Our paper “OpenDesc: From Static NIC Descriptors to Evolvable
Metadata Interfaces” will be presented today at HotNets’25.
In OpenDesc, we propose to use P4 as an interface to define packet descriptors. OpenDesc enables to expose NIC capabilities and match them with application intents. We propose a prototype compiler to generate accessors that can directly extract metadata from a negotiated NIC descriptor without the need for intermediate data structures like sk_buff, xdp_sock, rte_mbuf & cie.
