transmission priority

Background: AIDS epidemics and infection is on the rise in China, the bridge population bonds the normal population to the high-risks, block the transmission in bridge population is becoming the priority in AIDS epidemic control and prevention.

背景：我国艾滋病感染状况和流行形势日趋严重，桥梁人群正在使HIV从高危人群向一般人群播散，阻断桥梁人群传播艾滋病的方法和措施研究已成为控制HIV流行的优先领域。

Wideband network systems protocol stack includes physical layer, data link layer, network layer and application layer. The data link layer mainly completes multiple access, priority queues, data segmentation and reassembly, reliable transmission and other functions.

宽带网络系统协议栈分为物理层、数据链路层、网络层以及应用层，数据链路层主要完成多址接入、优先级队列、数据分段及重组、可靠传输等功能。

This paper introduces that a real time transmission of some low priority stations can be guaranteed in CAN field bus control network.

介绍在CAN现场总线控制网络中保证优先级较低站点数据传输实时性的有效方法。
