Constraints of Network Design

17 Jul 2018

voip-phone, Network Cabling, Data CablingThe constraints of network design are existing factors that cannot be altered, often impacting architecture and functional requirements. These constraints can have a significant effect on network design and must be taken into account. Below are the most familiar design constraints that must be addressed by a network designer.



Cost


Cost is certainly a limiting factor that must always be considered during the design process.



Experienced & Expensive Staff


In order to quickly adapt to new technology, a company may decide to hire technical employees who are expert in the new technologies, but cost more in salary. The greater operational costs for their expertise may exceed the benefits from the decreased TCO (total cost of ownership) derived from the latest technology.



Expertise of Staff


It may be the case that the most efficient, cost-saving design with state-of-the-art technology was presented by the network design team. However, the current staff may not have the experience or know-how to implement this new technology.



Infrastructure Equipment


In cases where an organization has not planned how to replace legacy network devices, the situation can lead to severe limitations on network design. This is quite apparent when new protocols and features cannot be supported.



Location


This is a difficult kind of constraint because location involves limitations that have an indirect effect on design. To illustrate, a rural site might be in a region where fiber infrastructure is not present and wireless is the only connectivity.



Staff Training


Due to the lack of experience of technical staff in a newer technology, issues may take longer to detect and repair until they are adequately trained. This will lead to longer downtimes that render a data center nonfunctional, resulting in business losses.



Time


When choosing an architecture or technology, time becomes a constraint when the time frame plays a part in remaining on schedule for the completion of the project.

Technical & Application Requirements of Network Design – Part 2

30 Jun 2018

As 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?

Technical & Application Requirements of Network Design – Part 1

22 Jun 2018

Cabling, network cablingContemporary network design requires meeting the technical and application requirements of ever expanding and evolving IT and business demands. As time passes, this task is gradually becoming more complex and difficult for both service providers and enterprises. This article will discuss technical and application requirements of network design.



Technical Requirements


A network’s technical requirements can be defined as being the technical aspects that a network infrastructure has to provide in regards to availability, integration, and security. These are typically described as nonfunctional requirements. .


 

As technical requirements vary, they must be used to rationalize a particular selection of technology. Technical requirements are highly dynamic because as technology evolves, so must they. The following are network technical requirements:




  • Increased levels of network availability

  • Integration with network tools and services support

  • Provide for network infrastructure security techniques


Technical requirements assist network designers to be specific regarding technical specifications and the software version that will be able to support them. This sometimes also determines the choice of hardware platform.



Application Requirements


From the business perspective, user experience should receive the highest priority in IT and network design. Depending on the type of business, the term “end users” may vary in definition. Below is a summary of the most common end user categories:




  • Customers/Clients – An individual or a group served by a business. Their level of satisfaction can directly influence the community standing and income of a business.

  • Internal users – The focus is on internal users, who are the staff of an organization. Their productivity impacts business performance efficiency, which has a direct correlation to revenue.

  • Business partners – Represents two or more companies that are cooperating to attain individual or shared objectives. Whether or not they interact efficiently influences their respective success and profitability.


Part 2 will continue discussing Application Requirements.

The Principles of Network Design – Part 4

29 Mar 2018

Office Cabling Network CablingAs discussed in Part 3, a company’s network design should help the organization meet its Business Requirements, give it Business Continuity capability, and provide the adequate Elasticity to allow it to cope with business developments. Part 4 will cover How IT Enables Business Innovation.



How IT Enables Business Innovation


Modern businesses use IT technology to innovate and improve their customer service. When an emerging technology can enable a company to be more competitive in the marketplace and raise customer satisfaction, it will be typically acquired by the business, and its features will be integrated into its network.


A great example of the above is the rapid growth of cloud-based data centers, which are allowing new companies to drastically decrease their capital expenditure and allowing their scaling at will. However, they will still require a high performing data center that has the qualities of flexibility and reliability.



Requirements


A company’s industry and how it began will help a network designer to quickly grasp its underlying requirements. It is obvious banking will certainly need information security. Thus, the network design for banking has to provide the required security capabilities to be adopted by the industry. Moreover, a designer must keep in mind the industry’s standards that are applicable to IT infrastructure and services.



Priorities


Every organization makes priorities that revolve around its business objectives. They should be factored in an IT network infrastructure’s planning and design. Keeping in mind a company’s priorities will help produce a network that successfully supports its business activities.


Suppose an organization’s network for business communication requires (as numbered in importance of priority): 1) collaboration, 2) interactivity, and 3) mobile access. Accordingly, the first two features required must be provided prior to satisfying the third requirement.


In conclusion, a network designer must be cognizant of a company’s business priorities in order to be able to successfully create a network that serves its needs.

The Principles of Network Design – Part 3

24 Mar 2018

Network Cabling, computer,cablingAs discussed in Part 2, Top-Down Logic is used for the process of Preparation, Planning, Design, Implementation, Operation, and Optimization (PPDIOO). In addition, network designers must determine the Scope of Design prior to the collection of data and planning. Part 3 will cover Business Requirements, Continuity, and Elasticity.



Requirements


Figuring out what an organization needs requires having an understanding of its current objectives, mission statement, and future plans. Knowledge of these should guide the business-driven aspects of the network design. Using a top-down approach, a business’s goals, drivers, requirements, continuity, and strategy will determine its business applications, technical and functional requirements, and network infrastructure solutions.



Continuity


Business continuity is a company’s ability to continue doing business after a system outage caused by a man-made or natural disaster that has damaged a data center. An organization needs a disaster recovery plan to develop its resiliency in the face of such disasters. Various parts of its network may need to be more resilient due to regulatory compliance.



Elasticity


Elasticity is an organization’s level of flexibility when responding to business developments. This typically refers to a change in business objectives or conditions, including growth, recession, merger, acquisition, etc. Therefore, a company’s network design must have adequate flexibility in order to fulfill its business requirements and strategic goals. A designer’s comprehension of the overall trends of the organization’s business sector will provide valuable guidance in the design’s features that provide flexibility.


The design of a network must give an organization the flexibility that will allow it to perform integrations with other networks. This will usually be required when mergers and acquisitions take place. It is important to note that during a merger or acquisition, the network may undergo considerable growth during a very brief period. In such circumstances, the most daunting challenge for network designers is having to handle the various design principles, conflicting control plane protocols, and overlaps in IP address spaces of the networks being integrated.

The Principles of Network Design – Part 1

15 Feb 2018

Network Cabling,installationsToday’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.
