At present, the University maintains a total Internet bandwidth of 18 Gbps, supporting high-speed connectivity for academic and administrative operations. Most users access the Internet via two local Internet service providers (ISPs), each offering distinct paths to ensure redundancy and reliability.

In addition to general Internet access, there is a dedicated leased line connection to InforMac, which facilitates secure and efficient communication with government services and public administration systems.

To support cross-border connectivity, the Transitional Research and Education Site in the Guangdong-Macao In-depth Cooperation Zone in Hengqin is equipped with an International Private Leased Circuit (IPLC). This dedicated link ensures stable and high-performance communication between the site and the main University network in Macao, enabling seamless access to shared resources and services.

Each computer that connects to the Internet requires a valid IP address. ICTO is responsible for assigning IP addresses and managing Domain Name System (DNS) registration for all University-owned Internet servers.

To safeguard the network and optimize bandwidth usage, ICTO has also deployed various network devices and services, including firewalls, secure email gateways, and Internet access management systems.

To optimize bandwidth usage, ICTO has introduced an Internet Access Management System guided by the following principles:

• Academic Priority: Teaching, research, and administrative activities are prioritized.
• Fair Usage: Bandwidth is allocated based on essential needs.
• Tiered Management: Network applications are managed with differentiated strategies.
• Resource Optimization: Technology and management practices maximize bandwidth efficiency.
• Security and Compliance: Network safety and legal compliance are ensured.

• Internet Bandwidth Management Strategy For Residential Areas
• Transitional Research and Education Site
• High Speed Network For Research
• Procedures of Applying Network Connection and Domain Name for Servers
• SSL VPN Service

The use of Internet Service is governed by the Acceptable Use Policy and Campus Network Rules:

• ICTO.04/201210/001.r00 – Acceptable Use Policy on ICTO Computing Facilities Campus Network and Internet
• ICTO-IUS.04/200809/001.r00 – Campus Network Rules
