Abstract: A system for lossless switching of traffic in a network device may be implemented when a network switch is integrated into a gateway device, or with any other data source. A processor of the gateway device may receive queue depth information for queues of the network switch. The processor may prevent data from being transmitted to congested queues of the network switch, while allowing data to be transmitted to uncongested queues. In this manner, data loss can be avoided through the network switch for data sourced from the gateway device, such as audio-video data retrieved from a hard drive, audio-video data received from a tuner, etc. Furthermore, re-transmission at higher layers can be reduced. Since the subject system observes congestion for each individual queue, only traffic destined to that particular, congested, queue is affected, e.g. paused. Traffic to non-congested queues is not affected, regardless of traffic class or egress port.

Abstract: A system for enhanced resource utilization includes a network interface with access to memory of a device, in communication with an operating system of the device. The system receives, from the operating system, an identification of a predetermined amount of the memory for a packet buffer, store multiple packets in the allocated memory. A total size of the multiple packets is smaller than or equal to the predetermined amount of memory. The system generates a status record for each received packet stored in the allocated memory, and stores the generated status records in the allocated memory. The system also allocates a socket buffer for each packet stored in the allocated memory such that the socket buffer has reference to the corresponding packet in the allocated memory.
