What is the transmission efficiency of a 1,000-byte file sent in response to a Web request HTTP, TCP/IP, and Ethernet? Assume that the HTTP packet has 100 bytes in addition to the 1,000-byte file. Hint: that efficiency = user data/total transmission size. Calculate a single transmission efficiency number from the perspective of the 1,000-Byte file. Use the following assumptions: - 1,000 Bytes for size of user data file - 100 Bytes for size of HTTP header - "Typical" size for TCP header (including the options field) - Default size for IPV4 header (including the options field) - For the Ethernet overhead, assume that "Ethernet 802.3ac" is used. Use the figure below to figure out the size of Ethernet 802.3ac overhead Bytes. Assume that VLAN is used.
