Basic LAN Concepts Local Area Network (LAN) is a data communication system interconnected by multiple computers and other network devices within a certain geographic area, which is mainly used to realize the functions of resource sharing, data transmission and cooperative work. LAN has the following characteristics: Fast transmission speed: The data transmission speed within LAN is generally between 10Mbp ~10Gbp, much higher than that of Wide Area Network (WAN) or Internet; Low latency: Data transmission latency within a LAN is generally at the microsecond level, much lower than that of a WAN or the Internet; High reliability: The reliability of data transmission within LAN is generally above 99.99%, much higher than that of WAN or Internet; Good security: The security of data transmission within LAN is generally guaranteed by physical isolation or encryption technology, which is much higher than that of WAN or Internet. Based on different network topologies, LANs can be categorized into the following types: (a) Bus-based LANs: All computers and network devices are connected to a common bus, through which data transmission takes place. This type of LAN is simple in structure, low in cost, and easy to expand, but is prone to problems such as conflicts, interference, and failures; Ring-type LAN: All computers and network devices are connected to a closed loop through which data is transmitted. This type of LAN structure is stable, reliable, and efficient, but is difficult to expand and complicated to maintain; Star type LAN: All computers and network devices are connected to a central node through which data transmission takes place. This type of LAN has a flexible structure Tree LAN: A hierarchical network structure consisting of multiple star-shaped LANs connected by a tree topology for data transmission. This type of LAN structure allows for large-scale network coverage, but the increased network hierarchy results in increased transmission delays and management complexity; Mesh-type LAN: All computers and network devices can be directly or indirectly connected to other devices for data transmission over multiple paths. This type of LAN structure allows for a high degree of redundancy and fault tolerance, but network configuration and routing is more complex. 2.2. SME Network Requirements Small and medium-sized enterprises (SMEs) are enterprises that are relatively small in terms of size, capital and personnel, and generally operate within a geographical area. SMEs have the following characteristics: Small size: Small and medium-sized enterprises (SMEs) generally range in size from 10 to 500 people, and are more flexible, agile and innovative compared to large enterprises; Less capital: the capital of small and medium-sized enterprises is usually between 100,000 and 50 million, which is more economical, efficient and reasonable compared to large enterprises; Fewer people: SMEs typically have between 10 and 500 people, making them simpler and more collaborative than larger organizations. According to different industries and business characteristics, the network needs of small and medium-sized enterprises are different, but can generally be summarized in the following areas: Network Performance: SMEs need a high-speed, low- latency, stable network system to support a wide range of internal and external data communications and application services; Network Security: Small and medium-sized businesses need a secure, trustworthy, and protected network system to protect their data assets and trade secrets from all kinds of cyber attacks and threats; Network Reliability: Small and medium-sized enterprises need a reliable, fault-tolerant, recovery network system to ensure that the enterprise's network services in the event of failure can resume normal operation in a timely manner; Network Economy: Small and medium-sized enterprises need an economical, frugal and optimized network system to reduce their network construction and operation costs. In summary, small and medium-sized enterprises need an efficient, secure, reliable and economical LAN networking solution to meet their different network requirements and characteristics. 3.

In order to design the high order router, then the microstructure is planned and optimized to carry out more functional design on limited space resources, and the circuit and logic design is simplified, and the wiring layout of the terminals should be reasonable and highly utilized. The HAC tile structure can satisfy the high space utilization and needs to be very good. The design principle of the HAC tile structure is actually very close to that of the asymmetric cross- small switches The 32-port router is eight 4×32 cross switches and also by the small can meet the 32×32 port setup requirements, while the structure design of 4×32 can be visually seen a lot simpler. Although there will be the requirements of the hardware computing power of the terminal processing system still feels complex. and then generalize it to the design concept of the HAC switch design conceptual structure of the design concept. the complex structure of the switch is further simplified and decomposed into multiple sub-switching units. 4. Design Principles A LAN is a network of computers and other network devices interconnected by switches, routers and other devices within a certain geographical area. LAN can realize the functions of resource sharing, data transmission, and communication and collaboration, and is the basis for the informationization construction of small and medium-sized enterprises. This paper introduces the design principles, steps, and examples of the LAN networking scheme for small and medium-sized enterprises based on Huawei communication equipment. Design Principles According to the enterprise's business needs, scale, budget and other factors, choose the appropriate network topology and equipment models to ensure the reliability, security, scalability and ease of management of the network. A layered network design model is used to divide the LAN into core, aggregation and access layers to achieve separation and optimization of network functions and improve network performance and efficiency. Reasonable planning of network address space, use of subnetting and virtual local area network (VLAN) technology to achieve logical division and isolation of the network and reduce broadcast storms and security risks. Using routing protocols and switching protocols, it realizes dynamic routing and load balancing at the network layer and link layer, and improves the network's adaptive and fault- tolerant capabilities. Security devices and technologies such as firewalls and intrusion detection (ID) systems are used to realize protection of network boundaries and internal monitoring to prevent malicious attacks and data leakage. Use management tools such as network management systems (NM) to configure, monitor, maintain, and troubleshoot network devices to improve network visualization and controllability. Design Steps: Analyze the business needs of the enterprise, determine the objectives and scope of the network, and develop a network design plan. Select the appropriate network topology, and determine the number, location, and connection methods of equipment in the core, aggregation, and access layers. Select appropriate equipment models, and choose Huawei switches, routers, and other communication equipment based on equipment performance, features, price, and other factors. Plan the network address space, assigning parameters such as IP addresses, subnet masks, and default gateways based on network size and segmentation. Configure network devices, according to the design scheme, perform basic and advanced configuration for each layer of devices, including interface settings, VLAN settings, routing settings, switching settings, etc. Configure network security, according to the security policy, perform firewall configuration, ID configuration, etc. on the network boundary and interior. Configure network management, according to the management requirements, perform NM configuration, NMP configuration, etc. for network devices. Test network function, according to the test plan, test and verify the connectivity, performance, security, etc. of the network. Optimize network operation, adjust and optimize the network according to the test results and operation conditions. Design Example: Assume that a small to medium-sized enterprise has 200 computers and 10 servers and needs to set up a local area network (LAN). The organization has three departments: sales, technology and property. The sales department needs to exchange data with external customers; the technology department needs to process data with internal servers; and the property department cannot collaborate with internal and external communications. The enterprise wants to use Huawei communications equipment to build an efficient, secure, and easy-to-manage LAN. Based on the business requirements of this enterprise, the following network plan can be designed: Network topology: A star topology is used to divide the network into the core layer, aggregation layer, and access layer. The core layer uses one Huawei series switch as the core device of the network, responsible for connecting the external network and convergence layer devices. The aggregation layer uses three Huawei 5700 series switches, corresponding to the three departments, which are responsible for connecting the core layer equipment and the access layer equipment. The access layer uses ten Huawei 2700 series switches to connect computers and servers in each department. 5.
