Abstract

The present application provides a method for isolating and recovering after a failure of one or more physical layer devices PHY in a FlexE group and a network device. The method includes: the network device determines that the first overhead block corresponding to each currently available PHY is stored in the corresponding memory, then determines that the FlexE group meets the PHY alignment condition, and starts reading cached data from each memory at the same time . Therefore, there is no need to insert local fault LF code blocks for all client clients, and there is no need to regroup. It effectively reduces the impact of the faulty PHY on the customer service carried by the normal PHY. In addition, by setting the slow read mechanism of the memory, the delay change caused by the faulty PHY is effectively absorbed, and there is no need to re-execute the PHY alignment operation, and the non-destructive fault recovery of the PHY is realized.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a flexible Ethernet (English: Flexible Ethernet, FlexE) communication method, network equipment and system. Background technique [0002] FlexE technology is a low-cost, highly reliable carrier-class interface technology based on high-speed Ethernet (English: Ethernet) interface and decoupling the Ethernet media access control (English: Media Access Control, MAC) layer from the physical layer. The FlexE technology realizes the decoupling of the MAC layer and the physical layer by introducing a flexible Ethernet shim (English: FlexE shim) layer on the basis of IEEE802.3, thus realizing flexible rate matching. [0003] The FlexE technology meets the port application requirements of flexible bandwidth by binding multiple Ethernet physical layer devices (hereinafter referred to as PHY) into a flexible Ethernet group (English: FlexE group) and physical layer channe...
