All Rights Reserved.<br><br>Abstract<br><br> This memo amends RFC 1149, "A Standard for the Transmission of IP<br> Datagrams on Avian Carriers", with Quality of Service information.<br> This is an experimental, not recommended standard.<br><br>Overview and Rational<br><br> The following quality of service levels are available: Concorde,<br> First, Business, and Coach. Concorde class offers expedited data<br> delivery. One major benefit to using Avian Carriers is that this is<br> the only networking technology that earns frequent flyer miles, plus<br> the Concorde and First classes of service earn 50% bonus miles per<br> packet. Ostriches are an alternate carrier that have much greater<br> bulk transfer capability but provide slower delivery, and require the<br> use of bridges between domains.<br><br> The service level is indicated on a per-carrier basis by bar-code<br> markings on the wing. One implementation strategy is for a bar-code<br> reader to scan each carrier as it enters the router and then enqueue<br> it in the proper queue, gated to prevent exit until the proper time.<br> The carriers may sleep while enqueued.<br><br> For secure networks, carriers may have classes Prime or Choice.<br> Prime carriers are self-keying when using public key encryption.<br> Some distributors have been known to falsely classify Choice carriers<br> as Prime.<br><br> Packets MAY be marked for deletion using RED paint while enqueued.<br> Weighted fair queueing (WFQ) MAY be implemented using scales, as<br> shown:<br><br> __<br> _____/-----\ / o\<br> &gt;--<br> +-----+ \ / /______/<br> | 10g | /|:||/<br> +-----+ /____/|<br> | 10g | |<br> +-----+ .. X<br> ===============================<br> ^<br> |<br> =========<br><br> Carriers in the queue too long may leave log entries, as shown on the<br> scale.<br><br> The following is a plot of traffic shaping, from coop-erative host<br> sites.<br><br><br>Alt | Plot of Traffic Shaping showing carriers in flight<br> |<br>2k | ....................<br> | . .<br> | . .<br>1k | . .<br> | +---+ +---+<br> | | A | | B |<br> | +---+ +---+<br> |_____________________________________________<br><br><br> Avian carriers normally bypass bridges and tunnels but will seek out<br> worm hole tunnels. When carrying web traffic, the carriers may<br> digest the spiders, leaving behind a more compact representation.<br> The carriers may be confused by mirrors.<br><br> Round-robin queueing is not recommended. Robins make for well-tuned<br> networks but do not support the necessary auto-homing feature.<br><br> A BOF was held at the last IETF but only Avian Carriers were allowed<br> entry, so we don't know the results other than we're sure they think<br> MPLS is great. Our attempts at attaching labels to the carriers have<br> been met with resistance.
