Abstract:
1. A method comprising: at a server apparatus having a plurality physical links configured to communicate traffic over a network to or from the server apparatus, forming an uplink group comprising the plurality of physical links, wherein the plurality of physical links comprises a first physical link and a second physical link; defining a plurality of classes of service comprising a first class of service and a second class of service, wherein each of the plurality of classes of service corresponds to a predetermined class bandwidth; allocating a first predetermined class bandwidth for the first class of service across the plurality of physical links of the uplink group; allocating a second predetermined class bandwidth for the second class of service across the plurality of physical links of the uplink group; monitoring traffic rates on the plurality of physical links to detect congestion indicating that a bandwidth level for any class in the plurality of classes of service is below the corresponding predetermined class bandwidth; and in response to detecting that the first physical link is congested, and that the first class of service has a bandwidth deficit corresponding to a bandwidth level below the first predetermined class bandwidth, reallocating bandwidth on the second physical link from the second class of service to the first class of service by increasing bandwidth allocation for the first class of service on the second physical link and decreasing bandwidth allocation for the second class of service on the second physical link such that the bandwidth deficit is reduced.
