4. Please briefly describe the advantages and disadvantages of flood routing protocol?

The advantages and disadvantages of Red Sail Routing Protocol are as follows:

1, flooding routing protocol can effectively improve the transmission efficiency of the network, reduce the occurrence of network failures, and provide faster and more reliable routing services. It provides a good foundation for network optimization and management.

2. It can also improve the reliability of the network and ensure that data packets can be safely transmitted to the destination. In addition, flooding routing protocol can make more effective use of network resources, help network administrators reduce network congestion and achieve the best network performance.

3. Flooding routing protocol is a new routing protocol based on the propagation of routing packets in the network, which can improve the transmission efficiency of the network, reduce the occurrence of network failures and provide faster and more reliable routing services. It contributes to the effective management of the network, makes the performance of the network optimal, and lays a solid foundation for the development of the network.

Expand knowledge:

Distance vector routing algorithm is a distance-based routing algorithm, which determines the shortest path by calculating the distance from each node to other nodes. Each node maintains a distance vector, which contains distance information to other nodes. Nodes update routing tables by exchanging distance vectors. The advantage of distance vector routing algorithm is simple and easy to implement, but there are some problems such as high computational complexity and slow convergence.

Link state routing algorithm is a routing algorithm based on link state. By collecting the link state information of all nodes in the network, the shortest path from each node to other nodes is calculated. Each node maintains a link state database, which contains the link state information of all nodes in the network.

Nodes update routing tables by exchanging link state information. Link state routing algorithm has the advantages of low computational complexity and fast convergence, but it has the problem of high maintenance and exchange cost of link state information.

Path vector routing algorithm is a path-based routing algorithm, which determines the shortest path by maintaining the path information from each node to the destination node. Each node maintains a path vector, which contains the path information to the destination node. Routing tables are updated by exchanging path vectors between nodes.

Path vector routing algorithm has the advantages of low computational complexity and fast convergence, but there is a problem that the routing loop and routing information are inconsistent.
