摘要： Method and apparatus of establishing an L2TP tunnel. A routing device of a first IP network is coupled to a public network and a routing device of the second private IP network is coupled to the public network. An L2TP tunnel is initiated and an IP address from an address space of the first private IP network is provided. An L2TP tunnel is maintained between the routing device of the first IP network and the routing device of the second private IP network. Data traffic is tunneled between the first and the second IP network over the public network via the L2TP tunnel. A control mechanism is utilized for providing L2TP tunnel traffic error correction.

摘要： A system for automatically populating an IP telephony address mapper with mapping information for an IP telephony gateway or other device. A self-registering gateway is configured to automatically provide an address mapper with mapping indicia defining the IP address of the gateway and the telephone numbers served by the gateway. In one embodiment, for instance, the gateway places a PSTN modem-to-modem call to the address mapper and conveys its IP address as a modulated data stream, while the address mapper may determine the telephone number of the gateway through established automatic calling number delivery procedures. Based on the telephone number of the gateway, the address mapper may then refer to a telephone number mapping database to identify other telephone numbers that could be served by the gateway. The address mapper may then update its address mapping data files accordingly.

摘要： A method and system for distributed network address translation for mobile network devices. A mobile network device requests one or more locally-unique ports with a Port Allocation Protocol from a second network device on a first network to identify the first network device on the first network if the mobile first network device roams to a second external network. One or more default or ephemeral ports on the mobile network device are replaced with one or more locally-unique ports obtained with the Port Allocation Protocol. The one or more locally-unique ports allow distributed network address translation to be used with the mobile network device. A combination network address is created for the mobile network device with a locally unique port and an external network address for the first network to identify the mobile first network device if the mobile first network device roams to a second external network.

摘要： A high-fidelity voice/audio communication system including a high-fidelity SLIC (HSLIC) device that combines traditional BORSCHT functionality with high fidelity sampling and compression techniques. The HSLIC preferably resides on a single plug-in line card contained within a multi-cards chassis. The line card includes an analog interface that connects to a two-wire subscriber line, a high fidelity codec for sampling the analog signal at a high resolution and converting high rate digital signals to an analog signal, a voice processing client running on a microprocessor and associated digital memory. The high fidelity codec preferably has a sample rate of at least twenty thousand samples per second, and no less that 250 quantization levels. The voice processing client preferably includes an Internet Protocol (IP) processing client, Session Initiation Protocol (SIP) client, a Real Time Protocol (RTP) client, and other components of a communication protocol stack for establishing a connection over a packet based network by way of the network interface circuit. The line card establishes a high fidelity audio connection by sending an invite request to a proxy server; receiving an okay signal indicating that the request was received; sending an acknowledge signal; quantizing audio information at a sampling rate greater than twenty thousand samples per second with a resolution of no less than 4096 quantization levels; and, packetizing the quantized data for transmission to a remote device.

摘要： A system for user-space packet modification, including a set of kernel code and a user-level application programming interface (API). The system facilitates creation of a special socket for passing packets between kernel space and user space. The system in turn facilitates creation and application of a packet filter associated with the socket, in order to trap incoming or outgoing packets being processed in the kernel at a designated point in a protocol stack. Once a packet is trapped, it is moved through the socket into user space, thereby at least temporarily preventing the protocol stack from further processing the packet. In user space, an application may operate on the packet, for instance, modifying aspects of the packet or deleting the packet altogether. The system in turn facilitates injection of a packet from user space into kernel space, and into a designated point in the protocol stack for desired stack processing.
摘要翻译：用于用户空间分组修改的系统，包括一组内核代码和用户级应用程序编程接口（API）。该系统有助于创建一个特殊的套接字，用于在内核空间和用户空间之间传递数据包。该系统又促进了与套接字相关联的分组过滤器的创建和应用，以便在协议栈中的指定点捕获在内核中正在处理的进入或传出的分组。一旦数据包被捕获，它将通过套接字移动到用户空间中，从而至少暂时防止协议栈进一步处理数据包。在用户空间中，应用可以对分组进行操作，例如，修改分组的方面或完全删除分组。该系统又有助于将分组从用户空间注入到内核空间中，并且进入协议栈中的指定点以进行所需的堆栈处理。

摘要： A computationally simple yet powerful forward error correction code scheme for transmission of real-time media signals, such as digitized voice, video or audio, in a packet switched network such as the Internet. An encoder at the sending end derives p redundancy blocks from each group of a k payload blocks and concatenates the redundancy blocks, respectively, with payload blocks in the next group of k payload blocks. At the receiving end, a decoder may recover up to p missing packets in a group of k packets, provided with the p redundancy blocks carried by the next group of k packets. The invention thereby enables correction from the loss of multiple packets in a row, without significantly increasing the data rate or otherwise delaying transmission.
摘要翻译：一种用于在诸如因特网的分组交换网络中传输诸如数字化语音，视频或音频的实时媒体信号的计算简单而强大的前向纠错码方案。发送端的编码器从k个有效载荷块的每组中导出p个冗余块，并将冗余块分别与下一组k个有效载荷块中的有效负载块相连。在接收端，解码器可以恢复一组k个分组中的p个丢失的分组，该分组具有由下一组k个分组携带的p个冗余块。因此，本发明能够从一行中的多个分组的丢失中进行校正，而不会显着增加数据速率或以其他方式延迟传输。

摘要： A method and apparatus for improving the speed and quality of end-to-end data or real-time media transmissions over an internet is disclosed. A data stream representing a media signal at a given level of compression is processed just before the data stream enters the internet. A less compressed data stream representing the same media signal is generated transmitted through the internet. Due to the lower level of compression, the underlying media signal is less sensitive to packet loss in the internet and, as a result, the media signal that arrives at the receiving end will tend to be more continuous and clear.
摘要翻译：公开了一种通过互联网提高端到端数据或实时媒体传输的速度和质量的方法和装置。在数据流进入互联网之前处理表示在给定压缩水平下的媒体信号的数据流。通过互联网发送表示相同媒体信号的较少压缩的数据流。由于较低的压缩水平，底层媒体信号对互联网中的分组丢失较不敏感，结果，到达接收端的媒体信号往往会更加连续和清晰。

摘要： A method (200) and apparatus for determining whether a network (111) associated with a foreign agent (104) is multiple IP address interface compatible in a mobile node (101) is provided. The foreign agent (104), upon detection of the mobile node (101), composes an agent advertisement (400) that includes one or more flag bits (405). The foreign agent (104) sets one of the one or more flag bits (405) to indicate multiple IP address interface compatibility. Upon receiving the agent advertisement (400), the mobile node (101) configures itself for multiple IP address interface datagram communication. Where the mobile node (101) has not already received a primary IP address (617) from the foreign agent (104), it requests one. The mobile node (101) then requests a secondary IP address (618) from a home agent (103) through the foreign agent (104).

摘要： A computationally simple yet powerful forward error correction code scheme for transmission of real-time media signals, such as digitized voice, video or audio, in a packet switched network, such as the Internet. For each window of k data packets, the invention generates and transmits at least one cross-wise parity packet taken as an index-shifted function over the k data packets. The invention thereby enables a receiving end to recover from packet loss.
