Difference between TR69 and SNMP? |
|
Answer» SNMP stands for Simple Network Management Protocol. Use of SNMP requires opening of SNMP port through NAT as most of the home gateways use NAT and the devices being managed could be behind NAT. In SNMP, the request to get/set any parameters is always initiated by the manager hence the port has to be opened on the CPE to get the request. In TR-69, a TR-69 session is initiated by CPE and the server uses the same session to send get/set requests. That does away with opening of the port explicitly in NAT environment. TR-69 also defines a way where ACS can send the request to CPE and this part is taken care by TR-111 part2 transparently. Most of the SNMP implementations existing today do not implement SNMPv3, hence the messages exchanged over SNMP is not very secure. In TR-69, the security is taken care through the SSL/TLS or HTTP based authentication schemes. Most of the TR-69 implementations as of today implement SSL/TLS. |
