Abstract
The invention discloses an FC network simulation card with high transmission efficiency. The FC network simulation card comprises a central processing unit, an interface testing adapter, a first reference clock chip, a second reference clock chip and an FPGA. The interface testing adapter, the first reference clock chip, the second reference clock chip and the FPGA are all connected with the central processing unit, and a plurality of testing ports are connected to the interface testing adapter. On the basis of the principle, information of the testing ports can be recognized and judged by the interface testing adapter, then, the processed information is sent to the central processing unit, and therefore transmission efficiency is improved.
Description
Technical field
The present invention relates to network port field, be specifically related to the FC network simulation card that efficiency of transmission is high.
Background technology
The FC network simulation card that efficiency of transmission is high is used for the definition according to the FC agreement, realizes data communication.Specifically comprise the data encapsulation from user's software is become to the FC frame, according to sending protocol requirement, send in the FC network; From the FC network, receive the FC frame of the port, parse user data, be submitted to user software.In dual-port communication, two of system requirements are dual-port independently, can independently carry out data communication, can distinguish a network equipment.Due to the FC artificial card, adopt the data of two ports of a PCIE interface transmission, need to carry out the data separation of two ports.During single port communication, bi-directional data bandwidth transmission rate 160MB/s, receive 180M/s; Each port bi-directional data bandwidth transmission rate 120MB/s during dual-port communication, receiving velocity 160MB/s.In the face of above bandwidth requirement, the efficiency of transmission that how to improve PCIE is the key that guarantees bandwidth.In prior art, also can't realize identification data from port, also just can't illustrate that data are to mail to which port, can only to two ports, transmit simultaneously, reduce transmission rate.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, and the FC network simulation card that efficiency of transmission is high is provided, and can to test port information, identify judgement by interface adapter, and process information is sent to central processing unit, improves efficiency of transmission.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: the FC network simulation card that efficiency of transmission is high, comprise central processing unit, interface test adapter, the first reference clock chip, the second reference clock chip and on-site programmable gate array FPGA, described interface test adapter, the first reference clock chip, the second reference clock chip all are connected with central processing unit with on-site programmable gate array FPGA; On described interface test adapter, connect a plurality of test ports.
On described on-site programmable gate array FPGA, connect optical transceiver module.
The model of described optical transceiver module is FTRJ-8519-1-2.5.
Connection data buffer storage FLASH, static random access memory SRAM and PCI-EXPRESS X4 interface on described on-site programmable gate array FPGA.
The model of described the first reference clock chip is MAX DS4106.
The model of described the second reference clock chip is MAX DS4212.
Compared with prior art, the invention has the beneficial effects as follows:
1, interface test adapter of the present invention can be that AD converter and codec chip form, by interface test adapter, central processing unit is processed and sent to the data that receive from test interface, realization, to the identification of test interface information and effectively transmission, improves efficiency of transmission.
2, the optical transceiver module in the present invention is the interface device that a kind of signal of telecommunication is converted to light signal, realizes any conversion to photosignal.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Embodiment
The present invention is further elaborated below in conjunction with accompanying drawing, and embodiments of the invention are not limited to this.
Embodiment:
As shown in Figure 1, the present invention includes central processing unit, interface test adapter, the first reference clock chip, the second reference clock chip and on-site programmable gate array FPGA, on on-site programmable gate array FPGA, connect optical transceiver module, the model of optical transceiver module is FTRJ-8519-1-2.5.Connection data buffer storage FLASH, static random access memory SRAM and PCI-EXPRESS X4 interface on on-site programmable gate array FPGA.The interface test adapter of the present embodiment, the first reference clock chip, the second reference clock chip all are connected with central processing unit with on-site programmable gate array FPGA; On described interface test adapter, connect a plurality of test ports.The model of the first reference clock chip is MAX DS4106, and the model of the second reference clock chip is MAX DS4212, and the model of FPGA is XC5VLX110T, and the model of central processing unit is ARMCORTEX M3.
The FC network simulation jig that efficiency of transmission is high has two data transmission interfaces, by interface test adapter, central processing unit is processed and sent to the data that receive from test interface, and interface test adapter can be that AD converter and codec chip form.Interface test adapter wherein can be identified the information of test port, carries out effective transmission of data, has improved efficiency of transmission.
Just can realize this invention as mentioned above.
