Multilayer quality of service (QOS) for network functions virtualization platforms
A virtualization platform for Network Functions Virtualization (NFV) is provided. The virtualization platform may include a host processor coupled to an acceleration coprocessor. The acceleration coprocessor may be a reconfigurable integrated circuit to help provide improved flexibility and agility for the NFV. The traffic at the NFV platform may be controlled by a distributed Quality of Service (QoS) manager. The distributed QoS manager may include multiple QoS modules each of which serves to perform priority queuing independently for its associated component or interface. For example, the NFV platform may include a first QoS module for arbitrating among multiple virtual machines, a second QoS module for performing priority queuing for data packets received at an external network port, a third QoS module for arbitrating among memory accesses at a coprocessor external memory interface, fourth QoS module for arbitrating accesses among multiple hardware acceleration slices, etc.
