OverviewA virtual device is an abstraction built on one or more real devices. The correspondence between a virtual device and a real device is many-to-many, but not all combinations can be defined or supported by the kernel. Some of the more common virtual devices are listed below:Bonding //bindings, virtual devices bind physical devices so that they are like a single device 802.1Q //ieee standard for establishing a virtual representative of vlanbridging//bridge aliasing interfaces / /a

Datax,Data PackageThe minimum data transmission unit in the package switched network.
Rfc_1594 defines a data package as follows: a self-complete and independent data entity carries enough information. It can select a path from the source and finally reach the target computer, instead of relying on
"Accept data" protocol stack queue, it seems that the data is received from the network.

succeed.The preceding example shows that some SOCKS5 servers and SOCKS5 clients do not have a thorough understanding of the SOCKS5 protocol. Even if SOCKS5 is used, communication will be poor when interworking with iptables.In another example, the SOCKS5 server is located on the public network. The intranet client first performs Nat through iptables and then connects to the SOCKS5 server.Reference the following text in the SOCKS5 protocol (rfc1928:The UDP associate request is used to establish

In encapsulation and interfaces, the private keyword encapsulates an internal member of an object. Encapsulated, the product hides the internal details and is provided only to the user interface (interface). Interfaces are very useful concepts that can assist in our abstract thinking. In real life, when we think of an appliance, we often think of the functional interface of the appliance. For example cups,
at the end of 2013, it further expands the comprehensive portfolio of Oracle products in application, social networking, platform and infrastructure services. At the same time, Oracle recently released a series of cloud-oriented Database and software integration products, including Oracle Database 12c) oracle SuperCluster M6-32 Integration System Oracle SuperCluster M6-32 Engineered System), Oracle Virtual computing device Oracle Virtual Compute Appliance
virtual device is a pre-configured virtual environment that minimizes the work required for normal operation. You do not need to install the operating system, install software, and execute software configurations in this environment. It is pre-configured and can be used at any time. IBM DB2 Enterprise 10.1 Trial Virtual Appliance can run locally on the host computer Through VMware Workstation/Player, or remotely in a VMware vSphere environment. After
The command pattern emphasizes the encapsulation call , which encapsulates the method invocation. By encapsulating the method call, we can encapsulate the operation block, so the object that calls the operation does not need to be concerned about how things work, they just need to know how to use the wrapping method to do it. By encapsulating the method call, we can also do some very clever things, such as logging, or reusing these packages to implement revocation.We use the following example to
The instructions must be executed by specifying the disk device to be checked and the number of disk blocks for the appliance.
