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.
