Abstract: A network device may include first and second processors and a wireless transceiver under control of the second processor. The network device may further maintain one or more signatures and a wake-up module executable by the second processor. The wake up module may receive a multicast wireless communication while the first processor is in a low-power sleep mode. The wake up module may determine whether a data portion of the multicast wireless communication includes a signature. If the data portion of the wireless communication includes the signature, the wake up module may cause the first processor to leave the low-power sleep mode and process the multicast wireless communication.
Abstract translation: 网络设备可以包括第一处理器和第二处理器以及在第二处理器的控制下的无线收发器。 网络设备还可以维护一个或多个签名以及可由第二处理器执行的唤醒模块。 唤醒模块可以在第一处理器处于低功率睡眠模式的同时接收多播无线通信。 唤醒模块可以确定组播无线通信的数据部分是否包括签名。 如果无线通信的数据部分包括签名,则唤醒模块可以使第一处理器离开低功率睡眠模式并处理组播无线通信。
