Kabel połączeniowy Plug And Play wykorzystuje samochód / Dane zewnętrzne. Cena w Internecie

Podłącz i graj (PnP) pierwotnie było określeniem sprzętu komputerowego. Odnosi się do możliwości automatycznego wykrywania zasobów sprzętowych w momencie dodania nowego urządzenia zewnętrznego do samochodu lub komputera, bez konieczności rekonfiguracji lub ręcznej instalacji sterowników. Później, zaczęło to również oznaczać kable z możliwością podłączenia na gorąco, co oznacza bezpośrednie dodawanie lub usuwanie urządzeń sprzętowych, gdy komputer jest włączony, jak podłączanie i odłączanie USB.
In the field of data communications, in network solutions, plug-and-play wiring harnesses refer to network devices and access terminals that can automatically access the network to complete configuration and deployment without manual configuration after accessing the network.

Why does the campus network need plug-and-play wiring harnesses?
With the rapid development of network technology, the scale of enterprise networks is also expanding. Enterprise customers need to manage and maintain hundreds to thousands of devices. The work consumed in the early planning and deployment stages, such as the initial installation and configuration of equipment, and equipment upgrades, accounts for one-third or even longer of the entire network management and operation cycle, and most of these tasks are simple and repetitive labor. Therefore, customers are increasingly eager to simplify the installation of network equipment, deployment period management, and subsequent equipment software upgrades to improve efficiency.

In addition, with the continuous popularization and application of the Internet of Things, the types and number of terminals accessing the campus network are increasing. Especially in large and medium-sized campus networks, in addition to PCs and mobile phones, there are also dumb terminals such as IP phones, printers, and IP cameras. A large number of different types of terminals need to be connected to the campus network, which brings great difficulty to the management of the campus intranet terminals. Because the traditional network management system can only view the IP and MAC of the access terminal, it is impossible to manage the terminal more finely. If different types of terminals need to be planned and deployed, different network services and policies need to be deployed. The administrator needs to manually configure each type of terminal according to the plan, and the service configuration is complex and the operation is cumbersome. Automatic identification of terminal equipment and plug-and-play connection cables are also urgently needed.

The new generation of automated plug-and-play connection cable solutions is designed to help users simplify the network installation process, and provide automated deployment services for networks that need to be newly deployed through SDN controllers. It also realizes the seamless combination of pre-network deployment planning and post-network maintenance, greatly improving the efficiency of network management and operation and maintenance. It effectively reduces labor and time costs and has the following advantages:

Visualization: The operation process of network administrators and installation engineers is a full-graphic operation interface, including: visualization of the configuration interface and visualization of network planning.
High efficiency: By pre-deploying services on the SDN controller (such as the iMaster NCE-Campus controller), the end-to-end process can be shortened during the actual deployment process. Manual deployment that used to take several days can now be completed in a few hours.
Fewer errors: All configurations are done through graphical operations on the SDN controller, reducing the probability of errors in command line configuration. Connection errors can be perceived in real time through the SDN controller for quick troubleshooting.

What is the plug-and-play process for network devices?
Taking switches as an example, in the cloud campus network, the network is designed in a hierarchical tree shape, and there are many switches below the core layer. Plug-and-play of aggregation and access layer switches can improve deployment efficiency and simplify deployment workload.

The core layer switch completes the southbound connection with the SDN controller through the command line, and then uses the core layer switch as the root device of the management subnet. The switches below the core layer are put online on the SDN controller through DHCP, realizing plug-and-play of switches below the core layer.

As shown in the figure above, the plug-and-play process of the aggregation switch SwitchA is as follows:

The administrator deploys the DHCP server function on the core layer device (it can also be a separate DHCP server device in the network), enables the DHCP function on VLANIF1, and configures the DHCP Option 148 option. It contains the NETCONF enablement status of the device, the URL/IP and port number information of the SDN controller.

After the core layer switch SwitchA is started with an empty configuration, it will use VLANIF1 to actively initiate a request to the DHCP server by default.

Since all ports of the switch are added to VLAN 1 by default when it leaves the factory, the core switch and the switch that initiates the request can communicate with each other in VLAN 1.

After receiving the request, the core switch as the DHCP server will respond to the switch SwitchA with a DHCP message carrying the Option 148 option.

According to the content of the Option 148 option, the switch SwitchA enables the NETCONF function and obtains the URL/IP and port number information of the SDN controller.

After the switch SwitchA obtains the URL/IP and port number information of the SDN controller, it will use the URL/IP and port number information of the SDN controller to register and authenticate with the SDN controller.
After the switch SwitchA is registered and authenticated on the SDN controller, the SDN controller will automatically send the configuration to SwitchA according to the pre-configuration set by the administrator (including PnP VLAN), complete the start of SwitchA, and achieve plug-and-play.

In the plug-and-play process of network devices, there is an important concept, PnP VLAN, also called auto-negotiation management VLAN, which refers to the VLAN used when the SDN controller manages switches or APs.

Initially, the aggregation switch and access switch use functional VLAN 1 to register and go online with the SDN controller. To improve network reliability, administrators generally do not use VLAN 1 as the management VLAN, because VLAN 1 is the default VLAN of the switch, and all ports of the switch are added to VLAN 1 by default, so VLAN 1 is more likely to generate broadcast storms, affecting business communications. Therefore, after the aggregation switch and access switch go online using VLAN 1, they need to automatically switch to the set management VLAN according to the SDN configuration. This automatically switched management VLAN is called PnP VLAN.

In the campus network, in order to facilitate network maintenance, the PnP VLAN used by the wired network and the wireless network are generally set to different VLANs, which are called wired PnP VLAN and wireless PnP VLAN respectively. The PnP VLAN used by the switch is called wired PnP VLAN, and the VLAN used by the AP is called wireless

The PnP VLAN switching process is as follows:
The aggregation device and access device use VLAN 1 to register and go online on the SDN controller.
The SDN controller sends the pre-configured PnP VLAN to the aggregation device and access device.
The aggregation device and access device re-register and go online using the negotiated PnP VLAN to achieve plug-and-play.

What is the plug-and-play process of the access terminal?
The specific process is shown in the figure below. Plug-and-play of terminal devices includes: terminal identification and terminal anomaly detection.

Network operation and maintenance personnel pre-deploy known terminal fingerprint libraries and terminal type policies in iMaster NCE-Campus.
When a terminal accesses the network, the device automatically extracts the terminal’s fingerprint and reports it to iMaster NCE-Campus.
The management system identifies the terminal type based on the terminal fingerprint and issues policies based on the terminal type to achieve plug-and-play of terminal devices and improve terminal access efficiency.
For unknown type terminals, when the terminal accesses the network, terminals of the same type are automatically identified through AI clustering learning and automatically access the network through manual labeling in the intelligent management and control system. After the terminal accesses the network, the device detects the terminal’s traffic in real time. When the device detects that the terminal traffic is too large or the terminal IP/MAC is repeated through intelligent analysis, it automatically issues an isolation policy to the abnormal terminal.
