Abstract
A quality of service (QoS) notification module can provide detection and notification of violation of allocated QoS to a transmission queue. The QoS notification module can be located on a network adapter and send notifications to a host computer coupled to the network adapter. QoS notifications can indicate that one or more host transmission queues are being underserved, i.e., the bandwidth guaranteed to the one or more host queues is not being met despite the queues not being empty. Notification module can send notification to the host by writing to a memory location or a notification register in the memory of the host. Alternatively, the notification module can send an interrupt to the host processor, the interrupt including QoS notification information. The notification module can also be located in a switch for generating notifications of QoS violations of bandwidth guarantees for transmission queues associated with transmission ports of the switch.
