Multilayer quality of service (qos) for network function virtual platforms

Abstract

The present application discloses a multi-layer quality of service (QoS) for a network function virtualization platform, and provides a virtualization platform for network function virtualization (NFV). 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 NFV flexibility and agility. Traffic at the NFV platform can be controlled by a distributed quality of service (QoS) manager. The distributed QoS manager may include a plurality of QoS modules, each of the plurality of QoS modules for performing priority queuing independently of its associated components or interfaces. 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 packets received at external network ports, A third QoS module for arbitrating between memory accesses at the external memory interface of the device, a fourth QoS module for arbitrating access among multiple hardware accelerator chips, and the like.

Description

[0001] This application claims priority to US Patent Application No. 14 / 724,089, filed May 28, 2015, which is incorporated herein by reference in its entirety. technical field [0002] Embodiments of the present invention relate to network function virtualization (NFV), and more particularly to hardware acceleration for NFV. Background technique [0003] The growth of the internet has helped create the web of networks that link together billions of devices across the globe. Typically, the fastest and most reliable networks are built using custom application-specific integrated circuits (ASICs) and dedicated hardware. As a result, large enterprise networks often resemble complex monolithic systems. In such custom systems, ad-hoc additions and changes to these systems without any disruption to the network can be very challenging. [0004] As recent networks have focused on advances in commodity computing hardware, services that previously could only be provided through propr...
