Controlling a transmission rate of packet traffic includes receiving packets from a network processor. The packets are stored in a buffer associated with a processor. If an occupancy level of the buffer is greater than a predetermined threshold, it is determined that the processor is congested. A message is transmitted to the network processor indicating the processor is congested.

Controlling a transmission rate of packet traffic

In particular embodiments, a monitoring processor may receive an interrupt from status monitoring logic associated with a monitored processor that has experienced an error. Interrupt logic at the monitoring processor may interrupt the monitored processor to initiate a standby mode of operation in the monitored processor. Core dump logic at the monitoring processor may retrieve a core dump from a memory associated with the monitored processor via a communication channel connecting the monitoring processor to the monitored processor or to the memory. Other embodiments are disclosed and claimed.
