SDN are next generation networks. They provide high flexibility, reliability, and security. The main difference between SDN and the traditional network is separation of control and data plane. In SDN, only the controller has the decision-making capabilities. Whereas switches are responsible for traffic forwarding. The controller and switches can be programmed dynamically or as needed. Applications communicate directly with the SDN controller via the northbound interface. This plane is also…

the switch will flood the LLDP packets to all enabled ports; Thirdly, when another switch receives the LLDP packets, it will send the Packet-in message with the payload of LLDP packets to the controller. Under this procedure, the switch cannot prevent the host to get the LLDP packet. However, if the host can reach two switches, the host can act as the transparent cable or wire to let the LLDP packet pass through. For the behavior, the host can inject the modified LLDP packet into the network or…

capstone project on a network upgrade and redesign project my company completed to update the local area network (LAN) from Gigabit Ethernet to Ten Gigabit Ethernet. The project was inspired by my company’s decision to virtualize its data center, update its physical security system, and expand its passenger processing system. All these technologies require a robust network to.... Additionally, the network firewalls were outdated and lacking security features that protects the network against…

Plane which is responsible for programming and managing the Forwarding Plane. Control Plane makes use of the information gathered by the Forwarding Plane in order to define the route and operation of the network. It is composed of software controllers that communicate with the forwarding network fundamentals through standard interfaces, referred also as the South Bound Interface. The last layer is called Application Layer which takes care of…

narrowing down the overall issue with the connection. Since VoIP is a network connection, any packet tracking software will help in troubleshooting connection issues. There are a number of freely available tools such as Wireshark, Capsa, Microsoft network monitor and even and old tool called tcpdump. All of these tools will capture the packets traveling on your network. If you capture them from different points on your network you can determine where the issue is occurring. Wire shark can show…

also works quite well to network computers, allowing the computers in a home to share files, internet access, and printers. The ability to share a printer over a network is extremely helpful. Rather than having to maintain multiple printers, (which will work less well if they are not used regularly) you can save space and money by connecting all your computers wirelessly to one centrally located printer. Here 's how to do it: To begin with, you will need a wireless network. If you don 't…

A general definition of a home network would be the interconnection between two or more computers to establish a local area network inside the home. With the advancement of the technology, the notion of computers has changed because many devices can do the same job that computers do. Therefore, let us define a home network as a local area network that allows digital devices present inside of a home to communicate together. We will enumerate a list of Home Network devices and we will write…

A network allows computers to exchange data. In computer networks, devices exchange data using a data link. The connections are made using cable or wireless connection. Maintaining network security throughout an organization can be quite challenging and is indeed a tough job, but it is attainable and can be achieved. Network security is all about keeping the network safe for all devices and computers on the system. There are certain measures and skills needed to keep a network safe. There are…

Inc. is a quickly growing company looking to upgrade its current network. The company has grown from 5 to 200 employees in the past year and a half. The company is expected to grow to 350 employees in one year. ABC Accounting, Inc. will add more offices in the current building, which will span three floors. To accommodate their growth ABC Accounting is seeking the necessary solution to build an affordable, expandable, and secure network. This proposal will provide a comprehensive and secure…

This diagram illustrates a Local Area Network implemented using an Ethernet connection on a bus topology model. It is a LAN because there is no indication of considerable distance between the computers or departments. It is in Bus topology as since the computers connect to the network by connecting to the network cable. This as opposed to a star network topology setup. Next to each network component is an Internet Protocol (IP) address. Each IP consists of four number whose value can range from…
