Collision Domain
The segmentation of a computer network can be done both logically and physically. A collision domain is an example of the logical network segments in which packets of data can collide with each other. And the Ethernet protocol is one of the most common protocols utilized in referring to a collision domain. Decreasing the size of a collision domain can thus be by achieved that setting up network devices (normally switches/network bridges) that utilize microsegmentation. Contrary to network hubs and regular repeaters that normally transmit each sole packet, LAN switches have the ability to filter and forward packets through their Media Access Control (MAC) address (Palmer 30). Basically, the switch reads the forty-eight bit MAC address from the network card and filters or stops frames inside the LAN or a particular network domain. It is also important to note that a switch or network bridge works to advance frames that have addresses and that are not found in its domain and will copy and transmit frames to the gadgets found within its network.
A router also has the ability to sort out, forward, or drop packets on the basis of MAC addresses as well as act on the basis of the Internet Protocol (IP). As such, routers have the ability of reducing the collision domain by transmitting only addresses that contain addresses on that particular network to the LAN (Palmer 31). These network gadgets have the ability to route or redirect packets by the IP or MAC addresses as well as by the type of data (plain text, email, graphics), function or port utilized (HTTP, POP3, FTP), and other functions (acting like a firewall) and other variables so as to enhance the performance and decrease the collision numbers and regulate users.
