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： 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： In a typical remote access application, such as access from the home to a packet-switched high speed network such as the Internet, the low-speed dial up connection to a network access is the main bottleneck in terms of the bandwidth and efficiency of transfer of data across the network access server. The present invention increases throughput through the network access server by identifying and dropping redundant, e.g., retransmitted, packets en route from the LAN or WAN to the remote terminal, thereby preserving precious bandwidth.

摘要： An election protocol or method is described for use in Internet Telephony, in which a gatekeeper is elected to serve as an active gatekeeper. The group of gatekeepers elect one gatekeeper in a zone to act as a primary gatekeeper that responds to gatekeeper request messages by broadcasting active gatekeeper claim messages that contain a unique gatekeeper priority value for the gatekeeper. The gatekeepers compare the received gatekeeper priority value with their own gatekeeper priority value and either broadcast another active gatekeeper claim message (if they are higher ranked) or do not broadcast another active gatekeeper claim message (if they are lower ranked). This process sorts the gatekeepers into a hierarchy with the highest ranked gatekeeper designated to respond to gatekeeper request messages. The other gatekeepers stand by in an idle mode and do not respond to gatekeeper requests. The other gatekeepers are ranked in priority in accordance with a gatekeeper priority value assigned to each gatekeeper. If the primary gatekeeper should go down (for example, due to either a graceful shutdown by a system administrator or due to a machine failure), a new gatekeeper is promoted to act as the primary gatekeeper based on the ranking of the gatekeepers, or the remaining gatekeepers can go through the iterative election process again.
摘要翻译：描述了在互联网电话中使用的选举协议或方法，其中选通守门员作为主动看门人。守门员组在一个区域中选出一名守门员，作为主要守门员，通过广播包含守门人唯一的守门人优先级值的主动守门人声明消息来响应关守请求消息。守门人将接收到的守门人优先级值与其自己的守门人优先级值进行比较，并且广播另一个主动看门人声明消息（如果它们排名较高），或者不广播另一个主动看门人声明消息（如果它们的排名较低）。该过程将守门人排序为具有指定为对守门员请求消息进行响应的排名最高的守门员的层次结构。其他看门人处于空闲模式，不响应守门人的请求。根据分配给每个守门员的守门人优先级值，其他看门人被优先排列。如果主要的守门员应该下台（例如，由于系统管理员的正常关机或由于机器故障而导致的），新的守门员被提升为基于守门人排名的主要守门人，或者剩下的看门人可以再次通过迭代选举过程。

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： 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： A method for coordinating and controlling multiple data streams representing a data transmission session that terminate in different termination units (such as network access servers). The data streams are transmitted over two or more links, collectively forming a "bundle". The termination units are linked together preferably over a local area network. One of the termination units that receives a data stream is designated as the termination unit to receive and reconstruct the call. The designated termination unit is the "owner" of the bundle. The termination unit broadcasts an advertisement consisting of a bundle mapping update packet software structure with an identification header to alert the other termination units that it is to reconstruct the call. The identification header in the advertisement notifies the other termination units that if they should receive a portion of the data stream in the bundle, they should forward their packets of data to the designated termination unit. The sharing of bundle information between the termination units gives a great deal of flexibility in the design and type of termination units that may be employed.
