The single server architecture of the traditional network management tool frequently has difficulty in dealing with complex network environment or multiple locations. To overcome these problems, D-View 7 is designed based on Server-Probe architecture. It consists of a server, a local probe and/or remote probe(s).
The server is the core of D-View 7 to analyze / display data and do batch configuration. It performs the following tasks:
The probe is an agent of D-View 7 to collect local device information and dispatch commands locally. A D-View 7 server comes with a built-in local probe. Remote probes can be added to monitor multiple locations.
The main tasks of a probe include:
By deploying a probe in the NAT environment, the probe discovers local networks and communicates with the D-View server without any barrier.
The communication between the server and the probe leverages either port 443 or 80, instead of many ports needed to be opened such as SNMP or Trap, which simplifies the firewall setting.
The probe in the subnet communicates with the D-View server for the devices in the subnet, reducing the WAN traffic between devices and the NMS.
