Traffic Among Servers

In modern IS/IT infrastructures, servers are typically grouped together in server farms, which need to be physically secured with access restricted to authorized personnel. This ensures that server traffic remains within the physical locations where servers are stored. Layer-2 and Layer-3 network devices are also located in these areas, helping to maintain the physical separation of server traffic from other network traffic. To further protect server-to-server traffic, it is recommended to set up a specific VLAN for grouping servers. For more details, see MiVoice MX-ONE Architecture. If servers are located remotely, it is highly recommended to establish a Virtual Private Network (VPN) system and firewalls to protect and monitor communication between them. Additionally, if SIP trunks are used, consider protecting them with a VPN.
