摘要： A fast policy classification method and system. A policy differentiator can be provided which can include a policy repository configured to store hierarchical policy classification trees. The policy differentiator further can include a hashing module configured to produce integer values for string based selector attributes. In one aspect of the invention, the hashing module can include a longest string hashing function. A policy matching engine can be provided which is configured to locate policy rules in the hierarchical policy classification trees according to the integer values produced for the string based selector attributes. Finally, a policy matching engine interface can be provided through which policy queries and resulting policy decisions of the policy matching engine can be communicated between the policy matching engine and the policy enforcement entity.

摘要： Techniques are disclosed that enable an application to prioritize its traffic in an application-specific manner, such that traffic which is most important to this application can be prioritized over traffic that is less important to this application, where this prioritization information is reflected in differential treatment of the traffic within the network. An application conveys relative priority information for its traffic to a Web proxy or edge server, and this device then consults stored policy information to determine how the traffic should be prioritized in the network. The Web proxy also ensures that usage of network resources is balanced among multiple applications. Cookies are used for transmitting priority information between the edge server and application in an efficient manner.

摘要： A computer-implemented method is provided for updating network security policy rules when network resources are provisioned in a service landscape instance. The method includes categorizing network resources in a service landscape instance based on a service landscape model. The method further includes responding to the provisioning of a network resource by automatically generating one or more security policy rules for a newly-provisioned network resource. Additionally, the method includes updating security policy rules of pre-existing network resources in the service landscape instance that are determined to be eligible to communicate with the newly-provisioned network resource so as to include the newly-provisioned network resource as a remote resource based on the service landscape model.

摘要： Embodiments of the present invention address deficiencies of the art in respect to e2e SLA support in a network of both manageable and unmanageable portions and provide a method, system and computer program product for e2e SLA compliance across both managed and unmanaged network segments. In one embodiment of the invention, a method for e2e SLA compliance across both managed and unmanaged network segments can be provided. The method can include identifying both a managed segment and an unmanaged segment of an e2e network for a communications path implicated by an SLA, determining an observed delay for the unmanaged segment of the e2e network, computing from a desired delay for the communications path and the observed delay a differential delay, and constraining the managed segment to meet the differential delay in order to assure meeting the desired delay for the communications path implicated by the SLA.

摘要： Embodiments of the present invention address deficiencies of the art in respect to connectivity management in a heterogeneous network and provide a method, system and computer program product for resilient and reliable end-to-end connectivity in a heterogeneous network. In one embodiment of the invention, a method for resilient and reliable end-to-end connectivity in a heterogeneous network environment can be provided. The method can include creating an instance of an abstracted network resource model (NRM) for a heterogeneous network environment of different network resource nodes. The method further can include binding an application endpoint in the instance of the abstracted NRM with a connectivity endpoint for a first of the different network resource nodes. The method yet further can include detecting an outage in the first of the different network resource nodes. Finally, the method can include re-binding the application endpoint to a second of the different network resource nodes in response to detecting the outage.

摘要： In an embodiment of the invention, a method for secure live migration of a virtual machine (VM) in a virtualized computing environment can include selecting a VM in a secure virtualized computing environment for live migration to a different virtualized computing environment and blocking data communications with the selected VM and other VMs in the secure virtualized computing environment. The selected VM can be live migrated to the different virtualized computing environment and the VM can be restarted in the different virtualized computing environment. Notably, a secure communicative link can be established between the restarted VM and at least one other of the VMs in the secure virtualized computing environment. Finally, data communications between the restarted VM and the at least one other of the VMs can be enabled over the secure communicative link.
