Suppose there is a multinational company ABC, its headquarters is located in the United States, the branches are distributed in China and Europe, the company often conducts internal cross-border video conferencing, but due to network latency and bandwidth limitations and other factors, video conferencing is often lagging and blurred picture problems.

Before networking, ABC company’s network architecture is the traditional MPLS leased line, each branch is connected to the headquarters of the data center, video conference data needs to be transmitted through the MPLS leased line, due to the cross-border transmission of large amounts of data, network latency is high, resulting in video conferencing is unstable, and often lagging and blurred picture phenomenon, which affects the effect of the meeting and the efficiency of communication.

In order to solve the problem of lagging in cross-country video conference, ABC decided to adopt SDWAN networking. SDWAN networking technology optimizes the transmission of video conference data through intelligent routing, traffic optimization, and edge caching to improve the stability and quality of video conference.

1. Intelligent routing:

ABC has deployed SDWAN devices in each branch and headquarters. SDWAN technology can monitor network conditions in real time, including latency, packet loss rate and other indicators. When a videoconference begins, SDWAN selects the best network path to avoid congestion and delays, ensuring that videoconference data can be transmitted efficiently.

2. Traffic optimization:

SDWAN can optimize videoconferencing data and prioritize the transmission of critical data. In cross-country videoconferencing, real-time is very important. SDWAN can identify and prioritize video traffic to ensure stable and smooth videoconferencing.

3. Edge caching:

ABC deploys edge caching technology on SDWAN devices in each branch office. When videoconferencing data is cached on the servers of the nearest branch office, users participating in the conference can access the data faster, reducing network latency and improving user experience.

After networking, ABC Company found that the effect of cross-country videoconferencing was significantly improved, and the problems of lagging and blurred images were greatly reduced. The specific comparison is as follows:

1. Videoconferencing stability:

Before networking, video conferencing often suffered from lagging and blurred images, which affected the meeting effect and communication efficiency; after networking, through SDWAN’s intelligent routing and traffic optimization, video conferencing became more stable, lagging phenomenon was obviously reduced, and the images were clearer.

2. Delay reduction:

Before networking, cross-country transmission leads to high network latency, which affects the real-time performance of video conference; after networking, SDWAN optimizes the network path and reduces the latency, so the real-time performance of video conference is improved.

3. User experience:

Before networking, videoconferencing is unstable and user experience is poor; after networking, SDWAN edge caching technology accelerates data transmission, users can get data faster and user experience is improved.

In summary, through SDWAN networking, ABC successfully solved the lagging problem of cross-country videoconferencing, and the stability and quality of videoconferencing was significantly improved. SDWAN networking’s intelligent routing, traffic optimization, and edge caching provide more stable, efficient and effective solutions for cross-country SDWAN networking technologies, such as intelligent routing and traffic optimization and edge caching, provide more stable, efficient and high-quality network services for transnational videoconferencing, which promotes the efficiency of the company’s internal communication and globalization.
