Planning Approaches To develop a successful network design, a proper planning approach is required to build a coherent strategy for the overall design. Network designers can follow two common planning approaches to develop business-driven network designs and facilitate the design decisions: ■ Strategic planning approach: Typically targets planning to long-term goals and strategies. For example, a service provider needs to migrate its core from legacy (ATM) to be based on MPLS instead. The design decision in this approach has to cater to long-term goals and plans. ■ Tactical planning approach: Typically targets planning to overcome an issue or to achieve a short-term goal. For instance, an enterprise might need to provide remote access to some partners temporally (for example, over the Internet) until dedicated extranet connectivity is provisioned. Design decisions in this approach generally need to provide what is required within a limited period of time and are not necessarily required to consider long-term goals.
