, the router selects routes based on distance, which is also called the distance vector protocol. The router collects all the different paths that can reach the destination, and stores the path information about the minimum number of sites to reach each destination. All other information except the Optimal Path to the destination is discarded. At the same time, the router also uses the RIP Protocol to notify neighboring routers of the route information. In this way, the correct routing informati

in autonomous systems are called "Internal gateways" and the protocols used are called "Internal gateways ". There are two types of internal gateway protocols: distance vector protocol (RIP) and network protocol (OSPF. The difference between the link status routing protocol and the distance vector protocol is that the router that uses the link status routing protocol maintains a network topology instead of switching the distance to the destination. Then, we use the database to represent the gra

an industrial standard in Early 1990s S. It is a typical Link Status Protocol. The main features of OSPF include: support for vlsm (long subnet mask), fast convergence, low bandwidth usage, and so on. The OSPF protocol exchanges link status information between neighbors so that the router can establish a link status database (LSD). Then, the router uses SPF (Shortest Path First, Shortest Path First) based on the information in the database) calculate

At the same time, the router also uses the RIP Protocol to notify neighboring routers of the route information. In this way, the correct routing information gradually spreads to the entire network. RIP is widely used, which is simple, reliable, and easy to configure. However, RIP is only applicable

job first (SJF) is to select one or several jobs with the shortest estimated run time from the fallback queue and transfer them into the memory run. The short process first (SPF) scheduling algorithm chooses a process that estimates the shortest running time from the ready queue, assigns the processor to it, causes it to execute immediately and executes until it is completed, or when an event is blocked to abort the processor and then re-dispatched.C
