Scalable Architecture InterMapper's sub-maps can be hosted on InterMapper servers at remote locations. This allows managers of large networks to distribute the monitoring effort across several InterMapper servers. This has a number of advantages: Decreased network traffic by keeping most monitoring traffic local to a site. For example, if a company had a central office and three branch offices, it could install an InterMapper at each office. Each office's InterMapper would monitor the local network, and the central office's map could show a summary of the branch office status on a top-level map. Local and/or Global Responsibility InterMapper allows the central network administrator to grant access rights to the branch office staff or not, as the policy dictates. Full Visibility The central office staff can see any of the sub-maps from the branch office simply by using InterMapper Remote. A double-click opens the submap to show the full details. Remote Administration of InterMapper The central staff can also configure any of the branch office maps using InterMapper Remote. Maintain Security Even when there are firewalls and/or VPNs between the offices, InterMapper's sub-maps still provide full details to the network manager. The firewall can be configured to allow InterMapper's traffic through a user-selected port for the communication between the servers.
