Hetao Shenzhen-Hong Kong Science and Technology Innovation Co-operation Zone Research Dedicated Line Guide: Shenzhen-Hong Kong Inter-Park Connectivity, Research Data Transfers, and Overseas AI Access

Just across the river: where daily research collaboration between the Shenzhen and Hong Kong parks gets bogged down

At many research groups, joint laboratories, and R&D centres in Hetao, site IT is managed alongside other duties by a research director or administrative lead without a dedicated on-site network engineer. Even though the Shenzhen park and the Hong Kong park are separated only by the Shenzhen River, teams collaborating between the two parks—or with local universities and research institutes in Hong Kong—most often run into unstable mutual access to internal systems first. Research group members in the Shenzhen park need to log in to laboratory management platforms, code repositories, and shared document libraries in the Hong Kong park or at Hong Kong partner institutions, while researchers on the Hong Kong side need on-demand access to data backends or remote connections to laboratory hosts in Shenzhen. When traffic crosses the border directly over the public internet, cross-border egress congestion between different carriers, circuitous routing, or evening peak fluctuations frequently cause laggy remote interfaces, system pages that take ages to open, or scheduled synchronisation jobs that time out mid-run.

Another common frustration is slow and easily interrupted cross-border transfers of research datasets and large files. Joint research projects regularly require passing high-resolution experimental imaging, analysis sample archives, simulation results, or large literature collections back and forth between Shenzhen and Hong Kong. Over standard public internet connections, throughput fluctuates widely during long transfers of large files, and a single mid-transfer drop often forces a restart from the beginning. Meanwhile, continuous transfers of large datasets easily saturate the laboratory's local broadband, slowing down video calls and everyday web browsing for everyone else at the site.

At the same time, access to international academic resources and overseas AI services is often inconsistent. In their daily work, researchers search international academic databases, visit overseas open-source communities and collaboration platforms, and frequently rely on overseas AI tools such as Claude, ChatGPT, and Gemini to review foreign-language literature, assist with writing experimental scripts, or organise multilingual materials. When a site lacks unified cross-border connectivity, whether researchers try to connect directly from the Shenzhen park or piece together individual workarounds on their own, they frequently encounter failed page loads, long responses that freeze halfway through generation, or API call errors. Keep in mind that slow access or errors sometimes stem from cross-border public internet congestion, and at other times from laboratory LAN bandwidth being saturated by large file transfers or peak-hour rate limiting on the target academic platform or AI service itself—so a single episode of lag should not be automatically attributed to a specific link failure. If your team also interconnects GPU clusters and syncs model training datasets between Shenzhen and Hong Kong, see our Hetao Dedicated AI Compute Network Guide; if your partner sites also span other Greater Bay Area cities such as Guangzhou, Dongguan, or Zhuhai, see our Guangdong-Hong Kong-Macao Greater Bay Area Research Dedicated Line Guide.

Building a research dedicated line over existing broadband in both parks with nearby access in Hong Kong for smooth overseas AI use

Built around the connectivity needs linking the Hetao Shenzhen park, the Hong Kong park, and partner institutions in Hong Kong, we provide Enterprise Facility Interconnect and Dedicated Compute Network transmission services. Without modifying your laboratory's existing research software, we help institutions connect sites on both sides and external resources in four ways:

• Connect over existing broadband in Shenzhen and Hong Kong without waiting for cross-border physical line construction: Offices and laboratory sites in the Shenzhen park and the Hong Kong park use their existing internet broadband to connect to the nearest PoP (point of presence) on our network without laying new cross-border physical dedicated lines, provisioning faster than traditional carrier dedicated lines. As joint projects expand their teams, add laboratory instruments, or enter intensive data transfer phases, channel bandwidth can be scaled on demand at any time.
• Connect to our SD-WAN network in Hong Kong to reach Claude, ChatGPT, and Gemini smoothly over a dedicated channel: Institutions can connect to the nearest PoP on our SD-WAN network in Hong Kong to smoothly access AI services such as Claude, ChatGPT, and Gemini over a dedicated channel while maintaining stable access to international academic resources and overseas collaboration platforms. We configure destination-based routing policies that direct overseas AI chats, API calls, and international academic search traffic through the dedicated transmission channel while keeping everyday local government portal, finance, and general office web traffic on each site's existing local broadband without mutual interference (for more details on accessing overseas AI services from Hong Kong sites, see our guide to AI service access for Hong Kong businesses).
• Bidirectional dedicated cross-border channel for research data and internal system access: The transmission channel fully supports TCP, UDP, and HTTP(S) protocols for bidirectional access across the Shenzhen park, the Hong Kong park, and Hong Kong partners. Whether researchers are logging in to internal management systems at a partner lab across the river in real time, connecting remotely to laboratory equipment, or continuously transferring research datasets and large files between storage nodes on both sides, everything is carried reliably over the same dedicated channel with bandwidth allocated by business priority so large file transfers do not crowd out daily online collaboration and AI tool usage.
• Plug-and-play preconfigured hardware on site and virtual gateways for cloud environments: For offices and laboratory sites, we provide preconfigured physical access appliances that on-site staff can bring online simply by plugging in power and Ethernet cables, with no dedicated network engineer required on site for commissioning. If your institution hosts research systems or analytics environments on a public cloud or virtualisation platform, we can deploy virtual gateways directly to link cloud resources with laboratories in both the Shenzhen and Hong Kong parks on the same network (for everyday multi-site networking approaches, see our Multi-Site Enterprise Networking Guide).

How responsibilities are divided between on-site resources and network services, and what to prepare for your initial consultation

When preparing sites in both parks or launching joint projects, many Hetao research teams rely on research secretaries, administrative managers, or part-time IT staff to coordinate with external service providers—making a clear division of responsibilities and straightforward day-to-day coordination especially important.

When consulting with us, you do not need to draw up detailed network topology diagrams in advance or ask technical staff to run packet captures or produce test reports beforehand. For our initial discussion, simply share a few basic details: where your sites in the Shenzhen park, the Hong Kong park, or Hong Kong partner institutions are located (and whether they are offices, laboratory server rooms, or public cloud environments); what daily collaboration activities and data flows your team runs (such as which internal systems are accessed across sites, what types of research files are transferred, and which international academic databases or AI services like Claude, ChatGPT, and Gemini are needed); and the general state of existing broadband at each location. Once we understand your setup, we will work with you to confirm a suitable access plan based on your on-site conditions.
