详细的讲述了linux的ip/tcp通信部分的协议栈，对开发很有帮助(Linux detail of the ip/tcp communication part of the protocol stack, on the development of useful)

GPRS is a communication technology that allows data acquisition systems to overcome the difficulty of cabling for wide area remote sites. GPRS applications are becoming more and more prevalent due to the ease with which they can be implemented, but the dynamic IP address issues associated with GPRS networking continue to frustrate system integrators.
