FLEXIBLE ETHERNET-BASED SERVICE FLOW TRANSMISSION METHOD AND APPARATUS, AND COMMUNICATION SYSTEM

摘要

The present application provides a method and apparatus for transmitting a service flow based on a flexible Ethernet. Here, the bandwidth resource corresponding to the bundling group of the flexible Ethernet is divided into M timeslots, and service data of at least one service flow is encapsulated in N timeslots within the M timeslots. If the first PHY fails, determining a target timeslot within the N timeslots mapped to the first PHY based on a preconfigured first timeslot configuration table; Searching M timeslots for idle timeslots based on the first timeslot configuration table; If the number of idle timeslots in M timeslots is greater than or equal to the number of target timeslots, adjust the first timeslot configuration table so that all N timeslots can be mapped to other PHYs other than the first PHY in the bundling group. Thus, obtaining a second timeslot configuration table; And transmitting at least one service flow based on the second timeslot configuration table by using the bundling group. The technical solution provided in this application can effectively avoid service flow interruption.
