These bridges are implemented mainly in Ethernet networks.
So it can also merge several bridges to check incoming traffic in a better way. This estimates the information when a packet is routed to its position. This bridge saves the addresses of MAC within a table that is similar to a routing table. These types of bridges are most popular and operate in a transparent way to the entire networks which are connected to hosts. The other devices within the network are unaware of the existence of bridges. The main function of this bridge is to block or forward the data depending on the MAC address. Transparent BridgeĪs the name suggests, it is an invisible bridge in the computer network. Types of Bridgesīridges in the computer network are classified into three types which include the following. So following transmissions are transmitted to the preferred receiver only.Ī bridge utilizes a database to determine where to transmit otherwise remove the data frame. But, maintains the MAC (media access control) address table to find out new segments. Similar to hubs and repeaters, bridges broadcast data to each node. These network devices work at the data link layer in an OSI model to connect two different networks and provide communication between them. In this way, the bridge reduces traffic in a computer network.Ī bridge in a computer network connects with other bridge networks that utilize a similar protocol. Therefore, the PC2 is accessible in segment1, which means the bridge transmits the data in segment1 only & eliminates all the connected PCs in segment2. So the bridge reads the MAC address & decides whether to transmit the data to segment1 or segment2. For instance, PC1 transmits the data to PC2, where the data will transmit to the bridge first. In a computer network, a bridge separates a LAN into different segments like segment1 & segment2, etc and the MAC address of all the PCs can be stored into the table. The working principle of a bridge is, it blocks or forwards the data depending on the destination MAC address and this address is written into every data frame. The main function of this is to examine the incoming traffic and examine whether to filter it or forward it. In the OSI model, a bridge works at layer-2 namely the data link layer. So that network performance can be improved using a bridge. Every section in the network represents a collision domain that has separate bandwidth. Definition: A bridge in a computer network is one kind of network device, used to separate a network into sections.
