Abstract

The embodiment of the invention discloses a method, device and network system for sending and receiving services. Wherein, the method for sending services includes: a network device acquires a first data flow and a second data flow; inserting the first data flow into the second data flow to generate a third data flow; the third data flow Contains a first information block and a second information block; the first information block is used to carry the first data flow; the second information block is used to carry the first data flow distribution indication map, and the first data flow The distribution indication map is used to indicate the position of the first information block, and the second information block is identified by a preset map block type. The utilization rate of network bandwidth resources is improved, and the statistical multiplexing of services is realized in the flexible Ethernet.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and network system for sending and receiving services. Background technique [0002] Flexible Ethernet (FlexE) combines some technical characteristics of Ethernet and transport network (for example, Optical Transport Network (Optical Transport Network, OTN), Synchronous Digital Hierarchy (Synchronous Digital Hierarchy, SDH), etc.), is the evolution of Ethernet technology A major milestone. With the emergence of flexible Ethernet technology, the Ethernet interface presents the characteristics of virtualization. Cascade multiple Ethernet physical interfaces to support several virtual logical ports. For example, four 100 Gigabit Ethernet (100Gigabit Ethernet, 100GE) physical interfaces are cascaded to form a 400 Gigabit (400 Gigabit, 400G) flexible Ethernet physical interface group, which can support several logical ports. The bandwidth of each logical port can ...
