Windows server is Internet Protocols (IP) Transmission Control Protocol (TCP) User Datagram Protocol (UDP), Hypertext Transfer Protocol (HTTP), and File Transfer Protocol (FTP) are just a few named. During the configuration of the network switches and routers the ports that these protocols use to communication must be opened for sending and receiving packets through those ports or nothing will work this is known as the IP routing scheme. Other protocols that are considered lower level are…

without there being too much downtime. Performance in an enterprise network can be a different story, specifically with the router situation. One of the biggest issues would be making sure there isn’t too much bandwidth on a given router. If we had multiple applications that required a lot of bandwidth, expanding to multiple routers and pouring traffic through those different routers would be…

sniffer can obtain copies of broadcast packets sent over the LAN. As described in Section 1.2, cable access technologies also broadcast packets and are thus vulnerable to sniffing. Furthermore, a bad guy who gains access to an institution’s access router or access link to the Internet…

operators to make changes to the network infrastructure without sacrificing network availability and at the same time reduces network maintenance costs by providing a centralized point of control and one unified user configuration interface for switches, routers and middle-boxes1 from diverse vendors [2]. According to Sarah Sorensen, the author of the book of “The Sustainable Network”, “SDN tackles the barriers that constrain scale, automation, and agility by decoupling the forwarding layer from…

TWC will provide primary service and AT&T will provide backup service if TWC service is down, the routers are configured to automatically switch between the connections when down, to reduce the amount of time the IT staff must deal with this. TWC will connect to Cisco switch #3 in the network drawing and AT&T will connect to Cisco switch # 1. The internet…

equipped with satellite and terrestrial antennas but routes tree nodes' video traffic using the WiFi (802.11n) link from source nodes. If nodes communicate over WiFi (802.11n) then connectivity is formed on orthogonal channel using pair of 802.11n routers. However,if nodes communicate over LTE, it share resources over a single channel. For sake of simplicity following assumption is made: \begin{itemize} \item Satellite/terrestrial communication has sufficient bandwidth to satisfy the…

1-What factors will help you decide if the existing internetwork is in good enough shape to support new enhancements? keeping a track of round trip response time, regular checkups of major routers, firewalls and switches, identifying sources and destinations of network traffic, analyzing its direction and balancing the data travel between source and destination are the some important factors. Documentation should be done for Data stores and traffic flows, the number of stations, average time a…

Unit 24 Task 4 – Open and Closed Loops What an open loop system is: An open loop system is a system that is designed to achieve a specific result and it is designed to be run again and again, but there is no way of tracking if the result has actually been attained. This is because open loop systems do not check if the goal has been reached. Three examples of an open loop system: Light switch TV Remote Toaster Why each system can be seen as an open loop system: Light switches can be seen as an…

Step1: Start the program Step2: Initialize the nodes by fixing the number of nodes, type of antenna used, type of routing protocol and plotting circumference Step3: Frequency is allocated for the MIMO antennas. Step4: Positioning and plotting the nodes Step5: Base Bandwidth allocation for primary and secondary nodes • Primary network range- 2.4GHz - 2.485GHz • Secondary network range- 433.4MHz - 473MHz Step6: Setting time for node movement to move and setting the destination Step7: Traffic is…

In this section the fast-recovery algorithm that makes TCP NewReno[1] perform better than the Reno[3], is described. During congestion avoidance if the sender receives triple duplicate ACKs, then it performs fast-retransmission and enters into fast-recovery. In fast-retransmit the sender retransmits the lost segment,sets the threshold value for slow-start as ssthresh = cwnd/2, and sets congestion window, cwnd = ssthresh+3 segments. In fast-recovery, the sender increases its congestion window by…
