RFC 1149, "A Standard for the Transmission of IP Datagrams on Avian Carriers", with Quality of Service information. Overview and Rational The following quality of service levels are available: Concorde, First, Business, and Coach. 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. 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. 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.
When carrying web traffic, the carriers may digest the spiders, leaving behind a more compact representation. 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. Page 3 NATs are not recommended either -- as with many protocols, modifying the brain-embedded IP addresses is difficult, plus Avian Carriers MAY eat the NATs. Unintentional encapsulation in hawks has been known to occur, with decapsulation being messy and the packets mangled. Loose source routes are a viable evolutionary alternative enhanced standards-based MSWindows-compliant technology, but strict source routes MUST NOT be used, as they are a choke-point. The ITU has offered the IETF formal alignment with its corresponding technology, Penguins, but that won't fly. Multicasting is supported, but requires the implementation of a clone device. Carriers may be lost if they are based on a tree as it is being pruned. The carriers have an average TTL of 15 years, so their use in expanding ring searches is limited. Additional quality of service discussion can be found in a Michelin's guide. Bulk retrieval is possible using the Powerful Get-Net operator. Specification of Requirements In this document, several words are used to signify the requirements of the specification. Security Considerations There are privacy issues with stool pigeons. Patent Considerations There is ongoing litigation about which is the prior art: carrier or egg.
