# Analysis and Prediction of the IPv6 Traffic over Campus Networks in Shanghai
## 3 Dataset and Traffic Usage Features
### Traffic Patterns of Weekdays and Weekends  
There are apparent differences in average downstream traffic volume between weekdays and weekends. The average IPv6 traffic volume of DHU on weekdays is 320.5 Mbps, while the average traffic volume on weekends is 203.7 Mbps. The average weekday IPv6 traffic volume of ECNU is 114.0 Mbps, while the average traffic volume during weekends is 84.5 Mbps. In both universities, the IPv6 network traffic usage on weekdays is higher than that on weekends. IPv6 downstream traffic patterns of weekdays and weekends are

For DHU, the IPv6 network traffic volume on weekdays ranges from 18.7 Mbps (average) from 04:00 to 06:00 CST to 653.0 Mbps (average) from 14:00 to 16:00 CST. The pattern is similar on weekends but lower, with a minimum of 15.0 Mbps and a maximum of 409.0 Mbps. In ECNU, the IPv6 network traffic volume on weekdays ranges from 23.1 Mbps (average) from 00:00 to 02:00 CST to 216.4 Mbps (average) from 14:00 to 16:00 CST. On weekends, the pattern is different as the IPv6 network traffic volume ranges from 23.1 Mbps (average) from 06:00 to 08:00 CST to 158.0 Mbps (average) from 14:00 to 16:00 CST. The proportion of IPv6 downstream network traffic volume to total downstream network traffic volume also differs between weekdays and weekends. For DHU, the percentage of IPv6 network traffic volume on weekdays ranges from an average of 43.3% from 04:00 to 06:00 CST to 64.8% from 20:00 to 22:00 CST. On weekends, the pattern is different as the percentage of IPv6 network traffic volume ranges from an average of 39.3% from 06:00 to 08:00 CST to 63.5% from 14:00 to 16:00 CST. In ECNU, the percentage of IPv6 network traffic volume on weekdays ranges from an average of 5.3% from 00:00 to 02:00 CST to 8.6% from 04:00 to 06:00 CST. The pattern is similar on weekends but with a lower minimum of 5.2% and a higher maximum of 11.0%. For the upstream network traffic, the average IPv6 traffic volume of DHU on weekdays is 32.2 Mbps, while the average traffic volume on weekends is 23.4 Mbps. The average

(**b**) Downstream traffic patterns in ECNU. weekday IPv6 traffic volume of ECNU is 16.5 Mbps, while the average traffic volume during weekends is 16.0 Mbps. In both universities, the IPv6 upstream network traffic usage on weekdays is higher than that on weekends. IPv6 upstream traffic patterns of weekdays and weekends are shown in Figure 4. For DHU, the IPv6 network traffic volume on weekdays ranges from an average of 6.5 Mbps from 04:00 to 06:00 CST to 57.7 Mbps from 14:00 to 16:00 CST. On weekends, the pattern is different as the IPv6 network traffic volume ranges from an average of 5.8 Mbps from 04:00 to 06:00 CST to 40.8 Mbps from 18:00 to 20:00 CST. In ECNU, the IPv6 network traffic volume on weekdays ranges from an average of 2.6 Mbps from 04:00 to 06:00 CST to 27.0 Mbps from 14:00 to 16:00 CST. On weekends, the pattern is different as the IPv6 network traffic volume ranges from an average of 3.0 Mbps from 04:00 to 06:00 CST to 27.3 Mbps from 16:00 to 18:00 CST. The proportion of IPv6 upstream network traffic volume to total upstream network traffic volume also differs between weekdays and weekends. For DHU, the percentage of IPv6 network traffic volume on weekdays ranges from an average of 18.5% from 00:00 to 02:00 CST to 29.8% Mbps from 14:00 to 16:00 CST. On weekends, the pattern is different as the percentage of IPv6 network traffic volume ranges from an average of 15.9% from 00:00 to 02:00 CST to 28.0% from 18:00 to 20:00 CST. In ECNU, the percentage of IPv6 network traffic volume on weekdays ranges from an average of 2.2% from 04:00 to 06:00 CST to 3.7% from 14:00 to 16:00 CST. On
