Network scheduler in a distributed storage system

A computer system comprising:

• a sensor configured to determine a first network congestion condition at a first host;
• a scheduler configured to determine a first packet delay time based on at least the first network congestion condition;
• the scheduler further configured to delay transmitting the first data packet, from the first host across a network to a second host, by the first packet delay time, based on at least a first data packet belonging to a first traffic class of a plurality of traffic classes;
• and
• a transmitter configured to transmit the second data packet from the first host to the second host without a delay from the scheduler, based on at least a second data packet belonging to a second traffic class of the plurality of traffic classes.

A non-transitory computer storage medium having stored thereon program code executable by a processor, the program code embodying a method comprising:

• determining a first network congestion condition at a first host;
• based on at least the first network congestion condition, determining a first packet delay time;
• based on at least a first data packet belonging to a first traffic class of a plurality of traffic classes, delaying transmitting the first data packet, from the first host across a network to a second host, by the first packet delay time;
• and
• based on at least a second data packet belonging to a second traffic class of the plurality of traffic classes, transmitting the second data packet from the first host to the second host without a delay.
