10 Questions
Match the packet fragmentation strategies with their descriptions:
Transparent fragmentation = The fragments are not reassembled until the final destination. Nontransparent fragmentation = The fragments are reassembled in the receiver router.
Match the packet header fields with their uses:
Packet number = To determine the order of the fragments. Fragment offset = To determine the position of the data. End-of-packet flag = To indicate the end of the packet. Packet size = To determine the size of the packet.
Match the disadvantages of the fragmentation strategies with their descriptions:
Transparent fragmentation = The overhead can be higher than with nontransparent fragmentation. Nontransparent fragmentation = The packet is needed to be repeatedly fragmented and reassembled.
Match the packet sizes with their descriptions:
Maximum packet size of 8 payload bytes plus header = The size of the packet after passing through a network. Size 5 gateway = The size of the packet after passing through a gateway. Elementary data size of 1 byte = The size of the original data bytes. 10 data bytes = The size of the original packet.
Match the packet fragmentation scenarios with their descriptions:
Figure 5-42(a) = Transparent fragmentation. Figure 5-42(b) = Nontransparent fragmentation. Figure 5-43(a) = The original packet. Figure 5-43(c) = The fragments after passing through a size 5 gateway.
Match the packet fields with their uses:
Packet number = To determine the order of the packets. Fragment offset = To determine the position of the fragments. End-of-packet flag = To indicate the end of the fragments. Packet size = To determine the size of the fragments.
Match the packet fragmentation strategies with their advantages:
Transparent fragmentation = The packet is not needed to be repeatedly fragmented and reassembled. Nontransparent fragmentation = The overhead can be lower than with transparent fragmentation.
Match the packet sizes with their scenarios:
Maximum packet size of 8 payload bytes plus header = The packet size after passing through a network. Size 5 gateway = The packet size after passing through a gateway. Elementary data size of 1 byte = The packet size of the original data. 10 data bytes = The packet size of the original packet.
Match the packet fragmentation scenarios with their figures:
Transparent fragmentation = Figure 5-42(a) Nontransparent fragmentation = Figure 5-42(b) Original packet = Figure 5-43(a) Fragments after passing through a size 5 gateway = Figure 5-43(c)
Match the packet header fields with their descriptions:
Packet number = A unique identifier for the packet. Fragment offset = The position of the fragment in the original packet. End-of-packet flag = A flag indicating the end of the packet. Packet size = The total size of the packet.
