During the reported period 50 valid updates and 15 invalid updates have been received. After reception of a valid update a new international mapping table is created and archived on the file server for retrieval. The tables are also actively distributed once a month according to an agreed schedule. All four tables together contain 4'001 mapping rules . Correct mapping tables and correct function of the tools is of major concern for the Project Team.
Errors can lead to lots of routing and addressing problems immediately perceived by end users.
The Project Team handles problems if there are conflicting rules. This has not been necessary during the reported period. A reorganisation of the mapping tables for international organisations has been discussed with the Y-Net managers to ease their operation. Only one trouble ticket concerning the tables has been registered and handled by the help desk. Since the address of the Project Team is included in the two Internet RFCs defining gateway behaviour and operation, one organisation approached the Project Team to understand the mapping registry procedures and to get the tables.
