SMPP Session and Connection Handling

This section includes the classes responsible for managing the lifecycle, state, and behavior of SMPP sessions and underlying network connections. These components abstract the complexities of session control, binding, message routing, and channel-level operations between ESMEs and the SMSC.

Interfaces like SmppSession, SmppServerSession, and their implementation SmppSessionImpl manage bind/unbind operations, session state transitions, and protocol negotiation (e.g., version, capabilities).
