routing
An advantage of centralized routing is: routing does reflect changing network conditions, such as computers that are overloaded by many messages if anything happens to the computer developing the routing table, the routing tables cannot be changed until that computer is fixed, or until a new computer is selected to perform the function routing decisions are simple the routing tables are stored at all computers in the network it requires more processing by each computer or router in the network than dynamic routing
routing decisions are simple
