What would he do if he had a FR link to a remote site and he wanted to ensure his high priority traffic was sent without DE, whilst low priority traffic can burst and be sent as DE - does FRTS (for Telnet only) solve this problem (if that can be done)?

Normal traffic despools after telnet queue is empty. If you are sure that there will always be bandwitfh left for other traffic, PQ will do fine. That is one way of using it. >>> During transmission, PQ gives priority queues absolute preferential treatment over low priority queues; important traffic, given the highest priority, always takes precedence over less important traffic. Packets are classified based on user-specified criteria and placed into one of the four output queues-high, medium, normal, and low-based on the assigned priority. Packets that are not classified by priority fall into the normal queue. Figure 7 illustrates this process. Congestion Management Overview http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/qos_c /qcpart2/qcconman.htm Why Use Priority Queueing? PQ provides absolute preferential treatment to high priority traffic, ensuring that mission-critical traffic traversing various WAN links gets priority treatment. In addition, PQ provides a faster response time than do other methods of queueing. Although you can enable priority output queueing for any interface, it is best used for low-bandwidth, congested serial interfaces. Considerations When choosing to use PQ, consider that because lower priority traffic is often denied bandwidth in favor of higher priority traffic, use of PQ could, in the worst case, result in lower priority traffic never being transmitted. To avoid inflicting these conditions on lower priority traffic, you can use traffic shaping or CAR to rate-limit the higher priority traffic. PQ introduces extra overhead that is acceptable for slow interfaces, but may not be acceptable for higher speed interfaces such as Ethernet. With PQ enabled, the system takes longer to switch packets because the packets are classified by the processor card. PQ uses a static configuration and does not adapt to changing network conditions. >>>>>> Martijn - -----Oorspronkelijk bericht----- Van: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Namens Julian P Verzonden: maandag 20 januari 2003 9:02 Aan: [EMAIL PROTECTED] Onderwerp: QOS on 2621xm [7:61353] Hi We would like to prioritize incoming traffic on our 256k internet link to uunet .We need to give telnet at least 64k incoming bandwidth.
