Configuring Relay Agents

In larger networks you may experience increased network bandwidth use due to the amount of data transferred from the GFI LanGuard server to managed computers. The data consists of definition updates delivered to Agent computers and of patches being deployed to target computers.

To help avoid performance issues and to apply load balancing techniques, GFI LanGuard enables you to configure Agents as a relay of the server. Agents that are configured as Relay Agents act as caching points. These download patches and definitions directly from GFI LanGuard server or from an upstream Relay Agent and forward them to client computers (which can be Agent-based and Agent-less computers). The main advantages of using Relay Agents are:

  • Reduced bandwidth consumption in local or geographically distributed networks. If a Relay Agent is configured on each site, a patch is only downloaded once and distributed to client computers
  • Reduced hardware load from the GFI LanGuard server component and distributed amongst relay agents
  • Using multiple Relay Agents increases the number of devices that can be protected simultaneously.

Follow the below recommendations to take full advantage of Relay Agents:

  1. Keep the number of computers/agents directly connected to the GFI LanGuard server or to one Relay Agent below 100.
  2. In geographically distributed networks, designate at least one Relay Agent for each remote site. This ensures that each file is only transmitted once from the GFI LanGuard server site to the remote site.
  3. Fine-tune network use by configuring cascading Relay Agents
