Company Overview:
Nettek Systems Consultants, Inc was established in 2000 with the purpose of providing the best IT consulting services possible to our customers. Since establishment we’ve gained more experiences, been 8(a) certified, and most importantly, gained our customer’s trust and respect. Customers who are willing to back up our statement of “providing the best IT consulting services possible.”

Company Capabilities:
With ever improving technologies today, applications are running on more and more complex software and telecommunication environments. Companies and government agencies need employees with diverse backgrounds. Employees who can take on any new telecommunication projects, work on any existing telecommunication projects, and being able resolve any type of telecommunications and applications performance problems encountered in today’s corporate and governmental environment. To accomplish these goals within budget and on time delivery, our engineers are:

  • Capable of utilizing proven Systems Engineering Process to systematically setup, support, and monitoring scalable, robust LAN and WAN
  • Capable of designing, implementing and supporting Enterprise Wireless LAN
  • Capable of designing, implementing and supporting large complex MPLS VPN multi-location WAN/LAN enterprise networks
  • Capable of designing, implementing and supporting VoIP network
  • Capable of setting up and supporting NOC.
  • Beside monitoring the normal up/down status, we monitor with an eye for application performance
  • Knowledgeable in various WAN technologies including ATM, Frame Relay, Metro Ethernet, and MPLS
  • Knowledgeable of various features of Cisco IOS/Cat OS software including IPSec, WAAS and QoS just to name a few.
  • Knowledgeable in various network management tools including TACACS, CiscoWorks, Concord Performance Manager, various Opnet suite of tools (IT Guru/Panorama/LoadScaler/NetDoctor) and nGenius just to name a view
  • Being able to get understanding of customer’s existing network and politics thus able to provide/assist new network migration in the most optimum path for customer. For TNET, this is a valuable asset.

Systems Engineering Process:
Systems Engineering Process is a proven method used primarily in the manufacturing industry to bring a product from a conceptual idea to the shelf for the consumers. It is an effective, economical application of scientific and engineering efforts to transform operational needs into a defined system configuration through the top-down iterative process of requirements definition, functional analysis and allocation, synthesis, tradeoffs and optimization, design, test and evaluation. By adapting this process into our telecommunication design and operation, we are able to bring conceptual idea into reality on time and within budget.

About Nettek’s President
Tan Nguyen graduated from Virginia Tech in 1995 with a BS in Electrical Engineering. While interning at TRW (now known as Northrop Grumman) during his last years of college, he was exposed to the System Engineering Process. Realizing the importance of this process, he got his MS degree in Systems Engineering in 2000, also from Virginia Tech. This education served him well while he was working at Hughes (now known as Raytheon). With this education and experiences in telecommunication, he is able to adapt the systems engineering process to telecommunication projects.

We pride ourselves in understanding the basics of telecommunication, its technologies, and the software programming required to support corporate and governmental agencies daily challenges. From these basic understandings and comprehension of the systems engineering process, we are able to build, maintain, and resolve complex WAN, LAN, and application issues ranging from application performance problems to cabling problems.

Nettek’s 8 Layers of the OSI Model TM:
In order for small businesses to be successful in today’s complex business environment, we must not only understand the basics of the 7 Layers of the OSI model to help us resolve complex problems, we must also understand the 8th layer.

This 8th layer collects all types of information from customer’s existing capabilities, hardware, software, personnel resources and identifies the directions the customers heading towards. (i.e. customers’ existing environment). Understanding the customer’s existing environment  improves the product and services we provide at a competitive cost. Your employees can be one of the best technical employees, but not having someone who understands Nettek’s 8th layer of the OSI can cost your corporation or agencies additional expenses and delays

Layer 8: Customers Environment and Requirements (Flexibilities and constraints)
Layer 7: Application
Layer 6: Presentation
Layer 5: Session
Layer 4: Transport
Layer 3: Network
Layer 2: Data Link
Layer 1: Physical
