Arbitrated loop address management apparatus method and system
First Claim
1. An apparatus for managing messaging in an arbitrated loop network, the apparatus comprising:
- an address map configured to associate desired addresses with assigned addresses; and
an address assignment monitor configured to monitor an address assignment process in an arbitrated loop network and populate the address map;
a switching array configured to route packets to devices attached to the arbitrated loop network using the address map.

Abstract
An apparatus, system, and method are disclosed for automatically and transparently managing addresses in an arbitrated loop network. An arbitrated loop network switch is programmed with an address map and configured with the necessary modules to monitor an address assignment process and associate soft assigned addresses claimed during the address arbitration process with physical slot addresses. In one embodiment, the address fields of packets addressing a specific physical slot are changed (in route) to the soft address assigned during the address arbitration process. The entire process may be transparent to the rest of the network and to users. The present invention facilitates maintaining a physically ordered addressing scheme despite any soft addressing that occurs during loop initialization.
