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.

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.
