Question

What are the benefits of building redundancy into a network? What are the potential issues with building redundancy?

Answer 1

Network redundancy can be defined as the process of adding the network device, along with a line of communication to provide network availability. Benefits of building redundancy into a network: It decreases the risk of network failure. If one server fails to transfer the information, then the backup server will take the charge to help in continuing the communication. Potential issues with building redundancy: Denial of service and cyber attacks are the threats to network. Without the use of backup system the one point failure can disrupt the entire system.

Answer 2

The benefits of building redundancy into a network is the provision of an alternative path for data transmission in the event of a failure of the primary route of data transmission, thereby ensuring the availability of the network and reducing the likelihood of a network failure during the data transmission

Potential issues with building redundancy includes

1) When the broadcast frame generated by a device in a network that has redundancy is forwarded by another device within the network that has no loop avoidance algorithm or schematics, the network switches will keep broadcasting the same data repeatedly such that the network bandwidth is consumed and potentially leading to a shut down of the network

2) More than one copy of a frame may be received by a device in the network with redundancy

3) Instability of the MAC address table, when the switch makes entry into the MAC table for a frame generated from a particular source but however received from more than one link
