Quick start

AWS Marketplace instances

The following example adds two target SMPP servers (smsc1.smpp.org and smsc2.smpp.org) to where each customer’s SMS traffic will be load balanced.

1. SSH to your SLBP instance (or use AWS EC2 Instance Connect from your browser) as user ec2-user.

2. Add first target SMPP server:

./ec2MLSMPPLoadBalancer targetAdd smsc1 smsc1.smpp.org

3. Add second target SMPP server:

./ec2MLSMPPLoadBalancer targetAdd smsc2 smsc2.smpp.org

4. Restart the SLBP

sudo systemctl restart mlslbp

Your customers can now connect using SMPP to port 2775 on your SLBP instance. In this example, each message your customers submit will be load-balanced to smsc1.smpp.org and smsc2.smpp.org. The SMPP connections from the SLBP to each target SMSC will use the SMPP credentials provided by your customer when they bound to the SLBP.
