Packet slicing method and apparatus, and computer-readable medium

A packet slicing apparatus, comprising a processor and a memory, wherein the memory is coupled to the processor for storing a computer readable program, which when executed by the processor causes the processor to:

• perform a start of packet (SOP) detection on a data packet to obtain a first detection result;
• perform an intermediate detection on the data packet to obtain a second detection result;
• perform a packet tail mark detection on the data packet to obtain a third detection result;
• and
• the processor is further configured to:
• when the first detection result indicates that the data packet satisfies a condition for inserting a first burst control word, insert the first burst control word and fill data control words, each corresponding to an interface bit width, in a unit of the interface bit width;
• when the second detection result indicates that the data packet satisfies a condition for inserting a second burst control word, insert the second burst control word and fill one or more data control words, each corresponding to an interface bit width, in a unit of the interface bit width;
• and when the third detection result indicates that the data packet has a packet tail mark, insert fixed number of idle control words;
• wherein the first detection result indicates that the data packet satisfies a condition for inserting a first burst control word, including:
• the data packet carries a packet header mark;
• or, a channel number of the data packet varies;
• or, an accumulated data packet length corresponding to the data packet is equal to a BurstMax,
• the second detection result indicates that the data packet satisfies a condition for inserting a second burst control word, including:
• an optional scheduling enhancement corresponding to the data packet is active.

A non-transitory computer-readable medium stored therein executable instructions that, when executed by a processor, cause the processor to execute a method for packet slicing, the method comprising:

• performing a start of packet (SOP) detection on a data packet to obtain a first detection result;
• when the SOP detection result indicates that the data packet satisfies a condition for inserting a first burst control word, inserting the first burst control word and filling data control words, each corresponding to an interface bit width, in a unit of the interface bit width;
• performing an intermediate detection on the data packet to obtain a second detection result;
• when the second detection result indicates that the data packet satisfies a condition for inserting a second burst control word, inserting the second burst control word, and filling one or more data control words, each corresponding to an interface bit width, in a unit of the interface bit width;
• performing a packet tail mark detection on the data packet to obtain a third detection result;
• and
• inserting, when the third detection result indicates that the data packet has a packet tail mark, a fixed number of idle control words,
• wherein the first detection result indicates that the data packet satisfies a condition for inserting a first burst control word, including:
• the data packet carries a packet header mark;
• or, a channel number of the data packet varies;
• or, an accumulated data packet length corresponding to the data packet is equal to a BurstMax,
• the second detection result indicates that the data packet satisfies a condition for inserting a second burst control word, including:
• an optional scheduling enhancement corresponding to the data packet is active.
