Bandwidth guarantee and work conservation

A bandwidth guarantee and work conservation apparatus comprising:

• a memory storing a module comprising machine readable instructions to:
• determine virtual machine (VM) bandwidth guarantees assigned to VMs in a network including a source VM that communicates with destination VMs;
• and
• assign minimum bandwidth guarantees to communications between the source VM with the destination VMs based on VM-to-VM communications between the source VM and the destination VMs;
• and
• a processor to implement the module;
• wherein the instructions to assign minimum bandwidth guarantees include instructions to:
• determine a first minimum bandwidth guarantee value for a communication from the source VM to an endpoint VM that is one of the destination VMs;
• determine a second minimum bandwidth guarantee value for a communication from the endpoint VM to the source VM;
• and
• select a minimum bandwidth guarantee for the communication from the source VM to the endpoint VM, based on the first minimum bandwidth guarantee value and the second minimum bandwidth guarantee value.

A non-transitory computer readable medium having stored thereon machine readable instructions for bandwidth guarantee and work conservation, the machine readable instructions when executed to cause a computer system to:

• determine virtual machine (VM) bandwidth guarantees assigned to VMs in a network including a source VM that communicates with destination VMs;
• assign minimum bandwidth guarantees to communications between the source VM with the destination VMs;
• wherein the machine readable instructions to assign minimum bandwidth guarantees include machine readable instructions that when executed cause a computer system to:
• determine a first minimum bandwidth guarantee value for a communication from the source VM to an endpoint VM that is one of the destination VMs;
• determine a second minimum bandwidth guarantee value for a communication from the endpoint VM to the source VM;
• and
• select a minimum bandwidth guarantee for the communication from the source VM to the endpoint VM, based on the first minimum bandwidth guarantee value and the second minimum bandwidth guarantee value.
