摘要： Several deterrence mechanisms suitable for content distribution networks (CDN) are provided. These include a hash-based request routing scheme and a site allocation scheme. The hash-based request routing scheme provides a way to distinguish legitimate requests from bogus requests. Using this mechanism, an attacker is required to generate O(n2)amount of traffic to victimize a CDN-hosted site when the site content is served from n CDN caches. Without these modifications, the attacker must generate only O(n) traffic to bring down the site. The site allocation scheme provides sufficient isolation among CDN-hosted Web sites to prevent an attack on one Web site from making other sites unavailable. Using an allocation strategy based on binary codes, it can be guaranteed that a successful attack on any individual Web site that disables its assigned servers, does not also bring down other Web sites hosted by the CDN.

摘要： Content delivery by a network node is optimized. The network node is communicatively coupled between multiple end user devices and at least one content service provider. A request for a media streaming service available from the content service provider is intercepted from a first requestor device. It is determined if the media streaming service is registered for delivery optimization based on at least one service rule specific to the media streaming service. It is determined if a second requestor device is currently receiving the media streaming service from the content service provider. In response to the media streaming service being received by the second requestor device, delivery optimization of the media streaming service is performed by replicating the media streaming service for delivery to the first requestor device. The replicated media streaming service is sent to the first requestor device.

摘要： A computer-implemented method, system, and program product for optimizing a distributed (software) application are provided. Specifically, a configuration of a target computing environment, in which the distributed application is deployed, is discovered upon deployment of the distributed application. Thereafter, based on a set of rules and the discovered configuration, one or more optimization techniques are applied to optimize the distributed application. In a typical embodiment, the set of rules can be embedded in the distributed application, or they can be accessed from an external source such as a repository. Regardless, the optimization techniques applied can include at least one of the following: (1) identification and replacement of an underperforming component of the distributed application with a new component; (2) generation of interface layers (to allow selection of optimal bindings) between distributed objects of the distributed application; and/or (3) execution of code transformation of the distributed application using program analysis techniques.
