Strategic network design

Cisco Service-Oriented Network Architecure (SONA) describes a model for design of networks. Cisco updated their designmodel from Architecture for Voice, Video and Integrated Data(AVVID) to Intelligent Information Network (IIN).

Cisco SONA three layeer design model

There are three faces in the IIN design.

  1. Integrated transport: Voice, Video and Data are joined and transported together.
  2. Integrated services: For exampel Storage (SAN), voice
  3. Integrated Applications:

PPDIOO

PPDIOO Network live-cycle phases (Prepare, Plan, Design, Implement, Operate og Optimize)
PPDIOO aktivitet Description
Prepare DThe Prepare phase establishes organization and business requirements, develops a network

strategy, and proposes a high-level architecture to support the strategy. Technologies that support the architecture are identified. This phase creates a business case to establish a financial justification for a network strategy.

Plan The Plan phase identifies the network requirements by characterizing and assessing the network,

performing a gap analysis against best-practice architectures, and looking at the operational environment. A project plan is developed to manage the tasks, responsible parties, milestones, and resources to do the design and implementation. This project plan is followed during all phases of the cycle.

Design The network design is developed based on the technical and business requirements obtained from

the previous phases. The network design provides high availability, reliability, security, scalability, and performance. The design includes network diagrams and an equipment list. The project plan is updated with more granular information for implementation. After the Design phase is approved, the Implement phase begins.

Implement New equipment is installed and configured in the Implement phase. New devices replace or

augment the existing infrastructure. The project plan is followed during this phase. Planned network changes should be communicated in change control meetings, with necessary approvals to proceed. Each step in the implementation should includes a description, detailed implementation guidelines, estimated time to implement, rollback steps in case of a failure, and any additional reference information. As changes are implemented they are also tested before moving to the Operate phase.

Operate The Operate phase maintains the network’s day-to-day operational health. Operations include

managing and monitoring network components, routing maintenance, managing upgrades, managing performance, and identifying and correcting network faults. This phase is the design’s final test. During operation, network management stations should monitor the network’s general health and generate traps when certain thresholds are reached.

Optimize The Optimize phase involves proactive network management by identifying and resolving issues

before they affect the network. The Optimize phase may create a modified network design if too many network problems arise, to improve performance issues, or to resolve application issues. The requirement for a modified network design leads to the network life cycle beginning.

Top-down or Bottom-up design

Top-down design

Incorporates the organization’s requirements. Provides the big picture. The design meets current and future requirements.

  • Disadvantages:
    • Time demanding
    • Expensive short term.

Bottom-up design

The design is based on previous experience and allows for a quick solution.

  • Disadvantages:
    • May result in inappropriate design.
    • Organizational requirements are not included.

Section Description
Introduction describes the project’s purpose and the reasons for the network design.
Design Requirements lists the organization’s requirements, constraints, and goals.
Existing Network Infrastructure includes logical (Layer 3) topology diagrams; physical topology diagrams; audit results; routing protocols; a summary of applications; a list of network routers, switches, and other devices; configurations; and a description of issues.
Design contains the specific design information, such as logical and physical topology, IP

addressing, routing protocols, and security configurations.

Proof of Concept results from live pilot or prototype testing.
Implementation plan includes the detailed steps for the network staff to implement the new

installation and changes.

Appendixes contains additional information and configurations.

Optimization of communication between applications and services by using intelligent network services such as security, virtualization and Quality of Service (QoS)
