![]() ![]() ![]() Fiber-optic communication remains the medium of choice for Internet backbone providers for several reasons. Optical fiber trunk lines consist of many fiber cables bundled to increase capacity, or bandwidth. The Internet backbone consists of many networks owned by numerous companies. Routing of prominent undersea cables that serve as the physical infrastructure of the Internet. The largest providers, known as Tier 1 networks, have such comprehensive networks that they do not purchase transit agreements from other providers. In addition, the high degree of redundancy of today's network links and sophisticated real-time routing protocols provide alternate paths of communications for load balancing and congestion avoidance. The resilience of the Internet results from its principal architectural features, most notably the idea of placing as few network state and control functions as possible in the network elements and instead relying on the endpoints of communication to handle most of the processing to ensure data integrity, reliability, and authentication. ![]() The Internet, and consequently its backbone networks, do not rely on central control or coordinating facilities, nor do they implement any global network policies. Internet service providers, often Tier 1 networks, participate in Internet backbone traffic by privately negotiated interconnection agreements, primarily governed by the principle of settlement-free peering. These data routes are hosted by commercial, government, academic and other high-capacity network centers, as well as the Internet exchange points and network access points, that exchange Internet traffic between the countries, continents, and across the oceans. The Internet backbone may be defined by the principal data routes between large, strategically interconnected computer networks and core routers of the Internet. This is a small look at the backbone of the Internet. It does not store any personal data.Each line is drawn between two nodes, representing two IP addresses.

It allows campus network connections over a non-CUHK network (e.g. This includes Prince of Wales Hospital, Taipo Hospital, Lek Yuen Health Centre, Eye Hospital, School of Continuous Studies, School of Law and MBA Programme are connected to the Campus Network through Metro Ethernet link, and remote routers. It allows WiFi connections at different hotspots out of CUHK campus. CUHK Off Campus WiFi (CUHK Wi-Fi Hotspot Partnership Programme).It allows WiFi connections through 802.11a/ b/ g/ n / ac wireless LAN access points within CUHK campus. Each student hostel connects to Campus Backbone Network via 1 x 1GE or 2 x 10GE links.Įach classroom connects to Campus Backbone Network over a Gigabit Ethernet link and employs Virtual Private Network (VPN) technology to assure the security. We assist College/Postgraduate/Department Student Hostel Management to plan for their network connection. With 10GE inter-building links introduced, departments/units on main campus can also request for 10GE connections. We assist departments to plan and set up their Local Area Network (LAN). ![]()
