Method, devices and system for optical network data processing

Abstract

The embodiment of the invention relates to a method, devices and a system for optical network data processing. The method comprises the following steps: at least two types of data frames are received; the data frames are recognized; and the data frames of the corresponding types are processed according to the recognition result. One device comprises a first receiving unit, an identifying unit and a first transmitting unit; and the other device comprises a second receiving unit, a recognition unit and a second transmitting unit. The system comprises an optical line terminal device and an optical network unit device. By processing the data frames of the corresponding types according to the recognition result of the received data frames, the optical network unit supporting the original protocol and the extended or updated optical network unit supporting the new protocol can be distinguished and recognized, different processing methods are adopted according to different protocol types of the optical network units, and fianally, the coexistence of the different types of the optical network units is realized.

Description

technical field [0001] Embodiments of the present invention relate to the field of network communication, and in particular, to a method, device and system for processing optical network data. Background technique [0002] With the increasing variety of telecommunications services, users' demand for bandwidth is also increasing. The original twisted pair and coaxial cable access technologies can make full use of existing copper wire resources, but cannot provide new services such as video on demand, Two-way video conferencing provides sufficient bandwidth, and the transmission distance is limited and the network coverage is small. However, the huge capacity and long-distance transmission of optical fiber determine that optical fiber access is the ultimate solution for broadband access. Therefore, operators at home and abroad have already implemented optical fiber to the home (fiber to the home, FTTH) as an inevitable choice for the access network. [0003] Such as figure 1...
