Brouter In Computer Network : Function, Types and Working

computer networks use many networking devices such as routers, switches, and hubs are crucial for communication between devices. However, there is another device, less known but highly important, called a brouter. The term “Brouter” is a combination of bridge and Router, and this hybrid device plays a vital role in network communication. In This article we will learn What is brouter in computer network, function, and applications of brouter in computer network, explaining its features, types, advantages, disadvantages, and its comparison with other networking devices.

What is a brouter in computer network

A brouter, short for bridge and router, is a Networking device that combines the functions of a bridge and a router. It is designed to route data packets between different networks for routable protocols, such as IP (Internet Protocol), while it also acts as a bridge to forward packets within the same network for non-routable protocols. This dual functionality makes the brouter particularly useful in hybrid network environments where both modern and legacy systems coexist. By handling both routing and bridging functions, the brouter ensures efficient communication across different devices and protocols, simplifying network management and enhancing connectivity.

How Does a Brouter Work?

The brouter works by deciding how to handle data packets depending on what protocol they use. If the packet belongs to a routable protocol such as IP (Internet Protocol), the brouter acts as a router and forwards the packet to another network. If the packet uses a non-routable protocol, the brouter acts as a bridge, sending the packet within the same network. It analyzes each packet to decide whether to route or bridge it, allowing the brouter to efficiently manage both modern and legacy protocols. This makes it a versatile device for hybrid networks.

Features of a Brouter

Dual Functionality: A brouter combines the functions of a bridge and a router, enabling it to route data packets between different networks and bridge packets within the same network.

Protocol Handling: It supports both routable protocols (like IP) and non-routable protocols, making it useful in diverse networking environments.

Network Segmentation: Brouters help segment large networks into smaller, manageable sections, reducing congestion and improving performance.

Hybrid Network Support: Ideal for hybrid networks, brouters enable communication between modern and legacy systems using different protocols.

Connectivity Across Network Types: A brouter can connect different types of networks, such as Ethernet and token ring, ensuring seamless communication.

Simplified Network Setup: By combining two functions in one device, brouters reduce the need for separate hardware, simplifying network design and management.

Types Of Brouter In Networking

Brouters, as hybrid devices combining the functionalities of both bridges and routers, can be classified into different types based on their features, operation, and the specific needs of the network. The primary types of brouters include.

Hardware Brouter: A physical device that combines the features of a bridge and a router in a single unit. It is specifically designed to perform both routing and bridging tasks. Commonly used in larger networks where dedicated hardware is required for efficient performance.

Software Brouter: A software brouter is a program installed on a computer or server that performs the functions of a brouter. It handles both routing and bridging tasks through software-based configurations. Software brouters are more cost-effective and suitable for smaller networks or environments where physical devices are not necessary. They are flexible and can be updated or customized as needed.

Advantages of Using a Brouter

Dual Functionality: A brouter combines the features of both a router and a bridge, allowing it to manage both routable and non-routable protocols.

Cost-Effective: Since it performs the tasks of both a bridge and a router, using a brouter can save money by eliminating the need for two separate devices.

Improved Network Performance: By efficiently routing and bridging data, a brouter can help manage network traffic better, reducing congestion and improving overall performance.

Supports Hybrid Networks: Brouters are ideal for networks that use a mix of modern and older systems. They allow seamless communication between devices using different protocols.

Better Network Segmentation: Brouters help divide large networks into smaller, manageable segments, making it easier to control network traffic and enhance security.

Disadvantages of Using a Brouter

Complex Configuration: Setting up a brouter can be more complex than configuring a standalone router or bridge.

Limited Scalability: While a brouter works well for smaller to medium-sized networks, it may not be as effective in large-scale networks.

Higher Cost for Some Networks: While a brouter can save money by combining two devices, in some cases, it might still be more expensive than using separate routers and bridges, especially for smaller networks that don’t need its full functionality.

Limited Protocol Support: A brouter may not support all types of protocols as efficiently as dedicated routers or bridges. This can be a limitation if the network relies on specialized protocols that the brouter cannot handle effectively.

Conclusion

A brouter is a versatile networking device that combines the functions of a bridge and a router. It is particularly useful in hybrid networks where both routable and non-routable protocols are used. Although its relevance in modern networking has diminished, it remains a valuable tool for managing legacy systems and transitional environments. Understanding brouters and their functionality can help network administrators design efficient and cost-effective network solutions, especially in scenarios that involve diverse protocols and devices.
