Abstract
Techniques are provided for improve quality of service on uplinks in a virtualized environment. At a server apparatus having a plurality of physical links configured to communicate traffic over a network to or from the server apparatus, forming an uplink group comprising a plurality of physical links. A first class of service is defined that allocates a first share of available bandwidth on the uplink group, and a second class of service is defined that allocates a second share of available bandwidth on the uplink group. The bandwidth for the first class of service is allocated across the plurality of physical links of the uplink group, and the bandwidth for the second class of service is allocated across the plurality of physical links of the uplink group. Traffic rates are monitored on each of the plurality of physical links to determine if a physical link is congested indicating that a bandwidth deficit exists for a class of service. In response to determining that one of the plurality of physical links is congested, bandwidth is reallocated for a class of service to reduce the bandwidth deficit for a corresponding class of service.
