Modern campus networks need to support multiple services at the same time, including office access, server room operations, video surveillance, wireless access, voice communication, IoT device access, and guest networks. Traditional flat Layer 2 networks are increasingly unable to meet long-term requirements for reliability, security isolation, service expansion, and operations management. As a result, enterprises need a high-speed, stable, secure, multi-service, easy-to-operate, and scalable LAN infrastructure.
Sino-Telecom campus network solution is designed for campus network deployment scenarios, covering five key areas: office areas, server rooms, surveillance areas, IoT device areas, and guest access areas. The network adopts an all-optical Ethernet switching architecture and uses a three-layer design consisting of the core layer, aggregation layer, and access layer to achieve high-speed interconnection, unified management, and service isolation.
Key Challenges in Modern Campus Network Deployment
With more services and devices running on the campus network, reliability, security, scalability, and O&M efficiency have become critical challenges:
High risk of service interruption: Office access, voice, surveillance, server room services, and IoT applications all depend on continuous network connectivity. Any failure in core devices or key links may affect multiple business systems.
Complex security isolation requirements: Office users, guests, cameras, IoT devices, and server room resources require different access permissions. Without clear isolation, the network may face unauthorized access and lateral movement risks.
Heavy deployment and O&M workload: Multiple access areas and a large number of devices make deployment and daily maintenance more complex, especially when the network architecture is unclear or device configuration is complicated.
Growing pressure for expansion: The continuous increase of terminals, APs, cameras, and IoT devices places pressure on port capacity, uplink bandwidth, and overall network scalability.
Cost control pressure: The customer needs to meet performance and reliability requirements while avoiding over-provisioning and unnecessary investment.

Comprehensive Security Control
Built-in security capabilities, including 802.1X authentication, MAC authentication, port security, ACLs, VLAN isolation, and user privilege management, help prevent unauthorized access, broadcast storms, DoS attacks, and abnormal traffic.
Advanced Service and QoS Capabilities
L2 to L4 packet filtering, traffic classification, rate limiting, port mirroring, and flexible queue scheduling allow critical services such as voice, video conferencing, and surveillance traffic to be prioritized in multi-service campus scenarios.
IPv6-Ready Architecture
Comprehensive IPv6 capabilities, including IPv6-based management, access control, multicast, DHCPv6, MLD, RIPng, OSPFv3 and BGP4+ features, provide a solid foundation for future IPv6 service evolution.
Simplified and Secure O&M
Multiple management and monitoring methods, including CLI, Web management, SNMP, Telnet, SSH, Console access, and traffic mirroring, make daily operations, fault diagnosis, and network optimization more efficient.
Green and Energy-Efficient Design
Efficient power conversion, intelligent power monitoring, flexible AC/DC/HVDC power options, and IEEE 802.3az Energy Efficient Ethernet support help reduce power consumption and improve overall network efficiency.
