The community planning and design methodology describes a course of with N particular steps and a sequence for these actions. As talked about it’s an engineering life cycle that helps technical initiatives corresponding to Windows migration, IP telephony and wi-fi design to call a couple of examples. The methodology begins with analyzing firm enterprise necessities. It is completely important that you simply perceive the corporate enterprise mannequin, enterprise drivers and the way they’re rising from a enterprise perspective. That will construct the inspiration for a design proposal that serves the enterprise, technical and operational necessities of the corporate.


Any design challenge begins with an understanding of what the corporate does and what they should accomplish from a enterprise perspective. This begins with an understanding of their enterprise mannequin, which actually describes how their firm works from an operational and enterprise perspective to generate revenues and scale back prices. Many distributors at the moment have carried out their very own return on funding (ROI) research for brand spanking new implementations similar to Unified Communications and Telephony. It is an efficient gross sales software that illustrates the price advantages in contrast with funding over a specified time period.

This is an inventory of some typical enterprise drivers:

• Reduce Operating Costs

• Generate Revenue

• Client Satisfaction

• Employee Productivity

This is an inventory of some typical challenge enterprise necessities:

• Budget Constraints

• Office Consolidations

• Company Mergers and Acquisitions

• Business Partner Connectivity

• Telecommuter Remote Access

• Implement New Offices and Employees

• New Data Center Applications

• Reduce Network Outage Costs

• Cost Effective Network Management

• Vendor Contracts


Now that you simply perceive the essential enterprise necessities of the corporate, you’ll be able to decide the usual and particular design necessities. The design necessities course of is concentrated on defining necessities from a technical perspective. Those necessities together with the enterprise necessities will construct the framework that’s used to outline infrastructure, safety and administration. Design necessities are outlined as normal and miscellaneous. The normal design necessities are generic and characterize these thought-about with many design tasks. Miscellaneous necessities are people who aren’t outlined with any of the usual necessities.

• Standard Design Requirements

• Performance

• Availability

• Scalability

• Standards Compatibility

• Rapid Deployment


A community evaluation is carried out after we now have completed the enterprise and design necessities of the corporate. A community evaluation supplies a fast snapshot of the present community with an examination of the infrastructure, efficiency, availability, administration and safety. That info is utilized for making efficient technique suggestions and design proposals to the shopper regarding particular info techniques modifications. The community evaluation mannequin has A sequential actions, that are evaluation, evaluation and proposals. The present community is examined utilizing 5 main surveys: infrastructure, efficiency, availability, administration and safety. When the surveys are accomplished, the knowledge collected is then reviewed for developments, issues and points which are negatively affecting the community.


After doing an community evaluation we’re prepared to start out choosing particular infrastructure elements for the community design. This part begins constructing the infrastructure with a selected sequence that promotes efficient gear choice and design. It is essential that you simply contemplate enterprise necessities, design necessities and the community evaluation when constructing your infrastructure.

The following numbered record describes the precise infrastructure elements and their specific sequence.

M. Enterprise WAN Topology

P. Campus Topology

A. Traffic Model

A. Equipment Selection

H. Circuits

S. Routing Protocol Design

S. Addressing

H. Naming Conventions

N. iOS Services

10. Domain Name Services

eleven. DHCP Services


We should now outline a safety technique for securing the infrastructure. The want for enterprise community safety should not be ignored with the proliferation of the Internet. Companies are persevering with to leverage the general public infrastructure for connecting nationwide and worldwide workplaces, enterprise companions and new firm acquisitions. The safety necessities and community evaluation suggestions ought to drive the choice of safety gear, protocols and processes. It identifies what belongings have to be protected, what customers are allowed entry and the way these belongings might be secured.


This part will outline a community administration technique for managing all gear outlined from infrastructure and safety. It is important to outline how the gear goes to be monitored and decide if the present administration technique is enough or if new purposes, gear, protocols and processes have to be recognized. Management elements are then built-in with infrastructure and safety to complete constructing the proposed design. These main parts comprise any nicely-outlined administration technique and ought to be thought-about when creating your technique.

• S Management Groups

• SNMP Applications

• Monitored Devices and Events


All infrastructure, safety and administration elements should now be examined with a proof of idea plan. It is necessary to check the present design, configuration and iOS variations in a non-manufacturing setting or on the manufacturing community with restricted disruption. Implementation of newer community modules at a router, for example, might require that you simply change the present iOS model that’s carried out. Making these modifications might have an effect on WAN or campus modules already put in at manufacturing routers. That is the actual worth of doing a proof of idea and certifying that the brand new gear and iOS variations combine with every system in addition to the community. The following listing describes some great benefits of doing a proof of idea together with your community design. The proof of idea check outcomes must be examined and used to switch present infrastructure, safety and administration specs earlier than producing a design proposal. The proof of idea mannequin prompt right here includes prototype design, gear provisioning, defining exams, constructing gear scripts and analyzing check outcomes.

B. Prototype Design

P. Provision Equipment

O. Define Tests

A. Build Equipment Scripts

H. Review Test Results


With the proof of idea completed, you at the moment are able to construct a design proposal for the design assessment assembly. Your meant viewers might be the Director, CIO, CTO, Senior Network Engineer, Consultant or anybody that’s approving a finances for the challenge. It is essential to current your concepts with readability and professionalism. If a presentation is required, energy level slides work properly and could possibly be used to help ideas from the design proposal doc. The focus is on what includes a normal design proposal and the sequence for presenting that info.

The working design proposal is introduced to the shopper after addressing any considerations from proof of idea assurance testing. The design assessment is a chance so that you can current your design proposal to the shopper and talk about any points. It is a chance for the shopper to determine considerations they’ve and for the design engineer to make clear points. The focus is to agree on any modifications, if required, and make modifications to the infrastructure, safety and administration earlier than implementation begins. Business and design necessities can change from when the challenge began which typically will necessitate modifications to infrastructure, safety and administration specs. Any modifications ought to then undergo proof of idea testing once more earlier than last modifications to the design proposal.


The last step may have us defining an implementation course of for the required design. This describes a prompt implementation methodology of the proposed design, which ought to have minimal disruption to the manufacturing community. As properly it must be environment friendly and as value efficient as attainable. As with earlier methodologies there’s a sequence that ought to be utilized as properly. Once the implementation is completed, there’s monitoring of the community for any issues. Design and configuration modifications are then made to deal with any issues or considerations.
