Part E Switch Technology Introduction In appearance, a switch is simple, just a case of having a number of ports, that can be connected with a variety of different devices such as workstations, routers or other switches through these ports. When a packet arrives at one input port, the task of the switch is to decide either to discard the packet, or move it to the correct output port for transmission. The correct output port is determined the packets according to the information carried in the packet

I configured in Cisco Packet Tracer. In RIP a hop is counted as a metric from router to router. So if the source in this example is “PC-Jemine1” with the destination being “PC-Jemine2” RIP would use a hop count of 5. This would be: ➢ Source =PC-Jemine1 ➢ Router 0 to Router 1 = Hop Count 1 ➢ Router 1 to Router 3 = Hop Count 2 ➢ Router 3 to Router 5 = Hop Count 3 ➢ Router 5 to Router 8 = Hop Count 4 ➢ Router 8 to Router 7 = Hop Count 5 ➢ Destination = PC-Jemine2 The network I have designed in figure

Discussion Assignment Unit 4 In Unit 4, we are introduced to the functionality offered by routers and switches Explain how MPLS VPN’s create tunnels Introduction: According to Marsic (2010), “Multiprotocol Label Switching (MPLS) is essentially a mechanism for creating and using special paths, known as “tunnels,” in IP networks”. MPLS is designed to speed up and shape the flows of network. MPLS is a set of protocols rather than a single protocol whose key protocols are Label Distribution Protocol

What is one stock or bond you would buy and why? (500 words) The stock I would purchase would be Cisco Systems (NASDAQ: CSCO), the leading provider of enterprise networking hardware, at $40.82 per share down from $49.93 pre-COVID-19 (about 18% decrease). Cisco provides IT products across five industries: Networking, Security, Collaboration, Data Center, and Internet of Things (IoT). Essentially, Cisco is the backbone of the internet through its products. Despite revenue falls in Q4 and expected

The company that I’ve decided to research is Cisco. The name Cisco comes from San Francisco from where the company has originated. Cisco produces network based products which enhance the usage of internet such as routers and programs for virtual communication. Cisco has taken over more than 120 different companies in order to offer new technological products. By using Michael Porter’s (1980) 3 generic business strategies, I was able to identify that Cisco uses a differentiated strategy. The differentiation

Appendix B: Guidelines on Firewalls and Firewall Policy Firewalls help shape network architecture by splitting a network into smaller subnetworks for improved security. That being the case, AAE separates the PCI systems by creating individual VLANs/security zones and putting firewall security policies between them and the other networks. These criteria also apply to the 4500X switch...In a like manner, the core switch further develops the network topology by ??? The switch placement is also important

Understand physical and logical network topologies 1.1 Describe common physical network topologies There are 7 most common topologies that most people will use. The first one is a ring topology this works with 2 or more of the host in a circle by passing a token around the token never stops moving it will grad the data that need to be attached and take it to that giving computer mac addressee. The second one is a Mesh topology. This topology works by ensuring that every host is connected to

7 Telecommunications The telephone is one of the most important means of communicating with the outside world. It is also frequently used for contacting members of staff within an organisation. 7.1 The advantages of telephone communications The telephone has a number of advantages: • The most important is the speed with which people can be contacted and the ease of use. • It allows instant feedback and is considerably more personal than written correspondence such as letters or emails. • Short

Step 1: Create a cluster having N number of nodes using the formula Cm,k. For all m=0,1,2……N-1 K=1,2,……...logN Step2: Assume that all the nodes in the network can i nitiate the diagnosis and all the nodes are fault free at the initial stage of algorithm execution. Step 3: Start the Diagnosis process: Repeat for K=1 to log N Do Send i_hb( p, q , Dq, init_hb_msg) Set_Timeout (Tout) Step4: Find out response time and tested node response r_hb (q, p, D’q ,res_hb_msg) if Dq = D’q, // then

with less. Cisco's mission statement was to be the supplier of choice by leading the competition in the order of customer satisfaction, product leader, highest market share and maximum profits. Cisco has a lot of product categories. These include routers, switches, firewalls, data centers, nexus switches, storage. Cisco also has a certification program that develops networking engineers based on Cisco technologies. Cisco is the biggest networking company in the

Pros & Cons Pros • Easy to install: Wireless networks have become commonplace with Wireless N being the current standard. Wireless router is easy to purchase, connect it to the Internet, and install in either at home or office setting, it is recommended to hire a network professional to install and setup the wireless router in order to ensure that you have high level of security enabled and there is sufficient wireless coverage throughout the whole areas. • Cost: The cost of the hardware is low,

There is several different types of components that enable the internet and help the web function correctly upon your computer. A few of these things are; Uploading and FTP, Web Servers, network routers, proxy servers, ISPs, Web Hosting Services, and Domains. I will be explaining all of these components in as much detail as possible. Uploading This component is when you transmit any file from one computer to another computer, this is usually a much larger file. Most of the webs users would explain

Network monitoring now is limited because of the number of servers it takes to deal with the large influx of router data. Router manufacturers have been attempting to combat this by adding counters to the routers that report on the number of data packets a router has processed during some time interval, but adding counters for every special task would be impractical and put more stress on servers since they would need thousands more to process the flood of data coming in. To combat this a system

To ensure the wireless signal is transmitted to every corner of the office space I recommend routers set-up with 4 directional antennas and a centralized Omni-directional antenna. The use of 2.4 GHz routers will increase data transmission speed 460-600 Mbps and provide 11 channels per router to support decrease in network collisions and prevent data packet from being dropped (Lazar, n.d.). All computing devices must be equipped with latest Windows 10 for business and use VPN tunnels to remotely connect

are. And explain how various networking concepts (bandwidth, routing, routers, and the client/server model) either are being or could be used to meet Walmart’s networking needs. The components of Wal-Mart system consist of the following: a) A bunch of computers in which to store the customer’s name, the number of items bought, the price of each item, including calculating the bill. b) Router/routers – They use 1 or 2 routers in order to give WIFI from the LAN network to actually gain means to entry

design process, and we learn to utilize the process in various applications. When we progress throughout the pathway, we delve into more of the specifics in regards to computer networking. With computer networking, we developed an understanding of routers, switches, networks, and other components that all seem to interconnect with each other in order to ensure that everything is functioning properly. This would be the basis of information that was taught in class, but a few concepts especially

connecting to the network. All wireless protocols need to be at least WPA2 because of how many tools are out there and older models can be cracked. Router encryption: A router is a gateway to a network. The default password and username is public knowledge for most models. A typical attack, if a hacker gets into the router, is a DoS (Denial of Service ) attack. Router encryption blocks any good traffic coming in for the system is too busy with all the denials it has to send

1. Goal The primary purpose of this lab was to get familiar with RLES and establish a base infrastructure. This infrastructure includes a router/firewall and Linux server for network monitoring and documentation. Network monitoring is crucial in any infrastructure, no matter how small or how large. Without it, there is no way to know a system has gone down until users start complaining. With it, the system/network administrator can be aware of the issue the instant it happens. Documentation is also
