    摘要： An intelligent lookup service for a network is provided for clients of a network requesting services of the network that intelligently determines, based on a service requirement of the requested service, optimal service endpoint(s) for providing the requested service. The intelligent lookup service can incorporate predetermined mapping policy and traffic measurements into the determination. In addition, a feedback loop is provided from clients and/or service endpoints to the lookup service concerning measurements about prior connections in the network. The lookup service can include a set of beacons distributed in the network and against which measurements about the network are recorded. A client receives, from the lookup service in response to a request for a network address, a set of candidate service endpoints that pertain to the requested network address and the client connects to one of the candidate service endpoints based on policy or context.

    摘要： Routing network traffic on a computer network is described. In one embodiment, a method is presented which includes transmitting instructions to a client, the instructions executable by the client to request content from two or more content servers, measure two or more network performance characteristics associated with the two or more different content servers, and issue a report to an administrative server. The report may include a first network performance characteristic and a second network performance characteristic. The method may further include selecting a target content server from one of two or more content servers based on comparison of the two or more network performance characteristics; and transmitting routing instructions to an intermediate routing system, the routing instructions executable by the intermediate routing system to direct subsequent content requests transmitted by the client to the target content server.

    摘要： Because it is difficult to provide adequate quality of service to large-bandwidth calls in integrated-services networks, service providers may allow some customers to book ahead their calls. The present invention provides a scheme resource sharing among book-ahead calls (that announce their call initiation and holding times upon arrival) and non-book-ahead calls (that do not announce their holding times and enter service immediately, if admitted). The basis for this sharing is an admission control algorithm in which admission is allowed if an approximate interrupt probability (computed in real time) is below a threshold. Simulation experiments show that the proposed admission control methodology is superior to alternative schemes that do not allow interruption, such as a strict partitioning of resources.

    摘要： Disclosed is a method and system for optimizing a first set of rules enforced by a firewall on network traffic. Characteristics of the network traffic are examined and these characteristics are used to generate a second set of rules. The first set of rules may have a different order than the second set of rules.
