More engineering. Less paperwork. Expenses made simple.
Overview
Efficient, scalable, rock-solid, and flexible Java implementation of the Short Messaging Peer to Peer Protocol (SMPP).
Twitter exclusively relies on this library for its global SMS infrastructure.
- Real-world used library by Twitter across nearly every SMSC vendor and mobile operator around the world. We've seen almost every variance in the SMPP protocol and this library handles it flawlessly.
- Rigorous unit testing
- Support for SMPP protocol:
- Version 3.3
- Version 3.4
- Most of version 5.0
- Uses non-blocking (NIO) sockets (via underlying Netty dependency, one thread can support 1 or more SMPP sessions)
- Can support thousands of binds/connections using minimal resources and threads
- Supports both client and server modes of the SMPP protocol (yes you can write your own SMPP server using this library as well as be a client to one)
- Supports synchronous request mode (send request and block until response received)
- Supports asynchronous request mode (send request, get a future response, and then decide when you'd like to wait/get a response)
- Advanced support for SMPP "windowing":
- Configurable window size per session
- Waiting for a window slot to open up
- Get a list of unacknowledged/in-flight PDUs if session disconnects
- SSL/TLS support for clients and servers
- Configurable support for expiry of unacknowledged PDUs
- Configurable counter metrics per client-session, server-session, or server.
- Support for sniffing/logging/discarding of PDUs before normal processing
The library has been tested and certified with hundreds of mobile operators and suppliers around the world. It's effective at being flexible with SMPP specifications that aren't truly compliant.
Background and Contributors
This library was originally developed by Cloudhopper, Inc. in 2008. Cloudhopper was acquired by Twitter in April 2010. The main author of this library, Joe Lauer, left Twitter in April 2013 to found Fizzed, Inc. As of Nov 2015, Fizzed, Inc is the official maintainer of the library. If you're looking for commercial support, please contact Fizzed.

Installation
Library is available via maven central. For netty-3 and a stable version:
<dependency>
<groupId>com.fizzed</groupId>
<artifactId>ch-smpp</artifactId>
<version>5.0.9</version>
</dependency>
For netty-4 and a little more bleeding edge. Visit netty-4 branch
<dependency>

<artifactId>ch-smpp</artifactId>
<version>6.0.0-netty4-beta-3</version>
</dependency>
Demo Code / Tutorials
There are numerous examples of how to use various parts of this library:
src/test/java/com/cloudhopper/smpp/demo/
To run some of the samples, there is a Makefile to simplify the syntax required by Maven:
make client
make server
make performance-client
make simulator
make rebind
make parser
make dlr
make ssl-client
make ssl-server
make persist-client
make server-echo
On Windows, the examples can run with nmake instead of make.
The easiest way to get started is to try out our server and client or ssl-server and ssl-client examples. Open up two shells. In the first shell, run:
make server
In the second shell, run:
make client
You'll see the client bind to the server and a few different type of requests exchanged back and forth.
You can also try make persist-client instead of make client which demonstrates a persistent SMPP connection.
make server-echo will echo back any MT as an MO. This makes it easier to test handling of MO messages.
