Based On The IRF Technical College Campus Network Design

The arrival of the information era, the network of popular campus network structures of more and higher requirements. The traditional sense of Fast Ethernet (Fast Ethernet using standard IEEE802.3u) and Gigabit Ethernet (Gigabit Ethernet rates using standard IEEE802.3z) to some extent can not meet the growing network groups and the growing network demands. In this context, Nantong a university campus to the new campus network to the original building and campus networks "Gigabit-10Gigabit " transformation. Based on the campus network construction projects as a backdrop to introduce campus network infrastructure to the project design, implementation and some of the key technology (emphasis on the company's Huawei IRF (Intelligent Resilient Framework) in the case of application), and I hope to Campus Network for reference.First briefed the main item -- Nantong a university campus network construction process, expounding on the campus network construction and renovation projects the purpose and significance.Second on the college campus network related concepts, technology, a hardware-based network of the construction phase, information systems mainly to the construction phase and the virtual university construction phase of the proposed Digital Campus concept, structure and construction goals.Then to Nantong a university campus network for the actual construction of the background of the needs of the campus network, construction principles, discussed the specific network platform design example. IRF Technology and Application in the case of lines, campus network routing design, the network's three-tier structure, the IP address planning, VLAN (Virtual Local Area Network) classification, the backbone technology of choice for the detailed planning and design.The article highlights from the campus network protocol design, first introduced computer network routing protocols use of the profile and elaborate OSPF (Open Shortest Path First, the Open Shortest Path First protocol) routing protocol in principle, summed up OSPF routing protocol planning principles, given the Campus Network implementation of the OSPF routing protocol examples.
