摘要： A method of scheduling the handling of communication channels by a processor assigned to handle a plurality of channels. The method includes determining for each channel, handled by the processor, a target time by which time it should receive processing, selecting one or more of the assigned channels whose data is to be handled next, based on the target times of the channels and when more than one channel is selected, choosing for handling before other channels, at least one of the selected channels based on a consideration directed at minimizing the average processing time of the channels.

摘要： A switch at a transmission end of a system including a number of memory devices defining queues for receiving traffic to be switched, each queue having an associated predetermined priority classification, and a processor for controlling the transmission of traffic from the queues. The processor transmits traffic from the higher priority queues before traffic from lower priority queues. The processor monitors the queues to determine whether traffic has arrived at a queue having a higher priority classification than the queue from which traffic is currently being transmitted. The processor suspends the current transmission after transmission of the current minimum transmittable element if traffic has arrived at a higher priority queue, transmits traffic from the higher priority queue, and then resumes the suspended transmission. At a receiving end, a switch that includes a processor separates the interleaved traffic into output queues for reassembly of individual traffic streams from the data stream.

摘要： A node (22) of a telecommunications network (2) receives, over a transmission chain (24) subject to packet jitter, packets of a connection involving a client device (26). The node (22) comprises a packet buffer (38) configured to store the packets received over the transmission chain prior to transmission of the packets to the client device (26). The node (22) further comprises a client-conscious scheduler (40) which is configured to schedule the transmission of the packets from the packet buffer (38) over a channel (32) to the client device (26) in accordance with a timing consideration of the client device (26). In an example embodiment, the timing consideration of the client device (26) which is taken into account by the scheduler (40) is avoidance of drain of a playout buffer of the client device.

摘要： A switch schedules guaranteed-bandwidth, low-jitter-traffic characterized by a guaranteed rate table (GRT) method. A rate matrix generated from collected provisioning information is decomposed into schedule tables by a low jitter (LJ) decomposition method. The LJ decomposition method imposes a set of constraints for the schedule tables: schedule tables are partial permutation matrices, weighted sum of the partial permutation matrices is greater than or equal to the weighted sum of the rate matrix, and each entry in the rate matrix belongs to one element of the LJ decomposition schedule matrices. An integer LJ decomposition programming problem is employed to generate the schedule tables that are scheduled for each time slot of the period of the switch. Schedule tables are selected in turn based upon selecting eligible tables having the earliest finishing time. If necessary, the rate matrix is updated prior to decomposition for a subsequent period.

摘要： A wireless broadband communications system and method that achieves reduced latency for high priority data when multiplexed with lower priority data for transmission over a TDD point-to-point radio link. The system prepares multiple data streams for transmission over a TDD radio link by buffering multiple data streams containing high and low priority packets in separate queues based upon their corresponding priority level. Each packet in the higher priority queues has a specified size, and a header defining the type of service provided and the packet destination. Next, the packets in the lower priority queues are fragmented to a reduced size based upon the data capacity of the link. The high priority packets and the fragmented, low priority packets are arranged in a sequence such that the high priority packets are transmitted first, and the low priority packets are transmitted when no data is buffered in any high priority queue.

摘要： A system and method for scheduling communications from a communication interface. Each of multiple send queues is associated with a destination and assigned to a logical communication channel. A list of stalled queues identifies those send queues for which a constraint restricts scheduling. When a queue is to be selected for service, a scheduler first attempts to find a member of the stalled queues list that is no longer stalled (e.g., any constraints were satisfied). Such a queue is selected for service if it exists. If there is no such queue, then all logical channels are examined and, from a list of send queues assigned to a selected logical channel, a send queue is selected for servicing. After a queue is scheduled from the stalled queues list, the list of queues assigned to its logical channel is adjusted (e.g., to place the queue at the tail of the list).
摘要翻译：一种用于从通信接口调度通信的系统和方法。多个发送队列中的每一个都与目的地相关联并分配给逻辑通信信道。停滞队列的列表标识约束限制调度的发送队列。当队列被选择用于服务时，调度器首先尝试找到不再停滞的停滞队列列表的成员（例如，满足任何约束）。如果存在这样的队列被选择用于服务。如果没有这样的队列，则检查所有逻辑信道，并且从分配给所选逻辑信道的发送队列的列表中选择发送队列进行维修。在从停滞的队列列表调度队列之后，调整分配给其逻辑信道的队列的列表（例如，将队列放置在列表的尾部）。
