Embodiment Construction

[0053] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0054] figure 2 It is a schematic diagram of a network architecture provided by an embodiment of the present invention. Such as figure 2 As shown, the network architecture includes network devices (ProviCnnM Edge, PE) XE1 and XE3 deployed at the edge side, and network device (ProviCnnM, P) XE2 deployed at a middle location. Wherein, the client device is connected to the network device PE at the sending end, and transmits the generated client service (data flow) to the network device PE at the receiving end through the network device PE at the sending end and one or more network devices P. In some cases, there may be no network device P in the network. The embodiment of the present invention can be applied to X-Ethernet, Ethernet, FlexE, IP net...

Abstract

The present application provides a method, network device and system for sending and receiving detection blocks, wherein the method for sending detection blocks includes: the network device obtains an original bit block data stream; generates at least one detection block, and inserts the at least one detection block into the position of at least one free block in the original bit block data stream; sending a bit block data stream containing the at least one detected block. In the present application, the detection block transmission is performed by occupying the bandwidth resources of the free blocks in the bit block data stream, thereby solving the problem of the loss of the bit block of the service.

Description

technical field [0001] The present application relates to the communication field, and in particular to a method, network device and system for detecting block transmission and reception. Background technique [0002] Currently, an interface technology of a Flex Ethernet implementation agreement (Flex Ethernet implementation agreement 1.0, FlexE IA 1.0) has been standardized in an optical internetworking forum (OIF). Flexible Ethernet (Flex Ethernet, FlexE) interface technology can be applied to data center equipment interconnection, etc., by binding n 100G physical layer devices (physical layer device, PHY) to transmit multiple channels of FlexE customer services with different rates. In the future, FlexE will also define switching technology, L1.5 layer switching technology, also known as X-Ethernet switching technology or X-E switching technology. L1.5 layer switching technology (i.e. X-Ethernet switching technology or X-E switching technology), is a bit block (for examp...
