Embodiment Construction

[0086] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0087] As the types of transmission interfaces in the OTN continue to increase, the mapping relationship between different transmission interfaces becomes more and more complex, which in turn leads to an increasingly complex OTN transmission system. Schematically, in related technologies, the mapping paths between ODU1 (2.5Gbps), ODU2 (10Gbps), ODU3 (40Gbps), ODU4 (100Gbps) and ODUCn (n×100Gbps) are as follows figure 1 shown.

[0088] In order to solve the problem that the transmission system is complicated due to the expansion of transmission interface types, the embodiment of the present application provides an interface transmission method applied to a device with a variable interface. Optionally, the device with a variable i...

Abstract

The invention provides an interface transmission method, device and equipment. The method comprises the following steps: obtaining a byte block stream, wherein a byte block in the byte block stream isa predetermined byte length; Mapping the byte block flow into corresponding time slots, wherein each time slot corresponds to one byte block; Distributing the byte block streams mapped to the time slots; Processing the distributed byte block flow according to the interface type configured for the physical interface; And sending the processed byte block stream. In the embodiment of the invention,data transmission is carried out based on a byte block distribution mechanism, support for different interface types is realized, and a coupling relationship between service adaptation and a physicallayer is decoupled, so that evolution and extension of the transmission interface type do not influence a service adaptation process, and a transmission system is simplified.

Description

technical field [0001] The present application relates to the field of data transmission, in particular to an interface transmission method, device and equipment. Background technique [0002] With the continuous growth of service traffic and the continuous enrichment of service types, the transmission technology of the transport network has also evolved and developed accordingly. [0003] Optical transport network (OTN), as the core technology of transport network, has evolved from traditional OTN to multi-service optical transport network (Multi-Service Optical Transport Network, MS-OTN), and further to the flexible Optical Transport Network (Flexible Optical Transport Network, Flex-OTN) evolution. Through the flexible bearing of services, the flexible line port rate provides a flexible and efficient end-to-end bearing solution, which meets the fine-grained operation requirements of operators for bandwidth resources. [0004] In order to support different service rates, ...
