Basically, since no existing protocol was suggested and so we will be stuck with developing our own one for interaction between network-enabled GPS unit and the server, we will use SOAP and HTTP authentication scheme. In HTTP authentication we can use text string as login that is some unique GPS id (at least in the scope of given server). Since it looks like no global GPS unit MAC/id already exists, we need some authority that can control the process of assignment of such ids if we want them to be globally unique. Our another way it's possible to adopt some existing identifier authority for those purposes. Application enterprise numbers assigned by IANA for purposes of LDAP, SNMP and maybe some other protocols comes to mind. I think that it should be possible to use IANA assigned numbers for this. Everyone, who want to develop such network-enabled GPS unit, will have to request a number in IANA and then assign numbers for each unit within it's own namespace he got from IANA. That will work just like MAC addresses work. But, can someone advocate the necessity of using globally unique ids for units? At this time, we think about just letting user gonfigure any login/password pair on the device and than register it on the server. -- Anton Martchukov http://www.martchukov.com 0xFC4FBF28 96BC 3DAB 231A 7FCC 4F49 D783 9A69 65C1 FC4F BF28
