Physical Network Design
1. Network Topology
The purpose of this paper is to present a proposal of network architectural system; it explains analysis of a detailed network arrangement with the networking infrastructure. This paper includes the study of physical topology according to the business needs for establishing a network layout such as premises of campus of “University of Maryland” is connected along with the departments, library, rooms, laboratory, and grounds with the network connections. The data must be secured for the campus teachers as well as students through all network arrangements. The new network system should also take into consideration the future development of the campus with more labs, library, computer, classrooms other offices in the building locations. So the proposed layout of the network layout is worthwhile for University (Stewart, 2008).
A general layout of a network that is topological with a protected system linking within the campus of the college:
Business Needs
The Cisco Enterprise Specialist of the IT Business association is for IT professionals to help them provide their business with innovation to improve their business output. The IT experts will groom their skills as part of this association such as:
· Assessing the technological alternatives within a business connection
· Evaluating and meeting the business needs.
· Behaving and talking courteously with business peers.
· Getting knowledge about an aggregate expense of proprietorship and an arrival on speculation IT arrangement's (Eernet, (n.d)).
Proposed topology
It is important to keep the system documentation brief and comprehensive. Initially, at the establishment of a system, the system documentation is generally concise, but when the system changes or develops more, the documentation needs to be redesign. System topology maps usually present a unique floor arrangement. When there are changes in the floor arrangements, the necessary steps are taken to change the Diagrams or redline are created to demonstrate the alterations. The changed layout is organized and well presented. An outline that is as-assembled represents how actually a system was created, which can be further altered. It is guaranteed that the existing records reflect the all systems topology changes and arrangement of the as-manufactured floor.

Justification for proposed network topology
The Cisco Services – is a global level organization having more than 9,500 workers in more than 120 countries with more than 380 locations – Cisco Enterprise Architecture Services has a trustworthy public image due to best practices, industry based technological developments, and brilliance. Cisco maintains various network emergency response vehicles (NERV)’s that are deployed by the Cisco employees in case of natural disasters or public crises. Cisco Enterprise Services helps the companies to seize the opportunities of tomorrow by providing amazing networks and connections. (Cisco.com, 2016).
2. Network Media
Network media is a path that is actual over which signals that are electrical travels as it passages from one site to another within the campus or an organization. Network Media provides communication channels for interconnecting devices on the computers or on a data communication network. The most widely used network media’s types are wireless, twisted pair cables, fibre-optic cables, and coaxial cables. Every media type has specific characteristics that meet the particular needs. Star topology is a common type of topology used in offices and home. (Cisco Systems, Inc., 2016.).
Business Needs
Organizations' employees such as college or campuses employees are getting knowledge through various certified programs as part of their business practices to create workers efficiency, improve coordination, reduce costs, and to streamline and upgrade business operations. These practices are continued because organizations are moving towards green IT that helps the organizations to work more efficiently, optimize their infrastructure and operate in a more environmentally sustainable way. Network infrastructure is a critical part of the business process. It is important to optimize the performance and standardize the network to prevent frequent network outage. The network system must respond to the needs of the system applications and scope of media. All applications necessitate system’s utilization hardware to cut down the cost and streamline the business operations. IT solutions and network structure responds to the changes more quickly and improves the ways the businesses manage, share and use knowledge in their business. System applications are designed to meet the specific user needs and to improve productivity and to perform the business functions accurately. (cisco.com)
Proposed Network Media
The different diagrams are leveled an approach of building square using a quickly directed focus framework coat to which are linked distinctive open movement fragments. The course incorporate pieces two switches’ layers: the genuine assignment centers that drive about as wiring closet entrée switches and aggregators.
Justification for the selected network media that meet the business needs
For systems, those are using the access to the layer three exchanging in of their pieces of the appropriation advice that a total involved convention directing, for instance, OSPF and EIGRP be the actualized as the IGP. The using OSPF and EIGRP end to end in of the bases provide rapid merging. It is clear that to internal failure better adaptation comprehends preferably and reasonability over an outline utilizing RIP or static directing or an outline that effects a blend of direction-finding conventions (for example, RIP reallocated into OSPF).
3. Network Devices
Business Network Devices
Setting up a network for business devices infrastructure has come into easiest more than the years as the network technologies have been improved. The network allows sharing an internet connection of single broadband over multiple PC and computers users. After a system network has been established through devices, the businesses need to protect it using security settings in the routers or the operating systems. This limits the access to the authorized users. (Cisco.com, 2016).
Proposed Network Devices
These are the proposed system gadgets that are utilized as a part of the current system plan.
Network Switches are a PC sorting out the device to partner contraptions to a PC framework by using package changing to get, handle or forward data to the objective device? A framework switch is a multiport of Network Bridge which uses gear to get ready and forward data. A regular sort is Ethernet switches that channel drawing closer data from various wellsprings of data port to a specific yield port to pass on data to the objective contraption.
