摘要： A token bucket instantiation regulate packets in a traffic flow stream based on a predetermined peak traffic flow rate. The token bucket size is nominally set to zero. An evaluation is made at a device that has received a given packet. The packet is considered conforming and is passed from the device if the token depth of the bucket is zero or greater. The token depth is decreased by the number of byes in the packet that was passed. The token depth is continuously replenished at a predetermined token rate until the predetermined bucket size is attained (the bucket is full). A received packet is deemed nonconforming if the token depth is less than zero; the non-conforming packet is not passed but is processed according to non-conforming criteria. Token bucket instantiations may be implemented in hardware, software or firmware for each traffic flow to regulate traffic to a given user.

摘要： A DOCSIS set-top gateway device uses multiple embedded cable modems so that one eCM can remained tuned to a frequency being used for a current two-way data session and another eCM can be used to tune to a different frequency. The other eCM that tunes to a different frequency is disabled from operating in the upstream direction to avoid conflict with the two-way eCM in communicating with a CMTS.The eCMs in the DSG are controlled by a client controller that interfaces applications local to the DSG to a central device, such as a CMTS. A message may be sent to a client application requesting content on a traffic flow using a different frequency than the two-way capable sCM. The client controller instructs the upstream-disabled eCM to tune to the different frequency, meanwhile the two-way eCM stays tuned to the current frequency.

摘要： A device, such as a cable modem or embedded media terminal adaptor that attempts to obtain unauthorized network services, is designated by head end equipment, such as a CMTS, as being a ‘rogue’ device. Upon an initial range request from the rogue device, the CMTS responds with a continuing range command. Upon receiving each periodic range request transmitted from the rogue device during a periodic station maintenance opportunity, the CMTS responds with another continuing range command. Thus, the rogue device does not ever establish connection with the CMTS because an ACK message is not received back from the CMTS. Moreover, use of CMTS resources for processing request from rogue devices is minimized because the rogue device does not reinitialize its MAC after a predetermined period of time, which it would do if a periodic ranging opportunity was not scheduled.
摘要翻译：设备，例如电缆调制解调器或者试图获得未经授权的网络服务的嵌入式媒体终端适配器，由头端设备（如CMTS）指定为流氓设备。在来自流氓设备的初始范围请求时，CMTS以持续范围命令作出响应。在接收到在周期性站维护机会期间从流氓设备发送的每个周期性范围请求时，CMTS响应另一连续范围命令。因此，流氓设备不会与CMTS建立连接，因为没有从CMTS接收到ACK消息。此外，由于流氓设备在预定的时间段之后不重新初始化其MAC，所以使用CMTS资源来处理来自流氓设备的请求被最小化，如果没有安排定期的测距机会，它将会做。

摘要： Different polling rates are applied to high priority BE service flows depending on whether the service flow contains, or is about to contain, traffic packets. A high priority service flow is identified upon boot-up of a user device, and defaults to a slow polling mode. A trigger causes the service flow to be serviced as a fast polling mode. The fast polling mode lasts for a predetermined period of time. If traffic continues at the end of the predetermined period of time, the predetermined period of time is reset so that the fast-polling mode continues until traffic flow on the high priority service flow ceases.
摘要翻译：取决于业务流是否包含或将要包含业务分组，不同的轮询速率被应用于高优先级BE业务流。在用户设备启动时识别出优先级高的服务流，并且默认为慢速轮询模式。触发器使得服务流被服务为快速轮询模式。快速轮询模式持续一段预定的时间。如果业务在预定时间段结束时继续，则预定时间段被重置，使得快速轮询模式持续，直到高优先级业务流程的业务流量停止。

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.
摘要翻译：用户登录服务器用于管理用户登录会话。登录服务器与DHCP服务器相关联，用于配置前提设备设备和操作员管理的设备。住宅设备设备上的用户登录客户端可以安全地将登录用户名和密码标识符传递给用户登录服务器，而无需使用PPP技术。登录服务器从RADIUS服务器检索匹配的标识符，并向DHCP服务器和CMTS授权服务。登录客户端可以模拟PPP登录客户端，使用户的界面类似于PPPoE客户端。然而，可以使用第3层CMTS而不是第2层CMTS。另外，保留了使用RADIUS的用户认证和计费，保持了CMTS的正确的网络访问控制，本地IP流量被路由或切换，以实现最佳性能和QoS处理。
