Bridge Bridging Mode (structural mode)Abstraction and implementationAbstractions should not be dependent on implementation details, and implementation details should be dependent on abstraction.Abstract b stability, implementation details B changeThe problem is that if abstract B is inherently unstable and likely to change because of its inherent causes, what happens?For exampleIf we need to develop a tank game that supports both PC and mobile, the ga

Ask for a graph, each point has a degree of k and must have at least one bridge.Construction questions:Only k for odd time have solution, construct such a diagram, left a regiment has k+1 point, right a regiment also has k+1 point, middle through M1, M2 attached a bridge.If the left and right two regiment is a complete picture, then each point has a degree of k, and now consider how to connect it by m1,m2 without changing the degree.Obviously the graph is symmetrical, only consider the left and

N people wish to cross a bridge at night. A group of at most two people may cross at any time, and each group must have a flashlight. only one flashlight is available among the n people,
So some sort of shuttle arrangement must be arranged in order to return the flashlight so that more people may cross.
Each person has a different cr

Basic concepts:
1. cut point: if a vertex is deleted and the original connected graph is split into multiple subgraphs, the vertex is calledCut Point.
2. cut Point Set: In an undirected connected graph, if there is a vertex set, after deleting this vertex set and the edge associated with all vertices in this set, when the source image is changed to multiple connected blocks, This vertex set is calledCut P
Summary

Bridge
Structure
Motivation
Separate the abstract part from its implementation part so that they can all change independently.
Applicability
You do not want to have a fixed binding relationship between the abstraction and its implementation. For example, this may be because the implementation part of the program should be selected or switched during the runtime.
Class abstr
Abstraction should not depend on implementation details. Implementation Details should depend on abstraction.
Motivation ):
Some businesses have multiple changing perspectives.
Intent (Intent ):
The abstract part is implemented in part separation so that they all change independently.

Vmwarevm quick connection using Bridge Mode
Setting the vmwarevm to a bridge to access the Internet is equivalent to connecting your host machine and virtual machine to a switch on the same LAN. Once you understand this principle, the remaining problems are:
In the virtual machine settings, select to use:

1. Why the bridge design mode?
Let's talk about the differences between integrated components and independent components in computer hardware. Let's talk about integrated components first.
The memory box contains a theme called a motherboard, which is used to plug in various components, such as sound cards, video cards, and hard disks, and then coordinates these components for work.
In fact, the earliest computers were all integrated components, that
the method of setting up wireless bridge in tl-wr840n router
To confirm the need for bridging the signal parameters, that is, the main router's wireless signal name, wireless password, the following only do this article for example:
Note: All of the operation of Wireless bridging (WDS) is done at the secondary router without setting up the primary router.

The computer connects to the LAN port or wireles
VMware in the network settings bridged is also on the Linux under the VMware Bridge mode, static IP network configuration, but at that time more with the graphical interface to achieve, not strong commonality. Production environment, very few Linux installation graphical interface. Simply the original blog also do not modify, a new one got. Here I use the CentOS6.5 minimal system to demonstrate. Currently, because CentOS belongs to the Red Hat series,

To confirm the need for bridging the signal parameters, that is, the main router's wireless signal name, wireless password, this article uses the following parameters for example:
Note the problem: the main operation of wireless bridging (WDS) is performed at the secondary router.
Step two, log on to the tl-wr885n (Vice) router Setup interf

Primary and secondary routers through the wireless WDS Bridge, wireless terminals can connect the main and secondary routers online, mobile process can be automatically switched to achieve roaming. The topology is as follows.
Attention
1, the primary and secondary routers do not connect network cable;
2, WDS
After I use Vitualbox to create a virtual machine, I usually need to set up the bridge network to simulate a more real server environment. However, it is sometimes found that Vitualbox will not be able to set the bridge from the host host because the NIC cannot be found, as shown in the following illustration:
After finding the data found that this is because the bri
