Embodiment Construction

[0019] First, the technical terms involved in the technical solutions of the embodiments of the present application are given:

[0020] FlexE group: Multiple blocks are bound to form a FlexE group, that is, a logical channel is formed to transmit different business data.

[0021] FlexE Shim: In FlexE technology, Ethernet layer 2 (layer 2, L2) (ie, media access control layer (MAC)) and L1 (layer 1, L1) (ie, physical (PHY) layer ( layer)) between the middle layer is FlexE Shim. It is used to realize the multiplexing and demultiplexing from the FlexE client to the FlexE group.

[0022] The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations.

[0023] The terms "first" and "second" in the specification and drawings of the present application are used to dist...

Abstract

The invention provides a service traffic transmission method and apparatus, and relates to the field of communications. The service traffic transmission method and apparatus can reduce the data packetloss rate and improve the transmission reliability in a FlexE (Flexible Ethernet) technology. The method comprises the following steps: a network device determines a magnitude of a service traffic; and if the magnitude of the service traffic is greater than a threshold value, the network device transmits the service traffic via a shared channel and a pre-configured rigid channel of the service traffic, wherein the shared channel is configured to transmit at least one part of traffic in the service traffic and other service traffic, and the other service traffic is a service traffic except forthe service traffic.

Description

technical field [0001] The present application relates to the communication field, and in particular to a service flow transmission method and device. Background technique [0002] Currently, the industry has proposed a third-generation Ethernet technology, that is, Flexible Ethernet (Flexible Ethernet, FlexE) to provide higher-quality communication services. By adding the FlexE Shim layer to the existing Ethernet chip, FlexE can decouple the service rate of the FlexE client (Client) from the physical channel rate, that is, the service rate may not be equal to the physical channel rate. This means that a service of the client can be transmitted through a FlexE group (Group) formed by bundling multiple physical channels. Of course, each physical channel can also be divided into multiple logical blocks, so that different services can be carried on different blocks, and service isolation can be realized between different services, avoiding the gap between services. interferen...
