Description
Technical field
The present invention relates to technical field of optical fiber communication, relate in particular to the method for testing of performance of network equipments, more particularly, relate to a kind of method and device of test PON (Passive Opical Network EPON) local side hardware performance.
Background technology
Along with the extensive expansion of Ge great operator " broadband speed-raising ", " light entering and copper back " engineering, optical fiber access has impayable advantage aspect bandwidth capacity and coverage distance, the particularly sustained and rapid development of the Internet, the business such as online game, video conferencing, video request program, make user continue to increase the demand of network insertion bandwidth.
PON technology is as one of main access way of operator.FTTH (Fiber to the home for Fiber To TheHome) can not only provide larger communication bandwidth, and can allow multiple operators arrive user by an optical fiber equal access, this both can allow user have the real autonomous power of selecting Virtual network operator, the caused wasting of resources of also can avoiding overlapping construction.Along with FTTH is in the large-scale application of operator, the port number originally using is few, and low capacity PON local side apparatus more and more can not meet the demand of operator, the substitute is large capacity, highdensity equipment contributes to reduce operator's cost, improves and disposes flexibility.Therefore be also vital to the hardware performance test of PON local side apparatus.
As shown in Figure 1, for traditional PON local side apparatus testing apparatus schematic diagram, 1 PON mouth need to take 2 ports of network tester and edit 2 data message flows (each 1 of up-downgoing data flow), (N is natural number) the individual PON port test of supposing there is N, needing network tester port number is 2N and configuration data stream 2N bar.The shortcoming of traditional PON local side apparatus hardware performance method of testing is: in the situation of this method for PON mouth quantity few (PON port number <5), test more for convenience, and for thering is highdensity PON mouth quantity (PON port number >5), some is loaded down with trivial details, need to take more network tester port resource, the testing cost of increasing input.Conventional PON business board has 16 PON ports in the market.
As shown in Figure 2, it is existing PON local side apparatus hardware performance testing apparatus schematic diagram, traditional method of testing, application reference publication No. is the Chinese invention patent application file of CN102497229A, in literary composition, mention the method for utilizing 1 port of network tester to complete all port tests of PON local side apparatus, adopt the shortcoming of this method of testing to be: 1, send data flow to multiple PON ports by 1 port of network tester simultaneously, and the speed of 1 port of described network tester must be greater than the summation of all ONU upstream rates, the upstream rate surface speed forwarding of the most basic 900M of all ONU of guarantee like this.If according to 16 PON port tests conventional on market, network tester at least needs a 16G port could meet the most basic up surface speed forwarding so, therefore require very high for network tester like this, need to purchase corresponding two-forty port instrument and test, testing cost increases greatly; 2, network tester port sends downstream data flow, while being forwarded to another ONU through ONU, become upstream, article one, data rheology changes two kinds of different rate tests into, due to the not reciprocity characteristic of PON upstream and downstream speed, this can cause the downstream rate of the most basic 950M not reach surface speed forwarding.Therefore the method can only meet testing uplink speed, can not meet test downstream rate.
