Quality of Service standards

Every customer will have different expectations and different budgets to work to. Some will be willing to upgrade their networks to use the best possible equipment and practices. To others the additional expense may be viewed as unnecessary. Examples of standards based Quality of Service protocols include:
  • 802.1Q (Layer 2)
  • DiffServ (Layer 3)
  • Port Range (Layer 4)
  • 802.1X (MD-5)
