Problems solved by technology

[0004] The technical problem to be solved by the present invention is that there is currently a plan to realize the bearing of 1G and 1.25G small-grained services in FlexE in a flat manner, but the services supported by this plan are GE-level services and cannot support smaller-grained services. And this solution cannot ensure that small-grained services pass through the existing SPN network

Embodiment 1

[0074] Embodiment 1 of the present invention provides a method for implementing FlexE to carry small-grained services. In the embodiment of the present invention, the inserted OAM and / or idle codes in the service data are hidden through a round of mapping operations, so that other The identification method of network elements will be treated as general business data operations, thus avoiding the occurrence of data errors in the above-mentioned real-world scenarios. This is because in the prior art, a kind of flat processing is mostly used, which may cause the deletion of the idle code in the service data when other network units in the network perform speed matching, thereby causing data errors question. And the embodiment of the present invention proposes just after studying above-mentioned problems, as figure 1 As shown, the methods include:

[0075] In step 201, services to be carried are mapped to time slots of the divided FlexE sub-instances.

[0076] Wherein, the band...

Embodiment 2

[0125] The embodiments of the present invention will focus on illustrating the key points in the implementation process of the present invention and related implementation mechanisms in conjunction with the relevant data structure drawings. The following two specific examples are used to further illustrate:

[0126] If the minimum rate of the currently supported service is 100Mbit / s, please refer to Figure 8 As shown, Sub FlexEinstance (another form of expression of the FlexE sub-instance in Embodiment 1 of the present invention) is divided into 48 time slots, wherein a piece of "Slot0-47" represents a time slot, and its multiframe is defined as 64 Sub FlexE overhead frame. Figure 8 The distribution of 48 time slots in a SubFlexE overhead frame is shown in . It is not difficult to see from the figure that the bearer area 20460 between two overhead blocks may not be able to accommodate an integer number of time slots, but the payload area of ​​the FlexE sub-instance corresp...

Embodiment 3

[0131] like Figure 12 As shown in FIG. 1 , it is a schematic diagram of an architecture of an implementation device for carrying small-grain services through FlexE according to an embodiment of the present invention. The device for realizing the FlexE carrying small-grained services in this embodiment includes one or more processors 21 and memory 22. in, Figure 12 A processor 21 is taken as an example.

[0132] Processor 21 and memory 22 can be connected by bus or other means, Figure 12 Take connection via bus as an example.

[0133] The memory 22, as a non-volatile computer-readable storage medium, can be used to store non-volatile software programs and non-volatile computer-executable programs, such as the method for implementing small-grained services carried by FlexE in Embodiment 1. The processor 21 runs the non-volatile software programs and instructions stored in the memory 22, so as to implement the implementation method of the FlexE carrying small-grained servi...

Abstract

The invention relates to the technical field of transmission networks, and provides a method and a device for realizing a FlexE bearing small-particle service. The method comprises the following steps: mapping a service needing to be borne into a time slot of a divided FlexE sub-instance; after coding and rate adaptation are carried out on the FlexE sub-instance bearing the service needing to be borne, mapping the FlexE client serving as a specified rate to an existing FlexE network for transmission. According to the invention, the single time slot bandwidth of the FlexE sub-instance is set according to the minimum granular service, and subsequent cell coding packaging and rate adaptation are carried out on the basis of the time slot length setting, so the problem that the small granular service cannot be ensured to pass through the existing SPN network in the prior art can be overcome.

Description

【Technical field】 [0001] The present invention relates to the field of transmission network technology, in particular to a method and device for implementing FlexE carrying small granular services. 【Background technique】 [0002] With the advent of the 5G era, Ethernet technology has further developed. Network slicing is one of the key technologies of the 5G MTN\SPN (English full name of MTN: Metro Transport Network, Chinese explanation: Metro Transport Network; SPN full English name: Slicing PacketNetwork, Chinese explanation: Slicing Packet Network) network bearer solution. Network slicing and ultra-low-latency forwarding for different services provide an application foundation. As the core technology of Ethernet slicing, FlexE is widely recognized by operators. FlexE adds Shim layer time slot crossing to the original Ethernet frame structure, which greatly reduces the node delay of the bearer network. At the same time, the FlexE bandwidth is flexible and adjustable, and...
