The present application provides a method for receiving a code block stream and a communication device, the method comprising: the receiving device receives a code block stream of a first rate mode including a plurality of code blocks from a transmission network; the receiving device receives from the code block stream determining a target code block, wherein the target code block is a code block received by the receiving device within a packet gap of the code block stream, the target code block includes a first target code block, and the first target code block is a data type code block, and / or the target code block includes a second target code block, the second target code block is a code block of the end type; the receiving device modifies the target code block to modify the target code block to The code block of the ordered set type in the second rate mode can ensure the transmission of the control code block and improve the accuracy of communication.
Description
technical field [0001] The embodiments of the present application relate to the communication field, and more specifically, relate to a method for receiving a code block stream, a method for sending a code block stream, and a communication device. Background technique [0002] Ethernet technology has been widely used in the network industry. Ethernet technology is greatly welcomed by network manufacturers for its concise, best-effort transmission mode and standardized interworking and interconnection mechanism. At present, the Ethernet technology has developed to a flexible Ethernet (flexible ethernet) 1.0 implementation protocol (hereinafter referred to as FlexE) based on the 100 Gigabit (Gigabit, G) Ethernet standard. The rate aggregation of FlexE supports multiple low-rate physical interfaces to carry high-speed Ethernet service data streams together, and sub-rate and channelization allow one Ethernet physical interface to carry multiple low-rate data streams concurrently...
