我们提出了令牌信元路由（TCR），一个新的子IP层协议，提供了一个强大的硬件友好的方法来构建数据平面数据包，以满足新的应用程序的需求。令牌单元是一种特殊的轻度结构化令牌，可以使用不同的语义编程以服务于不同的目的。TCR数据包由一系列令牌单元组成，每个令牌单元与特定功能相关联。使用最长前缀匹配，调用代码点来实现特定于令牌单元格类型的逻辑。数据包还定义了令牌单元处理工作流，并允许令牌单元交叉引用数据。这导致能够编程非常强大的功能。同时，处理保持简单，允许能够以线速率操作的直接实现。TCR目前仍处于概念阶段，正在探索概念验证和标准化场所。
We present Token Cell Routing (TCR), a new sub-IP layer protocol that provides a powerful yet hardware-friendly method of constructing data plane packets to meet the needs of new applications. Token cells are a special kind of lightly structured token which can be programmed with different semantics to serve different purposes. A TCR packet consists of a series of token cells, each associated with a certain functionality. Using longest prefix matching, code points are invoked that implement logic specific to the token cell's type. Packets also define token cell processing workflows and allow token cells to cross-reference data. This results in the ability to program very powerful functionality. At the same time, processing is kept simple, allowing for straightforward implementations able to operate at line rate. TCR is currently still in the concept stage while proofs-of-concepts and venues for standardization are being explored.
