Monitor linux traffic for shell and linux traffic for shell
If you want to view linux traffic in real time and do not want to go to a third-party tool, you can directly write and run it!
System: centos 6.5
Principle: Get the traffic from/proc/net/dev, and then get the traffic
PHP implements website traffic counters and php traffic counters
Simple website traffic counters are implemented as follows:
DescriptionIdeas:
1. the user sends an access request to the server2. The server reads the access count file, + 1, and returns it to the client3. The server saves new browsing times4. Access new users by repeating 123.

Xx CGI traffic control and xxcgi Traffic ControlTraffic control is divided into two steps. First, the user's ip address is restricted in the CGI framework, and second, the traffic of each CGI is restricted. 1. IP-based traffic control saves ip-based access information using shared memory (shm. In the configuration file
Traffic light Management system
Simulation to achieve the intersection of traffic lights management system logic, the specific requirements are as follows:
Ø randomly generated vehicles that follow each route.
For example:
Vehicles coming from the south to the north----straight vehicles.
Vehicles from the west to the south----turn right
Vehicles from east to south----left-turn vehicles

Title Link: BZOJ-1018Problem analysisThis problem shows that the brush problem is less, the game is easy to kneel. Sdoi Round1 Day2 T3 is similar to this problem. However, I have not done this problem.This problem is a classical model for maintaining the connectivity of line-segment trees.One node of our segment tree represents the connectivity of an interval, with 6 bool values representing the connectivity between points on the 4 corners of the interval.Then the connectivity of the whole inter
in which I point all flows ) –sum ( the Nether Stream where I point all flows out )Assuming that the mi is greater than 0and that the point must also flow out of the free stream to mi , then we connect a single mi edge from the source point to that point. Assuming that Mi is less than 0, this point must also flow in The free stream of MI. So we'll go from that point to the edge of a Mi to the meeting point. Suppose the maximum flow of the s->t is calculated to see if the full stream ( The n

Specific steps
1. We open the "Settings" button in the iphone to enter
2. Locate the "Cellular mobile Network" menu in the settings application
3. Then in the cellular mobile network we will see the mobile network management interface, where we will see the "Cellular mobile data Consumption" option.
4. In the cellular mobile data consumption we can see the use of traffic status.
5. Continue sli
1. The view method is very simple, but I feel as if the relevant software to use, click on the Phone "application" icon.2. Then go to the "set" icon.3. In the Open interface, we click on "Connection" under "Data Use", where you can see the use of traffic, and the specific application of how much traffic, so we can manage the application.
