Some 10+ years ago, SNMP decoupled the identity of an SNMP service from the transport used to access the service by introducing the notion of an engineID. It was architecturally the right thing to do. At that time, people hoped that management applications would at start using engineIDs since they are architecturally the right thing to deal with proxies, NATs and all sort of issues. Ten years later, we must simply observe that this did not happen. Perhaps HIP as a more general solution to this problem has more luck. /js -- Juergen Schoenwaelder Jacobs University Bremen gGmbH Phone: +49 421 200 3587 Campus Ring 1, 28759 Bremen, Germany Fax: +49 421 200 3103 <http://www.jacobs-university.de/>
