How does QOS work when used on your WAN links, does it wait until the link is degrading before executing and if so, how does it compute this? For instance, I know that telnet and ftp are quite high from via sniffer. Is it feasible to implement a QOS to conserve my bandwidth for my critical applications now, or wait unlit people yell. Can I turn it on to protect bandwidth utilization and if so what flavor would you recommend. Particularly for SNA/STUN. Thanks in Advance.
