SMSC client .NET | Component Library
Component Library
Introduction
SMSC client .NET for SMPP, UCP, CIMD/CIMD2 and SEMA is a 100% managed .NET (DotNET) and COM (ActiveX/OCX) component DLL library for high performance SMS/EMS/WAP send & receive message communication through SMSC over TCP/IP. The components are designed to deliver high performance and wide range of features in communication with SMSC still guarding simplicity which allows for very quick delivery of a working solution.
Library consists of four .NET managed 32/64 bit, invisible, toolbox-installable components each implementing separate protocol (SMPP, UCP, CIMD2 and SEMA). Components can be mixed and used in multiple instances when parallel access to multiple mobile networks is required. The functionality is unified between protocols, and as a consequence the process of creating even complicated applications is simple and clear. At the same time programming interface of our components accepts set of advanced optional parameters to access low level protocol features if there is a need to.
Performance
Implementation of asynchronous mode (sliding window) and multithreading construction ensure very high performance. Our components have proven throughputs of over 500 messages per second on single TCP/IP connection.
