A telecommunications network engineer is an expert designer, who knows how to install maintain the computer networks and telecommunications. He need not play a technical role; he must have the understanding about the business processes and know that designs offered are suitable for the procedures of a business. The network infrastructure should facilitate the business and help in reaching the goals and productivity for a long time. If the network infrastructure is beneath the expectations then it will bring the business to halt.
Network Engineers generally hold an engineering or technical degree in Telecommunications or Computer Sciences. In addition to or as an alternative to, some Network Engineers would have started on an apprenticeship scheme and may be manufacturer certified such as Cisco, Juniper, HP or other related companies. In recent years, generic training packages have taken on more relevance to the practical aspects of Network Engineering. The Building Industry Consultancy Services International (BICSI) introduced several training specialties with formal training courses, exams and 'on the job' training and development. These are very good programmes, lending themselves to older students looking to change their career.
To design the network and to trouble shoot the seven layer architecture, the network engineers use the open systems interconnection as a tool, which is a very helpful tool in the education process of the network engineers. The communication between the two devices will be divided in to seven layers from this architecture. To give an example, the physical layer which is the bottom layer in the architecture. It includes the connectors and the cables or may be air for wireless connections as well. This layer is required to connect any two devices physically. The data link layer is the second layer which will safely transfer the data across the physical layer. The third layer is the Network layer, which will establish, maintains and clears down the connection across the network. The most important protocol which is used in the Network layer is IP (Internet Protocol).
The other layers of the architecture are transport layer (TCP - Transport Layer Protocol), the fifth layer is the session layer. Sixth is the Presentation Layer and the last is the Application Layer. It is important to understand the complete seven layer architecture, and the emphasize should be from one to four. A good Network Engineer should be able to efficiently and effectively run and terminate copper or optical fiber cables, or wireless links and configure the like and routing Protocols. They should have good knowledge about the network security and should be clever enough to ensure that the customer's data and telecommunication links are safe from the hackers and virus and malware attacks.
A Network Engineer's typically originate from structure cable installers, Network Administrators and ex military personnel (through repatriation training). The Network Engineer may progress on to specialize as a Network Architect, Wireless specialist or Security expert. Salary depends upon his/her level of experience but on an average he/she is paid between $50,000/- to $80,000/-. Good Network Engineers can travel the world as they are in great demand, especially when required to troubleshoot serious problems or redesign failing networks while the business is operational - often a very risky and complex task.
