What Routing Metric Affects A Path’s Potential Performance Due To Delay?
The latency will affect a path’s potential performance due to delay. Now, let us discuss the routing metrics in detail. We all know that we have several different types of routing protocols. Each of these routing protocols has unique features and characteristics. These routing protocols can be used for many reasons at some point in the network.
All of these routing protocols will use a metric. Here we will talk about the main purpose of the metric and how it is used. And we also learn about the routing protocol metrics among all other routing protocols.
When multiple updates are received to the same route, in order to determine the best route, we use the routing metrics protocol. The routing can see several updates from all the different routers from the same network. The metric is like a numeric value and the difference between each of the routing protocols can be a small value or can be a large value. The routing protocol can look at the metric of all the similar routes and will use the lowest metric in order to determine the best route. Therefore, we can say that the lower the metric is, the best the route can be.
The routing protocol will look into it, if it didn’t have a metric, it would be having all the updates in the same network. But we wouldn’t know which one will be in the use.
When a router receives several paths to find the destination address, and the one which can make into the routing table is known to be the best path. We can use different methods in order to find the best path.
We assign a value to each path, this is called the metric value. In all of the metric values, we only prefer the lowest metric value. Each router can take the information and will make its own best path to reach the destination.
We have distance-vector routers and link-state routers, they will advertise the network and its metric to the other networks. For suppose, when we cannot find the best route path, then we discard it from the routing table and use the next best path. This is the main advantage of dynamic routing. The routing table can update itself if any changes happened in the network.
There are different metrics that are used by the different routing protocols. The first one is Rip. The rip stands for routing information protocol, this will always use the Hop count as the metric value. Certain types of routing protocols can able to analyze the topology in many ways.
The network service providers can maintain several connections to main the network redundancy. In order to make a better decision and in order to get the exact location, to find the best among the multiple routes., we can use algorithms, rip count can be used to calculate the routing metrics. All these different routing protocols can take different things into consideration.
