Basic concepts and functions of routers
1. Definition
A router is a network device used to forward data packets between different networks (such as home networks, enterprise networks, or the Internet). Its core function is to connect multiple networks (such as LAN and WAN) and select the optimal transmission path for data packets through routing selection algorithms.
2. Core functions
●Path selection (Routing): Determine the data transmission path based on routing tables and algorithms (such as OSPF, BGP).●Packet forwarding (Forwarding): Forward data from the input interface to the correct output interface.
●Network address translation (NAT): Convert private IP to public IP to enable multiple devices to share a public address.
●Firewall and security: Filter malicious traffic through ACL or firewall functions.
●Wireless access (Wi-Fi): Home routers usually integrate wireless APs to provide Wi-Fi connections.
Hardware composition of routers
1.Central processing unit (CPU): Performs routing protocol calculations and configuration management.
◆Home routers: low-power ARM/MIPS chips.
◆Enterprise-level routers: high-performance multi-core processors (such as Cisco ASIC).
2.Memory:
◆RAM: stores runtime data such as routing tables (lost in case of power failure).
◆Flash: saves operating system images and configuration files.
3.etwork interface:
◆WAN port: connects to external networks (such as ISP lines).
◆LAN port: connects to local devices (supports PoE power supply).
◆Wireless module: supports 2.4GHz/5GHz frequency bands.
4.Switch chip: accelerates data exchange within the LAN.
5.Power module: external adapter for home use, redundant power supply for enterprise use.
Core categories of routers
1.Home routers
◆Features: covers small and medium-sized households, supports Wi-Fi 5/6, integrated parental control, QoS optimization.
◆Representative models: TP-Link Archer series, Huawei AX3.
2.Enterprise-level routers
◆Features: high concurrent connections, VPN support, multi-WAN port load balancing.
◆Representative models: Cisco ISR, Huawei AR series.
3.Mesh router
◆Features: Multi-node networking, seamless coverage of large apartments.
◆Representative models: Netgear Orbi, ASUS ZenWiFi.
4.5G mobile router
◆Features: Insert SIM card to provide mobile network, strong portability.
◆Representative model: Huawei 5G CPE Pro.
5.Industrial router
◆Features: Dustproof and waterproof, suitable for IoT and remote monitoring.
◆Representative model: Sierra Wireless IX20.
