Abstract

Disclosed in the present invention is a FLEXE service-based cell exchange method, relating to the field of communications, the method comprising the following steps: sequentially segmenting, at a sending terminal, a FLEX data code stream into several slice packets, and inserting a packet overhead with a time stamp into the slice packet (S2); a receiving terminal caching a received slice packet (S4), parsing the packet overhead before or after caching the slice packet, to obtain the time stamp of the slice packet, and obtaining a path latency of the slice packet according to the time stamp of the slice packet and the time when the receiving terminal has received the slice packet, determining whether the path latency of the slice packet exceeds a preset maximum line latency, if not, reading the slice packet, removing the packet overhead of the slice packet, and then recombining the payloads of the slice packets, and if so, sending an alert signal (S5). The cell exchange method implementing ultra low latency on the basis of a FLEX service provided by the present invention caches and forwards slice packets after slicing processing, thereby achieving high transmission efficiency and reliability.
