Abstract
Methods and apparatus for determining and adjusting traffic rate limits to reduce queuing delays and latency in a data center network. In various embodiments, a network controller receives network topology information and traffic data relating to flows of the network. The traffic data includes traffic matrix information, flow path information, and pause frame distribution information. Based on this information, the network controller identifies server network node interfaces that are the source of a pause frame. Flows associated with such network node interfaces are also identified and ranked based on traffic volume. For ranked flows meeting predetermined criteria, reduced traffic rate limits are calculated and sent to associated server network node interfaces. In some embodiments, the reduced traffic rate limits are incrementally recovered when normal traffic resumes on a paused link. In further embodiments, traffic rate limits are also adjusted for flows of highly utilized and underutilized network node interfaces.
