Core Responsibilities of Network Engineers

Discuss about the Developing Competencies for Existing Networking Skills.

As we know that network engineers are positioned at the core of the network foundation, they must be able to deeply understand the network infrastructure as well as the applications running on them. Network is considered as the nucleus of the entire technologies that has the ability to combine all applications, the network engineer must integrate these applications together. Having advances such as automation of entire system and SDN, systems of today are custom-made around the entire applications that are running crosswise over them. Accordingly, engineers must have the capacity to comprehend application need, understanding network traffic, and other arrangement to streamline information transport. (Froehlich, A., 2017).

System designers can work internally or externally depending on the requirement and size of the organization. They will likely guarantee the uprightness of high accessibility networking environment to give most extreme execution to their clients. Users might be staff, customers, clients and providers. Networking engineer is the main person who is responsible for installation, analysis, engineering as well as execution of new frameworks and advances like Software Defined Networking; setting and keeping up global system specialized benchmarks; give improved framework abilities and development; give consultation to tasks and system organization. (Performance recruitment inc., 2017).

Being a network engineer in IT department in Education sector, my job duties include responsibilities such as planning, installation, maintenance, investigating troubleshooting or test systems. I am responsible to configure as well as installation of hardware networking devices like switches, routers, firewalls and VPN QoS. I am also responsible to perform network support as well as any network updates that includes service packs, patches, hot fixes or any other security configuration. By utilizing Command Line Interface (CLIs), I use to configure layer 3 routers, switches etc. I evacuate or install information outlet which incorporates testing and fixing Ethernet links and repairing any data ports. By using GUI application to provision, I use to install, configure or analyze any remote access points. (https://resources.workable.com, 2017).

The modern organization's enterprise information and communication technology (ICT) must needs some adaptable, varying bandwidth alternatives. The demand of enhanced bandwidth is expanding exponentially over different networking techniques going from private multiprotocol switching (MPLS) systems to public or private wireless network. It requires another innovation design that can give agile as well as ensured execution relying upon the particular applications which is being used. The implementation of secure, hybrid networking device for secure, hybrid IT organizing is a communication service provider (CSP) which is virtual private system (VPN) which is capable for delivering good quality voice, video, as well as business information applications to the scope of business areas. My main aim is to develop the following competencies so that I can be a better asset for the organization: (Munroe, 2017).

Developing Networking Competencies

Configuring Virtual Profile for Virtual Network – In order to minimize the installation cost of networking, we can use virtual networking in the organization. As virtual networking is the main area of interest for today’s networking. The high speed routing as well as packet forwarding and in addition encryption whether it is IPsec or SSL and balance traffic load, it all depends on the dedicated silicon. For all these activities, a dedicated hardware must be required that leads to increase in the networking expenses. Therefore, these days virtual networking is in trend.

Virtualized networking is used when firewall as well as other routing functions that are actualized as a component of the virtual switch in every hypervisor. This could bring about ideal traffic flow between virtual machines whether they have a place with a similar IP subnet or not and take care of the issue of network traffic. (Pepelnjak, I., 2017). It is very flexible in terms of increasing number of users for future. No extra cabling expenses needs to bear by the organization. It is the secure way for communicating with its remote staff.

This type of networking will help to increase the productivity of the organization. The other staff of the organization in this working environment have a tendency to dedicate less time and vitality to ordinary office schedules and more to clients. The option working environment additionally can give organizations an edge in competing for—and keeping—skilled, profoundly energetic representatives. (Apgar, M., 1998).

Configuring VOIP Devices - Viable communication helps the organization for performing work very effectively on time and within specified budget.  Administrators as well as group pioneers who can impart, and relay targets, ideas and particular tasks in a succinct and lucid way, utilizing the correct options. It helps to contribute to the business in a positive way. Organizations utilize intranets, applications, messages and video calls to speak with workers crosswise over offices and areas. Business intranets have additionally turned into the standard in overseeing information including rules, methods, conventions, corporate reports, marking, logos as well as different assets. Innovations like VoIP (Voice over IP) are decreasing the requirement for customary telephones while WebRTC (Web Real Time Communications) empowers video conferencing from better places far and wide utilizing standard programs and applications. (Elcom, 2016).

By implementing VOIP in the organization, the staff would be able to work in a quiet library or can connect with other members of the team. VOIP devices will help the staff to easily move between desk and other room and can easily make the call if they are not on the desk. It will help to increase the mobility of staff and hence the organization can work in more efficient way. The essential purpose behind this change is the lessening of operational cost where VOIP innovation has progressed and can support voice over the network. I'll get into the system as well as hardware segments required to set this framework up, with the networking design. (Aruba Networks, n.d).

Configuring Virtual Profile for Virtual Network

Configuring New Switches - The most ideal approach to get more execution from the client's system is by enhancing LAN execution. That will be taken care of by great design including things like 100-Megabit or Gigagbit Ethernet switches with Layer 3 and VLAN abilities. Those center system tools are creating advances that will be vital for developing better network infrastructure like VoIP that place more requests on systems. The other quality of network is its reliability.  As our customer utilizes multimedia devices like mobiles, IM and Video etc. It's essential that they have a dependable Internet association and an advanced switch. The quality of service with voice and video will turn out to be imperative. (Vlasach, M., 2008).

In order to enhance new competencies in configuring a network, I will choose which security convention to run with. SSL/TLS, IPSec, PPTP, and L2TP are the absolute VPN protocols, with SSL and IPSec demonstrating most prominent with corporate clients. Adaptability is another central point to consider when setting up the VPN. The devices in Layer 2 must be in a flat system with minimum control broadcasts or to filter the undesirable network traffic. Data about the present network and administrations is assembled and must be analyzed. It is important to look at the usefulness of the current system with the characterized objectives of the new task.

Utilizing VLANs and IP subnets is the most widely recognized technique for isolating user groups as well as the network traffic in the access layer network. Ordering information at or close to the source empowers the information to be assigning the priority when movement is all along the network traffic. Isolating traffic with comparative qualities into classes, and after that denoting that movement, is a capacity of the devices at the distribution layers. A case of this system is to put the voice activity on an access switch into a solitary VLAN. The devices at that point denotes the movement beginning from the voice VLAN with the most astounding need. (https://www.scte.org/, n.d).

Adding VOIP to the network can be a critical extra load for the entire network. I have to ensure it can deal with the extra traffic easily, with no discernable delay during making calls. Also, IP calls signals must be clear and strong enough for the calls put on the PSTN. By deploying IP PBX framework or adding a voice protocol to the system is challenging; it influences the whole system, from ability to execution. So, I would like to work with my seniors so that I can get the right solution. (Sampson, P., 2011).

Conclusions

Configuring VPN as well as its operations are presently business-based. Profound abilities, demonstrated techniques and powerful procedures are vital to satisfying organization particular objectives at moderate cost – and for making a future-confirmation, the agile solution that can adjust to evolving needs. A prime illustration is Managed VPN Services. This solution grants outstanding economies of networking expenses for the entire network while delivering an enduring change in quality ensured by the supplier's operational magnificence.
