interface of the sharp weapon, And his certainty is that the speed of operation is slow, but also for the installation of machine configuration requirements are high.4. ScriptsScript is the soul of the configuration software, most of the configuration software to see the script can be distinguished from the bottom of the high school products, the foot is compiled and interpreted, the compiler needs to be in the configuration software is not run, the statement is compiled on one side, and then n

Layer-3 switch structure: ASIC chip and CPUThe ASIC chip is used for layer-2 and layer-3 forwarding. It contains a MAC address table for layer-2 forwarding and a layer-3 forwarding table for IP forwarding.The CPU is used for forwarding control. It mainly maintains some software table items (including route tables and ARP tables) and configures the hardware layer-3 forwarding table of ASIC based on the forwarding information of Software Table items.What determines high-speed forwarding is the two

-speed forwarding is the two-tier hardware table item of ASCIC, while the hardware table of ASIC comes from the Software Table item maintained by the CPU. Assume that A and B are in different VLANs of different network segments, and route forwarding is performed through the SVI interface of the layer-3 switch in the middle. ApingB data stream analysis is as follows: host A checks the IP address of target B, which is not in the same network segment as

The first time I tried to analyze the MySQL source code, I had to trace it back to two years ago, but it was hard to download the source code to the local machine until today. :) Make a backup, so the memory is not as bad as the pen. Calculate sloccount.CodeIs millions of rows, C ++, and ascic-based. In terms of scale, it is no inferior to WPS. After a year and a half, I picked up C ++.
