Abstract
摘要
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.
本备忘录修订了RFC 1149“鸟类载体IP数据报传输标准”，并提供了服务质量信息。这是一个实验性的标准，不是推荐的标准。
Overview and Rational
概述与理性
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.
可提供以下服务质量级别：协和、First、Business和Coach。协和式飞机提供快速数据传输。使用鸟类航空公司的一个主要好处是，这是唯一能赚取常客里程的联网技术，再加上协和式飞机和头等舱服务，每包可获得50%的额外里程。鸵鸟是一种替代性运输工具，具有更大的批量运输能力，但运输速度较慢，并且需要使用域之间的桥梁。
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.
每个承运人的服务水平由机翼上的条形码标记表示。一种实现策略是，条形码阅读器在每个载波进入路由器时扫描它，然后将其放入适当的队列中，在适当的时间之前进行选通以防止退出。运营商可能在排队时睡眠。
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.
对于安全网络，运营商可以选择Prime或Choice。当使用公钥加密时，主载波是自密钥的。众所周知，一些分销商错误地将精品航空公司归类为优质航空公司。
Packets MAY be marked for deletion using RED paint while enqueued.
在排队时，可以使用红色油漆将数据包标记为删除。
Weighted fair queueing (WFQ) MAY be implemented using scales, as shown:
加权公平排队（WFQ）可以使用scales实现，如图所示：
__
_____/-----\ / o\
<____ _____\_/ >--
+-----+ \ / /______/
| 10g | /|:||/
+-----+ /____/|

Carriers in the queue too long may leave log entries, as shown on the scale.
队列中的运营商太长可能会留下日志条目，如磅秤上所示。

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.
鸟类携带者通常绕过桥梁和隧道，但会寻找虫洞隧道。当承载网络流量时，载体可能会消化蜘蛛，留下更紧凑的表示。反射镜可能会混淆载体。
Round-robin queueing is not recommended. Robins make for well-tuned networks but do not support the necessary auto-homing feature.
不建议使用循环排队。Robins可以很好地调整网络，但不支持必要的自动归位功能。
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.
上一次IETF举行了BOF，但只有鸟类携带者被允许进入，因此我们不知道结果，我们确信他们认为MPLS很棒。我们在航空母舰上贴标签的尝试遭到了抵制。
NATs are not recommended either -- as with many protocols, modifying the brain-embedded IP addresses is difficult, plus Avian Carriers MAY eat the NATs.
NAT也不被推荐——正如许多协议一样，修改大脑中嵌入的IP地址很困难，而且鸟类携带者可能会吃掉NAT。
Encapsulation may be done with saran wrappers. Unintentional encapsulation in hawks has been known to occur, with decapsulation being messy and the packets mangled.
封装可以用saran包装纸完成。已知hawks中会发生非故意的封装，去封装会变得凌乱，数据包也会损坏。
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.
松散源代码路由是一种可行的进化替代方案，增强了基于标准的MSWindows兼容技术，但不能使用严格的源代码路由，因为它们是一个瓶颈。
The ITU has offered the IETF formal alignment with its corresponding technology, Penguins, but that won't fly.
国际电联已经向IETF提供了与其相应的技术企鹅（Penguins）的正式校准，但这不会成功。
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 propagate via an inheritance tree. The carriers have an average TTL of 15 years, so their use in expanding ring searches is limited.
支持多播，但需要实现克隆设备。如果运营商是基于正在修剪的树，则运营商可能会丢失。载体通过继承树传播。运营商的平均TTL为15年，因此它们在扩展环形搜索中的使用是有限的。

The carriers will not line up in lexigraphic order but will naturally order in a large V shape. Bulk retrieval is possible using the Powerful Get-Net operator.
载体不会以字母顺序排列，但自然会以大V形排列。使用功能强大的Get-Net操作符可以进行批量检索。
