Quality of Service
This post looks at the basics of QoS and what can be done within my network to promote certain application behaviors at the expense of others. Background First some basics. IP QoS is only beneficial when resources such as bandwidth are limited and congestion occurs. Therefore one way to avoid the need for IP QoS is to have unlimited (or at least beyond your needs) resources. This is...
