Classification of industrial routers

Classification of industrial routers

　　(1) From the perspective of architecture, routers can be divided into the first-generation single-bus single-CPU structure industrial router, the second-generation single-bus master-slave CPU structure industrial-grade router, and the third-generation single-bus symmetric multi-CPU structure industrial-grade router , The fourth-generation multi-bus multi-CPU structure industrial router, the fifth-generation shared memory structure industrial 4G router, the sixth-generation crossbar architecture industrial-grade 4G router and the industrial wireless router based on the cluster system.

 (2) According to functions and service objects, industrial routers can be divided into "backbone routers", "industrial routers" and "access-level routers". "Backbone industrial router" is the key equipment to realize enterprise-level network interconnection, with large data throughput and strong functions; "enterprise-level router" is mainly used to connect the internal LAN and external wide area network of the enterprise, that is, as the internal enterprise Use as a gateway between the Internet and the external network; "Access-level routers" are mainly used to connect small business customer groups within homes or ISPs, and play a role in connecting a small number of user terminals that use private IP addresses to the Internet.

　　(3) According to the performance grade, routers can be divided into high, medium and low-grade dual-card routers. At present, industrial-grade 4G routers with throughput greater than 40Gbps are usually called high-end industrial 4G routers, industrial routers with throughput between 25 and 40 Gbps are called mid-range industrial 4G routers, and full Netcom routers with throughput less than 25 Gbps are called low-end full-network routers. router.

　　(4) According to the network location, it can be divided into "border industrial 4G router" and "intermediate node router". "Border industrial router" is at the edge of the network and used to connect with industrial routers of other networks. It has the characteristics of wide range of supported network protocols and routing protocols, high backplane bandwidth, and large throughput capacity; "intermediate node industrial LTE router" is at the The internal part of the enterprise network is usually used to connect different network segments of the same type of network, which acts as a bridge for data forwarding.

　　(5) According to forwarding performance, all Netcom routers can be divided into "wire-speed industrial-grade all Netcom routers" and "non-wire-speed industrial all Netcom routers". The so-called "wire speed" is to carry out smooth transmission completely in accordance with the bandwidth of the transmission medium, basically without interruption and delay.

　　(6) According to the structure, industrial TD-LTE routers can be divided into "modular full Netcom industrial routers" and "non-modular full Netcom industrial routers". Modular whole-network industrial routers have many slots and flexible structure. You can expand the port types and numbers of industrial-grade routers in the whole network by inserting boards with different functions in the slots; non-modular routers can only provide fixed ports .
