Description
Technical field
The present invention relates to communication technical field, relate in particular to method and system, communication node and the server of the unified transmission of a kind of different kinds of business.
Background technology
Digital communications network is from voice-based SDH (Synchronous Digital Hierarchy) (SDH, Synchronous DigitalHierarch) widely used till now Ethernet (Ethernet), the quick growth of data communication, the increase of data throughout has brought huge pressure to network, telecom operators are by constantly expanding band width in physical and correlation technique, increased the ability of network transaction data, but the increase of band width in physical is to lag behind the requirement of user for transfer of data forever.
Along with television broadcasting (IPTV based on the IP agreement, Internet Protocol Television) etc. new the rising and EPON (PON of using, Passive Optical Network) use of technology, requirement realizes the unified transmission of multiple business in communication network, such as real time business such as voice, the non-real-time service that video, online game equiband guarantee, and other non-real-time service such as network browsing.Because the impossible unconfined increase of the bandwidth of communication network, transfer of data not only needs to carry multiple business, and needs reasonable distribution channel width to adapt to the bandwidth demand of different kinds of business, guarantees for different kinds of business provides different service quality.
In the prior art, the data frame structure of SDH as shown in Figure 1.The Frame of SDH is also referred to as STM-N (Synchronous Transmission Module level N, N level synchronous transfer module), and the STM-N frame is to be the rectangular block shape frame structure of unit with the byte.As can be seen from Figure 1: the signal of STM-N is the frame structure of 9 row * 270 * N row, and N herein is consistent with the N of STM-N, span: 1,4,16, and 64.......Identifying this signal is formed by N STM-1 signal byte intertexture division multiplexing.The frame structure of STM-1 signal is the block frame structure of 9 row x270 row, and the row of N STM-1 signal are obtained the STM-N signal by byte intertexture division multiplexing.
The frame frequency of STM-N signal was 8000 frame/seconds, and frame length is 125 μ s.The frame structure of STM-N is made up of 3 parts: section overhead (comprises RSOH-RSOH, MSOH-MSOH), Administrative Unit Pointer--AU-PTR, information payload---payload.SDH is packaged into customer data by certain rule can data packets for transmission, puts into the corresponding transmission channel of information payload and transmits.
In research and practice to prior art, the inventor finds to exist at least in the prior art following defective: SDH can't distinguish the customer data type, and the data of different types business has identical QOS.After the transmission channel configuration was finished, bandwidth fixed was constant, can't dynamically change according to the bandwidth demand of practical business, and then can not realize the statistic multiplexing of line bandwidth.
