5G network: that is, the fifth Generation Mobile Communication Technology (5th Generation Mobile Communication Technology, abbreviated as 5G) is a new Generation broadband Mobile Communication Technology with the characteristics of high speed, low time delay and large connection, and is a network infrastructure for implementing man-machine interconnection. The International Telecommunications Union (ITU) defines three major application scenarios of 5G, namely enhanced mobile broadband (eMBB), ultra-high reliability low latency communication (urrllc) and mass machine type communication (mtc). Enhanced mobile broadband (eMBB) is mainly oriented to the explosive growth of mobile internet traffic, and provides more extreme application experience for mobile internet users; the ultra-high reliable low-delay communication (uRLLC) mainly faces to the application requirements of the vertical industry with extremely high requirements on delay and reliability, such as industrial control, telemedicine, automatic driving and the like; mass machine type communication (mMTC) mainly faces to the application requirements of smart cities, smart homes, environment monitoring and the like which aim at sensing and data acquisition. In order to meet the requirement of 5G diversified application scenes, the key performance indexes of 5G are more diversified. ITU defines eight key performance indexes of 5G, where high speed, low latency, and large connection become the most prominent features of 5G, user experience speed reaches 1Gbps, latency is as low as 1ms, and user connection capability reaches 100 ten thousand connections/square kilometer.
Bridge (Bridge): frame forwarding two-port two-layer network equipment; a bridge, also called a bridge, is a store/forward device that connects two LANs, and can divide a large LAN into multiple segments, or interconnect more than two LANs into a logical LAN, so that all users on the LAN can access the server.
The most common method of extending a local area network is to use a bridge. The simplest bridge has two ports, and more complex bridges may have more ports. Each port of the bridge is connected to a network segment.
ebtables: a linux kernel bridge firewall tool; specifically, the Ebtables is a linux kernel firewall configuration tool, is specially used for controlling and screening the flow of the bridge interface for the linux system kernel, and can control the take-over of the ARP protocol by the bridge interface;
VXLAN (Virtual eXtensible Local Area Network ): the method is used for realizing two-layer network expansion penetrating through a three-layer network; in addition, the VXLAN technology is a virtual network technology with two layers, and the main principle is to introduce an outer tunnel in UDP format as a data link layer, and the original data message content is transmitted as the tunnel payload.
