摘要： Aspects of the present disclosure provide various apparatuses and methods of reordering DRB flow packets using an in-band solution to reduce delay due to data packet buffering in head-of-line blocking scenarios across multiple DRB flows. When a packet of a flow is lost or not received, other flows carried in the same DRB can forward later received packets without waiting for the missing packet to be retransmitted and received.

摘要： Methods and apparatus for processing and using TCP packets to communicate RTP packets are described. Head of line blocking is avoided by operating a TCP packet processing module to output RTP packet data to an application irrespective of whether or not a preceding TCP packet was received. Since output of packet data to an application using RTP packets is not delayed when there is a missing TCP packet, head of line blocking is avoided. RTP packet data is subjected to pattern matching in order to identify and process RTP packets in the case where RTP header information such as packet length information is missing due to the failure to receive a TCP packet. The methods are particularly well suited for the communication of audio and/or video by devices operating behind firewalls which block UDP or other types of packets other than TCP packets.
摘要翻译：描述了处理和使用TCP分组来传送RTP分组的方法和装置。通过操作TCP分组处理模块来将RTP分组数据输出到应用来避免线路阻塞的头部，而不管先前的TCP分组是否被接收。由于当存在丢失的TCP分组时，使用RTP分组的分组数据的输出不被延迟，所以避免了线路阻塞。在RTP报头信息如分组长度信息由于不能接收TCP分组而丢失的情况下，RTP分组数据经受模式匹配以便识别和处理RTP分组。这些方法特别适用于在阻塞UDP或除TCP数据包之外的其他类型的数据包的防火墙之后运行的设备进行音频和/或视频的通信。

摘要： Aspects disclosed in the detailed description include head-of-line blocking (HOLB) mitigation in communication devices. Output queues employed by a communication device for transmitting data are susceptible to HOLB. In this regard, in one aspect, a queue monitoring logic is configured to detect HOLB by measuring and comparing a depth(s) of an output queue(s) against a queue-overflow threshold. If the depth(s) of the output queue(s) exceeds the queue-overflow threshold, a queue weight(s) of a corresponding input queue(s) is decreased to reduce data flow into the output queue(s), thus mitigating the HOLB in the output queue(s). In another aspect, the queue monitoring logic is configured to detect queue depletion by comparing the depth(s) of the output queue(s) against a queue-depletion threshold. By mitigating the HOLB and the data starvation in the output queue(s), it is possible to optimize the output queue(s) to achieve higher throughput and data integrity with lower power consumption.
摘要翻译：在详细描述中公开的方面包括通信设备中的行前阻止（HOLB）抑制。用于传输数据的通信设备使用的输出队列易受HOLB的影响。在这方面，在一方面，队列监视逻辑被配置为通过测量和比较输出队列的深度与队列溢出阈值来检测HOLB。如果输出队列的深度超过队列溢出阈值，则减少对应输入队列的队列权重以减少进入输出队列的数据流，从而减轻输出队列中的HOLB。在另一方面，队列监视逻辑被配置为通过将输出队列的深度与队列耗尽阈值进行比较来检测队列耗尽。通过减轻输出队列中的HOLB和数据不足，可以优化输出队列，以便以更低的功耗实现更高的吞吐量和数据完整性。

摘要： There is provided a method in a packet based network system for node-to-node transmission of data packets comprising timing packets and non-timing packets, which is directed to a mechanism for providing a delay variation compensation in a timing system or timing sensitive signal transport in a packet based network without participating in the timing signaling of the timing packets or timing sensitive packets themselves. The method comprises associating the data packets with different levels of transmission priority Pr, Pl, assigning highest (or highest available) transmission priority Pr to the timing packets, separately queuing the timing packets in different buffers 401, 402, and providing first opportunity transmission of the timing packets regardless of transmission priority level of non-timing packets waiting to be transmitted. The advantage of the method is that timing-sensitive traffic thereby experiences reduced buffer delay variations.

摘要： The disclosed embodiments provide a system that operates a switch fabric. During operation, the system creates a set of virtual links for a first set of physical ports in the switch fabric. Next, the system uses a set of virtual port numbers to create a set of mappings between the set of virtual links and a second set of physical ports in the switch fabric, wherein the second set of physical ports is connected to the first set of physical ports using a single physical link. The system then uses the mappings to provide non-blocking behavior in traffic from the first set of physical ports to the second set of physical ports.

摘要： A group of low-level FIFOs may be logically bound together to form a super-FIFO. The super-FIFO may treat each low-level FIFO as a storage location. The super-FIFO may enable a push to (or a pop from) every low-level FIFO, simultaneously. The super-FIFO may enable a virtual channel (VC) to use the super-FIFO, bypassing a VC FIFO for the VC, removing several cycles of latency otherwise needed for enqueuing and dequeuing messages in the VC FIFO. In addition, the super-FIFO may enable bypassing of an arbiter, further reducing latency by avoiding a penalty of the arbiter.

摘要： A method includes receiving a first packet at an input of a switching device and determining whether to insert first data associated with the first packet into a normal buffer of the input. The determination of whether to insert first data associated with the first packet into the normal buffer includes determining whether the first output identifier matches a second output identifier corresponding to second data in the normal buffer that is associated with a second packet. The first data is inserted into the normal buffer when the first output identifier matches the second output identifier.

摘要： A plurality of SMP modules and an IOP module communicate storage traffic via respective corresponding I/O controllers coupled to respective physical ports of a switch fabric by addressing cells to physical port addresses corresponding to the physical ports. One of the SMPs executes initiator software to partially manage the storage traffic and the IOP executes target software to partially manage the storage traffic. Storage controllers are coupled to the IOP, enabling communication with storage devices, such as disk drives, tape drives, and/or networks of same. Respective network identification registers are included in each of the I/O controller corresponding to the SMP executing the initiator software and the I/O controller corresponding to the IOP. Transport of the storage traffic in accordance with a particular VLAN is enabled by writing a same particular value into each of the network identification registers.
