    • In a communication system, a first communication apparatus includes: an application data generating unit for generating application data including data at an application level and a priority at the application level; and a lower-level packet generating unit disposed therein for generating a packet by adding to the application data a header including a destination address and a source address at a level lower than the application level. A first relay apparatus includes: a priority identifying unit disposed therein for determining whether or not a priority is set in the application data of the packet received by the first relay apparatus, and thereby identifying a first priority at the application level; and a priority control unit disposed therein for renewing a TOS field value in the header of the packet, the header being at the level lower than the application level, on the basis of the first priority.
    • 在通信系统中,第一通信装置包括:应用数据生成单元,用于生成包括应用级的数据和应用层的优先级的应用数据; 以及其中设置的低级分组产生单元,用于通过向应用数据添加包括目的地地址和低于应用级别的源地址的报头来生成分组。 第一中继装置包括:优先级识别单元,其设置在其中,用于确定在第一中继装置接收到的分组的应用数据中是否设置了优先级,从而在应用级别识别第一优先级; 以及设置在其中的优先级控制单元,用于基于所述第一优先级更新所述分组的报头中的TOS字段值,所述报头位于比所述应用级别低的水平。
