Introduction

In the realm of computer networking, routing protocols play a pivotal role in facilitating efficient and reliable data transmission across interconnected networks. A routing protocol is a set of rules and algorithms that determine how data packets are transmitted from a source to a destination. It enables the creation and maintenance of routing tables, which contain information about network topology, paths and metrics. This article explores the fundamental concepts and types of routing protocols, their significance in modern networks and their contributions to enhancing network efficiency and connectivity. Routing protocols can be broadly classified into two categories: Interior Gateway Protocols (IGPs) and Exterior Gateway Protocols (EGPs) [1].

Description

In the healthcare sector, motion sensors play a vital role in monitoring patients and providing healthcare professionals with IGPs are used to facilitate routing within an Autonomous System (AS), which refers to a network controlled by a single administrative authority. The most widely used IGPs include Routing Information Protocol (RIP), Open Shortest Path First (OSPF) and Intermediate System to Intermediate System (IS-IS). RIP, a distance-vector protocol, calculates the shortest path based on the number of hops. OSPF, a link-state protocol, utilizes a more complex algorithm, considering factors such as link speed and network congestion. IS-IS is also a link-state protocol, primarily used in large-scale service provider networks.

EGPs, as the name suggests, are responsible for exchanging routing information between autonomous systems. Border Gateway Protocol (BGP) is the primary EGP used on the Internet. BGP allows network administrators to determine the best path for data transmission across multiple, considering various factors such as policy-based routing and network preferences. Routing protocols operate through a series of steps, including neighbor discovery, route exchange, route selection and route update. Routing protocols establish and maintain relationships with neighboring routers to exchange routing information. This process involves sending and receiving "hello" packets to discover adjacent routers and form adjacencies or neighbor relationships [2,3].

Once adjacencies are established, routers exchange routing information, typically in the form of routing updates or advertisements. These updates contain details about network topology, metrics and reachability information. The frequency and mechanism of route exchanges vary depending on the routing protocol. Routing protocols employ various metrics and algorithms to determine the best path or route to a destination. Metrics can include factors like link cost, bandwidth, delay and reliability. The route selection process involves evaluating these metrics and selecting the optimal route based on predefined criteria. Routing protocols continuously monitor network conditions and respond to changes in topology or link status. When a link failure or network change occurs, routers exchange route updates to reflect the new network state. This ensures that routers have up-to-date information to make accurate routing decisions. Routing protocols offer several benefits that contribute to enhanced network efficiency and connectivity. By dynamically exchanging routing information and selecting the best available path, routing protocols enable efficient data transmission. This minimizes delays and ensures that traffic is routed through the most suitable network resources [4,5].

Conclusion

Routing protocols support fault tolerance by automatically rerouting traffic in case of link failures or network congestion. They provide redundancy and alternative paths, improving network reliability and minimizing downtime. With the ability to handle large networks and complex topologies, routing protocols scale effectively as networks grow. They adapt to changes in network size, allowing for seamless expansion and accommodating additional devices and connections.
