Network Design & Implementation

Your computer network is the foundation upon which all other IT services operate. Without a well planned and implemented network all other IT services are at risk of failure which in turn puts your business at risk.

Layer3 Networks specialize in providing comprehensive network design solutions for businesses. Our team of design engineers have vast amounts of experience in designing, implementing and supporting networks of all sizes and complexities having designed networks for small offices right up to complex datacentre networks for financial institutions.

When designing a network a thorough understanding of the business objectives and the appropriate technology to achieve those objectives needs to be understood by the design team. Clearly, performance is critical, however, future requirements must also be taken into consideration and therefore the design needs to be scalable and within the budget.

To consistently achieve these requirements, Layer3 Networks follow the proven Cisco design mothodolgy outlined below:

 

  • Preparation

Business agility starts with prepareation: anticipating the broad vision, requirements, and technologies needed to build and sustain a competative advantage. In the prepare phase a company determines a business case and a financial rationale to support the adoption of a new technology. By carefully anticipating future needs and developing both a technology strategy and a high-level architecture to meet those needs, a business is better equiped to contain costs during deployment and operations.
    

  • Planning

Successful technology deployment depends on an accurate assesment of a comapny's current network, security state, and overall readiness to support the proposed solution. In the plan phase a company ascertains whether it has adequate resources to manage a technology deployment project to completion. To evaluate and improve network security a company tests it's network for vulnerabilty to intruders and outside networks. the company then developes a detailed project plan to identifyresources, potentiaal difficulties, individual responsibilities and critical tasks necessary to deliver the final project on time and on budget. 
    

  • Design

Developing a detailed design is essential to reducing risk, delays and the total cost of network deployments. A design aligned with business goals and requirements can improve network performance while supporting high availability, reliability, security and scalability. Day-to-day operations and network management processes need to be anticipated and when necessary custom applications are created to integrate new systems in to existing infrastructure. The design phase can also guide and accelerate successful with a plan to stage, configure, test and validate network operations.
    

  • Implimentation

A network is essential to any successful organisation and it must deliver vital services without disruption. In the implement phase a company works to integrate devices and new capabilities in accordance with the design - without comprimising network availability or performance. After indentifying and resolving potential problems, the company attempts to speed return on investment with and efficient migration and successful implementation, including installing, configuring, integrating, testing and commissioning all systems. After network operation is validated an organisation can begin expanding and improvoing IT staff skills to further increase productivity and reduce system downtime. 
    

  • Operation

Network operations represent a significant portion of IT budgets, so it's important to be able to reduce operating expenses while continuallhy enhancing performance. Throughout the operate phase a company proactively monitors the health and vital signs of the network to improve service quality; reduce disruptions; mitigate outages; and maintain high availability, reliability and security. by providing an efficient framework to operational tools to respond to problems a company can avoid costly downtime and business interruption. Expert operations also allow an organisation to accommodate upgrades, moves, additions and changes
    

  • Optimization

Involves proactive management of the network. The goal of proactive management is to identify and resolve issues before they affect the organization. Reactive fault detection and correction (troubleshooting) is needed when proactive management cannot predict and mitigate failures. In the PPDIOO process, the optimization phase can prompt a network redesign if too many network problems and errors arise, if performance does not meet expectations, or if new applications are identified to support organizational and technical requirements.
