Recently see the POF code to see the headache, but fortunately is done, the rest is the idea of POF can be integrated into the code of the EPC, I also for the future 5G point of view is not? First of all, say what POF is.Introduction to POFThe full name of the POF (Protocol oblivious Forwarding) is the protocol is not
same time, it also has the advantages of softness, bending resistance, vibration resistance, anti-radiation, low price, and convenient construction, which can replace the traditional Z optical fiber and copper cable, and is very suitable for local networks with many connection points.
Using Plastic Optical Fiber to construct a large-scale local area network requires two products: passive wiring and connecting products and active plastic optical fiber network equipment.

, flexural, vibration resistance, radiation, cheap, easy construction advantages can replace the traditional quartz fiber and copper cable, is ideal for the connection point of more local area network.
The use of plastic optical fiber construction of large-scale local area network, the need for two products, namely, passive wiring connection products and active plastic optical fiber network equipment

Sof = FPGA internal SRAM configuration data, which can be downloaded through JTAG. After downloading, the hardware functions of FPGA are implemented. After power loss, the hardware becomes volatile.POF = configure the flash data of the device and download it to the configuration device in as mode. When the device powers down and is powered on again, FPGA will automatically read the configuration data from the configuration device, a
Recently, Siemens launched a new Industrial Ethernet (Industrial Ethernet) POF and PCF cabling system with SC RJ connector.
POF and PCF optical fiber cables can be easily assembled on site using PROFINET-compatible SC RJ connector. The two end-to-end toolbox can be used for on-site cable assembly:

The construction of POF environment one. General overviewThe architecture PC1 is the controller, and the PC2 is the switch. PC3 is a server/client (a PC with two virtual machines, you need to set the network connection mode to bridge.) According to the network segment of the laboratory to assign IP, the following chapters are detailed), in this build tutorial, controller for the host, PC2 and PC3 for the host of two virtual machines.Two Configuration

Altera's Quartus II development tool can generate multiple configuration or compilation files for different configuration methods. For different target devices, after compilation, the development tool automatically generates the ". Sof (SRAM object file)" and ". POF (programmer objectfile)" configuration files based on the specified FPGA device. The. Sof configuration file is downloaded
SOF, POF and elf sof = FPGA internal SRAM configuration data, download through the JTAG, after the implementation of FPGA hardware function, after the electricity is evaporated.
POF = Configure the device flash data, download the as mode to configure the device, after power off, the FPGA will automatically read the configuration data from the configuration device, then configure the SRAM inside the FPGA t
