METHOD AND SYSTEM FOR RECEIVING AND TRANSMITTING DIFFERENT DATA FRAMES ON DIGITAL TRANSMISSION NETWORK

摘要

A system for different data frames access and transport over a digital transport network for accessing and transporting different data frames, comprising: at least one User-Network Interface, which is used to couple with the user's network; and/or at least one Network-Network Interface, which is used to couple with said digital transport network to transport data; and a data converting device, which is coupled with said UNIs and said NNIs to convert data formats between said UNIs, or data formats between said NNIs, or data formats between said NNIs and said UNIs; wherein said data converting device comprises a virtual bridge device and an interface device, said virtual bridge device exchanges data between said UNIs and NNIs via said interface device, said virtual bridge device is used to detect control messages and transfers the control messages to a control system of the device via a control interface unit , and to perform exchanging on data frames in non-control messages, so as to solve the problem of limitation of address space of data frames for users.
