Description
Technical Field
The invention relates to the technical field of computer networks and communication, in particular to a transmission path visual representation method of a software-defined anonymous communication network.
Background
An anonymous communication network is a network capable of hiding a communication relationship of a user, and there are Tor, I2P, and the like as a common anonymous communication network. In an anonymous communication network, data transmission is carried out among nodes according to a preset transmission path, and in order to prevent the data transmission process from being traced and traced, routing calculation is required to be carried out according to a specific network topology in the anonymous network. For example: in the Tor network, an onion routing technology is adopted, a data sender calculates a transmission path of data in advance and encrypts the data hop by hop, the encrypted transmission path is sent along with a data body, the transmission path is partially decrypted by the node every time the data passes through one hop of node, the address of the next hop of node is obtained, and then the data is forwarded to the next hop. The anonymous network based on the onion routing requires a data sending party to plan the whole data transmission path in advance, and nodes in the data transmission path are possibly exposed after the data sending party is out of control, so that some new network technologies are introduced into the construction of the anonymous communication network, the software defined network technology calculates data forwarding paths for all the nodes by a special control center and sends the data forwarding paths to all the nodes in a flow table mode, the data sending party does not need to sense network topology and forwarding nodes, and each forwarding node only needs to know the forwarding node of the next hop in the data forwarding process, and does not need to know the complete transmission path, so that the security is higher. The invention provides a visual transmission path representation method for a software defined anonymous communication network.
In the software-defined anonymous communication network, a network manager needs to know the use conditions of all transmission paths in the network and the network nodes passed by each path in real time, so that the topology of the network needs to be visually displayed. The anonymous communication network is different from the traditional physical communication network, the traditional physical communication network establishes a network topological relation based on physical links, the anonymous communication network is an overlay network, and the communication relation between nodes is not limited by the physical links and can be defined at will, so that the topology of the anonymous communication network has no fixed form and can be changed at any time. In an anonymous communication network system, a network administrator sometimes needs to distinguish nodes by region, and also needs to know operators used by different nodes, and the like. Therefore, it is desirable to design a flexible, efficient and intuitive visual representation method.
A general method for visualizing the network topology is to visualize the network topology according to the relative positions of the nodes and the straight lines of point-to-point connection, as shown in fig. 1 and 2. The visualization method can effectively express the logic relation of the original network topology under the condition of less nodes and connecting lines. However, as the number of network nodes and links increases, drawing a network topology map on a two-dimensional plane causes problems, such as ambiguity caused by the links passing through a certain node, and grouping representation problems of large-scale nodes, such as fig. 3 and 4. Therefore, how to effectively visualize the network topology under the condition of large network scale becomes a problem to be solved.
Therefore, there is a need to provide a transmission path visualization method for a software-defined anonymous communication network to solve the above technical problems.
