Intelligent predictive stream caching
Some embodiments provide intelligent predictive stream caching for live, linear, or video-on-demand streaming content using prefetching, segmented caching, and request clustering. Prefetching involves retrieving streaming content segments from an origin server prior to the segments being requested by users. Prefetching live or linear streaming content segments involves continually reissuing requests to the origin until the segments are obtained or a preset retry duration is completed. Prefetching is initiated in response to a first request for a segment falling within a particular interval. Request clustering commences thereafter. Subsequent requests are queued until the segments are retrieved. Segmented caching involves caching segments for one particular interval. Segments falling within a next interval are not prefetched until a first request for one such segment in the next interval is received. Cached segments from the previous interval can be replaced in cache with segments for the current interval, thereby minimizing cache footprint utilization. |

Network visibility appliances for cloud computing architectures
With exponential growth in virtualized traffic within physical data centers, many end users (e.g., individuals and enterprises) have begun moving work processes and data to cloud computing platforms. However, accessing virtualized traffic traversing the cloud computing platforms for application, network, and security analysis is a challenge. Introduced here, therefore, are visibility platforms for monitoring virtualized traffic traversing a cloud computing platform, such as Amazon Web Services, VMware, and OpenStack. A visibility platform can be integrated into a cloud computing platform to provide a coherent view of virtualized traffic in motion across the cloud computing platform for a given end user. Said another way, a visibility platform can intelligently select, filter, and forward virtualized traffic belonging to an end user to a monitoring infrastructure, thereby eliminating traffic blind sports. |
