摘　　要：针对现有SIP服务器成本高、功耗大、稳定性低的缺点,设计一个能为SIP终端之间通信提供服务的嵌入式SIP服务器。系统采用ARM Cortex-A8内核的Samsung S5PV210处理器和嵌入式Linux操作系统,设计底层SIP协议栈,实现SIP服务器的注册、代理和重定向功能,并采用基于重定向的负载均衡技术来保证嵌入式SIP服务器在高负载情况下的处理效率。经过实测实验,该系统能为SIP终端之间通信提供服务,具有实时性好、功耗低、可靠性高的特点。Aiming at the disadvantages of high cost, high power consumption and low stability of current SIP server, we designed an embedded SIP server which can provide services for the communication between SIP terminals. The system uses Samsung SSPV210 processor with ARM Cortex-A8 kernel and the embedded Linux operating system. In this system,, we designed the underlying SIP protocol stack, and implemented the functions of SIP server including registration, proxy and redirection. Moreover, we employed the redirection-based load balancing technology to ensure the processing efficiency of the embedded SIP server under high load conditions. Through measured experiments, the system can provide services for the communication between SIP terminals, and has the advantages of good real-time property, low power consumption and high reliability.
