摘要： The present invention provides a method, test-bed and computer program product for testing an application installed on a wireless communication device. The wireless communication device communicates one or more messages wirelessly to a server through a test-bed. The test-bed is connected with the server and provides one or more testing parameters for the one or more messages. A tester, testing the application, assigns a probability to the one or more messages. Further, the tester assigns a probability to the one or more testing parameters. Thereafter, the messages are re-communicated between the server and wireless communication device through the test-bed. Subsequently, the one or more messages are identified by the test-bed and one or more wireless network conditions are emulated based on the probabilities assigned to the one or more messages and the one or more testing parameters.

摘要： A method and virtual private network (VPN) system for providing bandwidth guaranteed provisioning in network-based mobile VPN services. The method and system include identifying a set of VPN customers, at least one mobile access point (MAP) and at least one customer premise equipment (CPE) associated with each VPN customer, and at least one Internet Protocol (IP) service gateway (IPSG) for facilitating VPN tunneling between a MAP and a CPE, wherein each MAP is geographically remote from each IPSG. A subset of IPSGs is selected to maximize total profit resulting from provisioning a subset of VPN customers on the selected IPSGs. Total profit from all the customers includes the sum of profits from each customer, where for each customer, the customer profit equals weighted revenue less cost, wherein the cost per customer includes a total tunnel bandwidth cost from the MAP to the CPE, and a cost of provisioning an IPSG node.

摘要： The Fair-Order Service of the present invention delivers action messages to the server as soon as it is feasible. Because action messages from different players exhibit different reaction times with respect to an update message, the Fair-Ordering Service executed at the server dynamically enforces a sufficient waiting period on each action message to guarantee the fair processing of all action messages. In reality, the waiting period at the server is bounded because of the real-time nature of interactive games. The algorithms that offer Fair Ordering Service take into consideration delayed and out-of-order action messages. When action messages corresponding to multiple update messages are interleaved, the Fair-Ordering Service matches the action message to the appropriate update message. It accomplishes this by maintaining a window of update messages and using the reaction times for an action message for each of the update messages in the window. This enables state changes at the game server to be performed with fairness to all the players. The Fair-Order Service invention is based on a framework that uses a proxy architecture making it transparent to any specific game application. The service is well suited to client-server based, online multi-player games, where a fair order of player actions is critical to the game outcome.
摘要翻译：本发明的公平订购服务在可行时尽快向服务器发送动作消息。由于来自不同玩家的动作消息对于更新消息表现出不同的反应时间，所以在服务器处执行的公正排序服务动态地对每个动作消息执行足够的等待时间，以保证所有动作消息的公平处理。实际上，由于互动游戏的实时性，服务器的等待时间是有限的。提供公平订购服务的算法考虑到延迟和无序操作消息。当与多个更新消息相对应的动作消息被交织时，Fair-Ordering Service将动作消息与适当的更新消息相匹配。它通过维护更新消息窗口并使用窗口中的每个更新消息的动作消息的反应时间来实现。这使得游戏服务器上的状态改变能够对所有玩家公平地执行。公平订单服务发明基于使用代理架构使其对任何特定游戏应用程序透明化的框架。该服务非常适合基于客户端服务器的在线多玩家游戏，其中玩家动作的公平顺序对于游戏结果至关重要。

摘要： A system and method of cache replacement for streaming multimedia is provided. A network system includes a content provider connected to local service providers via an interactive distribution network, such as the Internet. The local service providers facilitate delivery of the content from the content provider to multiple subscribers. For each of the data blocks which make up the multimedia stream requested by a subscriber, the local service provider receiving the request determines whether the request can be serviced locally or whether the requested data blocks must be retrieved from the content provider. In the case where the portion of the requested stream must be retrieved from the content provider, the local service provider attempts to cache the requested blocks in its local cache in addition to streaming the data blocks to the requesting subscriber. The local service provider stores two lists to determine which cached block is to be replaced from the local cache memory in the case where the attempt to cache the requested blocks fail because the local cache memory is full. A first list defines those cached blocks for which there are no foreseeable future subscriber requests. The second list defines those cached blocks whose access time from existing suscribers is furthest in the future.
摘要翻译：提供了一种用于流式多媒体的缓存替换的系统和方法。网络系统包括经由诸如因特网的交互式分发网络连接到本地服务提供商的内容提供商。本地服务提供商便于将内容从内容提供商传递到多个订阅者。对于构成用户请求的多媒体流的每个数据块，接收该请求的本地服务提供者确定该请求是否能够在本地服务，或者是否必须从内容提供者检索所请求的数据块。在必须从内容提供商检索所请求流的部分的情况下，本地服务提供商尝试将所请求的块缓存在其本地高速缓存中，除了将数据块流传送到请求的订户。在本地缓存存储器已满的情况下，本地服务提供商存储两个列表以确定要从本地高速缓冲存储器替换哪个缓存块。第一个列表定义了那些没有可预见的未来订户请求的缓存块。第二个列表定义了这些缓存的块，其访问时间从现有的被访问者在将来是最远的。

摘要： A new architecture and operational techniques for supporting high quality live and on-demand streaming multimedia on a data network. By using Helper machines inside the network as data forwarding, caching, and buffering agents, and by forming meshes among Helper machines, advantages of homogeneous, synchronous multicast transmission and of heterogeneous, asynchronous reception are achieved. The architecture provides essentially transparently support to the receivers for near-zero start-up latency, improved playback quality, improved CR-like operations. These are achieved while reducing network and server load compared to today's multimedia networking techniques.

摘要： Layered Video Multicast with Retransmissions (LVMR) is a system for distributing video content using layered coding over the Internet. The two key contributions of the system are (1) improving the quality of reception within each layer by retransmitting lost packets given an upper bound on recovery time and applying an adaptive playback point scheme to help achieve more successful retransmission, and (2) adapting to network congestion and heterogeneity using a hierarchical rate control mechanism. A hierarchical rate control system and method is disclosed for regulating the flow of video information in a network by establishing subnet agents for each subnet, and by establishing intermediate agents for each domain. The subnet agents gather information concerning add-layer experiments conducted by receivers in a subnet, and the information is provided to intermediate agents of the domains for regulating data traffic.

摘要： A real-time, layered video multicast transmission system for transmitting video frames as a stream of encoded video data packets from a sender to one or more receivers over a network, comprises a device for generating one or more independent layers of video substreams out of the encoded video stream, each of the one or more receivers capable of subscribing to one or more layers of the independent video substreams; a device for transporting each of the independent video substreams over the network, the transporting device transporting each substream as an independent flow capable of being received by each of the one or more receivers; a device for monitoring congestive state of the network and the receiver to determine receiver's capability for receiving each of the video substream layer; and a controller provided to enable the receivers to select one or more of the independent video streams in accordance with the congestive state of the receiver. For each layer, a retransmission error recovery scheme is also provided to recover lost packets of the multicast stream based on the congestive status of the receiver.

摘要： A protocol that provides assurance of consistent replication of objects from a server to caching servers, for example, over data communication networks such as the Internet. It is an application-layer protocol which guarantees delivery of objects such as files. This protocol insures that objects sent by a source machine such as a server to any number of destination machines such as caching servers actually arrive at the intended caching servers even when the caching servers are temporarily unavailable, for example, due to failure or network partition.
