Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] see figure 1 As shown, the embodiment of the present invention provides an automated testing method for a network element management unit, including the following steps:

[0036]S1: According to the function of the EMU (ElementManagementUnit, network element management unit) that needs to be tested, select the corresponding EMU function configuration block in a plurality of EMU function configuration blocks; The key fields of the PDU (ProtocolDataUnit, protocol data unit) are modified regularly for many times, and after each modification is completed, an EMU message is generated and transferred to S2.

[0037] Multiple EMU function configuration blocks in S1 include: collaborative management function configuration block, used to cooperate with the network management server to perform configuration management, fault management,...

Abstract

The invention discloses an automatic test method of a network element management unit and a system, and relates to the field of test technology of network element management units. The method comprises steps of modifying key field of a PDU in an EMU function configuration block for many times and generating corresponding EMU message; comparing all the EMU message so as to obtain deviation values of the modified and changed key field in the PDU in the EMU message, and positioning the key field according to the deviation values; according to types of the EMU function configuration block, determining the unique value range and traversal algorithm, and determining one unique value via the traversal of the traversal algorithm in the value range of the unique value; and successively testing each of the unique values based on the traversal of the traversal algorithm until all unique values are traversed, and then finishing the test. According to the invention, automatic EMU test can be achieved; coverage rate of the test is high; test time is short; test efficiency is high; and manpower cost is low.

Description

technical field [0001] The invention relates to the technical field of testing network element management units, in particular to an automatic testing method and system for network element management units. Background technique [0002] With the wide application of optical transmission equipment, the network capacity is continuously upgraded, which makes the network topology become quite complicated due to the improvement of the optical branching capability of the optical transmission equipment itself. At present, the networking of the network management system is generally carried out by using EMU (Element Management Unit, network element management unit) by means of DCC (Data Communications Channel, data communication channel) channels or Ethernet, so EMU has become the best network in the network management system at the network element level. The basic and most important unit platform. [0003] PDU (ProtocolDataUnit, protocol data unit) refers to the data unit transmitt...
