Brief introductionEditThe general form of the Box-cox transformation is: The new variable obtained by the Box-cox transformation in the formula is the original continuous dependent variable, which is the transformation parameter. The above transformation requires the original variable value is positive, if the value is negative, you can first add a constant to all the original data to make it positive, and

In fact, we can leave aside all network protocol-related knowledge. This is just an extremely common one-way linked list operation, and the logic is not complicated. But let's look at how top hackers think about coding and compare the code they have written, how many times of data processing is done with a simple for loop without further thinking about the rough and unreasonable aspects? Do you have an in

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.

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
