Address Translation in the ISS Network

NETRIX Performs Translations

The Netrix network performs network translation through the use of a simple, yet powerful, translation language to build a set of translation rules. Each line in the box below is a rule.

Address Translation Flow

Addresses are tested to see if they match the coding in one of the rules.

If the is no match, the address is tested against the next rule.

If a match is found, the address is translated as indicated in the rule.

The simple process shown above took an incoming address of 846211 and changed it to 46211 (dropping the first digit '8'). We will explain this translation process in more detail in the rest of this course.
