Networking in IT infrastructure

Discuss About The Happy Haven Day Care Network Design Proposal.

Networking in IT infrastructure that act of connecting the devices with a purpose to enable resource sharing this may include the data, printers and other many more (Mitchell, 2017). Many network in computers may be with designs and this always depend on the size of the organization and what need to be implemented (JoshWepman, 2015). This proposal is for provision of network design that should be adapted by the given company where we have to apply both the cloud-based and dedicated server techniques.

The main aim is to achieve the various objectives that will the help an organization in conducting its service a more effective and much more efficiently (Coleman, 2012). The idea here will help in achieving both the operational and business objectives. The following objectives shall need to be followed and they are vital in the network to be laid.

• Scalability- This is the idea where the network design to be set up to have the capabilities of accommodating more devices when need arise in future. The design should allow expansion or extensibility in future without necessary having to draw another design from scratch.
• Secured Organization Services- This network should enhance a more secure environment for its operations.
• Info processing being effective- The aim of network design is to ensure that all users are able to retrieve. Processing and storing of info related to the organization operational services in a more effective and very transparent manner.

There are many components that makes the IT infrastructure and helping in facilitating in designing a good network design that is needed by different firms. In the case here some of the components are discussed here below.

1. Switch

This is a hardware device used for connecting the devices over the network within a single LAN (Mitchell, 2017). They may come with various versions depending on the size of the network and how scalable the network is. The figure below shows some of the versions of switches.

Figure 1 Switches

1. Routers

This are devices that are used for connecting the network to the internet. They offer the provision of all the devices that are embedded on the accelerating encryptions, expansion slots for DSP, firewall, intrusion preventions, processing calls, services applications  and voice calls.

1. Wireless Access Point (WAP)

This a device in networking used for creating the wireless LAN which is WLAN. The device is known for using transceiver that broadcasts Wi-Fi signals within the organization and hence allowing more users to connect to the LAN.

1. Fiber Cable
2. This type of component serves as a transmission media that connects the devices to the network,
3. Server and the storage components

Components used for managing the access to all resources shared and services in a given network. This servers may include the DNS server, Web Server, File-Server and the database server.

1. Workstation devices

This includes devices like computers, Iphones etc. that are connected to the network.

1. Cat 6 Ethernet cable.

This are the cables used for providing the connection of the access layer devices to the network organization.

1. Operating system components.

This includes the Operating system of the work stations and the servers and not forgetting the Network operating System (NOS).

Components of IT infrastructure

 All of the above discussed IT infrastructure components are very essential to enhance a network design that is of good quality for any organization, and in order for us to achieve the stated objectives the following components will have to be used. The network designs having to rely with the discussed above components will make it to be successful (Mbaocha, 2012).

This hierarchical networking design is specifically the situation where the flat switched network is broken in to three layers where each layer in the model performs specific functions leading to simplification of the network thus making it easy to scaling and managing the network (CISCO, 2014). The 3 layers of this design are explained here below.

Access layer- the layer offers provision directing the end-user who connect to the LAN

Distribution Layer- this layers used for connecting the components of access layer and also enabling the access layers connectivity to services (Technet, 2015).

Core Layer – helps in connecting DL to large LAN organizations.

Current IT infrastructure Analysis in The organization

The situation of the current network in the organization is that it poorly designed. The use of the Flat switched network design in the organization has made it hard in managing the design as well as conducting the operations in an effective manner when we consider the size of the organization. The other idea is that the network in place is not scalable (Cisco, Benefits of a Hierarchical Network, 2009). This means incase the network needs to be expanded we will have to draw another design from scratch. There will be a lot of problems which are complex when troubleshooting. Another problem is the network being insecure hence in case it affects the company everything is paralyzed.

The proposed future network design of the organization is based on a three-layered hierarchical design. The design is highlighting each and every component in each layer in the design (Adato, 2015). The three layer is used for simplifying the whole company network design by making it flexible, scalable and much more easy to managing and troubleshooting hence improving the processing speed (Cisco, Small Enterprise Design Profile Reference Guide, 2013). The diagram below illustrates the above

The geographical scope would be the many as to many as we consider the network to extend to more than one building hence enabling the connectivity between the given number of LANs (requirement, 2014). The geographical requirement in the three hierarchical layers will be as follows.

