Hello,
Just wanted to add that in our TCP/IP implementation, the instance identifies an endpoint to a network management application. We created a proprietary SNMP table that augments udpEndpointEntry, so we could provide counter statistics (datagrams, octets) for the endpoints. So if a management app is polling the UDP endpoint information, it uses the instance to recognize updated counters for an endpoint. We increment the instance value for each new endpoint.
