- The following frame should be transmitted over a given network (the frame is shown in hexadecimal): 7E DB DD 7E C0 7D DB DC FF C0. a) If the SLIP framing protocol is used; what are the bytes that are sent on the wire (after framing)? Show your workUsing the process of ANDing determine the network ID of the following addresses: a. 192.168.3.115 255.255.255.240 b. 172.16.230.15 255.255.224.0 – use a spreadsheet and show work to receive creditConsider a distributed system where every node has its physical clock and all physical clocks are perfectly synchronized. Develop an algorithm to record global state assuming the communication network is reliable.
- If you're talking about a private network, what is the address of that system? If a datagram is sent from a private network, is it conceivable for it to end up on the open Internet? Explanation?Is that so, or not? Consider a TCP connection where the most recent SampleRTT was 1 second. It is recommended that the TimeoutInterval be set to more than one second.Using vlsm, subnet the network 192.168.42.0/24, there are 3 departments, ensure there’s enough address to accommodate the needs of each department. Department A has 70 hosts, Department B has 50 and Department C has 28, find the subnet, first host, last host, Broadcast id and Mask
- Your task is to compute a session key in a DHKE protocol based on elliptic curves. Your private key is a = 6. You receive Bob’s public key B =( 5,9). The elliptic curve being used is defined by y^2 ≡x^3+x+6 mod 11. \ no hand writtenName the protocols that are assigned to the following ports: Port 21: ______ Port 25: ______ Port 80: ______ Port 110: ______The critical path of a network is the the shortest path (in time) from Start to Finish True False
- QUESTION 6 BGP is used to compute the shortest path in an Autonomous System (AS) True False 5 points QUESTION 7 Applications directly interacts with services provided from network layer. True False 5 points QUESTION 8 TCP provides a guarantee on the timing. True False 5 points QUESTION 9 UDP communications are secure by default. True False 5 points QUESTION 10 Http protocol is an example of stateful protocols True FalseAs another example, consider a circuit-switched network that connects computers in two remote offices of a private company. The offices are connected using a T-1 line leased from a communication service provider. There are two 4 × 8 (4 inputs and 8 outputs) switches in this network. For each switch, four output ports are folded into the input ports to allow communication between computers in the same office. Four other output ports allow communication between the two offices. Figure shows the situationA TCP connection is using a window size of 8,000 bytes and the previousacknowledgment number was 10,001. It receives a segment with acknowledgment number 12,001 and window size advertisement of 7,000 bytes. Draw a diagram to show the situation of the window before and after.