Current IT infrastructure Analysis in The organization

In this layer there is provision of the interface with the end-users such as PCs, printers that will help in enabling the access to entire network. The main idea is ensuring that connections of the devices in the network to the network and controlling the communication modes as located on each network (CISCO, 2014)

The purpose of this layer known as distribution provides an interface in between the components of both the access layer and of the core layer in the specific network. The network access functions, the intelligent routing and the switching occurs in this layer for the entire network. This will ensure that there is high availability of the core in accessing the layer of the end user gadgets.

This layer includes routers used for acting like a central hub enabling the functions of the network to access the internal and external networks respectively.  it is known for bringing together all the distribution layer switching from all organizations, this layer make it easy as it is scalable, flexible, reliable and much more its high speed in providing the connectivity. The diagram below shows how the core layer functions.

If each module of the design of the network is enabled in replicating the various components of the network as the network expands it make it possible in conducting an expansion in planning and implementation to be easier than it is in the current situation. This is sometimes done by adding more distribution layers switches so that they can accommodate more access layers and end users (Guide, 2011) .

Dedicated server is a central PC used for storing info and allowing one to share and access the info to various devices in the network (Hope, 2017). Some of this stated servers are such as the.

File Server- used for managing the storage and data files transfer across the whole network of the organization (Rouse, 2009). 

Mail-server- is an application server used for managing the incoming mails from all devices in the network domain. The server is used in forwarding the emails when delivered to their intended destinations. It used for managing all emails communications within the company.

Web-Server- its purpose is using the http in providing services to the users who requested the webpage a file.

DNS Server- a server that match all the corresponding domain names with their IP addresses associates within the company network and they are offered by the internet service providers. It normally processes by requesting from the devices and locating the response using the IP address.

Proposed Future Network Design of the organization

Dynamic Host Configuration Server. (DHCP)

A network server that is used for generating and automatically assigning the IP addresses and the defaults gateways to the end users devices that are connected to the company network.

The logical design for all dedicated servers will be represented in the diagram below. From the diagram below the data center is used for hosting all the dedicated servers on the proposed network design of the given company. All the request from the networking devices are processed at the data center where all the servers are located. The dedicated server  network design below shows three layer hierarchical design of the anticipated network for the company.

Considering we have more that 1000 computers in the organization which are distributed the given buildings which are adjacent to each other. With the given info above then it will be appropriate in allocating the IP addresses to all available workstations and hence able to give allowances for scalability in future. Assuming each building has about 500 workstations therefore we will have to apply Class B of IP address for the proposed network design of the Company (Subnetting, 2010). The figure illustrates the Ip addressing details.

The given IP addressing details are scalable in the manner that in case any new person or device connected to the organization can be accommodated and hence achieving the objective of scalability.

There are many organization that offers the networking services to organizations. Instead of a company using the physical dedicated servers it may seek services from cloud organizations institutions like explained here below.

MS is known for offering provision of services such as the storage services, management of data, messaging and the CDN. Based on the organization needs there are various servers located in the cloud acting as the data center for the company. The organization can host its servers (mail-servers, data management and the storage databases) using the MS Azure. The provider here is very reliable and scalable and he is controlled by the MS Azure Fabrics by ensuring the services and the Infrastructure that is laid do not crash and hence able to make it more reliable (Macken, 2016).

Another cloud service is the VMware which offers the provision of services such as the storage, advanced networking, and the integration of the enterprise environments and services such as the data recovery. This VMware has a very advanced security measures which ranges from the security of the private networks to the compliance certificates they hold. This VMware also offer provision for enterprise platforms in IT for the reconstruction of the data centers which has enabled many organizations in addressing their needs without necessary changing all the already implanted processes (cloud-services, 2017).

Conclusions

From the above it has been clearly seen that the organization will need a network design that would be easier in managing and most of it all scalable than the existing system (Meena, 2017). The recommendations in this scenario will be that the organization to adapt to a new proposed design of the network which is simply the three-layered hierarchical architecture which is clearly defining and addressing the problem by making it easier in knowing which part of the network is performing which operations.
