摘要： A method and system for dynamic service registration, activation and deactivation on a data-over-cable system. A first network device, such as a cable modem with associated service devices (e.g., Voice over Internet Protocol telephones) sends a first message to another network device, such as a cable modem termination system. The first message includes multiple service parameters for a desired service requested by a service device associated with the first network device. The multiple service parameters are extracted from the first message. A service session profile is created for the desired service. The service session profile includes one or more of the extracted service parameters required by the desired service. The service session profile is used by a service server associated with the cable modem termination system to provide a desired service. The service session profile is associated with a deferred inactive service identifier for the cable modem. The deferred inactive service identifier is returned to the cable modem in a second message. The deferred inactive service identifier is used at a later time by a service device associated with the cable modem to activate the desired service and to generate a service event on a service server. The service event may include an authentication, authorization, accounting or other event. A deferred service can be activated and deactivated used even after a network device, such as a cable modem, has already established a session with another network device, such as a cable modem termination system, on a data-over-cable system.

摘要： In one embodiment, an apparatus cascades groups of serialized data streams through devices, and performs operations based on information communicated therein. A received group of serialized data streams is aligned, but not framed, and forwarded to a next device (e.g., a next stage in a linear or tree cascaded formation of devices). Eliminating the framing and subsequent serialization operations performed on the received group of serialized data streams reduces the latency of communications through the cascaded devices, which can be significant when considered in relation to the high-speed communication rates. The received group of serialized data streams is also framed to create a sequence of data frames for processing (e.g., associative memory lookup operations, controlling multiplexing of received downstream serialized data streams, general or other processing) within the device.

摘要： Tones that are generated by a telephone or PC (such as DTMF tones) and subject to loss or noise during generation or during transmission along a medium are detected and replaced with substantially noise-free and distortionless digital signals. In one embodiment, the replacement of the tones is done in a modem embodied in an Internet telephony Gateway/Terminal, such as in a network access server coupling a time division multiplexed telephone line to a packet-switched network. The replacement of the tones may also be performed in any suitable device that provides an interface between a time division multiplexed transmission medium and a packet switched data network, such as in the modems of a cellular telephone network to Internet network access server.

摘要： A network access server providing remote access to an IP network for a remote client initiates a PPP connection for a remote client quickly, and without requiring re-negotiation of Link Control Protocols and Network Control Protocols. The network access server has a PPP session with the remote client go dormant, for example when the user is a wireless user and goes out of range of a radio tower and associated base station. The network access server does not get rid of the PPP state for the dormant session, but rather switches that PPP state to a new session, such as when the client moves into range of a different radio tower and associated base station and initiates a new active session on the interface to the wireless network. The switching of PPP states may be within a single network access server, or from one network access server to another. This “context switching” of the active PPP session allows the mobile user to seamlessly move about the wireless network without having to re-negotiate Link Control Protocols and Network Control Protocols every time they move out of range of one radio tower and into range of another radio tower.
摘要翻译：为远程客户端提供远程访问IP网络的网络访问服务器可以快速启动远程客户端的PPP连接，而无需重新协商链路控制协议和网络控制协议。网络接入服务器与远程客户端进行PPP会话休眠，例如当用户是无线用户并超出无线电塔和相关基站的范围时。网络访问服务器不能摆脱休眠会话的PPP状态，而是将PPP状态切换到新会话，例如当客户端移动到不同无线电塔和相关联的基站的范围内并启动新的活动会话在无线网络的接口。 PPP状态的切换可以在单个网络接入服务器内，或者从一个网络接入服务器到另一个。有源PPP会话的这种“上下文切换”允许移动用户无缝地移动无线网络，而不必在每次移动超出一个无线电塔的范围并进入另一个无线电塔的范围时重新协商链路控制协议和网络控制协议无线电塔。

