What is a Network Bridge : A device that can separate a local area network (LAN) into multiple small segments is known as a network bridge. It works under the data link layer of the OSI model and stores the mac address of a PC available in a network. In reducing traffic, bridges are very useful. Generally, if we see the bridges, the bridges connect two areas like that. This network bridge connects two different LANs.
What is a Network Bridge?
To prevent collisions, this network bridge is very useful because it reduces traffic by dividing the channels. In improvement of network performance, also a bridge is used because when the network connections are divided into sections, all the sections have a separate bandwidth.
Different types of network bridges
- Transparent Bridges
On the MAC address, blocking or forwarding of the data is the main function of transparent bridges. According to its name, it is totally transparent, or we can also say invisible, because it works totally transparently. It is used in Ethernet networks. Transparent bridges are most common and popular too.
- Translate Bridges
When we have to change one type of network system into another system, then these bridges are used. According to the direction of transmission, the bridge can add or remove data from the network. A bridge that can translate between various protocols of a network is known as a translator bridge.
- Source Routing Bridges
The route between two hosts is determined by the source routing bridge. This technique is used for token ring networks, which are designed by international business machines (IBM). Source routing bridges made defined decisions regarding structure forwarding in the network system.
The network bridge uses it as follows
A bridge in a computer network is a technique that is used in connecting with another network having the same protocol. In managing collisions, also a network bridge is used, as it filters or reduces the traffic in the network system. In an OSI model for connecting various networks, which helps them to communicate with each other, this type of network device is used at the data link layer. Bridges connect two areas and transfer information from one place to another like other techniques, i.e., hubs, repeaters, etc.
Conclusion
Like a normal bridge, a network bridge also connects two networks, by which the traffic doesn’t happen. Network bridges are classified into several types, such as transparent bridges, translator bridges, and source routing bridges. Mainly bridges work upon two models: local and remote. It filters the traffic; that’s why collisions don’t occur in network systems.
FAQs
Why do we need a network bridge?
We need a network bridge because it helps us in many ways, like by the use of this bridge, there is no collision happening as it reduces the traffic by dividing it into multiple ways.
What is the IP address of bridges?
The bridges do not have an IP address; in fact, they are assigned physical addresses.
How many types of bridges are there?
There are 3 types of bridges. 1. transparent bridges; 2. translate bridges and source routing bridges.
What do you mean by a network bridge?
A computer technique that is used to separate the LANs into the numbers of individual sets, which helps other networks to communicate with each other.
