Background technology
In recent years, newly-built in a large number along with 3G, 4G network, the rapid emergence of mobile Internet business, traditional SDH (Synchronous Digital Hierarchy, SDH (Synchronous Digital Hierarchy)) network cannot meet the data service of current growth at full speed, and the PTN equipment therefore with more Ethernet characteristics is used in a large number.Because traditional SDH transmission equipment test is mainly the test for indexs such as the error rates, only need the independent off-line test of individual equipment, and along with upgrading and the evolution of network function, the test of PTN equipment is mainly the test for frame link layer, error code testing is no longer applicable.Because network characteristic is different, PTN test can not be at same VLAN (Virtual Local Area Network, VLAN) in, carry out, and the test based on Ethernet index needs dual-port series connection test data stream, so traditional SDH single port off-line test method is no longer applicable.
Manufacturer is to use the laboratory instruments such as SmartBits to FE to the main method of testing of PTN equipment now, the ethernet ports such as GE carry out dual-port series connection test Ethernet index of correlation, it is connected on PTN equipment to be measured, with virtual 2 the different VLAN of the dual-port test of connecting, but can have problems, this class instrument originally designs as laboratory environment on the one hand, its volume is larger, be not easy to carry, again purchase on the other hand after new instrument, original SDH test instrumentation can only directly be eliminated, wasted existing resource, use cost and the cost of investment of PTN equipment have indirectly been improved, for the popularization of PTN equipment brings certain obstruction.

Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, each execution mode of the present utility model is explained in detail.Yet, persons of ordinary skill in the art may appreciate that in each execution mode of the utility model, in order to make reader understand the application better, many ins and outs have been proposed.But, even without these ins and outs and the many variations based on following execution mode and modification, also can realize each claim of the application technical scheme required for protection.
The first execution mode of the present utility model relates to a kind of test macro of PTN equipment, comprises: the test instrumentation 301 of Packet Transport Network PTN equipment to be measured, first line of a couplet PTN equipment 102, loopback device 201 and single ethernet port.
The test macro of the PTN equipment in present embodiment adopts loopback test method.Loopback test is the conventional method of PORT COM/line upkeep and troubleshooting, because simple and convenient, do not need specific instrument and software, just can locate rapidly the fault of port/circuit and be CT (Communication Technology, the communication technology) extensive use of/IT (Information Technology, information technology) technician institute.
Loopback test is exactly by short circuit is carried out in the sending and receiving end of equipment under test or circuit, allow tested equipment receive the signal oneself sending and judge whether circuit or port exist breakpoint, also can hang tester on by the circuit of loopback and test by the transmission quality of one section of circuit of loopback.
When can tentatively judging by phenomenon of the failure while being circuit question, conventionally from the equipment of one end, from nearest node to this equipment loopback, progressively expand to again the node of one-level far away, the node of farther one-level, with repeatedly different nodes to same equipment loopback, to determine the end is to have problems between which two node, such method is called sectional loop-back test.
Loopback test is divided into soft loopback and hard loopback, is also called software loopback and Hardware loopback, is generally called for short soft ring and hard ring.Software loopback is by the software support of one end equipment, forwards transmitting terminal to and sends, to reach the object to remote equipment loopback with the signal that the network management software is directly received local device receiving port (Rx).Some equipment is not supported soft ring.Hardware loopback is fairly simple, directly with hardware, Tx and the Rx of certain node (comprising device port) on circuit are carried out to short circuit, to reach to by the object of shorted end loopback, general sectional loop-back test all adopts also and can only adopt Hardware loopback, software loopback is general only for from one end equipment to other end equipment---comprise that all circuits between this terminal device carry out loopback test, are also called whole section of loopback.
Specifically, it is example that present embodiment be take the PTN equipment 101 to be measured that model is 3900, adopts hard loopback, is described further:
PTN equipment 101 to be measured is connected with its first line of a couplet PTN equipment 102, and loopback device 201 loopbacks are connected on this first line of a couplet PTN equipment 102, specifically, is the communication port that is connected to first line of a couplet PTN equipment 102.The test instrumentation 301 of single ethernet port is connected on PTN equipment 101 to be measured, for testing the Ethernet index of PTN equipment 101 to be measured.Specifically, the loopback device 201 in present embodiment can be Ethernet Loopback device 201, and the model of Ethernet Loopback device 201 can be ET120.
It is worth mentioning that, the model of the test instrumentation 301 of the single ethernet port in present embodiment is ET520.
In addition, also it should be noted that, in present embodiment, between PTN equipment 101 to be measured and its first line of a couplet PTN equipment 102, with optical fiber, be connected.
The utility model execution mode in terms of existing technologies, the main distinction is: utilize loopback device 201 loopbacks to connect after the first line of a couplet PTN equipment 102 of PTN equipment 101 to be measured, under the VLAN of two distinct devices, form the data streaming service of a loopback, even if utilize like this test instrumentation of existing single ethernet port also can carry out the test of Ethernet index to PTN equipment 101 to be measured.The test instrumentation small volume of existing single ethernet port, is easy to hand-heldly, is convenient to tester's carrying when maintenance work.As a rule, use the manufacturer of PTN equipment all to use SDH equipment before, also just have the test instrumentation of SDH equipment, when test PTN equipment, use existing test instrumentation, more make manufacturer after using PTN equipment, do not need to give up original test instrumentation, and purchase novel test instrument, effectively reduce the testing cost of PTN equipment, saved investment, can obtain the test data of the corresponding port of many complete equipments again simultaneously, improve production efficiency, become a test macro being more suitable in Practical Project.
The second execution mode of the present utility model relates to a kind of test macro of PTN equipment equally, the second execution mode and the first execution mode are roughly the same, the main distinction is: the quantity of the first line of a couplet PTN equipment 102 in the first execution mode is one, and the quantity of first line of a couplet PTN equipment 102 in present embodiment is a plurality of, specifically, loopback device 201 also has a plurality of, first line of a couplet PTN equipment 102 and loopback device 201 are corresponding one by one, in the process that each PTN equipment loopback is connected, all adopt hard loopback to connect loopback device 201 each first line of a couplet PTN equipment 102.While making PTN testing of equipment, can test a plurality ofly simultaneously, further accelerate the test speed in practical application.
It is worth mentioning that, first line of a couplet PTN equipment and PTN equipment to be measured equipment in actual applications can be identical, so when reality is tested, test instrumentation is connected on the PTN equipment that needs test and can tests this PTN equipment.
Persons of ordinary skill in the art may appreciate that the respective embodiments described above are to realize specific embodiment of the utility model, and in actual applications, can to it, do various changes in the form and details, and do not depart from spirit and scope of the present utility model.
