The Open System Interconnect (OSI) model is a set of layers that provide the levels in which the information (or Network packets) takes different forms while travelling from one host to another host.
The OSI model has the following layers,
- Application Layer
- Presentation Layer
- Session Layer
- Transport Layer
- Network Layer
- Data Link Layer
- Physical Layer
Most of the time knowledge of these seven layers is taken to trouble shoot a network.
There are many jobs that require the knowledge of the OSI model. One of those jobs is the job of a Network Engineer that use the OSI model to trouble shoot the Network. In the following it’s a Network Engineer job description that requires the knowledge of OSI model.
- A Network Engineer that can provide technical support in the performance and conservation of the production network.
- Plans, designs, troubleshoot and rectify problems in order to alleviate and enhance the network, meeting the customer requirements for both software and hardware.
- Provide Configuration and integration of different Hosts and provide solutions for new and live customer networks.
- Follows established procedures to guarantee the quality of new software and hardware does not adversely affect our customers, execute feature/new product examining and software/hardware support for major systems with no direct supervision.
After the Network Engineer obtains a job, he is provided orientation of the company and in some cases he is provided with training also even if he is experience. The manager and collogues work hard so that the new comer jells in with the IT department staff and provides his useful services to the company. He is also granted access to computer and other network devices by the network administrator. He also provided a laptop to help him connect with the network devices and after that he starts to work as a network engineer of the company. If the company provides outsourcing services to other companies and the network he is bound to work are not present in his workplace then the network engineer is supposed to work with virtual network software to practice design and troubleshoot the virtual networks.
Skills Required for Network Engineer
- Analytical Skills: Network engineers have to be able to look at complex network systems and digital machines to find faults and problems and devise ways to remove them. They need to find room for improvement and optimize the efficiency of a network.
- Attention to Detail: Network engineers need to produce complex designs for communication networks, and need to confirm that the network systems will function efficiently.
- Leadership Skills: Network engineers can be become leaders of other engineers to design, create or operate the network. It requires good experience to obtain leadership.
- Organizational Skills: In many business developments like mergers and acquisitions two or more different networks come together as companies combine. In such a situation operating the new network can become a very demanding challenge.
- Teamwork: Larger firms have several employees and engineers working together. It is important for a network engineer to be a team player.
Qualifications for the job
- Network Engineer must have thorough knowhow of IP routing, BGP, switching, routing and the OSI model.
- The candidate need to have experience with Cisco and Juniper firewalls, routers and switches.
- Have an active Cisco Certifications or the equivalent years of experience and has demonstrated skills. (Careerbuilder.com, 2014)
