摘要： A translation agent adapts DOCSIS information, primarily QoS information, for transmission over a PON. The agent places into an IP address field of a DHCP message the MAC address of an ONU associated with a CPE device attempting to register with a CMTS. The translation agent intercepts DHCP reply messages from the DHCP server using the MAC address of the ONU. The translation agent extracts information, including an IP address of the client CPE assigned by the DHCP server. The agent downloads a configuration file for the CPE device using the configuration filename and configuration file server contained in a DHCP reply message. Information contained in the configuration file is converted from content in a format used by DOCSIS, to content in a format used by PON devices. The translated content includes QoS parameters, functions related to which are controlled at the ONU by an OLT coupled to the CMTS.

摘要： A subscriber login server is used for managing a subscriber login session. The login server is associated with a DHCP server for configuring a premise equipment device and operator-managed device. A subscriber login client at the premise equipment device securely communicates login username and password identifiers to the subscriber login server without using PPP technology. The login server retrieves matching identifiers from a RADIUS server and authorizes service with messages to the DHCP server and the CMTS. The login client can emulate a PPP login client so that a user's interface is similar to a PPPoE client. However, a layer-3 CMTS can be used instead of a layer-2 CMTS. In addition, subscriber authentication and accounting using RADIUS are preserved, positive network access control at the CMTS is maintained, and native IP traffic is routed or switched for maximum performance and QoS treatment.

摘要： Systems and methods can provide for packet-rate policing and admission control with optional stress throttling. In some implementations, a broadband device can monitor bandwidth usage and respond after exceeding a maximum packet-rate threshold based on a per-channel basis. In other implementations, a broadband device can monitor bandwidth usage and respond after exceeding a maximum packet-rate threshold based on a per-service-flow basis. In additional implementations, a broadband device processor can feedback data to the packet-rate policer to throttle the packet rate based on processor utilization. Policing data traffic based on packet-rate instead of bandwidth can increase flexibility to service providers as an increasing number of services are deployed to users.

摘要： A flow bonder at a CMTS and another at a cable modem distribute packets of a service flow over multiple channels and collect them in the downstream direction respectively; vice versa in the upstream direction. The collector uses a service flow identifier and a sequence number identifier inserted by the distributor into each packet of the flow to reassemble the packets into the order they left the distributor. Packets received at the collector are stored to a buffer. If a stored packet is the next to be transmitted, it is transmitted. If not, the collector waits a predetermined period until the next packet to be sent is received. If it is not received during the wait period, the previously stored packet is sent. The wait period is based on the maximum transmission time difference between any two of the multiple channels.

摘要： Systems and methods can be used to provide reduced latency in channel changing for interactive programming. In some implementations, such systems and methods can include identifying a rapid channel change mode and filtering older requests when a device detects the rapid channel change mode. In other implementations, such systems and methods can predict channel change requests and identify predicted channels associated with the predicted requests. The predicted channels can thereby be requested in advance.

摘要： Leaky bucket state machines police packets and throttle packets of a stream or streams that are flowing from hosts towards the processor of a switch or router of a network. The throttling is performed by measuring and analyzing the actual flow rate(s) of the streams' packets. The actual flow rate(s) is compared to a predetermined threshold, which may be based on historical or estimated normal traffic patterns. If the actual flow rate exceeds the threshold associated with characteristics that relate packets to certain streams, packets are discarded from the streams having excessive flow rates. By discarding excessive packets having characteristics that correspond to packet information that typically causes a switch/router's processor to execute operations, the effects of a DoS attack are minimized while also minimizing the discarding of legitimate traffic packets.
摘要翻译：泄漏桶状态机将警报数据包和流量从主机流向网络交换机或路由器的处理器的流或节流包。通过测量和分析流的分组的实际流速来执行节流。将实际流量与预定阈值进行比较，其可以基于历史或估计的正常流量模式。如果实际流速超过与分组与特定流相关联的特性相关联的阈值，则从具有过大流量的流中丢弃分组。通过丢弃具有通常导致交换机/路由器的处理器执行操作的分组信息的特征的过多分组，DoS攻击的影响被最小化，同时最小化丢弃合法的流量分组。

摘要： A long-term usage profile and a congestion state metric are used to determine QoS treatment to apply to packets corresponding to a given network user. A user's historical long-term use, measured over one or more periods of time, is used to generate a profile that is compared to one or more predetermined usage threshold level(s). If the usage profile, either singular or composite corresponding to whether one or more than one measurement is used respectively, exceeds the threshold(s), QoS treatment is applied to service flow bytes according to the comparison results during times of network channel congestion. Congestion metrics are determined based on a count of the number of bytes dropped during a congestion measurement window. Either the count itself or the count rate of change combined with the count are compared to a congestion threshold. If the measured/derived values exceed a congestion threshold, the channel is deemed congested.
摘要翻译：使用长期使用配置文件和拥塞状态度量来确定应用于对应给定网络用户的分组的QoS处理。使用用户在一个或多个时间段内测量的历史长期使用来生成与一个或多个预定使用阈值水平进行比较的配置文件。如果分别使用与一个或多个测量相对应的单个或复合的使用情景模式超过阈值，则根据网络信道拥塞时的比较结果，对服务流字节应用QoS处理。基于在拥塞测量窗口期间丢弃的字节数的计数来确定拥塞度量。将计数本身或与计数相结合的计数变化率与拥塞阈值进行比较。如果测量/派生值超过拥塞阈值，则认为该信道拥塞。
