A general network topological layout with a protected system connection within the college campus:

Business Needs

The Cisco Enterprise IT Business Specialist 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 IT arrangement’s arrival on speculation (ROI) and aggregate expense of proprietorship (TCO) (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 as-assembled outline represents how a system was actually created, which can be further altered. It is guaranteed that the existing documentation reflects the as-manufactured floor arrangement and all system topology changes.

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 trustworthypublic image due to bestpractices, 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).

  1. Network Media


Network media is an actual path over which electrical signals travels as it moves 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 types of network media are twisted pair cables, coaxial cables, and wireless and fibre-optic 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 workersefficiency, 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 react to the requirements of the scope of media and system applications. All applications requireutilization of system 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 leveled diagram uses a building square approach using a quickly directed focus framework layer to which are joined distinctive free movement pieces. The course pieces incorporate two layers of switches: the genuine assignment centers that go about as aggregators and the wiring closet access switches.

Justification for the selected network media that meet the business needs

For those systems utilizing Layer 3 access exchanging within of their appropriation pieces, Cisco advice that a fullincluded directing convention, for example, “EIGRP or OSPF” be actualized as the grounds Interior Gateway Protocol (IGP). Utilizing “EIGRP or OSPF” end-to-end inside of the grounds gives quicker merging, better adaptation to internal failure, enhanced reasonability, and preferable adaptability over a configuration utilizing static directing or RIP, or an outline that influences a blend of steering conventions (for instance, RIP redistributed into OSPF).

  1. Network Devices


Business Network Devices

Setting up a business network devices infrastructure has become easiest over the years as the network technologies have been improved. The network allows sharing a single broadband internet connection over multiple computers and PC 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 computer networking device to connect devices to a computer network by using packet switching to receive, process or forward data to the destination device. A network switch is a multiport of Network Bridge which uses hardware to process and forward data. A common type is Ethernet switches that channel incoming data from multiple inputs port to a specific output port to deliver data to the destination device.

Routers, it is a networking device that forwards data packets between computer networks. They perform the direction traffic functions on the internet. A router is connected to two or more data lines from different networks. The most familiar types of routers are small office routers that simply pass IP packets between the computer and internet. (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 12 times more vital than what 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).”

  1. 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 general security arrangement must incorporate an IT infrastructure that describes how an organization ensures its system and data resources. The IT network security arrangement can contain approaches identified with these:

  • User confirmation

  • Permissible programming

  • Remote access

  • Intrusion checking

  • Incident taking(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 acts asa barrier between a trusted network and other untrusted networks. A firewall controls access to the resources of a network using a positive control model. The earliest firewalls functioned as packet filters that inspect the packets which are transferred between computers on the internet. When a packet is passed through a firewall, the resources and destination address along with protocols and destination port are checked against the firewall rule set.

Justification for the proposed network security devices

Secure topologies are frequently established by utilizing a firewall. A firewall protects one system from another malware system. This protection system works mainly on the first three layers of OSI reference model that are physical, data link and network (Swathe, (n.d)).

  1. Computer Systems


Business Requirements

A PC system is a system of interconnected computers which can share a central storage system and multiple peripherals devices such as scanners, routers, and printers. Each computer connected to the system can operate independently while having the ability to communicate with other external devices and computers.

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, including neighborhood (LANs), wide zone frameworks (WANs), framework pieces, intranets, and other data correspondence systems.

PC frameworks hardware and correspondence traditions created through time: the “System Control Protocol (NCP)” progressed to the four layer (1978) TCP/IP tradition stack. TCP/IP got the opportunity to win against the psyche boggling seven layers “Open Systems Interconnection (OSI)” stack proposed (1977) by “Worldwide Standard Organization (ISO),” exorbitantly complex for use and interoperability. A viewpoint of the “Web Engineering Task Force (IETF)” and “Organization of Electrical and Electronic Engineers (IEEE)” traditions stacks (Stewart, 2008).

Fig: Required Computer Systems for the proposed network arrangement

Justification for selected computer systems

Paul Baran proposed a framework system in light of centers that forward datagrams or groups from different customers over a typical line between PC structures from starting to goal. The package trading perspective givesthe quality of framework against framework center point disillusionments, the independent coordinating of datagrams per center makes possible that the datagrams accomplish their goal even inthe region of various center point frustrations.

  1. Network Addresses Design

  2. 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 ofthe 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 of255.255.255.0, 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 thenetworkareto 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 aperennial 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)

  1. “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 theenterprise. 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.
