- In Cisco Packet Tracer, I have three routers (A, B, and C). B and C should be in a cluster; this cluster should have one IP address: 205.128.216.18. A, which should have an IP address of 172.167.5.8, should only use one cable to connect to the cluster.QUESTION 78 Consider the network shown below. Suppose all ASs are running OSPF for their intra-AS routing protocol. Suppose EBGP and IBGP are used for the inter-AS routing protocol. All links in any AS has the same weights AS1 AS3 1b 1a 3b 1ç 110 30 19 За J11 3d AS2 12 114 2d 113. 4b 16 2a 15, 20 2b AS4 a. Router 3c learns about prefix x from which routing protocol? b. Router 3a learns about x from which routing protocol? c. Router 1c learns about x from which routing protocol? d. Router 4b learns about x from which routing protocol? Assuming AS1 and AS2 uses hot potatoes routing What woud be the entry for x in the 2b routing table? What would be the entry for x in the 2d routing table? What would be the entry for x in the 1c routing table? How AS2 can restrict AS1 from routing to X via AS2?Consider this multihpop network running the 802.11 MAC protocol in ad-hoc mode (RTS-CTS-DATA-ACK) and a link speed of 1 Mbps: A === B === C === D Edges ‘===’ represent connectivity, so, for instance, nodes B and C can communicate with each other directly, but A and C cannot. All nodes are able to route packets on behalf of the other nodes and they employ store-and-forward to deliver packets to the destination. Suppose nodes A, B, and C have to send a lot of data frames to node D and have their link layer queue always full. What is the average data rate for A, B, and C assuming no DATA frames get lost due collisions? Explain your answer. Compare the data rates with the link rate.
- The maximum packet size (Maximum Transmission Unit or MTU) of an IP packet including IPv4 header on 100 Mbps Ethernet is usually set at 1500 bytes. A typical IPv4 header consists of 20 bytes, and a UDP header consists of 8 bytes. If we split up a file of 20,000,000 bytes so we can send it as a series of UDP payloads, how many IP packets do we have to send in order to transfer the entire file? Enter an integer number without formatting (no commas).

The Ethernet header is 14 bytes and the frame checksum is 4…Consider a home network connected to the Internet through a single home router that supports the Network Address Translation (NAT) protocol. The ISP is only providing a single public IP address to the owner of this network (82.7.30.73). Let us assume that one of the connected home devices with IP address 192.168.0.1 has an open connection from source port 30000 to a web server with IP address 172.217.169.4. The source IP and port of the incoming TCP segments that the web server sees could be: 192.168.0.1, 30000 82.7.30.73, 5555 192.168.0.1, 5555 172.217.169.4, 80

- Imagine you are the network administrator of University X having N campuses in Towson, Maryland. You want to build a connected network of servers (each server is either a regular or a routing one), one at each campus, and want to choose some of them to be the designated routing servers. A routing server will serve regular servers who connect directly to it via high speed cables, and every regular server must connect to at least one routing server. Your goal is to minimize the total length of high-speed cable that you must purchase. Given the geographic locations of the N campuses, design a plan that requires (1) the shortest length of cable and (2) the least number of routing servers. Analyze the time and space complexity of your procedure.Consider a router that interconnects three subnets: Subnet 1, Subnet 2, and Subnet 3. Suppose all of the interfaces in each of these three subnets are required to have the prefix 223.1.17/24.

Provide three network addresses (of the form a.b.c.d/x) that satisfy these constraints. Please provide a short discussion justifying your answer.Suppose we have a web page which contains 10 objects including: a html main file, 8 jpg image, and a .mp3 background music. For simplicity, assume each of the 10 objects has a size of 4 Kbits and that each object can be completely transferred in one TCP packet. Furthermore, assume the round-trip time between the server and client is RTT= 250 ms, and the download rate is 1 Mbps. What will be the time it takes to complete transferring the web page running in the non-persistent mode? Total delay = ms
