Device for realizing network fusion and its method

Abstract

The invention provides a device to realize network merge, which comprises: a data transceiver unit connected with Ethernet to receive and transmit data frame, a first data conversion unit to convert the Ethernet data frame into quasi-synchronous digital-architecture data frame then synchronous digital-architecture data frame to send to OTN and convert the data frame received in OTN into quasi-synchronous format then Ethernet data frame, a data transmission unit to transmit the Ethernet data frame received by transceiver to opposite the first data conversion unit or Ethernet data frame converted by the first conversion unit to opposite transceiver unit for send. It also provides a opposite method. This invention can save port resource of MSTP and investment.

Description

technical field [0001] The invention mainly relates to the fusion technology of Ethernet and optical transmission network, in particular to a device and method for realizing network fusion. Background technique [0002] Multi-Service Transport Platform (MSTP, Multi-Service Transport Platform) is the abbreviation of Synchronous Digital Hierarchy (SDH, Synchronous Digital Hierarchy) multi-service transport platform. developed on the basis of. Among them, SDH-based MSTP refers to an SDH-based transmission platform that simultaneously implements access, processing, and transmission functions such as time division multiplexing (TDM, Time Division Multiplexing) services, asynchronous transfer mode (ATM, asynchronous transfermode) services, and Ethernet services, and A multi-service processing node that provides unified network management functions. [0003] Due to the emergence of MSTP technology and the continuous development of Ethernet data service requirements, how to realiz...

Problems solved by technology

[0015] But in summary, the existing EoPDH device can only complete the point-to-point data forwarding service, that is, an EoPDH device needs to occupy an Ethernet port on the MSTP device and an Ethernet port on the remote MSTP device for data communications; such as Figure 4 As shown, this figure is a network structure topology diagram for realizing enterprise network deployment by using EoPDH devices in the prior art; Figure 4 As shown, in the construction of an enterprise network or an industry private network, the communication service type between the enterprise headquarters and each branch (shown in the figure as branch 1, branch 2 ... branch N) is often a point-to-multipoint communication service type , so that an EoPDH device needs to be installed corresponding to each branch at the enterprise headquarters, and each EoPDH device needs to occupy an Ethernet port on the MSTP equipment at the enterprise headquarters to communicate with the remote MSTP and its EoPDH device , so if there are many branch offices in the enterprise, it is required to configure a large number of Ethernet ports on the MSTP equipment at the headquarters (such as routers or access devices at the headquarters, etc.), and the port resources of the MSTP equipment at the headquarters are very precious, so it is bound to Cause unnecessary investment in equipment

[0016] Secondly, it can be seen from the above description that the EoPDH device is a plug-in device attached to the MSTP device, that is, the EoPDH device and the MSTP device are independent of each other, so since the E1 / E3 link between the EoPDH device and the MSTP device cannot provide The management overhead bytes of network maintenance, so the EoPDH device cannot perform unified network management and monitoring with MSTP equipment, and cannot achieve end-to-end management of the network system

[0017] At the same time, the existing EoPDH device only supports the conversion between the Enternet protocol and the PDH protocol, but does not support the EOS technology. Therefore, the existing EoPDH device cannot simultaneously support the conversion between the Enternet protocol and the PDH protocol, the Enternet protocol and the SDH protocol, that is, it does not support multiple protocols. conversion function
