Abstract
In order to support new network architectures, Openflow implements flows forwarding based on multiple tables via pipelines, which increases the difficulty of the implementation. With the advent of multi-core CPU, a software defined data plane, LabelCast, is proposed, which characterizes the ability of forwarding operations and processing services through the Label table and Cast table. Forwarding layer lookups based on fixed-length labels and schedules packets processing, including light-semantics action instructions of general process, which is easy to be realized and is denoted by the Label table, and protocol semantics or status-related service of special process, which could be enriched via opening resources within network devices and is arranged by the Cast table. LabelCast supplies a reliable and programmable data plane, and could load multiple network architectures, so as to facilitate Internet innovation.
