Problems solved by technology
[0005] Aiming at the defects existing in the prior art, the purpose of the present invention is to provide a network routing protocol testing device and method for network element management disks. The equipment can be cascaded in multiples, and can easily simulate dozens of nodes on the project. Large-scale network configuration saves resource share, saves manpower, and makes it easier to find hidden network routing problems caused by multiple nodes sending and receiving data packets in large-scale networks

Embodiment Construction
[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0023] Such as figure 1 As shown, the network routing protocol testing device for the network element management disk of the present invention includes a backplane, a plurality of optical transceiver units, a plurality of network element management disks, a signal control module and a signal on-off controller. The backplane includes a plurality of optical transceiver unit interfaces (such as figure 1 In b and c), multiple optical transceiver units are respectively connected to the backplane through the interfaces of the optical transceiver units. The backplane also includes a plurality of network element management disk interfaces (such as figure 1 In a and d), multiple network element management disks are respectively connected to the backplane through network element management disks and interfaces. A network element management disk plus ...

The invention discloses a device and method for testing networking routing protocol used for NMUs and relates to the testing field of the NMUs. The device comprises a backing plate, a plurality of light receiving and sending units and a plurality of NMUs, one NMU and one corresponding light receiving and sending unit form one simulated network element. The method comprises the steps that the NMUs transmits electrical signals to the corresponding light receiving and sending units in the same simulated network elements through the backing plate after processing DCC signals; the light receiving and sending units convert the electrical signals into light signals and transmit the light signals into the simulated network elements connected with the light receiving and sending units; the light receiving and sending units receive the light signals, convert the light signals into the electrical signals and then transmit the electrical signals to the NMUs through the backing plate, and the feasibility of OSPF routing protection operation of the NMUs is verified. The device can be in multiple cascade connections, large network configuration with dozens of nodes in engineering can be easily simulated, resource occupancy rate is reduced, labor is saved, network routing hidden troubles due to the fact that the nodes receive and send data packets in the large networking can be found more easily.
Description
technical field [0001] The invention relates to the testing field of a network element management unit (NMU, Network Element Management unit), in particular to a network routing protocol testing device and method for a network element management unit. Background technique [0002] DCC (Data Communications Channel) is a physical channel for transmitting network management information in an SDH (Synchronous Digital Hierarchy) system. In the network block of an optical network, the information between Ma / Mb (Managers A / B manager A / B) and A (agency agent) is transmitted through it, and the information between workstation WS (workstation) and Ma / Mb Sometimes it is also transmitted through it, and the section overhead DCC of SDH is used to form the transmission link of the SDH management network. DCC is common, and it is embedded in the section overhead of SDH in order to form a unified management network. [0003] The networking routing protocol of the traditional network eleme...
