Network Working Group D. Waitzman Request for Comments: 2549 IronBridge Networks Updates: 1149 1 April 1999 Category: Experimental IP over Avian Carriers with Quality of Service Status of this Memo This memo defines an Experimental Protocol for the Internet community. It does not specify an Internet standard of any kind. Discussion and suggestions for improvement are requested. Distribution of this memo is unlimited. Copyright Notice Copyright (C) The Internet Society (1999). All Rights Reserved. Abstract This memo amends RFC 1149, "A Standard for the Transmission of IP Datagrams on Avian Carriers", with Quality of Service information. This is an experimental, not recommended standard. Overview and Rational The following quality of service levels are available: Concorde, First, Business, and Coach. Concorde class offers expedited data delivery. One major benefit to using Avian Carriers is that this is the only networking technology that earns frequent flyer miles, plus the Concorde and First classes of service earn 50% bonus miles per packet. Ostriches are an alternate carrier that have much greater bulk transfer capability but provide slower delivery, and require the use of bridges between domains. The service level is indicated on a per-carrier basis by bar-code markings on the wing. One implementation strategy is for a bar-code reader to scan each carrier as it enters the router and then enqueue it in the proper queue, gated to prevent exit until the proper time. The carriers may sleep while enqueued. For secure networks, carriers may have classes Prime or Choice. Prime carriers are self-keying when using public key encryption. Some distributors have been known to falsely classify Choice carriers as Prime. Packets MAY be marked for deletion using RED paint while enqueued. Waitzman Experimental [Page 1]

RFC 2549 IP over Avian Carriers with QoS 1 April 1999 X =============================== ^ | ========= Carriers in the queue too long may leave log entries, as shown on the scale. The following is a plot of traffic shaping, from coop-erative host sites. Alt | Plot of Traffic Shaping showing carriers in flight | 2k | .................... | . . | . . 1k | . . | +---+ +---+ | | A | | B | | +---+ +---+ |_____________________________________________ Avian carriers normally bypass bridges and tunnels but will seek out worm hole tunnels. When carrying web traffic, the carriers may digest the spiders, leaving behind a more compact representation. The carriers may be confused by mirrors. Round-robin queueing is not recommended. Robins make for well-tuned networks but do not support the necessary auto-homing feature. A BOF was held at the last IETF but only Avian Carriers were allowed entry, so we don't know the results other than we're sure they think MPLS is great. Our attempts at attaching labels to the carriers have been met with resistance. Waitzman Experimental [Page 2]
