SMAL是short message abstract library的缩写,是由风起水流软件工作室（www.zealware.com）开发的一个支持短信网关系统开发的C++底层抽象接口库，通过对移动、联通、网通、电信等运营商使用的各种短信协议和底层通信的抽象封装，SMAL实现了一个高度自适应的短信协议栈，包括CMPP，SGIP，SMPP，SMGP，CNGP，EMPP等短信协议，同时可以很方便地在上面扩展实现新的协议和自定义的内部协议等。 SMAL目前支持的协议包括中国移动的CMPP2.0,CMPP3.0,中国联通的 SGIP1.2, SGIP1.2修订版，中国电信的SMGP2.0，SMGP3.0，中国网通的CNGP2.0，和国际标准SMPP3.3，SMPP3.4，以及企信通协议EMPP等。(SMAL is a short message abstract library acronym by wind currents from studio software (www.zealware.com) to develop a support system developed by SMS Gateway C++ Underlying abstract interface library, through the Mobile, Unicom, Netcom and telecommunications operators using a variety of messaging protocols and the bottom of the abstract communications package, SMAL achieve a highly adaptive messaging protocol stack, including the CMPP, SGIP, SMPP, SMGP, CNGP, EMPP such as SMS agreement, at the same time can be easily above the realization of the new agreement to expand and customize the internal agreement. SMAL currently supports the agreement, including China Mobile CMPP2.0, CMPP3.0, China Unicom SGIP1.2, SGIP1.2 revised edition, China Telecom SMGP2.0, SMGP3.0, China Netcom CNGP2.0, and international Standard SMPP3.3, SMPP3.4, as well as enterprises, such as ICT EMPP agreement.)
