Technical & Application Requirements of Network Design – Part 2

30 Jun 2018

Office Cabling Network CablingAs discussed in Part 1, contemporary network design requires meeting the technical and application requirements of ever expanding and evolving IT and business demands.


Part 2 will continue discussing Application Requirements.



Importance of User Expectation


Networks or IT technologies that are unable to achieve a satisfactory level user expectation or QoE (quality of experience) will be considered to have failed meeting an important business goal. As a result, they will be considered a cost, rather than tools that allow a business to succeed.


A network’s design must take into account how a satisfactory level of user experience will be attained. From the point of view of a user, QoE when utilizing services and applications will determine their level of satisfaction.


The deployment of services and applications before taking into account their features and network requirements will result in a failure to achieve business goals.


To illustrate, a financial services company that wants to provide a video communication application to their customer service representatives, but fails to secure enough bandwidth, will likely frustrate their reps and displease their customers when calls are dropped or interrupted because of excessive latency. Thus, their corporate goal of differentiating themselves from their competitors will be a failure until they meet the network requirements of the application.



Evaluation of Application Requirements


Network designers should keep in mind their responses to the key questions below for the evaluation of application requirements:

  • What are the application’s features and characteristics?

  • What is the length of time the application needs to reset its session or state after losing connectivity?

  • What is the amount of network traffic that is required by the application?

  • How important is the application to the organization and what is the service level it will require to function properly?

  • For its compliance with industry regulations and company security polices, will the application have separation requirements?

The Principles of Network Design – Part 1

15 Feb 2018

Network Cabling,Installations Washington D.C.Today’s network design must be capable of providing the technical requirements of expanding and evolving IT and business demands. As a result, the task is growing in complexity and difficulty for both service providers and enterprises. The challenge is even steeper when dealing with a legacy infrastructure that must be upgraded for the adoption of newer technologies. In order to succeed, a network design may use either of the two structured approaches discussed below.



Top Down


As it simplifies the process, the top-down design approach is favored by many designers. It does so by providing more control by dividing tasks to directly aim at the scope of the design, assisting designers by letting them view solutions from the perspective of the enterprise.



Bottom Up


On the other hand, the bottom-up design approach initially chooses network technologies and design models. Unfortunately, this greatly increases the risk of design failures due to the greater possibility the network will not be able to provide the needs of the application or business.



Business Driven


An emphasis on a business-driven approach will greatly improve the prospect of attaining a strategic design that will be a success for an enterprise. This is achieved by making both business and technical objectives the central focus of network design. The following will illustrate how a Business Requirement will guide a respective IT & Network Strategy as laid out by the bullet points below:


Business Requirement                   IT & Network Strategy

  • Cost Efficiency                                       Consolidate and virtualize networks.

  • Flexibility                                                Make design responsive and adaptable.

  • Industry Compliance                            Ensure compliance with industry standards.

  • Continuity of Business                         Design resilient services and networks.

  • Access Control                                       Maintain confidentiality throughout network.


Compliance


Enterprises commonly practice strict compliance with industry standards to secure advantages for their businesses. For example, compliance with ISO/IEC 27001 Information Security Management raises the reputation of a financial services company by reducing the number of security breaches. In addition, its operational costs from downtime are minimized.


Part 2 will cover the topics of Top-Down Logic and Scope of Design.
