摘要： A protocol and methods for peer network device discovery is presented. The peer discovery protocol includes a peer discovery marker than can be used with an existing networking protocol such as Transmission Control Protocol (“TCP”) to discover peer network devices. The peer discovery protocol also includes a peer discovery table to record network addresses of peer network devices and their associated host network devices. The peer discovery method allows a first peer network device such as an edge router, to send out a peer discovery request with the peer discovery protocol to other peer network devices as the peer network device is sending data packets for a host network device. Once a second peer network device receives a peer discovery request, the second peer network device attempts to establish a two-way, peer-to-peer data-flow to the first peer network device that sent the peer discovery requests. The peer discovery protocol and methods allow error correction, encryption, compression and other “intelligent” services to be added to peer network devices such as edge routers. The peer discovery protocol and peer discovery methods may enhance performance, reliability and security of data transmitted over the Internet to and from Autonomous Systems, subnets, or other computer networks.
摘要翻译：提出了一种用于对等网络设备发现的协议和方法。对等体发现协议包括比可以与现有网络协议（例如传输控制协议（TCP））一起使用以发现对等网络设备的对等体发现标记。对等体发现协议还包括对等体发现表，用于记录对等网络设备及其相关主机网络设备的网络地址。对等体发现方法允许诸如边缘路由器的第一对等网络设备在对等网络设备正在发送用于主机网络设备的数据分组时向其他对等网络设备发送具有对等体发现协议的对等体发现请求。一旦第二对等网络设备接收到对等体发现请求，则第二对等网络设备尝试建立到发送对等体发现请求的第一对等网络设备的双向对等数据流。对等体发现协议和方法允许将纠错，加密，压缩和其他“智能”服务添加到诸如边缘路由器的对等网络设备。对等体发现协议和对等体发现方法可以提高通过互联网传输到自治系统，子网或其他计算机网络的数据的性能，可靠性和安全性。

摘要： A system and method for receiving a transported stream of data packets includes a buffer management device for receiving the data packets, unpacking the data packets, and forwarding a stream of data frames. The system and method further includes a first jitter buffer for receiving the data frames from the buffer management device and buffering the data frames, and a second jitter buffer for receiving the data frames from the buffer management device and buffering the data frames. In addition, the system and method includes a computationally-desirable jitter buffer selected from the first jitter buffer or the second jitter buffer by comparing a first jitter buffer quality and a second jitter buffer quality. The system and method also includes a decoder for receiving buffered data frames from the computationally-desirable jitter buffer.

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： 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： 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 media stream being transmitted to the internet is channel coded at the edge of the internet in order to free upstream bit rate for use in source coding the media. The channel coded media stream may then be decoded at a remote edge of the internet to recover lost packets.
