摘要： Disclosed are embodiments of a security system for reducing data leaks by checking information flows between resources of a network. When an information flow is attempted between a sending resource, which can be anywhere in the network, and a receiving resource residing at a specific host within the network, a host labeler can determine whether information is allowed to flow from the sending resource to the receiving resource. The sending resource and the receiving resource can each have an applicable label, and each label can comprise zero, one, or more taints. For each taint having an active secrecy characteristic in a label of the sending resource, the host labeler can require that there be a matching taint with active secrecy characteristic in the receiving resource. If this condition is not met, the security system can block the information flow between the sending and receiving resources.
摘要翻译：公开了通过检查网络资源之间的信息流来减少数据泄漏的安全系统的实施例。当在可以在网络中的任何地方的发送资源和驻留在网络中的特定主机的接收资源之间尝试信息流时，主机标签器可以确定是否允许信息从发送资源流向接收资源。发送资源和接收资源可以各自具有适用的标签，并且每个标签可以包括零个，一个或多个图案。对于在发送资源的标签中具有主动保密特征的每个污点，主机标签器可以要求在接收资源中存在具有主动保密特征的匹配污点。如果不符合条件，则安全系统可以阻止发送和接收资源之间的信息流。

摘要： The present invention pertains to specifying, analyzing and evaluating systems such as distributed content distribution networks. Systems and methods are provided to predict how new deployments and changes to existing architectures will impact the networks. A network design may prepare a “what-if” scenario and the impact of this scenario may be predicted. Various tools are provided to determine relevant network variables and collect data about such variables, to learn what dependencies may exist among relevant variables, to prepare an input distribution and to output a predicted impact for the what-if scenario. Thus, a system designer is able to see a predicted impact that a network change or new deployment will have without having to resort to back of the envelope calculation or costly field deployments.
摘要翻译：本发明涉及诸如分布式内容分发网络的系统的指定，分析和评估。提供系统和方法来预测现有架构的新部署和更改将如何影响网络。网络设计可能会准备一个“假设”情景，并且可以预测这种情况的影响。提供各种工具来确定相关的网络变量并收集关于这些变量的数据，了解相关变量之间可能存在的依赖关系，以准备输入分布并输出预测的影响。因此，系统设计人员能够看到网络更改或新部署将具有的预期影响，而无需诉诸于信封计算或昂贵的现场部署。

摘要： In a network, a router uses some secret information combined with a cryptographic process in determination of a subnet's routing prefix. Several methods are disclosed, including using an IP suffix for prefix generation and for decryption, maintaining a pool of pseudo prefixes at the router, using public key encryption and symmetric key encryption.

摘要： A cache handoff system for managing cacheable streaming content requested by a mobile node within a network architecture is disclosed. The network architecture includes a first subnet and a second subnet. The cache handoff system includes a first caching proxy operable in the first subnet to supply a content stream in response to a request of the mobile node operable in the first subnet. In addition, the cache handoff system includes a second caching proxy operable in the second subnet. The first caching proxy may initiate a cache handoff of the request to the second caching proxy when the mobile node relocates to the second subnet. The second caching proxy may seamlessly continue to supply the requested content stream as a function of the cache handoff.