Routers, it is a frameworks organization device that advances data packs between PC frameworks. They play out the bearing development limits on the web. A switch is connected to two or more data lines from different frameworks. The most surely understood sorts of switches are little office switches that fundamentally pass IP bundles between the PC and web (Sans.org).
Justification for the selected network devices
John Chambers starting late saw, "In the next decade or two, associations will bring a radically new level of headway to us: the ability to drive proficiency at results that are 5, 10, conceivably twelve times more vital than whatever we have discovered already. Additionally, one of the advancements that help them extends the estimation of their trades, and to move from trades to correspondences, is the framework (cisco.com)."
4. Network Security Devices
Business needs
The network security plan ensures that data access is limited to authorized users. The dynamic nature of network security threats needs dynamic multipoint security solutions. Network security system with monitoring capabilities gives IT organizations a powerful weapon for fighting cyber threats. The overall security preparation must include an IT infrastructure that describes how an organization guarantees its data resources and system. The arrangement IT network security can contain methods recognized with these:
· Incident taking
· Intrusion checking
· Remote access
· Permissible programming
· User confirmation (Pearsonhighered.com)
Proposed Network Security Devices
A firewall is an essential needed framework that can block traffic based on IP protocols, IP address or a port number. It goes about as a check between a trusted framework and other untrusted frameworks. A firewall controls access to the advantages of a framework using a positive control model. The soonest firewalls functioned as group channels that evaluate the packages which are traded between PCs on the web. Exactly when a pack has experienced a firewall, the benefits and objective location close by traditions and objective port are checked against the standard firewall set.
Fig. A firewall arrangement in the organization campus
Justification for the proposed network security devices
By utilizing a firewall, secure topologies are often established. A firewall protects one structure from another malware framework. This protection system works mostly on the OSI reference model first three layers that are data link, physical, and network (Swathe, (n.d)).
5. Computer Systems
Business Requirements
A PC structure is a game plan of interconnected PCs which can share a central stockpiling system and diverse peripherals contraptions, for instance, scanners, switches, and printers. Each PC connected with the structure can work independently while having the capacity to talk with other external devices and PCs.
Proposed Computer Systems
The operating system installed on a computer affects the business in a major way, particularly when other computers are connected to the business network. PC frameworks are fundamental parts of basically every affiliation. They make, present, and reinforce an affiliation's PC structures, involving (LANs) neighborhood, wide zone frameworks (WANs), framework pieces, correspondence data system and intranets.
PC frameworks hardware and communication traditions created through time: the "System Control Protocol” progressed to the four layer TCP/IP (1978) tradition stack. The TCP/IP got the opportunity to win in contradiction of the psyche layers of the boggling seven "OSI" stack planned (1977) by "ISO," exorbitantly difficult for use and interoperability. A viewpoint of the “IETF” and “IEEE” traditions stacks (Stewart, 2008).
Fig: Required Computer Systems for the proposed network arrangement
Justification for selected computer systems
A framework system proposed by Paul Baran in light of centers that forward group or datagrams from different customers over a distinctive line of PC structures from starting to goal. Package trading perspective provides the quality of framework in contradiction of framework center point disillusionments, the independent coordinating of datagrams per center makes possible that the datagrams accomplish their goal even in the region of various center point frustrations.
II. Network Addresses Design
1. Subletting in the Network
Business Needs and their assessment
A subnet MASK is used to show which gap of the IP address perceives the framework and which separate recognizes a specific host on the framework. This may give off an impression of being unnecessary at first since the underlying three amounts of an IP address starting from the left, (for instance, 192.168.1) reliably recognize the framework, and the last number constantly recognizes an individual device in frameworks, for example, the one in our specimen, which is known as a "standard Class C" framework. Regardless, this is not substantial for various frameworks. That is the reason subnet cover is used to isolate the framework fragment of the address from the host portion (Cisco, 2016)
Proposed Subletting (include the calculations)
IP addressing to and subletting are an important piece of systems. We have explored that how IP addresses works, subnet veils, glassful versus tactless IP addresses, default portals which are only the tip of the iceberg. Subletting allows business to prepare multiple sensible systems that exist inside of a solitary Class A, B, or C system. For the chance that one doesn’t subnet, you are just ready to utilize one system from your Class A, B, or C system, which is unreasonable. Every information available on a PC system must have an exceptional system ID, with each hub on that connection being an individual from the same system. With regards to a casual that you break a noteworthy system (Class A, B, or C) into littler sub-networks, it documents you to make a system of interconnecting subnetworks. Each data join on this framework would then have a noteworthy framework/sub network ID. Any contraption, or entrance, interfacing n frameworks/sub-networks has unmistakable IP addresses, one for each framework/sub network that it interconnects.
