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.

摘要： A method and system for efficient direct DMA for processing connection state information or other expediting data packets. One example is the use of a network interface controller to buffer TCP type data packets that may contain connection state information. The connection state information is extracted from a received packet. The connection state information is stored in a special DMA descriptor that is stored in a ring buffer area of a buffer memory that is accessible by a host processor when an interrupt signal is received. The packet is then discarded. The host processor accesses the ring buffer memory only to retrieve the stored connection state information from the DMA descriptor without having to access a packet buffer area in the memory.

摘要： A method, computer readable medium, and a system for communicating with networked clients and servers through a network device includes establishing a plurality of direct memory access (DMA) channels across a host system bus over which a plurality of executing applications each having a respective application driver communicate with a network through a network device configured to receive and transmit network data packets. At a first port in the network device, a first network data packet destined for an executing application is received. A first DMA channel over which to transmit the first network data packet towards the destined executing application is identified, and the first network data packet is transmitted to the destination executing application over the designated DMA channel mapping to the first port.

摘要： A programmable packet switching controller has a packet buffer, a pattern match module, a programmable packet classification engine and an application engine. The packet buffer stores inbound packets, and includes a header data extractor to extract header data from the inbound packets and to store the extracted header data in a header data cache. The header data extractor also generates a header data cache index and provides it to the packet classification engine for it to retrieve the extracted header data. The packet classification engine has a decision tree-based classification logic for classifying a packet. Each of the leaves of the tree represents a packet classification. The packet classification engine uses the header data cache index to retrieve the header data to perform multiple header checks, starting at a root of the tree and traversing branches until a leaf has been reached. The application engine has a number of programmable sub-engines arrayed in a pipelined architecture. The packet classification engine provides start indicators based on the packet classification to the programmable sub-engines to identify application programs to be executed. The sub-engines includes a source lookup engine, a destination lookup engine and a disposition engine, which are used to make a disposition decision for the inbound packets in a processing pipeline. The pattern match module is used to compare the packet to a pre-defined pattern in order to provide a disposition recommendation.
