可靠性在数字无线电点对点系统的传输中是非常关键的，尤其是批量数据在窄带中的传输。针对目前大多数的应用都是基于不可靠的用户数据报协议 UDP(User Datagram Protocol)，提出了精简可靠 R2 UDP协议(Reduced Reliable UDP)，协议中创新地提出了可选择捆绑确认帧 SBACK (Selective Bundled Acknowl-edgement)和智能探测帧(smart probe)。实验表明 R2 UDP协议能有效地改善传输效率并节约带宽，而且也减少了批量数据对共享信道传输的影响。

Reliability is very important in digital radio point to point transmission system,especially for bulk data transfer in narrow band channel.Aiming at the fact that current most applications are based on raw UDP service which does not guarantee the reliability,the article presents R2UDP(Reduced Reliable UDP )over the air transfer suitable to radio system,SBACK(selective bundled ACK)and smart probe improves the transfer efficiency and saves the band-width,and also minimizes the impact of bulk data transfer to other traffic on the shared channel.
