Docker NetworkThe three networks of bridge, host, none are automatically created on the host when Docker is installed, and can be viewed with the Docker Network LS commandNone NetworkNone Network is any network, hanging in the network of containers in addition to Lo, there is no other network card, the creation of containers can be--network=none to specify the use of the None network. A none network is available for applications that have high security requirements and do not require networking.

Looking at the figure above, you may ask, how does the device know that the data packet is sent to the local device? In fact, this is not the responsibility of this device. How do you know that what I DMA to the Ring buffer is an Ethernet frame instead of a pure HTTP packet? In short, there is no such thing as the present, which is incredible. What's best about PF_RING is not

The code you see above is very poor, because it is very inefficient, millions of data, it takes more than 10 hours to run, how can I forget the basics of table connection query?

development efficiency.Linux 4.0 SwitchdevAll bad news ends up in the Linux 4.0 kernel.Linux 4.0 introduces a Switchdev framework that represents the abstraction of a class of multi-port devices with "switching" capability chips. Each of these network ports is a port that is registered as a net_device in the Switchdev framework. In addition, the kernel comes with a rocker driver, demonstrating an actual device-driven implementation. The entire switchdev is as follows:650) this.width=650; "src="
Today, we finally finished finishing the mininet part.First of all, this section is divided into two elements, one is a custom topology, and the other is a custom flow table.1. Open Ubuntu.2. Create a new terminal and enter Java-jar Target/floodlight.jar to start the floodlight service. You can open the UI side of the Web page to view topologies and hosts.3. Create a new terminal, enter the./pox/pox.py Forwarding.hub to start the Monitoring setup link. The Pox controller can release the flow met

The database structure contains the following table.
The database structure is as follows:
All the network bridges created through OVS-VSCTL, network cards, are stored in the database, OVS-VSWITCHD will be based on the configuration of the database to create a
