Chapter 12. Optimizing Application Delivery in Storage-Based Networking, Wireless LANs, and an End-to-End Model
This chapter includes the following topics:
For years, network performance problems were solved with additional bandwidth. For underperforming applications, the first choice often has been to add servers and processing power. Hardware and bandwidth are relatively inexpensive, but IT managers have a difficult time scaling fast enough to keep up with the exploding amount and diversity of application traffic. Web surfing, e-mail, and streaming video and audio can hog bandwidth and degrade the performance of mission-critical applications such as customer relationship management (CRM) and enterprise resource planning (ERP). Adding more bandwidth might only improve the response of nonessential applications; it does not guarantee that the bandwidth will be available to the applications that need it most.
This chapter concentrates on the design issues and considerations with methodology approaches for storage-area networks, wireless LANs, and an end-to-end model. Basic design is considered very important in any optimization methodology. No amount of optimization will compensate for a poor base design.
Each study can stand alone as isolated design considerations, or they can be merged to form a more holistic view of requirements for different scenarios.
