─ DVR Name Service (DVRNS)
Overview
Using Static IP addresses in LAN/WAN networks requires high management overhead and increases the cost burden to
users. Therefore, it has become essential for DVRs to support Dynamic IP addresses in ADSL/VDSL networks using
DHCP (Dynamic Host Configuration Protocol). This reduces cost burdens and increases cost effectiveness for system
users. Use the following steps to set up a system using DVRNS.
System Configuration
STEP 1 (DVR Æ DVRNS Server): Register the unit name and IP address of the DVR during the DVRNS setup on
the Remote DVR. This unit name and IP address will be registered on the DVRNS server directly.
NOTE: Refer to the applicable manual for each remote DVR for more details on DVRNS setup.
STEP 2 (RASplus
Æ DVRNS Server): Request the IP address of the remote DVR using the registered unit name
of the DVR you want to connect to.
STEP 3 (DVRNS Server
Æ RASplus): The DVRNS server notifies RASplus of the requested IP address.
STEP 4 (RASplus
Æ DVR): Connect to the target DVR using the IP address returned from the DVRNS server.
NOTE: You should follow steps 2 to 4 whenever connecting to the remote site because the DVR name and IP
address might change at anytime.
