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).
There are three faces in the IIN design.
- Integrated transport: Voice, Video and Data are joined and transported together.
- Integrated services: For exampel Storage (SAN), voice
- Integrated Applications:

PPDIOO
| 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.
