## Broadcaster Installation Process

### Launch and Configure EC2 Instance

- Launch an EC2 instance with the recommended specifications 
- Attach the instance to your VPC and subnet 
- Allocate a static IPv4 address 
- Attach a second NIC from the same subnet. This is critical for DPDK to run successfully.

NIC 1 (Index 0): Control and management traffic 

NIC 2 (Index 1): Dedicated DPDK traffic

### Initial System Verification

- SSH into the EC2 Instance
- Install the Broadcaster
- Log into the Broadcaster 
- Navigate to Settings -> Network 
- Verify you see 2 NICS listed with static IPV4 addresses. Gateway can be empty.
- Driver shows as ena for both interfaces.

- In your SSH Terminal window navigate to the Zixi install directory and run
  - sudo ./dpdk-install.sh
  - The script will: 
    - Download and compile DPDK libraries 
    - Configure huge pages 
    - Set up CPU affinity 
    - Install necessary kernel modules 
    - Configure system parameters 
  - Green text indicates a successful installation - see screenshot below.

### Enable DPDK in Zixi Broadcaster

- Restart the broadcaster from the Main Dashboard 
- Reload the Network -> Settings page
- Click "Enable DPDK" on the Network Settings screen

### Configure Server Ports for DPDK

- Navigate to **Settings → General** 
- In the **Server Ports** section, for each port: 
  - Select the **IP for DPDK** from the IP dropdown list 
  - ![Screenshot: IP dropdown list](https://app.archbee.com/api/optimize/amUtKWPrNQCS-26DKyGuI-yzXrtMdVCDuCM5Bs5Tssz-20250408-175254.png "Screenshot: IP dropdown list")
  - This will be the IP of your second NIC 
- **Restart the Broadcaster** from Main Dashboard

### Verify DPDK Successful Installation

- On the Main Status Dashboard in the Broadcaster the 2nd NIC should be blue, which indicates DPDK is running.

- In "Statistics" for the DPDK Nic (2nd NIC) the data should be increasing indicating the stream traffic is flowing. If it is empty there is an issue.

- In the SSH terminal you will see the same \<NIC name> with \_mirror suffix
