Rings, memory, interrupts, DMA channels, and flow table entries are shared resources within the data movement architecture and their ownership and use must be managed in order to provide stable, safe, and secure operation. The DMSS provides channelized firewalls which can be used to protect arrayed resources (like rings, channel control MMRs, etc.) from unwanted/unauthorized use as well as restricted access to the firewall configurations themselves. It is outside the scope of this document to define how the resource management system functions but it is assumed that all of these resources are isolate-able and secure-able.
