Network Engineering may be a very broad field and different roles of various engineers won't even by on the point of similar. Network engineers have roles that vary all the means from network support all the thanks to network style and implementation/deployment. I’ve even illustrious thereforeme network engineers that were primarily canonized pc technicians.

It would take a completely unique length answer to really cowl all tasks a network engineer can be accountable for which might not even cover all of it.

As a note, there are getting to be loads of acronyms during this answer so you would possibly need to look some up

To get a decent understanding of what network engineers really do, you'll be able to investigate the OSI model and target layers one through four and also the associated protocols for every layer.

Layer 1 - Physical Layer - This includes local area network with copper and fiber cabling. Wireless signals also are thought-about Layer 1 and infrequently named as PHY. There are a mess of different Layer 1 connections, however those 3 would be the those most worked with in networking. Communications at this layer are raw bits of 0 and 1 s

Layer a pair of - electric circuit Layer - This layer is wherever switches live and play. This layer connects everything at intervals one network and communicates supported mack addresses and frames. VLANs additionally live at this layer to segregate network traffic. Protocols at this layer embody LLDP, VTP, DTP, PPP, and PPTP, to call a few.

Layer three - Network Layer - This layer works with information processing addressing and connects multiple Layer a pair of networks and/or VLANs through completely different routing protocols. Routing protocols include OSPF, EIGRP, and BGP and the Non-routing protocols include IP, ICMP, ARP, HSRP, and VRRP. Again, that list isn't totally inclusive.

Layer four - Transport Layer - This layer provides the suggests that of transferring information from a supply to a destination host. For example, data is get a divorce into packets restricted to the MTU. the most protocols you’d hear regarding at this level are protocol and UDP.

A network engineer may be accountable for any of these layers and typically work with the opposite OSI layers not mentioned. at intervals an equivalent office, one network engineer can be responsible for all layer three activities whereas the person sitting next to him manages the layer a pair of connectivity. In some cases, one engineer might be managing both. It all depends on the specific job and company.

For myself, I’m additional on the implementation/deployment side. therefore I work with installers to deploy new networks at shopper locations. This incorporates a range of factors, to call a few:

Writing config files for instrumentality

Determining and developing VLANs

Ensuring all VLANs are properly trunked between switches

Enable VLANs that require to speak to try and do so, and forestall VLANs from human activity that shouldn’t be

Creating ACLs

Ensuring all connections are operating and every one equipment are properly communicating with every other

Wireless controller configuration

Wireless optimization

I essentially work with all layers, except Layers three and four are limited.

Another thing that Network Engineers do more of now is automation. There are several aspects at intervals network management that may be machine-controlled and it’s the new hot keyword within firms and organizations. I job specifically incorporates that yet to incorporate victimization Python to form scripts for things like config generation, or really managing instrumentality configurations through Netmiko or Ansible.

In the end, if you're searching for a Network Engineer job, pay shut attention to the duty description to envision what that job entails and you’ll need to decide for yourself if you would like to try and do those specific tasks. If not, keep a glance out and a unique engineer job can eventually return up with a very completely different focus.
