Zoom video conference disconnection, how can the company adjust network equipment??? Solution//Global IPLC service provider of Shigeng Communication

一、In today's globalized world, Zoom video conferencing has become the "digital oxygen" for enterprise collaboration. However, when this' oxygen 'supply is unstable - with stuttering visuals, broken voice, and even sudden disconnections - it not only interrupts communication, but also has the potential to miss business opportunities, delay decision-making, and damage professional image. For IT managers, Zoom disconnection issues have escalated from technical failures to business risks that affect core operations.

The root of the problem is often not singular, but lurking at various levels of the enterprise network architecture, like a complex "disconnection pyramid". This article will provide a systematic network equipment adjustment plan for enterprises, from terminal to cloud, from passive response to active prevention, aiming to completely end the stability problem of video conferencing.

First layer: Strengthen the foundation of the local network and eradicate the "conference room dilemma"

When the disconnection issue only occurs in specific conference rooms or office areas, the problem usually lies in local network devices and access environments. This is the quickest and most effective layer to solve the problem.

1. Ending the tragedy of wireless: implementing the iron law of "wired priority"

The inherent shortcomings of wireless networks are the number one culprit for unstable meetings. Signal interference, bandwidth competition, and wall attenuation can all lead to the loss of critical data packets. For all fixed meeting rooms and important staff workstations, it is mandatory to deploy and prioritize the use of gigabit (Cat5e and above) Ethernet wired connections. A test showed that under the same network environment, the latency and packet loss rate of wired connections can be reduced by more than 80% compared to Wi Fi.

2. Innovate Wireless Access Points (APs): Embracing the Wi Fi 6 Era

For open office areas or flexible workstations that require wireless connectivity, routers that only support outdated 802.11n/ac standards must be phased out. Fully upgraded to an enterprise level AP that supports Wi Fi 6 (802.11ax). The three revolutionary technologies of Wi Fi 6 can accurately solve conference pain points:

OFDMA (Orthogonal Frequency Division Multiple Access): divides the wireless channel into multiple resource units, allowing one AP to simultaneously serve small traffic video packets from multiple participants, rather than queuing, significantly reducing latency. For example, after Cisco deployed in a certain university, the number of wireless conference lag complaints in high-density classrooms decreased by 92%.

MU-MIMO (Multi User Multiple Input Multiple Output): Supports AP to communicate with multiple terminal devices simultaneously, instead of alternating conversations, significantly improving the concurrency efficiency of multiple people attending meetings simultaneously.

BSS Coloring (Basic Service Set Coloring): Coloring signals from different APs to enable devices to effectively identify and ignore co frequency interference from neighboring areas, particularly in dense office environments.

3. Optimize the core gateway: enable intelligent traffic scheduling (QoS)

The key value of enterprise level routers lies in their intelligent control capabilities. Zoom traffic must be marked with the highest priority in the Quality of Service (QoS) settings of the router or firewall.

Specific operation: According to Zoom's official recommendation, add the IP address range (such as 162.255.37.0/24, etc.) and port (TCP 443, 8801-8810, etc.) it uses to the high priority policy. This ensures that in case of network congestion, routing devices will prioritize the release of video conference data packets like directing traffic, ensuring smooth meetings.

Layer 2: Refactoring Wide Area Network Arteries and Cracking the 'Cross border Pain'

When meetings between headquarters and overseas branches, as well as between home and office employees, frequently disconnect, the issue has escalated to the level of the enterprise wide area network (WAN). The traditional star shaped network architecture of "pulling all traffic back to the data center" is the root cause of high latency and packet loss in cross-border conferences.

1. Deploying SD-WAN: Building "Intelligent and Shortest" Transmission Paths

SD-WAN (Software Defined Wide Area Network) is the core device solution to address this issue. It deploys edge devices in various branch offices and intelligently manages multiple network links (such as MPLS dedicated lines, regular broadband, 4G/5G) through software defined methods.

Key role: The SD-WAN controller can monitor in real-time the latency, packet loss, and jitter of each link to Zoom cloud servers (usually in multiple regions around the world). For Zoom traffic, it can automatically select the link with the best quality and shortest path to directly enter the Internet, completely bypassing the congested international outlet of the headquarters. After deployment by a manufacturing enterprise, the delay of Zoom meetings between the US and China decreased from 380ms to 180ms, and subjective lag disappeared.

2. Enable cloud exchange and SaaS optimization

The advanced SD-WAN solution integrates dedicated line docking capabilities with mainstream cloud service providers such as AWS and Alibaba Cloud, and can identify thousands of SaaS applications (including Zoom). This means that Zoom traffic from branch offices can be directly and securely accessed to the nearest Zoom cloud portal through SD-WAN devices, optimized by the operator's backbone network, providing an experience comparable to local access.

Comparison of Upgrade Plans for Local and Wide Area Network Core Equipment

Optimization level target equipment upgrade plan and expected core value effects

Upgrade the local network wireless access point (AP) to an enterprise level Wi Fi 6 AP, utilizing OFDMA and MU-MIMO to address high-density access and interference. The stability of wireless meetings in a single office/conference room has been greatly improved, and there is no pressure for multiple people to attend simultaneously.

Enable and finely configure QoS policies for local network enterprise routers/firewalls, and mark Zoom traffic as the highest priority. Ensure smooth meetings even when network bandwidth is occupied by other applications such as downloads and backups.

Deploy SD-WAN devices at the edge of wide area networks, replace or upgrade traditional routers, and achieve intelligent routing and cloud acceleration. Thoroughly solve the latency and packet loss issues of cross regional and cross operator meetings, and enhance the global conference experience.

Third layer: Implement an active operation and maintenance system, transforming "firefighting" into "fire prevention"

The best adjustment is to prevent problems from happening. This requires the introduction of professional monitoring and management equipment to build proactive operation and maintenance capabilities.

1. Deploy Network Performance Monitoring (NPM) platform

Deploy probes or enable NetFlow/sFlow functionality at critical nodes in the network (core switches, egress routers, SD-WAN devices) to aggregate data into a unified network performance monitoring platform. This platform can visualize the path, latency, jitter, and packet loss rate heatmap of Zoom conference traffic across the entire network, achieving minute level fault localization.

2. Utilize the official Zoom diagnostic tool

For enterprises using Zoom Business Edition or above, it is essential to enable their Quality of Service Subscription. This is an irreplaceable management perspective. It can view the quality of every meeting of every user within the enterprise from the perspective of Zoom cloud, providing detailed indicator reports (such as audio/video packet loss rate), helping to quickly distinguish whether it is a user's local network problem or an overall company network problem.

Conclusion: From cost center to efficiency engine

The adjustment of enterprise network equipment to eradicate Zoom disconnection is far more significant than solving a technical malfunction. It is essentially a modern reconstruction of the enterprise's digital collaboration infrastructure. This investment directly translates into measurable business value: higher team collaboration efficiency, faster market decision-making speed, stronger global operational resilience, and a more professional corporate image.
