Question

You have been hired to upgrade a network of 50 computers currently connected to 10 Mbps hubs. This long-overdue upgrade is necessary because of poor network response time caused by a lot of collisions occurring during long file transfers between clients and servers. How do you recommend upgrading this network? What interconnecting devices will you use, and what benefit will you get from using these devices? Write a memo describing the upgrade and, if possible, include a drawing of the new network.

Explanation / Answer

I have been recently hired to upgrade a company’s current network. Currently this company has a 10BaseT network established (Regan, 2004). This client is stating that they need to increase the overall bandwidth to the network and is having collisions issues occurring within the network which is causing more latency within the network. My two primary recommendations to upgrade this network are to; first go from a 10BaseT network to a 100BaseTX network, and second replace any hub currently in use with a switch capable of 100BaseTX data transfer standards. Transferring from a 10BaseT to a 100BaseTX network will require the additional purchase of networking devices but will increase the overall bandwidth from 10 Mbps to 100 Mbps for each user in the network (Regan, Local area networks, 2004). By replacing the outdated hubs currently in use with switch will create a more specific collision domain (Regan, Local area networks, 2004) that if found when hubs are in use. With the use of hubs all the ports on the hub are part on a collision domain, so each computer connected on the hub can be effected by collision of data as it passes through the hub. When switches are use each port on the switch is its own collision domain and collision rarely occur. This upgraded network will allow to create a more specific collision domain (Regan, Local area networks, 2004) that if found when hubs are in use. With the use of hubs all the ports on the hub are part on a collision domain, so each computer connected on the hub can be effected by collision of data as it passes through the hub.
