Abstract: Techniques described herein perform network address translator (NAT) traversal using a peer of a peer-to-peer architecture in lieu of a server. A first peer maintains a list of public domain peers that are not hidden behind a NAT or a firewall and have previously been connected with the first peer. The first peer distributes the list to other peers via a gossip-based protocol. When a second peer desires to connect with the first peer, the second peer initiates a connection with the first peer and sends a request to a public domain peer of the list, requesting that the public domain peer instruct the first peer to initiate a connection with the second peer. By leveraging a public domain peer to establish a connection between the first and second peers, these techniques lessen the burden on the server of the architecture. Furthermore, because different peers may make requests to different public domain peers, the techniques allow for better scalability of the architecture.

Abstract: This document describes a directed graph model using a peer-to-peer overlay structure and a gossip-based protocol to maintain the distributed membership. A protocol suite for peers to join the live streaming session, form the P2P streaming overlay, and exchange video packets with others has also been presented. The different capabilities of the heterogeneous peers are well depicted using an adaptive out-degree mechanism. The performance of the whole system is maintained by a contribution-aware mechanism, which ensures that the peers with large contribution will get more chance to be served than those with small or no contribution.

Abstract: An end-to-end lecture broadcast system (LBS) is described. The LBS system typically comprises three modules: a schedule module, a capture module and a transmission module. The schedule module is comprised of a scheduler that is implemented as a software add-on on the lecture host's computing device, a schedule server, and a schedule agent component in the uploading peer to provide for channel based management. The capture module is comprised of a video camera for capturing video content, one or more microphones for capturing audio content, and a VGA signal capture for capturing presentation materials. The transmission module is comprised of an uploading peer and a web server. The uploading peer is responsible for transmitting video/audio content to the Internet/intranet using peer-to-peer (P2P) streaming technology. The web server is responsible for the delivery of captured presentation materials and for ensuring the synchronous play back of video/audio content and presentation materials.

Abstract: Predicted input data is obtained by initially acquiring a set of operations that are performed on non-editable user interface elements of a user interface prior to a subsequent data input into an editable user interface of the user interface. The set of operations is then classified into a pattern class based on the operations in the set and the subsequent data input that corresponds to the set. Subsequently, a pattern type for the pattern class is generated that describes a relationship between the set of operations and the subsequent data input. Accordingly, when a new set of operations is received, input data is predicted for the new set by applying the pattern type to the new set.

Abstract translation: 通过在随后的数据输入到用户界面的可编辑用户界面之前，首先获取在用户界面的不可编辑的用户界面元素上执行的一组操作来获得预测的输入数据。 然后，基于集合中的操作和对应于该集合的后续数据输入将该组操作分类为模式类。 随后，生成用于模式类的模式类型，其描述操作集与后续数据输入之间的关系。 因此，当接收到一组新的操作时，通过将模式类型应用于新集合来预测新集合的输入数据。

Abstract: Techniques described herein enable peers to determine each peer's NAT type much more efficiently and quickly than when compared with existing techniques. To do so, a peer simultaneously sends multiple test messages to a server. The peer then waits to either receive a response for each of the multiple test messages or may store an indication that no response has been received after a predetermined timeout period. The peer then analyzes the received responses and/or the stored timeout indications to determine the peer's NAT type or to determine that the peer is operating free from concealment by a NAT/firewall device. By simultaneously sending the multiple test messages, the peer may determine the NAT type within a maximum time defined by the predetermined timeout period or a roundtrip time period that is required for communication between the peer and the server. As such, the tools allow for efficient NAT-type detection.

Abstract translation: 本文描述的技术使得对等体能够比与现有技术相比更有效和快速地确定每个对等体的NAT类型。 为此，对等体同时向服务器发送多个测试消息。 然后，对等体等待接收多个测试消息中的每一个的响应，或者可以存储在预定的超时时段之后没有接收到响应的指示。 对等体然后分析接收到的响应和/或存储的超时指示以确定对等体的NAT类型或者确定对等体正在从NAT /防火墙设备的隐藏中运行。 通过同时发送多个测试消息，对等体可以在由对等体和服务器之间的通信所需的预定超时时间段或往返时间周期限定的最大时间内确定NAT类型。 因此，这些工具允许有效的NAT类型检测。
