摘要： A data streaming transmission method and system is disclosed having a network server connected to client device through a communication network with one or more of caching servers. The network server has a data streaming application and a memory for storing data. A series of connections, each using a data streaming arrangement, is formed in the path between the source network and client device by the caching servers. Each caching server can absorb network congestion in its downstream connection by utilizing an expandable buffer for storing additional segments of the streamed data and varying the transmission data rate in the down stream connection.

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.
摘要翻译：一种协议，提供对象从服务器到缓存服务器的一致复制的保证，例如通过诸如因特网的数据通信网络。它是一种应用层协议，保证诸如文件之类的对象的传送。该协议确保由诸如服务器之类的源计算机发送到任何数量的目的地机器（例如缓存服务器）的对象实际上到达预期的缓存服务器，即使缓存服务器暂时不可用，例如由于故障或网络分区。

摘要： Client's (106-1-106-N, 107-1-107-M) on local area networks (102, 103) making requests to hot sites, which are connected on a wide area network (100) such as the Internet, are redirected through one of a possible plurality of different redirectors (101, 103) to one of a possible plurality of caching servers (S1, S2, S3), which each have responsibility for mapping one or more of the hot sites. Each request is probabilistically directed by one of the redirectors to one of the caching servers that map the requested hot site in accordance with weights that are determined for that redirector-hot site pair so as to minimize the average delay that all client requests across the network will encounter in making requests to all the cached hot sites. In order to determine the weights with which each redirector will redirect requests to the hot sites to the caching servers, statistics of access rates to each hot site are dynamically determined by each redirector in the network from the traffic flow and reported to a central management station (CMS) (115). Network delay is similarly measured by each redirector and reported to the CMS, and server delay is computed using a queuing model of each server. Using these parameters as inputs, a non-linear programming optimization problem is solved as a network flow problem in order to determine the weights for each redirector that will minimize the average delay. As the access rate statistics, as well as the network delay and server delay, dynamically change, the CMS, using the network flow algorithm, recalculates the weights and forwards them back to each redirector. In other embodiments, the redirector-logical item pair for which the redirector probabilistically directs client requests may be other than a hot site identity. For example, the logical items can be groups of clients or groups of documents, and the servers to which requests are forwarded can be web servers or caching servers.

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： 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.
