Multitenancy for Fast and Programmable Networks in the Cloud

" summary

Claims that a hybrid compile-time linker plus a runtime stateful-memory allocator lets multiple tenant P4 programs share a Barefoot Tofino ASIC with low overhead and isolation. Prototype uses an open-source P4 compiler, a Tofino packet-test framework and control-plane APIs to pull counters and rewrite table entries. Evaluation consolidates programs (merged resource use usually < sum, except for gateway tables and extra header containers), and a 64-tenant, 10‑minute trace shows dynamic allocation yields higher memory hit and satisfaction (5th‑percentile) than static allocation.
