System Requirements for Yeastar Load Balancer (Required Only for High Availability)

Yeastar provides a dedicated Load Balancer to enable high availability for SBC servers in environments that do not offer native load balancing services. This topic describes the requirements for deploying Yeastar Load Balancer.

Note:
  • This topic applies only to deployments that require high availability. If high availability is not needed, you can skip this topic.
  • The private subnet of the server MUST be set to one of the following subnet options, otherwise the server installation would fail.
    • 10.0.0.0/8
    • 172.16.0.0/12 (excluding the 172.17.x.x and 172.19.x.x IP address ranges)
    • 192.168.0.0/16

Deployment environment requirement

To deploy the Yeastar Load Balancer, ensure the following environment conditions are met:

Item Requirement
Firmware

To work properly with the Yeastar Load Balancer, the following servers must be running the required firmware versions.

  • YCM Server: 87.15.0.24 or later
  • SBC Server / SBC Proxy Server: 86.15.0.70 or later
  • PBXHub Server: 85.15.0.36 or later
Network The Load Balancer and SBC servers must reside in the same subnet to ensure seamless traffic flow.
Routing function Policy-based routing can be configured between the load balancer and SBC servers to ensure proper traffic forwarding and failover handling.

Hardware requirement

The server hosting the Yeastar Load Balancer should meet the following minimum requirements.

Item Requirement
CPU Intel brand, 4 vCPU (thread), 3 GHz
Memory 8 GB
Storage 200 GB
Important: Minimum 150MB/s read speed and 150MB/s write speed.

Operating system requirement

Item Requirement
Version Ubuntu 24.04 LTS (64-bit)
Note: For proper functioning of the server, a standard Ubuntu installation is required. Minimal installation is NOT recommended.
Language English
Important: The default operating system language MUST be set to English to ensure the proper operation of the server.

Ethernet port requirement

The Yeastar Load Balancer needs 1 Ethernet port.

Network bandwidth requirement

To ensure smooth call signaling and media traffic forwarding, the network bandwidth of the server running the Yeastar Load Balancer must scale with the supported number of extensions in the system.

Numbers of Extensions Minimum Upstream/Downstream Bandwidth
10,000 60 Mbps
40,000 240 Mbps
60,000 360 Mbps
80,000 480 Mbps
