4.3-2c. Network Address Translation (c). Consider the following scenario in which host 10.0.0.1 is communicating with an external web server at IP address 128.119.40.186.

A. Class C network address of 210.10.11.0/24 with no subnetting. Design two subnets for the above network A and network B using classful subnetting. Network A has requirement of 60 computers and Network B has requirement of 30 computers. Network-A connected to router interface G0/0 and network-B connected to router G0/1 interface. Show the steps of calculation. B. classless subnetting.
Question 3 Consider a satellite channel running TCP/IP as shown in the figure below. Due to the long round trip time (RTT) and high bit error rate (BER) the conventional TCP congestion mechanism doesn’t work well in a satellite transmission system. 3.1 Assume traditional TCP/IP is used and that the congestion window of the TCP sender is 10k bytes, and it is in congestion avoidance (CA) state with the threshold variable equal to 8k bytes. Now, the sender receives 3 duplicated acknowledgements (ACKs). As a result, explain the effect on the congestion window size and the threshold.
4.02. Subnet addressing. Consider the three subnets below, each in the larger 128.119.160/24 network. The following questions are concerned with subnet addressing. Answer each question by selecting a matching answer. Each answer can be used to answer only one question. [Note: You can find more examples of problems similar to this here.] : A 128.119.160/24 48 hosts 21 hosts 50 hosts C A. V What is the maximum number of hosts possible in the larger 128.119.160/24 network? A. 256 B. 2**32 E. v How many bits are needed to be able to address all of the host in subnet C 64 A? D. 6 C. v Suppose that subnet A has a CIDRized subnet address range of 128.119.160.128/26 (hint: 128 is 1000 0000 in binary); Subnet B has an E. 96 CIDRied subnet address range of 128.119.160.64/26. We now want a valid CIDRized IP subnet address range for subnet C of the form 128.119/160.x/26. What is a valid value of x? F. 0
Qi draw the network if you have the following requirement:- 1. A LAN with the network address 220.3.6.0 (class C). 2. A LAN with the network address 134.18.0.0 (class B). 3. A switched WAN (class C), such as Frame Relay or ATM, that can be connected to many routers. We have shown three. One router connects the WAN to the left LAN, one connects the WAN to the right LAN, and one connects the WAN to the rest of the internet.

6.3-2. Multiple Access protocols (b). Consider the figure below, which shows the arrival of 6 messages for transmission at different multiple access wireless nodes at times t = 0.3, 1.7, 1.8, 2.5, 4.2, 4.6. Each transmission requires exactly one time unit. t=0.0 U 3 U चं n 50 U t=1.0 60 23 t=2.0 For the slotted ALOHA protocol, indicate which packets are successfully transmitted. You can assume that if a packet experiences a collision, a node will not attempt a retransmission of that packet until sometime after t=5. t=3.0 5 t=4.0 6 t=5.0
match IP Src = 10.3.*.* IP Dst = 10.2.*.* match ingress port = 1 IP Src = 10.3.*.* IP Dst = 10.2.*.* action forward(3) 5 Figure 1: Traffic Engineering with Open Flow Figure 1 reveals a network where the traffic flowing from the first host which is attached to router u to the server which is attached to router z needs to be routed along the path u,v,w,z while the traffic flowing from the second host attached to router x router to the server which is attached to router z needs to be routed along the path x,w,y,z. Please describe the local flow table of each of the switches u,v,x,w,y,z (in terms of match and action rules) to enable the routing of the two traffic flows according to the constraints described above. The following IP addresses will be used for the two hosts and the server. • The first host belongs to the subnetwork 10.1.0.0/16. It is attached to router U and has an IP address of 10.1.0.1 OpenFlow Example: datagrams from hosts h5 and h6 should be sent to h3 or h4, via s1 and…
6.3B-5. Multiple Access protocols (5). Consider the figure below, which shows the arrival of 6 messages for transmission at different multiple access wireless nodes at times t=0.1, 0.8, 1.35, 2.6, 3.9, 4.2. Each transmission requires exactly one time unit. t=0.0 n [ 2 3 t=1.0 4 t=2.0 4 For the CSMA/CD protocol (with collision detection), indicate which packets are successfully transmitted. You should assume that it takes .2 time units for a signal to propagate from one node to each of the other nodes. You can assume that if a packet experiences a collision or senses the channel busy and that that node will not attempt a retransmission of that packet until sometime after t=5. If a node senses a collision, it stops transmitting immediately (although it will still take .2 time units for the last transmitted bit to propagate to all other nodes). Hint: consider propagation times carefully here. Hint: consider propagation times carefully here. t=3.0 5 6 t=4.0 t=5.0
Consider the network address 199.200.30.0. We want at least two subnets and between 60 and 70 hosts per subnet. What subnet mask should we use? What would the numbers of the first 2 and last 2 subnets be, along with their address range and their broadcast? Explain your answer.
