Problems solved by technology
[0004] Usually, in the network platform, the forwarding of data frames and the change of routing information are automatically processed by the operating system, and experimental students cannot intervene in it, nor can they see the processing process, let alone try to design their own protocols and algorithms
Therefore, it restricts the depth of students' understanding of computer networks and limits students' innovative ability

Embodiment Construction
[0033] The present invention will be further described below in conjunction with specific embodiments.
[0034] The present invention specifically relates to an experimental programmable routing platform and its implementation method, which are used in teaching experiments of computer network courses, so that students can design protocols and routing algorithms by themselves and observe the routing process, thereby deepening their understanding of the working principles of computer networks. understand.
[0035] attached figure 1 It is a schematic diagram of the structural composition of the programmable routing platform. The platform includes more than two single-network card hosts 1 and one multi-network card host 2. The number of network adapters of the multi-network card host 2 is greater than or equal to the single-network card host 1. The network adapter of the host 1 and the network adapter of the multi-network card host 2 are connected through a network communication ...

The invention discloses an experimental programmable routing platform and its realization method, which belongs to the technical field of computer network teaching, adopts a low-cost multi-network card host as a router, and uses the operating system's own security strategy to block the connection between the network card and the operating system , prevent the operating system from automatically processing the data frame, and use sharpcap to capture and send the data frame at the same time to realize the processing of the network data frame. Students fully demonstrate the transmission process of data frames, thereby enhancing students' interest in learning and understanding of computer networks.
Description
technical field [0001] The invention belongs to the technical field of computer network teaching, and specifically relates to a teaching experiment programmable routing platform for computer network courses and its implementation method Background technique [0002] The network experiment platform generally uses the transmission, capture and analysis of network data frames to show students the process of computer network processing data frames and reveal the working principle of computer networks. [0003] The LAN generally uses a broadcast channel, and the entire network can be easily accessed from one site. The connection between the computer and the external LAN is through a network adapter (Adapter), and the communication between the adapter and the LAN is carried out in a serial transmission mode through a cable or twisted pair. The so-called broadcast communication means that when a computer sends data, all computers on the bus can detect this data. In order to reali...
