摘要： A supervisory communications node monitors and controls communications with a plurality of remote devices throughout a widely distributed network. A method is provided to convey and maintain information used to synchronize the packetization and burst operations within the network. During session setup, jitter constraints indirectly are used to explicitly communicate a synchronization timing reference. The timing reference is set at the beginning of a phase/period boundary used to service the session. In an embodiment, the announcement of the first grant is used as an explicit indication of the synchronization timing reference value. In another embodiment, the synchronization timing reference value is inferred if a remote device receives contiguous voice grants meeting certain conditions. In an embodiment implementing periodic scheduling, the actual arrival of the first grant is used to infer the synchronization timing reference value. In an embodiment, the present invention enables the synchronization timing reference value and/or the periodicity to be modified if network conditions indicate that packetization and burst operations are out-of-synchronization.

摘要： A system for reducing the bandwidth required to transmit a data packet via a wireless network is provided. In an embodiment, the system is configured for generating a packet to be transmitted via the wireless network. Once a packet is generated, a packet type of the packet to be transmitted via the wireless network is determined. Based on the packet type, a suppression rule is selectively applied to the packet to generate a suppressed packet. Applying the suppression rule includes suppressing at least a portion of the header of the packet and adding a descriptor associated with the header suppression rule to the packet. The system is configured to conclude with the transmittal of the suppressed packet via the wireless network.

摘要： A system and method is provided for scheduling transmissions from a plurality of services operating over a widely distributed communications network. A headend communications device (such as a cable modem termination system) arbitrates bandwidth among a plurality of cable modems configurable for bi-directional communications. The headend grants a bandwidth region to a specified cable modem or assigns contention regions for a group of cable modems. Each cable modem contains a local scheduler that sends requests for bandwidth according to local policies or rules. Upon receipt of a grant from the headend, the local scheduler selects packets to be transmitted to best serve the needs of the services associated with the cable modem. Accordingly, a service requesting bandwidth may not be the service utilizing the grant corresponding to bandwidth request. Nonetheless, the local scheduler manages bandwidth allocation among its local services such that all requesting services eventually receive bandwidth
摘要翻译：提供了一种用于调度来自在广泛分布的通信网络上操作的多个服务的传输的系统和方法。头端通信设备（例如电缆调制解调器终端系统）在可配置为双向通信的多个电缆调制解调器之间仲裁带宽。前端向指定的电缆调制解调器授予带宽区域，或为一组电缆调制解调器分配争用区域。每个电缆调制解调器包含根据本地策略或规则发送带宽请求的本地调度器。在从头端接收到授权时，本地调度器选择要发送的分组以最好地满足与电缆调制解调器相关联的服务的需要。因此，请求带宽的服务可能不是利用与带宽请求相对应的授权的服务。然而，本地调度器管理其本地服务之间的带宽分配，使得所有请求服务最终接收带宽

摘要： A system, method, and computer program product for synchronizing time between a centralized controller device and at least one subscriber device on a fiber access network. The control layer of a network device is expanded, and additional messaging control is added via the transmission of data frames. The expansion prevents reliance on a physical layer signal. The time synchronization also allows a time stamp to be incorporated into a message. Thus, bandwidth is not wasted by simply transmitting a time stamp by itself. In an embodiment, the centralized controller device measures the time difference between the time at which a particular ranging request is transmitted and the time at which the particular ranging request is received. The time difference represents the time adjustment value for the particular subscriber device and allows the device to synchronize its time with that of the centralized controller device.
摘要翻译：一种用于在中央控制器设备与光纤接入网络上的至少一个用户设备之间同步时间的系统，方法和计算机程序产品。网络设备的控制层被扩展，并且经由数据帧的传输来添加额外的消息收发控制。扩展防止对物理层信号的依赖。时间同步还允许将时间戳合并到消息中。因此，仅通过简单地发送时间戳就不会浪费带宽。在一个实施例中，集中控制器设备测量发送特定测距请求的时间与接收到特定测距请求的时间之间的时间差。时差表示特定用户设备的时间调整值，并允许设备将其时间与集中控制器设备的时间同步。
