摘要： Mechanisms for processing of communications between data processing devices are provided. With the mechanisms of the illustrative embodiments, a set of techniques that enables sustaining media speed by distributing transmit and receive-side processing over multiple processing cores is provided. In addition, these techniques also enable designing multi-threaded network interface controller (NIC) hardware that efficiently hides the latency of direct memory access (DMA) operations associated with data packet transfers over an input/output (I/O) bus. Multiple processing cores may operate concurrently using separate instances of a communication protocol stack and device drivers to process data packets for transmission with separate hardware implemented send queue managers in a network adapter processing these data packets for transmission. Multiple hardware receive packet processors in the network adapter may be used, along with a flow classification engine, to route received data packets to appropriate receive queues and processing cores for processing.

摘要： A network node that forwards traffic of a converged network received from a source end node receives a second message addressed to the network node, but intended for the source end node. The second message includes at least a portion of a first message originated by the source end node and previously forwarded by the network node. The network node extracts from the first message a source identifier of the source end node in a first communication protocol and determines by reference to a data structure a destination address of the second message in a second communication protocol. The network node modifies the second message to include the destination address and forwards the second message toward the source end node in accordance with the destination address.

摘要： Access control lists (ACLs) permit network administrators to manage network traffic flowing through a networking element to optimize network security, performance, quality of service (QoS), and the like. If a networking element has multiple ACLs directed towards different types of network optimization, each ACL may return a separate action set that identifies one or more actions the networking element should perform based on a received frame. In some cases, these action sets may conflict. To resolve the conflicts, a networking element may include resolution logic that selects one of the conflicting actions based on a predefined precedence value assigned to each action in an action set. By comparing the different precedence values, the resolution logic generates a new action set based on the actions with the highest precedence value.