Keeping in consideration the final aim to subnet a framework, increase the general spread using a rate of the bits from the host ID fragment of the area to sort a subnetwork ID, For example, given a Class C arrangement of 204.17.5.0 which has a trademark cover of 255.255.255.0, you can make subnets in this way:
204.17.5.0 - 11001100.00010001.00000101.00000000
255.255.255.224 - 11111111.11111111.11111111.11100000
Justification that fulfills the address network design for the campus network structure
By extending the cover to be 255.255.255.224, you have taken three bits (demonstrated by "sub") from the first host segment of the location and utilized them to make subnets. With these three bits, it is conceivable to make eight subnets. With the staying five host ID bits, each subnet can have up to 32 host addresses, 30 of which can really be allocated to a gadget since host ids of all zeros or all ones are not permitted (it is imperative to recall this). Along these lines, because of this, these subnets have been made (Stewart, 2008).
III. Network Services Design
1. Network Services
Business Needs
The important and ultimate aim of the service network design can be characterized as follows:
· Data rates keep increasing
· Protocols and applications keep evolving
· System implementation and testing take too long
· Provides detailed instructions and resources for creating and managing online computer labs
· Explains how to develop fully functioning Linux network systems with open source materials
· Supplies professors with instructions and resources to create and manage online computer labs as well as supplemental instructional materials
· Provides an effective, low-cost alternative to traditional proprietary-based network systems
Creation and maintenance of a fully functioning enterprise network system are not an expensive deal. The technical goals of the network are to meet customer needs efficiently. It is important to have to understand of network architecture, topology, protocols, and services of local and wide area networks.(ucisa.ac.uk)
Proposed Network Services
Mentioned below are the proposed customizations needed to develop a system design network
· Security
· One central location for Backups
· Hardware, Network, wirelessly scalability
· Disaster Recovery
· Allows the IT expert to work remotely
Justification for supporting these network services
Critical business applications and processes are impacted by the unpredictable network availability, so the network systems need to be ensured that it is reliable and predictable. Networking and communication costs are a perennial concern for the organizations and one of the most important factors for implementing new network system design. In-house technical expertise could be better used to progress business projects rather than manage network monitoring and availability issues. (Cisco.com)
2. “Network Security Measures”
Business Needs
In an increasingly sophisticated threat environment, organizations need to ramp up their network security with firewalls and virus scanners. With the widespread growth of complex networks, security has never been more important or widely discussed. Nearly every day, headlines about the most recent data breach populate the news cycle, and consumers are as wary as ever. Having an overall view of what it takes to build and maintain secure infrastructure is essential in order to keep today’s businesses up and running safely. Fortunately, there are various options available that make it possible to implement productive security controls for any size company.
Proposed “Network Security Measures.”
System Security Software: Antimalware includes Sophos Endpoint Security and Control 7.0, McAfee Total protection for the enterprise. On the other hand application security includes IBM WebSphere Data Power XML security gateway XS40, F5 networks BIG-IP Application Security Manager. Digital identity verification can be done through Juniper networks Steel belted Radius Server.
Network Firewall: As far as PC security, a firewall is a bit of programming. This product screens the system activity. A firewall has an arrangement of guidelines which are connected to every bundle. The guidelines choose if a parcel can pass, or whether it is disposed of. Typically a firewall is put in a system that is trusted and one that is less trusted. At the point when an expansive system should be secured, the firewall programming regularly keeps running on a PC that does nothing else. A firewall secures user in the system against unapproved access.(Lewis).
Secured Wireless Network:
Most network devices, including wireless access points, are pre-configured with default administrator passwords to simplify setup. Changing default passwords makes it harder for attackers to take control of the device. Moreover, encrypting the data would prevent anyone who might be able to access your network from viewing your data
Back-up or Reinforcement Solutions: System reinforcement normally requires a customer server programming design. The reinforcement server lives on a brought together server and the reinforcement customers dwell on each framework to be supported up. Advanced system reinforcement frameworks can oversee reinforcement media which are likewise associated with the reinforcement server by means of a network. Network reinforcement frameworks are considerably more versatile and sensible than neighborhood reinforcement frameworks where tape drives are connected to every PC framework.
Patching and Programming Maintenance: Another real security issue is to maintain the programming through software such as Astea Alliance, MaintiMizer, Man Win, upkeep, Fixed, Rosmiman IWMS and Net Dispatcher, etc.
Justification that these network security steps are fulfilling the business needs
The need for having network security can never be denied. With the network security systems each file, data, and information are kept safe and protected from unauthorized access. This is the reason why it is widely used in businesses and many other organizations.
· System Security helps in ensuring individual information of customers’ existing on the system.
· Network Security encourages insurance of data that is shared between PCs on the system.
· Hacking endeavors or infection/spyware assaults from the web won't have the capacity to hurt physical PCs. Outside conceivable assaults are anticipated.
