摘要： A method and apparatus for identifying virtual private networks (VPNs) in a network of a service provider. The method and apparatus includes generating a VPN routing forwarding—route target (VRF-RT) table for the network. From the VRF-RT table, at least one of a VRF-VRF table and a VRF connectivity graph is generated. From the VRF-RT table, a set of atomic full-mesh components are identified, and from the at least one of a VRF-VRF table and a VRF connectivity graph, at least one set of other types of VPN components are identified, such as atomic single hub-and-spoke components, molecular multi-hub-and-spoke components, composite full-mesh components, composite single hub-and-spoke components, and/or composite multi hub-and-spoke components.

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： The invention includes a method and apparatus for synchronizing an asset within application space. The method includes receiving asset information comprising an original position of the asset within application space on a sending system and a trajectory of the asset within application space on the sending system, and determining an updated position adapted for placing the asset within application space on a receiving system, wherein the updated position is determined using the original position, the trajectory, and an expected propagation delay from the sending system to the receiving system. The expected propagation delay between the sending and receiving systems is determined by one or more network proxies. The original position and trajectory of the asset may be received in a data structure which may be modified to include the updated position for use by the receiving system in placing the asset within application space on the receiving system.

摘要： A method and apparatus for providing at least two virtual private network VPN tunnels from a client device in a VPN network having an enterprise gateway and a network VPN gateway. The method and apparatus includes a client device having an Internet Key Exchange (IKE) module for establishing the at least two tunnels using an IKE protocol wherein a first tunnel is an end-to-end VPN tunnel to the enterprise gateway, and a second tunnel is a network-based tunnel to the network VPN gateway. An IPsec Network Driver Interface interfaces with the IKE module, which includes a security authentication database (SADB) that stores downloaded enterprise security policies respectively for each of the at least two tunnels. A routing table stores IP addresses of local presences and hosts respectively associated with the at least two tunnels, whereby packets are routed over the at least two tunnels based on the downloaded policies.

摘要： A method and apparatus for providing user specific request redirection in a content delivery network includes parsing a page having embedded objects intended for redirection to at least one cache server, and transforming the embedded objects into relative uniform resource locators (URLs). A content-base token is inserted into an HTTP response header in response to a user request for the page. In an instance where the content-base token is not supported by the server and/or client devices, a base token is inserted into the page in response to a user request for the page. The content-base token and base token provide identification of a server or URL prefix where the embedded objects in the page are to be retrieved. The requested page is then sent to the user's browser. The browser constructs absolute URLs from the embedded URLs using either the received content-base token or base token, to retrieve embedded objects from the server.
