What are the other designations of a NE ?
- support engineer;IT support engineer;helpdesk support;network administrator;security engineer;network architect;VoIP engineer;Cisco engineer;systems engineer;systems support engineer.
The work is influenced by the size and sector of the employing organisation.
In a large investment bank for example, a network engineer may have specific responsibility for one area of the system. In a small company, the engineer may be trouble-shooter for almost any IT-related problem that arises.
Tasks usually include:
- establishing networking environment by designing system configuration, directing system installation, defining, documenting, and enforcing system standards;
- the design and implementation of new solutions and improving resilience of the current environment;
- maximizing network performance by monitoring performance, troubleshooting network problems and outages, scheduling upgrades and collaborating with network architects on network optimisation;
- undertaking data network fault investigations in local and wide area environments, using information from multiple sources;
- securing network system by establishing and enforcing policies, and defining and monitoring access;
- the support and administration of firewall environments in line with IT security policy;
- updating job knowledge by participating in educational opportunities, reading professional publications, maintaining personal networks and participating in professional organisations;
- reporting network operational status by gathering, prioritising information and managing projects;
- upgrading data network equipment to latest stable firmware releases;
- configuration of routing and switching equipment;
- configuration of hosted IP voice services;
- basic configuration of firewalls;
- remote support of on-site engineers and end users/customers during installation;
- remote troubleshooting and fault finding if issues occur upon initial installation;
- capacity management and audit of IP addressing and hosted devices within data centres;
- liaising with project management team, 3rd line engineers and service desk engineers on a regular basis;
- speaking with customers via email and phone for initial requirement capture.
Types of network
There are different types of network, such as:
- LANs – local area networks, linking a limited area such as a home, office or small group of buildings;
- MANs – metropolitan area networks, linking a large area such as a campus or city;
- WANs – wide area networks, which link nationally or internationally;
- WLAN – wireless local area network;
- GANs – global area networks, combining all of the above with satellite mobile-communication technologies;
- SAN – storage/system/server/small area network;
- CAN – campus/controller/cluster area network;
- PAN – personal area network;
- DAN – desk area network;
- VoIP – voice over internet protocol network.
Salary depends on the size, type and sector of the organisation you work for, and the size and scope of its computer and network installations. Our Past students are earning Rs. 5 lakhs per Month.
Other factors that contribute to salary include the value of the IT infrastructure, so network engineers in the City of London, for example, can be paid considerably more.

Relevant work experience is beneficial, including experience gained through vacation work and summer placements, and being on the user end of IT systems is useful, too, as it gives you an idea of the types of problem that arise. Experience of team-working is also important.
Network engineers can find work in any organisation with large, sophisticated IT systems. Examples of typical employers are:
- banks;building societies;retail groups;large government departments;schools;hospitals;
utility companies;local authorities;transport providers;management consultancies.
Some organisations, including many local authorities and other public sector bodies, now outsource all their IT systems to specialists, so these specialist companies often have vacancies for people with networking skills.Network engineers can be employed by a large IT company to manage the firm’s own systems or work in their contract services.
Large companies, such as Microsoft, provide an extensive range of installation and customer support services and they recruit graduates and experienced staff into all areas of IT support.There are also many small consultancies that work by setting up and managing systems for organisations that are too small to warrant full-time IT support.
Look for job vacancies at:
- News Papers;Computer Magazines;Naukri.com; monster.com; LinkedIn.com; Careers service vacancy lists ;National and local press;at Our Placement Cell
There are many recruitment agencies specialising in IT careers. These are usually more useful once you have built up some solid work experience.
While large companies usually have a structured graduate recruitment procedure, you should approach small businesses and IT consultancies on a speculative basis, ensuring your CV stresses your personal, as well as technical abilities.
With more emphasis being placed on experience, recruiters increasingly demand evidence from candidates of skills developed through project work and placements.
There is currently a shortage of network engineers in India.
