Introduction

Today, enterprises are accelerating digital transformation and business expansion. This places significant pressure on campus networks.

A growing number of endpoints connect to the network at the same time, which increases the risk of congestion. Applications such as video conferencing and large-scale data transfer require much higher bandwidth. During mobile office scenarios, wireless roaming performance is often unstable. Users may experience packet loss, session drops, or high latency. Network operations and maintenance are also becoming more complex.

Traditional network architectures can no longer meet enterprise requirements for high performance, high availability, and simplified management. As a result, the Integrated Wired and Wireless Network Solution has emerged.

This solution is built on a Spine-Leaf architecture and leverages Anycast technology. It enables enterprises to build an open network designed for ubiquitous compute resources. The architecture addresses scalability, reliability, and operational challenges in modern enterprise networks.

Four Core Challenges in Traditional Enterprise Networks

During enterprise digital transformation, the upgrade of endpoints and business applications continues to increase network load. The limitations of traditional network architectures are becoming more apparent. These challenges are mainly reflected in four areas:

  1. High-density access congestion: An average of two to three endpoints per user has become common. In centralized access scenarios, network congestion is severe. Traditional architectures lack sufficient forwarding capacity.
  2. Surging bandwidth demand: High-traffic applications such as video streaming, online collaboration, live broadcasting, and large-scale data transfer are widely deployed. Enterprise bandwidth requirements are increasing rapidly.
  3. Roaming and coverage issues: In complex environments, signal interference is frequent. Roaming convergence latency is high, and session drops occur regularly. Wireless user experience is significantly degraded, which impacts mobile productivity.
  4. Complex operations and maintenance: Multiple dormitory buildings, a large number of APs, and dynamic user environments increase the difficulty of configuration, monitoring, and troubleshooting. OPEX remains high.

To address these challenges, the Integrated Wired and Wireless Network Solution is built on a Spine-Leaf architecture. It integrates switching infrastructure and intelligent control technologies to enable deep convergence of wired and wireless networks. The solution delivers end-to-end connectivity across diverse enterprise scenarios.

Key Technologies to Build a Highly Available Enterprise Network

The core advantage of the integrated wired and wireless architecture relies on multiple industry-proven technologies. These technologies optimize roaming performance, channel utilization, traffic forwarding, and security enforcement. The goal is to enhance the integrated wired and wireless network performance and user experience.

1. Leading 10 ms Roaming Latency

To address roaming challenges, the solution integrates IEEE 802.11k, IEEE 802.11v, and IEEE 802.11r fast roaming mechanisms. It is combined with a distributed gateway architecture. Users can transition between APs without noticeable interruption.

  • 802.11k: Enables the client to make optimized roaming decisions before handoff, reducing blind scanning time and improving transition efficiency.

  • 802.11v: The AP proactively monitors client RSSI and local load conditions. It steers clients with weak signal quality to a better candidate AP by sending a BSS transition request.
integrated-wired-and-wireless-network-802.11v
  • 802.11r: Pre-establishes encryption keys so that full authentication is not required when roaming to a new AP. This significantly reduces handoff latency (typically ≤10 ms) and ensures uninterrupted real-time services.

  • Distributed Gateway: Gateway functions are deployed on each Leaf switch, improving stability and supporting concurrent roaming across the integrated wired and wireless network. This achieves an average handoff latency ≤10 ms, with zero packet loss, providing seamless connectivity during client mobility.

The solution also applies device-specific optimizations for Apple, Android, and Windows endpoints. It tunes roaming thresholds and scan timing to precisely accommodate different client types, ensuring an optimal roaming experience in multi-device enterprise environments.

2. Always Keep Clients on the Optimal Channel

The solution uses intelligent channel optimization to plan and dynamically adjust wireless channels, minimizing interference at the source:

  • Optimization Timing: Automatic tuning when an AP first comes online, scheduled tuning at 3 AM daily (configurable), and manual tuning by administrators.
  • Optimization Logic: The system scans channels and monitors AP load to automatically select idle channels. APs switch in real time to the optimal channel, ensuring stable wireless signals and consistent coverage.

3. Broadcast/Multicast-to-Unicast Conversion

To address the impact of low-rate broadcast and multicast traffic on wireless channel efficiency, the solution implements broadcast/multicast-to-unicast conversion:

  • Encapsulates traditional broadcast and multicast frames into unicast frames, reducing AP air interface resource usage.
  • Sends unicast packets at the optimal rate based on each client’s signal quality, significantly improving wireless throughput and mitigating latency or stuttering in high-traffic applications.

4. High-Reliability Networking and Traffic Forwarding

  • BGP EVPN: Enables Layer 3 dynamic routing and full-network ECMP load balancing. Routes are quickly withdrawn after client roaming, ensuring routing stability.
  • MC-LAG Support: Provides cross-device link aggregation. In server zones, dual-homed MC-LAG uplinks ensure no single point of failure for critical traffic.
  • Forwarding Optimization: Features such as VLAN broadcast suppression, strict AP forwarding, and ARP proxy reduce unnecessary traffic and improve forwarding efficiency.

5. Multi-Layer Security Protection

The solution establishes an end-to-end security framework, covering access security, user-based controls, and network segmentation:

  • Access Security: Implements IPSG, DAI, DHCP Snooping, and 802.1X to ensure only legitimate devices can connect.
  • Access Control: ACL policies can be configured on Spine and Leaf nodes to control user or subnet permissions, e.g., restricting certain users from accessing the server zone.
  • Network Segmentation: Guest networks are isolated in separate VLANs. ACL policies ensure guests can access only the Internet, without reaching internal core resources.
  • Distributed Gateway Security: Different service zones—user, server, and administrative networks—are finely segmented. Each zone has dedicated gateways and subnet masks, isolating traffic at the source.

Multi-Scenario Deployment Best Practices

This solution has been deployed and validated in an enterprise office environment, achieving 384 days of stable operation. The overall integrated wired and wireless network design addresses the distinct requirements of user and server zones, while enabling multi-floor interconnection and unified management. Key deployment highlights include:

  1. Network Architecture: The user zone uses a full Layer 3 Spine-Leaf design. The server zone adopts dual-homed MC-LAG uplinks. Server traffic bypasses the firewall for full-line-rate forwarding, improving data transfer efficiency.
  2. Wireless Deployment: APs are deployed in a W-shaped pattern across office areas. Each floor has 21 APs spaced approximately 10 m apart. Transmit power is set to 8 dBm, combined with automatic channel planning, ensuring seamless high-quality coverage.
  3. Multi-Floor Interconnection: Floors are connected via 10 G fiber links. eBGP routing and VRRP virtual IPs are used to enable efficient cross-floor traffic forwarding. For example, traffic from the 6th floor can reach the Internet via the 18th-floor gateway, with flexible bandwidth allocation.
  4. Device Specifications: Hardware selection is based on enterprise scale. CX308P-48Y-M-H serves as the Spine switch, CX204Y-48GT-M-SWP4 as the User-Leaf switch, and AP6020 as the wireless access point. This ensures a balance between performance and cost-effectiveness.
  5. Scalability: The user network supports up to 2 Spine switches connecting 48 Leaf switches, accommodating up to 96,000 endpoints. The server network supports up to 2,304 endpoints, allowing flexible adaptation to enterprise growth.
