IPTDR (Internet Protocol Traffic Detail Record) in directory IPDR

Annotation: Formerly we named our hereby openly published data records IPDR as the data our traffic statistics program collects are Internet Protocol Detail Records in the meaning of the words: Detail records about Internet Protocol Network Layer. Since an organisation named IPDR.org is claims to have the abbreviation IPDR protected by a trademark "IPDR compliant (TM)", Traffic Statistics changes the wording of the Traffic Statistics Internet Protocol data record format to IPTDR as abbreviation for Internet Protocol Traffic Detail Records. Anyway it might happen, that due to technical reasons in some parts of the Traffic Statistics software or the website the string IPDR still occurs. In this case, please read it as if it would have been written IPTDR.

Please note, that Traffic Statistics does not follow the IPDR specification as published by IPDR.org nor intends to do so, because Traffic Statistics does believe that fulfilling the IPDR specification by IPDR.org would consume too much memory and CPU power, would enlarge our software to useless complexity and IPDR format from IPDR.org is probably far less popular as a standard than Cisco's NetFlow(TM) format.
