 Big service providers (e.g. Google, Youtube, Facebook and Twitter) use a number of different hosts and hostnames to serve their content, so **PaKon has a list of domains to merge these**: ''/​usr/​share/​pakon-light/​domains_replace/''​. For example, instead of storing the hostname "​scontent.fprg2-1.fna.fbcdn.net"​ PaKon simply stores "​facebook.com"​. This means that some detail is lost. On the other hand this dramatically **improves readability of output and reduces the amount of stored data**, which is essential for a clear representation of network traffic. ​ Big service providers (e.g. Google, Youtube, Facebook and Twitter) use a number of different hosts and hostnames to serve their content, so **PaKon has a list of domains to merge these**: ''/​usr/​share/​pakon-light/​domains_replace/''​.

-The data is further reduced in order to store it longer. Most importantly,​ individual flows are aggregated. **Aggregation** simply means that instead of storing many flows of the same host, the flows are merged together for a given time frame. The total number of received and sent bytes is preserved, but some detail about duration and start times of individual flows is lost. As released in 3.9, the **records are kept for 4 weeks**, but we have plans to adjust this in the future.+The data is further reduced in order to store it longer.
