摘要： In one embodiment, a first ranging timing description describing at least a duration of time during which a subject cable modem (CM) may burst and a duration of time during which the subject CM and other CMs in a multiple access network are not permitted to burst is translated into a second ranging timing description describing a duration during which a burst from the subject CM is expected to be received by a cable modem termination system (CMTS). The CMTS is conditioned to receive a burst from the subject CM during the duration of time described by the second ranging timing description. A timing offset is determined from at least an actual time a burst from the subject CM is received by the CMTS and the duration of time during which the subject CM and other CMs in the multiple access network are not permitted to burst to produce a determined timing offset. The determined timing offset is reported to compensate for delay in the multiple access network and the subject CM.

摘要： In one embodiment, a Cable Modem Termination System (CMTS) generates a bandwidth grant message corresponding to a time segment. The CMTS identifies a portion of the time segment to be assigned according to received bandwidth request messages originating from downstream cable modems. The CMTS determines whether a remaining portion of the time segment can accommodate more than N broadcast contention slots, and if so, selects at least one of the cable modems for receiving an upstream bandwidth boost.

摘要： In one example, a Cable Modem Termination System (CMTS) sends first bandwidth allocation messages to a first upstream transmit interface on a cable modem and send second bandwidth allocation messages to a second upstream transmit interface on the cable modem. The bandwidth allocation messages indicate transmit windows for the cable modem to range over the interfaces. The transmit windows included in the first bandwidth allocation messages are spaced based on receipt of ranging requests from the second upstream transmit interface, and the transmit windows included in the second bandwidth allocation messages are spaced based on receipt of ranging requests from the first upstream transmit interface.

摘要： Users are enabled to network multiple customer premises equipment (CPE) devices together to form a virtual local area network (VLAN) among CPE devices that access the Internet through different cable modems. In a preferred embodiment, each VLAN is associated with a unique security association identifier (SAID), which enables a cable modem termination system (CMTS) to implement a secondary level of security in its routing procedures. As a result, data packets addressed to one or more members of a VLAN can be encrypted using the corresponding SAID such that access to the data packets is restricted only to members of the appropriate VLAN.
摘要翻译：用户能够将多个客户端设备（CPE）设备联网在一起，在通过不同的有线调制解调器访问互联网的CPE设备之间形成虚拟局域网（VLAN）。在优选实施例中，每个VLAN与唯一的安全关联标识符（SAID）相关联，其使电缆调制解调器终端系统（CMTS）在其路由过程中实现次级安全级别。因此，可以使用相应的SAID对寻址到VLAN的一个或多个成员的数据包进行加密，以使对数据包的访问仅限于适当VLAN的成员。
