Abstract:
A method for providing address translation for a plurality of packets received in a network system, the method comprising the steps of:performing network address translation operations on at least a subset of the packets; identifying particular ones of the translated packets as being associated with a designated network management protocol; parsing the identified network management protocol packets to determine if the payload of a given one of the network management protocol packets contains additional address information requiring further translation, wherein the parsing step as applied to the given network management protocol packet parses the payload of that packet to identify if any of a plurality of different object types are present in the payload, the plurality of different object types comprising at least an address object type, an object identifier object type, and a sequence indicator object type; and applying an additional translation operation to the additional address information of at least one of the identified network management protocol packets as determined in the parsing step, such that the packets are thereby provided with non-conflicting address spaces.