Whatever knowledge you already have when you enter this field you can be sure that, in this rapidly changing industry with its many and frequent advances, you will need to make training a constant part of your career development.
However you’ll often find you need to seek out appropriate training for yourself, especially if you’re seeking promotion, a career move or are self-employed.
Relevant qualifications include:
- Cisco Certified Networking Professional (CCNP) and/or Cisco Certified Networking Associate (CCNA)
- Microsoft Certified Systems Engineer (MCSE) – covering network analysis, design and implementation;
- Microsoft Certified Systems Administrator (MCSA) – covering network implementation, management and maintenance;
- Redhat certified System Engineer
Courses may be expensive and you may have to pay the fees yourself, you treat this Fees as an investment for your Career in Network Engineering.
Your career path will depend, to a certain extent, on the size of the organisation you work for and the scope of its IT systems.
Having gained experience, network engineers can progress to network management positions or, with additional training, transfer into other IT roles, such as project management.
Those who start as help-desk technicians can sometimes progress to network engineer posts, then on to senior network support and finally network controller (mainly involved in decision-making, staff management and advice on future strategy). This may be a typical career ladder in an organisation such as a large bank or a major government department.
If you work for a small company, you may be the network controller from day one and also have many other IT and technical support-related responsibilities. Every Schools,Colleges, Hotels,Banks, Shops etc need Network Engineers.
Network engineering and network support roles tend to move you away from programming, so if this is something you enjoy and want to keep up, you need to be aware of this before you commit yourself to a systems support role.
Another alternative could be working as an employed network engineer for five to ten years then moving into IT contracting and self-employment.Some network engineers choose to broaden their careers into other IT, customer-related or management functions. Technical or infrastructure project management and network architecture are possibilities.
We can segregate the Networking World into LAN, WAN and Security.
LAN Network is the study of Windows 2012 Server and Windows 8 Client( Course : MCSE ) and Redhat Linux (Course : RHCE) . For studing WAN, we study Routing and Switching( Courses : CCNA and CCNP),Voice( Courses : CCNA Voice, CCNP Voice) etc . For Security side, we need to learn to implement security over the network (Courses : CCNA and CCNP Security ,CISSP and CEH)
Exchange Server is the mail server product of Microsoft. If you have good understanding of Windows Server (MCSE Course), you can follow Exchange Server. This Course is very much needed for Enterprise level business environment.
Sharepoint Server is the document management Server product of Microsoft. In order to learn Sharepoint Administration you need to have good understanding of Windows Networking concepts.
Anyone who has basic understanding of Networking Concepts , can go for Cisco courses. It consists of three tracks.
1. Routing and Switching : CCNA -> CCNP -> CCIE (R&S)
2. Voice : CCNA -> CCNA Voice -> CCNP Voice -> CCIE (Voice)
3. Security: CCNA -> CCNA Security -> CCNP Security-> CCIE (Security)
CISSP courses are required for those who are in Networking Consultancy and Auditing and also who administers wide networks. This course requires good knowledge of Networking Concepts.
CEH is the recommended course for those who want to secure their network from Hackers and intruders. The course enables you to secure the network by employing a number of tools and injecting different kinds of malwares and viruses into our own network and to find the loopholes in the network.
Now a days lot of companies uses Linux Servers along with Windows Servers. In big companies , you can find different applications running on different servers and some applications are not compatible with a particular server. Some companies develop applications and databases based on Linux Servers to save cost and stability. For administering these networks, we need RHCE professionals.
CCIE is the most wanted Certification in the world because few professionals have achieved the prestigious CCIE certification (presently nearly 40,000 in the world). CCIE certified professionals are in high demand and that are paid very highly. Banks, Telecom,Fortune companies need CCIEs for their network administration. CCIEs design,plan, configure and administer the networks.
Presently , there is no minimum qualification requirement for any of these certifications. Anybody having the interest in Networking field can go for the certification . Companies which recruits the Candidates may fix the minimum qualification like Diploma,Graduation,etc. based on their standards.
