Question

b, 10 d.12 e is not known yet (roblems 63-68) Ten (10 Megaby of data are transmitted from one computer to another computer on a local tes area network using Ethernet protocol (IEEE 802.3). The protocol converts the data to data frames using the frame structure shown below. Determine the following quantities: (note: One Megabyte 1024 bytes) The Frame Structure of IEEE 802.3 used for this problem Preamble Start Destination Source Data address length 1500 bytes 4 bytes bytes 1 byte 6 bytes 6 bytes 2 bytes Note: 1 MB m (024) bytes 63. The amount of frame overhead is a. 19 bytes lb. 23 bytes c, 1500 bytes e. 1523 bytes d. 1519 bytes 64. The frame efficiency is a. 94.26% b, 95.86% c, 96.10%. d. 97.26% c, 98.49% 65. The number of frames needed for the above data transmission is a, 6667 b, 6812 c, 6991 d, 6872 e, 6554 66, The amount of overall overhead is a, 173,342 bytes b. 111,856 bytes c, 108,999 bytes d 181,766 bytes e, 160,793 bytes

Explanation / Answer

63. The amount of frame overhead is:

e. 1523 bytes (4+1+6+6+2+1500+4=1523)

65. The number of frames needed for the above data transmission is:

c. 6991 (10*1024*1024/1500=6990.5 =6991)

66. The amount of overall overhead is

e. 160,793 bytes(23 bytes*6991 = 160,793 bytes)
