What is the basis of the calculation in network measurements, according to distance vector routing?
What is the basis of the calculation in network measurements, according to distance vector routing?
- Hop count and link delay
- Router's idle time and packet size
- Network congestion and packet loss
- Bandwidth, delay, and link queue lengths (correct)
How do adjacent routers exchange information in distance vector routing?
How do adjacent routers exchange information in distance vector routing?
- Using a hierarchical routing system
- By broadcasting to all routers
- Through centralized servers
- By exchanging distance vector tables (correct)
What happens when a router receives vectors from its neighboring routers in distance vector routing?
What happens when a router receives vectors from its neighboring routers in distance vector routing?
- It waits for a convergence period
- It updates its routing table immediately
- It ignores the information and uses its current routes
- It adds the delay to the neighbor in each case and chooses the best route (correct)
