Transplantation of DM8168 dvr rdk nand System
Nand boot preparation:
Method 1: Set the Startup Mode of DM8168 to SD card boot. After U-boot is started, run U-boot to write the applicable bootloader of nandflash to DM8168.
Method 2: This is also the method I have selected. It is simple and crude. Use the CCS project to write uboot_NAND_DM816X_TI_EVM to nandflash on the premise that there is a simulator.
I mentioned before the method of writing: http://
1. Background
No DVR scenarios are used:
It is clear from the diagram that the east-west and north-south traffic will be centralized to the network nodes, which will make the network nodes a bottleneck.
If you enable DVR, the following figure:
For east-west traffic, traffic is passed directly between compute nodes.
For the north-South flow, if there is floating IP, traffic directly to the compute
What is ddns network connection?According to statistics, for the vast majority of Enterprise leased line users, the total time for data flow on the leased line is no more than 8 hours. This means that a leased line user has to pay 2/3 of the time every day instead of using network resources. The price of leased lines remains high, so that ordinary enterprise users are discouraged. Therefore, the ideal way for enterprises to access the Internet is to a

The DDNS (dynamic Domain name Server) is an abbreviation for the service.DDNS is the user's Dynamic IP Address mapped to a fixed Domain Name Resolution service, each time the user connects to the network, the client program passes the message Host The dynamic IP address that is located on the service host Server program, the server program is responsible for providing the DNS service and implementing Dynamic Domain Name resolution .
