First, the preface
Cisco recently released a report saying that global networking equipment is expected to increase from 5 billion units to 15 billion by 2015, and 2015 Global monthly Internet traffic will increase from 1 bytes in 2004 to 80 bytes (1 MB = 1 billion GB). In the face of such a huge internet equipment and data flow, it is bound to have a corresponding number of basic wiring system to support, especially in the relatively centralized

In the 5G era, what data centers do carriers need ?, 5G data center
Mobile communication networks evolve every ten years. With the arrival of 2018, the masses are one step closer to the 5G era. However, behind this is a "war" that is invisible to the 5G era, but it has quietly started between operators.
In the 5G era, operators are on the new starting line

To do this, you must first sharpen the tool and analyze what STL needs to do? To analyze STL, you may need to be familiar with the basic C ++ syntax and understand generic programming. Finally, STL source code analysis.
This series of articles has no intention of analyzing the specific internal implementation of STL, because there are a lot of Daniel on the Inte

Preface
The IDC room is also a long-running battle. I encountered a self-testing problem in the middle and was isolated by myself for a while. However, this just shows that my time management is poor, it seems that the direction of my future efforts has been found. When starting to knock on the data center, as said by Shi Ge, try to avoid the ready-made code used by SHI Jie, and think about the function imp
