A simple concept of the bridge in networking

A bridge is also called Layer 2 Switch. A network bridge is a device that is primarily used in Local Area Networks (LANs). It is because these networks can potentially flood and clog a large network.

It is one of their abilities that they broadcast data to all the nodes if they do not know the destination node’s address. The bridge uses a database.

The purpose of this database is to ascertain where to pass the data frame, where to transmit the data frame, or where to discard the data frame. Network bridges are also called Ethernet bridges. They connect two segments of a single network together. The main purpose of bridges is to divide a network into different manageable sections.

Following are some Types of bridges in networking

  1. Transparent Bridge:

This is a bridge in which the stations are completely unaware of the experience of the bridge. For example, May or May not a bridge is added or deleted from the network, the station’s reconfiguration is unnecessary. This bridge makes use of two different processes like bridge forwarding and bridge learning.

  1. Source routing bridge:

In this bridge, the routing operation is performed by the source station. The frame specifies which route to follow. The hot discovers the frame by sending a special frame which is called a discovery frame. This spreads through the entire network by using all possible paths to the destination.


What is the bridge in networking?

A bridge is a computer networking device. It is used to provide the interconnection with other bridge networks. The other bridge networks must use the same protocol.

In Open System Interconnection (OSI), the bridge device works at the data link layer. It connects two different networks together. It also provides communication between the two different networks.

A bridge is similar to repeater and hub in a way that they broadcast data to every node. However, the bridge maintains the Media Access Control (MAC) address table as soon as it discovers new segments. Subsequent transmission is sent only to the desired recipient.

Advantages of bridges:

  • Bridges can extend a network.
  • Bridges can act as a repeater.
  • They can reduce network traffic on a segment.
  • They can subdivide the network communication.
  • They increase the available bandwidth to individual nodes.
  • Bridges reduce collisions as well.
  • Bridges can create separate collision domains.
  • They can connect different architectures.

Disadvantages of bridges:

  • They are slower than repeaters.
  • Filtering makes them slower.
  • They do not filter broadcasts.
  • Bridges are more expensive.
  • They must use routable protocols.
  • They need to understand the protocols which they forward.
  • They require a lot of amount for initial configuration.
  • These are complex devices.
  • These devices are unable to read a specific IP address.
  • Its speed is slow.
  • Bridges cannot use a firewall as a device.
  • They send messages to all the nodes.
  • Sending a message to all nodes reduces speed.
  • Sending messages to all nodes causes a waste of time.
