Abstract: In one embodiment, a method includes receiving current weight data from one or more hosts associated with a virtual server and configuring a maximum weight of the virtual server. The method includes communicating the sum of the current weight data from all of the hosts to a global loadbalancer and communicating the maximum weight of the virtual server to the global loadbalancer.

Abstract: Support for over-subscription while maintaining priorities (e.g., CBR, VBR RT, VBR nRT, UBR, in that order from high to low) and ensuring that each virtual circuit does not exceed any allocated bandwidth. In an embodiment, a line slot credit is maintained associated with each virtual circuit, which is incremented by a token value (equivalent to a cell slot for transmission on the communication path) in each cell slot. When the line slot credit equals or exceeds a inter-cell delay for the virtual circuit, a VC-credit associated with the virtual circuit is incremented unless the VC-credit value would exceed any maximum threshold value. Cells are transmitted (for VC-types with allocated bandwidths) if the associated VC-credit is at least one, while maintaining priorities by VC-type. PCR may also be enforced on VBR and UBR VC-types.
