Abstract: Embodiments generally provide techniques for waking up a plurality of network devices from a power saving mode via layer 1 (L1) signaling. Embodiments include entering a power saving mode at a first network device, wherein logic for processing layer 2 and higher data is inactive during the power saving mode and receiving, while the first network device is in the power saving mode, a L1 bit stream from a second network device connected to the first network device. Additionally, embodiments include, upon determining that a predefined code is present within the received L1 bit stream, exiting the power saving mode at the first network device and transmitting a second L1 bit stream containing the predefined code to a third network device.

Abstract: A method for performing packet reorder processing is disclosed. The method comprises receiving, at a packet receive buffer, a data packet, the packet receive buffer comprising a plurality of N-sized pages. The method also comprises storing the received data packet across a plurality of pages of the packet receive buffer. The method further comprises writing, at storage of each of the plurality of pages, a pointer to a next page in which a subsequent portion of the data packet is stored. The method also comprises transmitting the pointer to a ring buffer. The method further comprises calculating an offset to the ring based on a sequence number of the corresponding packet, and storing the pointer to a first page in the calculate offset of the ring buffer.

Abstract translation: 公开了一种执行分组重新排序处理的方法。 该方法包括在分组接收缓冲器处接收数据分组，所述分组接收缓冲器包括多个N个大小的页面。 该方法还包括在数据包接收缓冲器的多个页面上存储所接收的数据分组。 该方法还包括在存储多个页面中的每一个页面时写入指向下一页的指针，其中存储数据分组的后续部分。 该方法还包括将指针发送到环形缓冲器。 该方法还包括基于相应分组的序列号计算到该振铃的偏移，并将该指针存储到该环形缓冲器的计算偏移中的第一页。
