Operational Requirements

Clients must follow these operational requirements when connecting to the service via SMPP:

  • Have sufficient number of binds to support 100% of client traffic.
  • Make sure that the field with the SMPP gateway addresses is configurable. The SMPP gateway address changes on rare occasions.
  • Make sure that application code is pointing to the provided SMPP gateway addresses and not the IP address.
  • Avoid white listing the gateway addresses by IP on any device residing on the client application's path to the Internet.
  • Have automatic failover logic in place to reroute traffic to active binds available at any given time.
  • Use a send-window not exceeding 20
  • Implement Transport Layer Security (TLS) v 1.2 or 1.3 encryption for all SMPP communication.
