    • Disclosed are apparatus and methods for managing upstream channels on a per cable modem basis. In certain embodiments, one or more thresholds are defined for each of a plurality of upstream logical channels of a headend system for receiving data from a plurality of cable modems (or other types of access nodes). Each defined threshold corresponds to a measurable parameter of the corresponding upstream logical channel. One or more metrics are collected for each cable modem of each upstream logical channel. It is determined whether to downgrade a selected cable modem to a selected one of the logical channels that has a lower performance level than the selected cable modem's current logical channel. Such downgrade determination is based on whether the selected cable modem's collected one or more metrics have failed a condition of the one or more defined thresholds and whether a percentage of a total of the cable modems of such current logical channel that have failed a condition for the one or more defined thresholds is less than a predefined percentage level. The selected cable modem is then caused to move from the current logical channel to the selected logical channel when the percentage of the total cable modems that have failed is below a predefined level if such selected logical channel is available. Otherwise, the current logical channel's modulation profile may be altered when the percentage of the total cable modems that have failed is above (or equal to) the predefined level.
    • 公开了用于在每个电缆调制解调器的基础上管理上游信道的装置和方法。 在某些实施例中,为头端系统的多个上游逻辑信道中的每一个定义一个或多个阈值,用于从多个有线调制解调器(或其他类型的接入节点)接收数据。 每个定义的阈值对应于相应的上游逻辑信道的可测量参数。 为每个上游逻辑信道的每个电缆调制解调器收集一个或多个度量。 确定是否将所选择的电缆调制解调器降级到具有比所选择的电缆调制解调器的当前逻辑信道更低的性能水平的所选逻辑信道中。 这种降级确定是基于所选择的电缆调制解调器收集的一个或多个度量是否已经失败了一个或多个定义的阈值的条件,以及是否已经失败了该条件的这种当前逻辑信道的电缆调制解调器的总和的百分比 一个或多个定义的阈值小于预定义的百分比水平。 当所选择的逻辑信道可用时,如果所有已故障的总电缆调制解调器的百分比低于预定义级别,则所选择的电缆调制解调器然后被引导从当前逻辑信道移动到所选择的逻辑信道。 否则,当已经发生故障的总电缆调制解调器的百分比高于(或等于)预定义电平时,当前逻辑信道的调制配置文件可能会被更改。
