Introduction

Networking is indeed the digital connection of machines for the exchange of data. Resources including files, programs, printers, and programs are some of the often information exchanged in connectivity. As networking enables user interaction across a large range, its benefits in the areas of security, efficacy, scalability, and economic viability are evident. Data is sent from one location to another through various technologies, such as cable and radiofrequency, employing switches and routers. A LAN network is made up of multiple computers connected together over a short distance, usually at a person's house, place of employment, or place of study. In addition to towns and countries, a network known as a wide area network (WAN) generally encompasses the entire globe (Teng, 2015). A WAN could be built by fusing many big LANs together. It is essential to avoid data collisions whenever connected devices attempt to access the very same transmission medium due to the numerous connected devices. A set of principles called as bearers sensing enable the formation identifying have been utilized to detect as well as reduce the number of accidents in networks (Aliso, 2011). This essay discusses the LAN network design and WAN network design for Better Box Corporation.

LAN network design for Headquarters

A local area network, like any other telecommunication system for Better Box Corporation, is composed of the following three fundamental hardware components: a transmission medium, typically twisted pair, coaxial cable, as well as fiber optics; a method of control for transmitting over the form of media; as well as a functionality to the system for internal servers or other smart devices, or "nodes" of the network. Additionally, local area networks and long-haul packet telecommunication systems for Better Box Corporation both share a fourth fundamental component: a set of operating system protocols that are incorporated in the computer systems or even other wearable technology and regulate the information transfer through one server as well as device to the next through the channel's hardware components. Such software protocols are an essential component including both local area networks and related family members, long-haul packet effectiveness. They operate at different levels, including low latency transport layer protocols to higher discharge interfaces.

Workstations and interconnecting devices

The Better Box Corporation makes cardboard packaging. The group's main office is located in Chicago. Three divisions make up the corporate office: sales, advertising, and IT assistance. The marketing and selling divisions are on the second and third levels of the building, correspondingly, whereas the IT support is located on the first floor. There are 50 workstations in selling, 10 in advertising, as well as 20 in IT support. So it is important to have the workstations on all three divisions with interconnecting devices.

Media types

Pulling polymers or glass to a thickness of only a hair's width results in an elastic, translucent fibre called as an optic fibre. Better Box Corporation uses fibre optics most often to convey light from the two ends of the fibre in fibre-optic telecommunication, which enables transmission over large distances and at rates (download speeds) than power cables. Because of their lower signal attenuation and resistance to electronic radiation, which metal wires are more prone to, fibres are used in replacement of metal wires. Fibres are typically packaged so that can be utilized as in the case of a fiberscope, to transmit light through it or images out of confined spaces. They are also used for illumination as well as cinematography. Among numerous other applications, fibre optic sensors as well as laser diodes are other applications for specially designed fibres.

The wavelengths used for optical fibre communication are located in the near-infrared spectrum, which is slightly above the visual spectrum, and are therefore invisible to the bare eyes. The typical frequencies for optical signals are 850 nm, 1310 nm, as well as 1550 nm. Optical fibre is used to transport light using the other lasers as well as LEDs. For 1310- or 1550-nm single-mode applications, laser are generally installed. For 850- or 1300 nm, LEDs are employed. This will be most suitable for Better Box Corporation.

LAN topology and protocols

Since LANs are broadcasting companies, each LAN station can hear every transmission made over the channel. LAN topologies must accommodate the network's broadcasting characteristics in Better Box Corporation and offer complete connection among all locations of Better Box Corporation. This physical topology refers to the actual connections that enable communication between LAN stations. This logical topology explains how well the LAN's broadcasting character is truly impacted and, consequently, how stations take part in the procedure to request authorization to broadcast on the media. LANs typically use one of three configurations: star, ring, or bus. All LAN gadgets are linked to one another through a central node in a star network. A circle-shaped network of point-to-point connects ties the nodes together in a ring network. All gadgets linked to a single electrical constant media in a bus network (Mitchell, n.d.).

Local site server access

It has now become important in this expanding network space to safeguard the network against unauthorized individuals and stop it from being hacked, thus it is necessary to keep information security in Better Box Corporation by utilizing numerous security options including security controls, cryptography, and the most safe routing algorithm. We need the greatest gadgets that can handle those protocol more effectively in order to put this into practice. Following a discussion, we choose to use layer 3 switches that can function as both routers and switches. This device can handle the EIGRP routing mechanism. EIGRP allows for packet forwarding and performs balancer on parallel links among sites.

Devices to be used and their functioning

Even though it's used for data routing across and within LANs like Ethernet as well as Token Ring, frame relay serves as the foundation for WAN connectivity in almost all companies so it will be suitable in Better Box Corporation (Aliso, 2011). The dispatch mechanism and, to a certain degree, the shipping containers, not the road, are what move packets of data from one location to another. All communications in circuit switching are divided into packet, that are then routed throughout several middlemen designated as packet switching exchangers to their destination. Every packet carry identifying data that identifies both destination and the source locations. The intermediate examines the packet's forwarding table at every pit stop, checks a forwarding table, and afterwards transmits the packet as promptly as possible to the following link on the chain going to the receiver. A high-performance, low-latency solution called frame relaying offers affordable LAN, WAN, Internet, as well as intranet links. It works best when transferring bursts of data of different sizes that demand top speeds (Latency versus Bandwidth, 2014).

Media types

Alternative terms for guided media include wired or limited wireless medium. The information that are currently conveyed along a particular path are controlled and constrained by physical links. Advantages include quick mobility, privacy, and to use over a small area. Uncontrolled or unbounded media are other names for the type of communication channels including social media called unguided media. Without the need for a storage device, electromagnetic information can be transported. Since the signal travels via the air, it is less safe but more effective when spread out over a larger area. in 2012 (Grigorik). Both the types are required in Better Box Corporation because of its capacity and buildings, but the better option for Better Box corporation is guided media as it is more safe and secure.

Type of network structure suitable

Network topologies come in two: physical and logical. Although logical topology stresses the structure of data transit among network nodes, physical topology concentrates on the actual arrangement of the linked nodes and equipment, so any network structure can be suitable for Better Box Corporation (Hoffman, 2011).

Recommended routing protocol

Link State Routing Protocols: Link state routing methods solve this problem in Better Box Corporation using an algorithms. Among the main differences between an intermediate nodes protocol and a distance vector method is that nodes in an intermediate node’s communication don't communicate out routing information; rather, they alert each other when a route varies. The neighbour tables, topological table, as well as routing table are the 3 kinds of tables that are created by routers that use the link state protocol. The topology database holds the entire topology of the network, the forwarding table contains the most effective routes, as well as the neighbour column saves information about adjacent routers that use the link state routing protocol (Smutz, n.d.).

Conclusion

This research has shown that it is possible to create a typical communications network at a lower cost in Better Box Corporation. Even though we just utilized the cheapest devices when building the system, it turns out that the security was really good. This is because channel's backups and security hardware are of high calibre. For all networks to function, numerous servers are required. Due to costs, we did not use all servers for our research, however we could use certain crucial servers like DHCP. These servers support the program's smooth operation of its operations. This study demonstrates how different expenditures were reduced in order to improve the designed network's performance. Even though there might have been some difficulties in completing this project because of financial limitations, we were ultimately successful in achieving our goal by creating a network for emerging universities at a low cost. For information security, for instance, we used a few gadgets, however the most intriguing thing is that, inside the end, all difficulties and limitations were surmounted.
