Network devices with multiple fully isolated and independently resettable direct memory access channels and methods thereof

摘要

A method, computer readable medium, and system independently managing network applications within a network traffic management device communicating with networked clients and servers include monitoring with a network device a plurality of applications communicating over a plurality of direct memory access (DMA) channels established across a bus. The network device receives a request from a first application communicating over a first DMA channel in the plurality of DMA channels to restart the first DMA channel. In response to the request, the first DMA channel is disabled with the network device while allowing other executing applications in the plurality of applications to continue to communicate over other DMA channels in the plurality of DMA channels. A state of the first DMA channel is cleared independently from other DMA channels in the plurality of DMA channels, and communications for the first application over the first DMA channel are resumed with the network device.

1. A method for independently managing network applications, the method comprising:
monitoring, by a network traffic management device, a plurality of applications, each one of the plurality of applications communicating over a respective one of a plurality of direct memory access (DMA) channels established across a bus; disabling, by the network traffic management device, one DMA channel in the plurality of DMA channels in response to receiving an initial one of one or more sequential restart requests from one of the plurality of applications to restart the one DMA channel in the plurality of DMA channels, while allowing other executing applications in the plurality of applications to continue to communicate over other DMA channels in the plurality of DMA channels; determining, by the network traffic management device, when an elapsed time starting from each of the one or more sequential restart requests exceeds a threshold time before receipt of another subsequent one of the one or more sequential restart requests; clearing, by the network traffic management device, a state of the disabled DMA channel independently from the other DMA channels in the plurality of DMA channels when the determination indicates the elapsed time has exceeded the threshold time; and resuming, by the network traffic management device, communications for the one of the plurality of applications over the disabled DMA channel after the state of the disabled DMA channel is cleared.
