## Shortest Path Routing Algorithm

**Shortest Path Routing** means the progression of discovering the best routing paths to deliver the data packets of an **internal network to a destination with high speed**. To ensure the data packets delivery with the shortest time the ** shortest path routing uses the algorithm**.

**Overview of Flow-based Routing**

In the following description, you will come to know about the flow-based routing method involved in the recent days. They are mentioned below for your understanding.

- The type of flow-based algorithm for routing is used to ensure the quality of the service to match out the data packets from the source host to the destination host
- The flow-based routing technology normally takes the topology of the wireless network, data rate, and the bandwidth capability of the links to facilitate the routing paths in the computer network

We focus the quality of the content as we are serving the college students and scholars on the **project insights relating to the network related projects**.

Next, we can have a look at the overview of the findings of the shortest path in the network,

**How to discover the shortest path in a Network?**

- Generally, we use algorithms to discover the shortest path in a network to route the data
- Dijkstra is a kind of algorithm that can discover the shortest path from the node graph to every single node which is presented in the same data graph structure and they are accessible from the initial node. This is how the shortest path is found in the network by the Dijkstra algorithm.

Furthermore, we can discuss the **utilization of the shortest path routing**. Without a doubt, we are offering the best solutions to your expectations which will match your project ideas with clear ideas. Let us have an idea about the utilization of the shortest path routing.

**When to practice the shortest path routing in a network?**

When the communication of two particular vertices is connected with the weighted graph. Then it is used to discover the **best route to minimize the length between the two nodes**. In short, shortest path routing is used to find the best route to minimize the distance of the transmission of the data packets.

**Best Algorithms for shortest routing path**

Generally, shortest path routing algorithms use the graph model with vertices and edges which will connect them up to find the best routing path. They are mentioned below for your better understanding.

- The graphs have been classified to evaluate the algorithm for the comparison among them. They may be a weighted graph, indirect graph, or direct graph
- Johnson’s Algorithm
- Dijkstra Algorithm
- Final Note Algorithm
- Floyd-Warshall Algorithm
- Bellman –Ford Algorithm

The above-mentioned algorithms are explained below for your understanding. In fact, our **researchers are giving real-time explanations**. The following will help you to understand the best algorithms practices in the shortest path routing.

**Johnson’s Algorithm**

- Johnson’s Algorithm runs with the sparse graphs effectively
- It makes use of the Bellman-ford algorithm and Dijksta’s algorithm to evaluate the shortest path
- Initially, it makes use of the Bellman-ford algorithm to cut out the negative edges
- Eventually, it makes use of Dijksta’s algorithm to compute the shortest path in the real graph

**Dijksta’s Algorithm**

- Dijksta’s algorithm has the benchmark from other algorithms as it is capable of discovering the very shortest path from the nodes which is presented in the same graph
- Without changing the graph’s nature it moderately finds the best path for routing commencing from every single node to another node with every reachable node
- While using this algorithm we are supposed to run the algorithm for once is enough because this algorithm runs out till every nodes visit
- We need not run the algorithm to find the shortest path for routing unless the graph structure changes made
- If it is changed, we need to re-execute the algorithm for the best update on the shortest path for our network projects
- For instance, if we need to go from one place to another place, but they are the areas with congestion, traffics or has some undergoing works, Dijksta’s algorithm will help us to discover the shortest route to reach the estimated destination

**Bellman-Ford Algorithm**

- Bellman-ford algorithm is proficient with the handling of graphs with negative edges
- This algorithm is used to find the shortest paths between each nodes of the graph
- There is a vital thing to be noted here is in which edge has the negative value
- Additionally, note the cheapest or shortest path
- This algorithm terminates the negative cycles due to the capability of discovery of the correct route

**Final Note Algorithm**

- According to the problem’s weightage, we need to turn to the algorithms listed out
- Actually, it is hooked based on type of the graphs that we are using to find the shortest path
- For instance, the negative weight edges will be sorted out by the Bell-man Ford Algorithm
- At the same time, the graphs which have no negative edges will be sorted out by the Dijksta’s algorithm
- Every algorithm has its own capabilities and they own many features and they may differ from each
- We need to pick the algorithm according to the type of graph that we are using for operational services

**Floyd-Warshall Algorithm**

- Floyd-Warshall algorithm computes every combination of node pairs rather than evaluating each sing node in accordance with the shortest distance between the nodes
- It breaks out the large issues into lesser ones then it collates them to solve the root cause for the shortest path issue
- Generally, Floyd-Warshall algorithm evaluates every possible route for the nodes and it will create the routes for the multi-stop trips so that it was considered the useful algorithm
- Routes planning software like Google map is adapted this algorithm to provide the best and fast routes from any given locations
- In the event of this nature, the Floyd-Warshall algorithm will help you to reach the destination with the fastest way

**Common Procedures to discover the shortest path**