摘要： Two network entities allocate the performance of encryption and compression algorithms amongst each other in a controlled and coordinated manner so as to avoid unnecessary duplication of encryption and compression at different protocol layers and an associated waste of CPU power. For example, a first network entity performs both encryption and compression at the IP layer, and instructs the second network entity to disable PPP-layer encryption and compression. In a wireless networking example of the invention, the first network entity is a home agent (e.g., a router) for a wireless communications device and the second network entity is a foreign agent (e.g., a network access server) providing network access for the communications device. The foreign agent terminates a Point-to-Point Protocol (PPP) session with the communications device, but implements (or does not implement) PPP-layer compression and encryption algorithms under the supervision and control of the home agent.
摘要翻译：两个网络实体以受控和协调的方式分配加密和压缩算法的性能，以避免不同协议层的加密和压缩的不必要的重复以及CPU功率的相关浪费。例如，第一网络实体在IP层执行加密和压缩，并指示第二网络实体禁用PPP层加密和压缩。在本发明的无线网络示例中，第一网络实体是用于无线通信设备的归属代理（例如，路由器），并且第二网络实体是提供网络接入的外部代理（例如，网络接入服务器）通信设备。外部代理终止与通信设备的点对点协议（PPP）会话，但在归属代理的监督和控制下实现（或不实现）PPP层压缩和加密算法。

摘要： A mobile Internet Protocol service provider system implements home agent functionality in two separate devices. One device, the home registration agent, is devoted to registration of the mobile node and session control. The other device, the home tunneling agent, is devoted to tunneling and routing functions for the foreign agent. The home registration agent can be a general purpose computer. The home tunneling agent is preferably implemented in a robust routing device, such as an IP switch or router. Multiple home tunneling agents or home registration agents can be implemented in the respective devices as multiple instantiations of a home registration agent or home tunneling agent software program.Foreign agent functionality for mobile IP networking can also be split into separate devices. In a preferred embodiment, a foreign registration agent handles session control and registration traffic with the home registration agent, and a foreign tunneling agent provides packet capsulation/decapsulation and routing services for the mobile node and exchanging data traffic with the home tunneling agent.

摘要： In a Quality of Service system, segments in a TCP session are assigned a priority level. A segment may contain an acknowledgement and data. The system determines if network congestion is detected or anticipated in the segment's priority band or in a higher priority band. When the TCP segment arrives at a network point, the segment is split into an acknowledgement segment and a data segment. The acknowledgement segment is scheduled at a higher QoS priority than the data segment.

摘要： Multiple home agents for a home agent service provider network are implemented in a single computing platform in software as multiple virtual home agents. Each home agent is assigned or dedicated to a single virtual private network. Any number of home agents can be realized in the computing platform by multiple instantiations of a home agent program or code, and by providing unique IP addresses for each instantiation. Each home agent runs independently, and is independently configured and managed by the subscriber of the virtual private network service, freeing the service provider of having to manage and supervise low level processing tasks and customization features that the subscribers may want. In a representative embodiment, the computing platform comprises a router having a general purpose-computing platform.

摘要： A method of finding a mobile wireless communications device when an Internet Protocol (IP) packet from a remote user is sent to the device over an IP network. The mobile device does not have to register with the IP network in order to receive the IP. The method comprises the steps of receiving the IP packet at a home agent associated with a wireless communications network. The IP packet includes an IP address assigned to the device. If there is no current mobility binding record for the mobile device, instead of dropping the packet the home agent sends an access-request packet, containing the IP address, to an authentication server. The authentication server, e.g., a RADIUS server, maintains a table mapping the IP address for the device to an identification number uniquely associated with the device, such as the device's International Mobile Subscriber Identity number. The authentication server sends an access-accept packet to the home agent in the event that the device is authorized to receive the IP packet, in which case the access-accept packet includes the identification information. The home agent uses the identification number to locate, page and automatically connect the wireless device to the IP network via an InterWorking Unit (IWU) configured as a IP network access server.
