Problems solved by technology

[0014] In the current research, there are still some unresolved problems in network routing: 1) Due to topology changes and link delays, existing routing protocols for the Internet and ad hoc networks cannot meet the routing requirements of an integrated heterogeneous fusion network

2) Existing routing schemes are mainly applicable to specific network scenarios and cannot be applied to different types of networks in a general way

3) In the routing process, existing schemes rely too much on certain trusted nodes

Easy single point of failure due to single point of vulnerability of "trusted" nodes

4) Most existing work cannot be directly applied to integrated heterogeneous fusion networks

5) Most of the existing routing schemes do not consider the authenticity and credibility of the topology information provided by different networks, and are vulnerable to various routing attacks

[0016] Problem 1: Solve the trusted problem of cross-domain routing in heterogeneous converged networks

[0017] Problem 2: On the basis of problem 1, solve the problem of automatic cross-domain routing of heterogeneous converged networks: the existing routing schemes are mainly applicable to specific network scenarios, and cannot be applied to different types of networks in a general way, so the existing The solution cannot be directly applied to an integrated heterogeneous converged network

Moreover, due to dynamic topology changes and link delays, existing routing protocols for the Internet and ad hoc networks cannot meet the routing requirements of integrated heterogeneous converged networks

[0018] Question 3: On the basis of Question 1, solve the authenticity and routing reliability of routing topology information: For the open and heterogeneous characteristics of the integrated heterogeneous fusion network, the routing process is more vulnerable to routing information theft, tampering, forgery, and re-routing. Attacks such as release and denial of service can easily lead to serious degradation of network performance or even paralysis of the entire network

[0020] (1) Due to topology changes and link delays, the existing routing protocols of the Internet and ad hoc networks cannot meet the routing requirements of integrated heterogeneous converged networks

[0021] (2) Existing routing schemes are mainly applicable to specific network scenarios and cannot be applied to different types of networks in a general way

[0022] (3) In the routing process, existing schemes rely too much on certain trusted nodes, which are prone to single-point failure due to the single-point vulnerability of "trusted" nodes, and most of the existing work cannot be directly applied to the integration In a heterogeneous fusion network

[0023] (4) Most of the existing routing schemes do not consider the authenticity and credibility of the topology information provided by different networks, and are vulnerable to various routing attacks

[0026] 2. The topology information of the network changes dynamically, and operators may provide false routing information during cross-domain routing, which makes it difficult to ensure the authenticity of topology information and the reliability of routing
