What are network design methodologies?

What are network design methodologies?

The network design methodology presented in this section is derived from the Cisco Prepare, Plan, Design, Implement, Operate, and Optimize (PPDIOO) methodology, which reflects a network’s lifecycle. The output of this phase is a set of network requirements.

What is Ppdioo methodology?

PPDIOO stands for Prepare, Plan, Design, Implement, Operate, and Optimize. PPDIOO is a Cisco methodology that defines the continuous life-cycle of services required for a network.

Which are the three steps in the design methodology?

The Three Phases of Design Thinking: Immersion, Ideation and Prototyping. The Design Thinking approach have changed the way thousands of companies think (and do) innovation. Start your transformation from its 3 basic standards: Immersion, Ideation and Prototyping.

What is the purpose of network design?

The objective of network design is to satisfy data communication requirements while minimizing expense. Requirement scope can vary widely from one network design project to another based on geographic particularities and the nature of the data requiring transport.

What are the main phases of network design?

In its simplest form, network lifecycle management consists of three phases: plan, build and manage. It is also known as design, implement and operate (DIO). The cycle is repeated as the plan phase identifies new requirements. The lifecycle process can also be applied to subtasks.

What are the two basic design of a computer network?

Network Design Computer networks can have different designs, with the two basic forms being client/server and peer-to-peer networks.

What should be included in network design?

Network design will typically include the cabling structure, a logical map of the network to be implemented, the quantity of network devices, the type of network devices, the location of network devices, the IP addressing structure, and the network security architecture.

What is Cisco SONA?

The Cisco Service-Oriented Network Architecture (SONA) framework outlines how enterprises can evolve their IT infrastructure into an Intelligent Information Network that accelerates applications, business processes and resources, and enables IT to have a greater impact on business.

What are the key design issues of a computer network?

Design Issues for the Layers of Computer Networks

  • Reliability. Network channels and components may be unreliable, resulting in loss of bits while data transfer.
  • Scalability. Networks are continuously evolving.
  • Addressing.
  • Error Control.
  • Flow Control.
  • Resource Allocation.
  • Statistical Multiplexing.
  • Routing.

What is the need for a design methodology?

Design methodology stresses the use of brainstorming to encourage innovative ideas and collaborative thinking to work through each proposed idea and arrive at the best solution. Meeting the needs and wants of the end user is the most critical concern.

How to test the network design and implementation?

During the network designing and implementation when you finish a new module of network or deploy the design to small site, before the full implementation, it is a best practiceto test the new solution. This testing can be done in one of two ways: prototype orpilot.

What is the top-down approach to design a network?

Cisco recommends you to use the top-down approach for designing the network topology and solution. Aspart of the Design phase you can use PPDIOO methodology, or a top-down approach is usedthat begins with the organization’s requirements before looking at technologies.

How to design a network topology?

After selecting the network design methodology, you need to design you network topology. You can use the top-down design approach for designing the network topology. Top-down design just means starting your design from the top layer of the OSI model and working your way down.

What is a network design document?

The design document describes the business requirements, old network architecture, network requirements; and design, plan, and configuration information for the new network. The network designers, architects and analysts use it to document the new network changes, and it serves as documentation for the enterprise.
