- Q2.Recently QUIC protocol is suggested. a. Elaborate on the advantages of QUIC through an example scenario. b. The standard protocols, like TCP, UDP and HTTP, are implemented in various languages. For example, Java language has ServerSocket() class for TCP server. Does the QUIC protocol is supported in any language? I mean its library is available. If yes, please explain its working. And run a simple QUIC client program, even if this program is available over the Internet. c. List the servers supporting QUIC protocol, if they exist.Below is example simulation based on Cisco Packet Tracer! Try to make an interconnection between 3 pieces of network that are connected to a router. Innetwork-1 has a DNS Server and 1 workstation, on network-2 there is an HTTP Server(.com domain) and 1 work station, on network-3 there is an HTTP Server(on the domain .com) and 1 work station. Do such a configuration so that each work station can access the existing server services on the three those networks?IN PYTHON Given the following six-node wide area network for which the numbers attached to the links are a measure of the “delay” in using that link (e.g., some lines could be more heavily used than others and therefore have a longer wait time), answer the following question. What is the shortest path from node A to node D, where shortest path is defined as the path with the smallest sum of the delays on each individual link? Explain exactly how you went about finding that path.
- A telephone company plans to connect its switching centers together using fiber optics. When connecting switching centers, it is required to have a path between every pair of them. The telephone company is looking for an interconnection topology that minimizes the amount of fiber required to connect its switching centers, describe an algorithm for this case.A businessman implemented a locking mechanism for the main door using an IOT-powered smart door lock where the VAULT and supplies for the business are stored. The smart door lock is implemented by keying in a 5-digit alphanumeric passcode to open the door and the self-locking mechanism allows the password to be utilized once and is reset when the door is locked again. The store owner encodes the passcode via the network for the door to be opened. Moreover, whenever there is a need to get items from the protected room including the vault, the store manager requests the binary-represented passcode wherein which is passed on to the store manager using SMS using a binary stream that represents the 5 alphanumeric passcodes. The bitstream is utilized to make sure that it is protected and can only be decrypted by someone who knows the process of decoding the binary bitstream. The rules of encoding the binary bitstream follow these steps/information: Bitstream represents a 5-digit…Q2- You are designing a connection mechanism between two programs, sending packets of data over the internet. You are trying to choose a size for the packets to be sent, depending on the capacity of the channel (channel bandwidth). For example, if a channel has a capacity of 10KB, then you can choose a packet size of 10KB, and send one packet, or choose a packet size of 5KB and send two packets...Etc. The problem you face is that the two programs are at two different locations, with two different channel capacities. If the first channel had a capacity of 3201KB, and the second channel had a capacity of 4565KB, find the maximum packet size that is suitable for both channels.
- Please type the ans Imagine you are the network administrator of University X having N campuses in alaska. 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 2G - GSM mobile phone which has been turned off for a while. The user turns it on and tries to make a phone call to another mobile phone in the same mobile operator's network which is also a 2G network. Write down ALL messaging between various components of the GSM architecture and the mobile phone being turned on until the call is established (so do not consider the other side of the phone call) in a timeline with appropriate messaging and names of the channels being used. When making a phone call assume that the user fails in the first 2 random- access trials and succeeds on the 3rd random-access trial.ngineering Computer EngineeringQ&A Library2.1 Mbps. Assume that packets are of length 2.0 Kb (Kilobits) and the length of the link is 100Km. a. What is the propagation delay from A to B, that is the amount of time from when the first bit of the packet is transmitted at A, until it is received at B? b. What is the transmission time of the packet at A (the time from when the first bit of the packet is sent into the wire and the time at which the last bit is sent into the wire). c.
