband. |
Minimum Ping Time | 5.90 ms | Indicates best-case scenario with no queue delay or retransmission. |
Maximum Ping Time | 20.37 ms | Slight increase likely due to routing load or background processes; still low. |
Standard Deviation | 2.03 ms | Very stable connection; low dispersion from mean latency. |
Jitter | 2.01 ms | Outstanding consistency — jitter under 5 ms is ideal for all real-time uses. |
Download Speed | 770.77 Mbps | Reflects strong downstream capability — typical of gigabit-class service. |
Upload Speed | 37.27 Mbps | Sufficient for most applications, though lower than download, typical of asymmetric consumer-grade links. |
Ping (Speed Test) | 15.17 ms | Validates ICMP results; minimal variance indicates consistent routing. |
Classification | Excellent | Connection is highly stable and responsive. |
3. Alternative Result Scenarios
Scenario | Possible Result | Technical Meaning | Corrective Action |
|---|---|---|---|
High Jitter (>30 ms) | Large variation between pings | Indicates congestion, queuing, or unstable routing | Check local load, QoS settings, and ISP congestion. |
High Average Latency (>100 ms) | Consistently slow response | Could mean distance to target or network overload | Try a geographically closer DNS server or route analysis (traceroute). |
Low Download Speed (<100 Mbps) | Bottleneck observed | May reflect shared bandwidth, throttling, or hardware limits | Test directly via Ethernet; avoid Wi-Fi interference. |
High Upload Speed, Low Download Speed | Asymmetric performance | Possible misconfiguration or provider-side shaping | Verify MTU, QoS, and DNS preference. |
Jitter <1 ms | Extremely stable | Represents enterprise-grade fiber backbone quality | No action — optimal performance. |
4. Comparative Host Behavior (Optional Reference)
DNS Host | Expected Avg Latency (North America) | Expected Jitter | Comments |
|---|---|---|---|
8.8.8.8 (Google) | 8–15 ms | 1–3 ms | Balanced, globally cached routing. |
1.1.1.1 (Cloudflare) | 6–12 ms | 1–2 ms | Often the lowest latency in urban areas. |
9.9.9.9 (Quad9) | 10–20 ms | 2–4 ms | May vary slightly depending on peering. |
208.67.222.222 (OpenDNS) | 12–25 ms | 3–6 ms | Reliable but slightly higher due to Cisco peering routes. |
Your 8.8.8.8 results are consistent with top-tier expected performance.
5. Technical Conclusions
The test demonstrates a highly optimized, low-latency network with negligible jitter and sufficient throughput to support data-intensive and latency-critical operations.
Key conclusions:
Latency and jitter values fall within professional-grade thresholds.
No evidence of congestion, queue delay, or packet instability.
Download bandwidth indicates strong backhaul performance, while the upload rate suggests standard asymmetric provisioning.
Network is suitable for real-time services: VoIP, telepresence, streaming, remote workstations, and VPN applications.
The test conditions (64-byte packet, 0.2-second interval, 50 samples) produced a concise and reliable snapshot — optimal for mid-range diagnostics without overwhelming the channel.
Recommendations
Conduct extended tests (100–500 pings) for long-term variance trends.
Run comparative tests with 1.1.1.1 (Cloudflare) and 9.9.9.9 (Quad9) for route diversity.
Repeat during peak network hours (evening) to observe congestion impact.
For throughput validation, confirm via iPerf3 or equivalent utility under controlled conditions.
Final Classification:
Network Quality: Excellent
Latency Stability: Outstanding
Operational Readiness: 100% for Real-Time and Critical Systems
