Question

Worldwide Charity Worldwide Charity is a charitable organization whose mission is to improve education levels in developing countries. In each country where it is involved, the organization has a small headquarters and usually 5 to 10 offices in outlying towns. Staff members communicate with one another via email on older computers donated to the organization. Because Internet service is not reliable in many of the towns in these countries, the staff members usually phone headquarters and use a very simple Linux email system that uses a server-based network architecture. They also upload and down- load files. What range of frame sizes is likely to be used?

Explanation / Answer

The original Ethernet IEEE 802.3 standard defined the minimum Ethernet frame size as 64 bytes and the maximum as 1518 bytes. The maximum was later increased to 1522 bytes to allow for VLAN tagging.

So, now in our case, since Internet connectivity is not very reliable, so we need to maintain proper frame size as minimal as possible so that there is no loss in data packets while transmission is going on. Hence, the Frame size can be about 64 bytes upto 200 bytes so that we can ensure smaller frames can be send over such unreliable networks and reduce any data loss. If we send huge Data Frames like 1500 bytes, then in such case data loss will also be very huge as network is unreliable. Hence, best option is to send small Frame sizes of 64 - 200 bytes over unreliable networks.

Please let me know in case of any clarifications required. Thanks!
