Prоblem 1 (2 pоints) Creаte а three-tier Fаttree tоpology connecting the 16 hosts (A)--(P) below. Problem 2 (2 points) A random topology such as Jellyfish may provide higher network throughput than a structured topology such as Fattree connecting the same number of hosts using identical switches. Why or why not? Problem 3 (4 points) Consider the network topology show below. Assume CONGA load balancing. Recall CONGA uses a global load (congestion) estimation for path selection. The initial congestion table at time (t=0) for ToR (L0) is shown below. Assume every time a packet is sent out on a given port (i) destined to ToR (L), the congestion value of the entry in the table is increased by 1. Further recall CONGA does load balancing at the granularity of flowlets. Recall the parameter (delta), which estimates the maximum delay difference between two network paths, used to identify new flowlets. Suppose we have packets from flow (F (H1rightarrow H6)) arriving at the ToR (L0) and going upstream. Table below shows the arrival time of each packet. Fill the table with the upstream output port on which each packet will be sent out by CONGA for two different (delta) values. Problem 4 (4 points) Assume DCTCP congestion control. Recall the cwnd update in DCTCP, where DCTCP does additive increase on lack of congestion and multiplicative decrease based on the extent of congestion as dictated by the parameter (alpha). You can assume (g=1) while calculating (alpha). For simplicity, assume DCTCP sends packets in rounds. In each round, DCTCP sends cwnd number of packets, waits for all the ACKs to arrive, and updates the values of (alpha) and cwnd. Then the next round follows with the updated cwnd value from the previous round. Based on this, fill the table below with the cwnd value at the start of each round and (alpha) value at the end of each round. Problem 5 (2 points) Describe the key limitation of sender-driven congestion control protocols such as DCTCP that is solved by receiver-driven protocols such as NDP. Also explain why a receiver-driven protocol is better suited to overcome this limitation. Problem 6 (2 points) Consider a Software-defined Network (SDN) such as Ethane. Suppose a host (H1) sends a packet to host (H2). You may assume that this is the very first packet sent from (H1) to (H2). The packet was received at (H2) after a delay of (t_1) time units. After a while, (H1) sends another packet to (H2) over the same network, and this time the packet was received at (H2) after a delay of (t_2) time units. It was observed that the delay (t_1) was significantly higher than (t_2). Assuming that both packets took the same path, the network does not process any other packet (i.e., the network is completely unloaded with no queuing or congestion) and no failures or changes to network topology happen, provide a reason for this difference in delay. Problem 7 (2 points) In a wide-area network (WAN), what are the two key benefits of using a centralized SDN controller for traffic management over the traditional distributed controller? Problem 8 (2 points) Consider a Push-In-Extract-Out (PIEO) scheduler. Suppose there are 8 packets (A)--(H) queued with rank and (t_{eligibility}) values as shown below. Given this, fill the table below with the packet that will be scheduled at each time (t) by the PIEO scheduler. If no packet is scheduled at time (t), enter "None". Note that once a packet is scheduled, it is removed from the queue and cannot be scheduled again. Congratulations, you are almost done with this Midterm Exam.
