Solution Description
This solution is used within the U.S.. It combines standards associated with US: NTCIP Message Sign with those for I-F: SNMPv3. The US: NTCIP Message Sign standards include upper-layer standards required to implement centre-to-field message sign communications. The I-F: SNMPv3 standards include lower-layer standards that support secure centre-to-field and field-to-field communications using simple network management protocol (SNMPv3); implementations are strongly encouraged to use the TLS for SNMP security option for this solution to ensure adeqaute security.
