The state of directly connected links
I think the answer is the state of each directly connecyed link.
Distance vector protocols exchange their routing tables, and add a metric to each route. Link-state routing protols exchange topology information, then calculate the routes. As a result, there are the following fundamental differences:The information that is exchanged - routing table vs. topology information.Link-state protocols know the topology of the network (or an area); distance vector routing protocols don't.When the best route is calculated: in distance-vector routing protocols, a metric is added while the route is propagated from router to router. In link-state protocols, the best route is calculated separately by each router, only after having complete topology information.
Routing Information Protocol (RIP) and Interior Gateway Routing Protocol (IGRP) are two very popular Distance Vector routing protocols
Distance vector protocols compute their routing tables before sending routing updates; link-state protocols do not.
Distance Vector protocols use the Bellmanâ??Ford algorithm. The ARPANET system relied on Distance Vector protocols as their main routing technique in the early 80s.

Distance-vector algorithms refer to routing protocols - protocols used by routers to inform each other about available routes. In distance-vector algorithms, such as RIP or EIGRP, the routers inform each other about their routing tables, and each router adds a metric (or distance) to the route - however, the routers don't know about the topology of the network (unlike the link-state protocols, such as OSPF).
metric, network mask, neighbor router ID, administrative distance
# Adequate safety protocols # Training and periodic retraining in the protocols # Insulation # Distance # Turning the power off before servicing
Primarily distance, but also the protocols and network medium.
