A first memory device stores (i) a head part of a FIFO queue structured as a linked list (LL) of LL elements arranged in an order in which the LL elements were added to the FIFO queue and (ii) a tail part of the FIFO queue. A second memory device stores a middle part of the FIFO queue, the middle part comprising a LL elements following, in an order, the head part and preceding, in the order, the tail part. A queue controller retrieves LL elements in the head part from the first memory device, moves LL elements in the middle part from the second memory device to the head part in the first memory device prior to the head part becoming empty, and updates LL parameters corresponding to the moved LL elements to indicate storage of the moved LL elements changing from the second memory device to the first memory device.

A network device includes an antenna connected to an RF chip and a processor coupled to an Ethernet port, the RF chip, a program memory, a packet buffer memory, a pointer buffer memory, and a program memory. The program memory contains instruction that, when executed by the processor, cause a plurality of packets received by the antenna and the RF chip in a first order to be stored in the packet buffer memory in such order, cause a pointer associated with each one of the plurality of packets to be stored in the pointer buffer memory, cause the pointers stored in the pointer buffer memory to be placed in a second order in accordance with a timestamp that is included with each packet, cause the packets stored in the packet buffer memory to be passed along to the Ethernet port in accordance with the sorted pointer to each packet.

A system and method can support packet switching in a network environment. The system can include an ingress buffer on a networking device, wherein the ingress buffer, which includes one or more virtual output queues, operate to store one or more incoming packets that are received at an input port on the networking device. Furthermore, the system can include a packet flush engine, which is associated with the ingress buffer, wherein said packet flush engine operates to flush a packet that is stored in a said virtual output queue in the ingress buffer, and notify one or more output schedulers that the packet is flushed, wherein each output scheduler is associated with an output port.

An apparatus for managing data queues is disclosed. The apparatus includes at least one sensor for collecting data, a data interface for receiving data from the sensor(s) and for placing the collected data in a set of data queues, and a priority sieve for organizing the set of data queues according to data priority of a specific task. The priority sieve includes a scoreboard for identifying queue priority and a system timer for synchronization.

A system, apparatus, and methods are provided that support the passing of oversized messages within a publish-subscribe messaging system. During operation, the system subscribes to a message stream brokered by a message brokering cluster that imposes a maximum message size. Responsive to receiving a given message of the message stream, the system (1) determines an offset to commit to the message brokering cluster, wherein the determined offset is based on whether one or more segments of one or more oversized messages are buffered, and (2) commits the determined offset to the message brokering cluster. Responsive to recovering from a crash, wherein the offset at which to resume the receipt of messages from the message stream is unknown, the system then retrieves the determined offset from the message brokering cluster and resumes the receipt of messages from the message brokering cluster based on the determined offset.

Methods and systems for a more efficient transmission of network traffic are provided. According to one embodiment, presence of outbound payload data, distributed across a first and second payload buffer, within a user memory space of a network device that has been generated by a user process is determined by a bus/memory interface or a network interface unit. The payload data is fetched by performing direct virtual memory addressing of the user memory space including mapping virtual addresses of the payload buffers to corresponding physical addresses, including: (i) when the payload buffers are noncontiguous, then retrieving the outbound payload data with reference to multiple buffer descriptors having starting virtual addresses of the payload buffers and (ii) when they are contiguous, then retrieving the outbound payload data with reference to a single buffer descriptor. The outbound payload data is then segmented across one or more TCP packets.

One or more wireless communication systems may coexist at about the same geographical location and be configured to access the same radio channel. The coexistence of these systems may cause collisions and degrade throughput. Although countermeasures, such as reserving airtime with a resource assignment, may be taken to avoid collisions, these countermeasures are degrading throughput as well. The reserved airtime is reduced by adding a start time to the resource assignment. The reduced airtime may be used by others for performing a transmission, thus increasing the throughput and efficiency of the access to the radio channel.

The present application provides a channel type used to support user QoE expectations, which is, in particular, a QoS and QoE guaranteed channel (QQGC). Also provided is a related method and system for providing a QQGC. Effective bit rate (EBR), average bit rate, and maximum bit rate, are determined and used to support the channel. The EBR can be determined based on QoE reports. An application function, such as a network data analytics function provides the indication of effective bit rate. One or more portions of the application function can be provided in potentially different locations of a communications network and operatively coupled. Alternatively, application function portions can be co-located. The EBR is provided to and used by devices in the network to reserve user plane resources to support data flows at the EBR. The EBR can also be used for admission or rejection of requests for a QQGC channel.

When packet loss is detected during a communication session, a current interactivity mode is checked to determine whether to increase the amount of received audio data stored in a buffer of the receiving device. If the current interactivity mode indicates a low level of interactivity between participants in the communication session, then the total amount of received audio data stored in the buffer is increased, in order to increase the delay between receipt of audio data by the electronic device, and outputting of the audio data by the electronic device. The increased output delay is then used to recover lost packets, so that audio quality is increased while the level of interactivity between participants is low. When the current interactivity mode subsequently indicates higher participant interactivity, the amount of received audio data stored in the buffer may be reduced.

A method for buffer load management in a communication device includes storing in a first buffer of the communication device, multimedia data comprised in data packets, determining an indication of the input rate at that first buffer and adding the indication to a second buffer containing information on the input rate over time, performing an autocorrelation on a signal comprising said information on the input rate over time, finding peaks in the autocorrelation and identifying a peak in a period to perform for the peak, a crosscorrelation of the signal comprising the information on the input rate over time with a periodic signal with given phase, selecting a part of the information on the input rate stored in the second buffer, using a reference signal, determining a target latency for the first buffer, and applying the target latency to the first buffer.
