QOS Best Practices - What is best practice ? Below is a Wikipedia definition of best practice. This apply to education as well. A best practice is a method or technique that has been generally accepted as superior to any alternatives because it produces results that are superior to those achieved by other means or because it has become a standard way of doing things, e.g., a standard way of complying with legal or ethical requirements.
Always classify and mark applications as close to their sources as possible. Although in real life designs we may not be able to follow best practice network design due to many constraints such as technical , budgetary or political constrains, knowing the best practices is very critical for network design in real life as well as in the exams.
Thus below are the general accepted Quality of Service Best Practices. I covered Quality of Service Best Practices and the many other technology best practices in the CCDE In-Depth which is my latest network design book.
