Edgeware, Skytide ally on CDN monitoring
Edgeware has partnered with Skytide on a product that provides real time analytics for multiscreen services. The system is aimed at CDN operators looking to measure quality of experience (QoE), especially wholesale CDN services where the operator needs to report specific metrics to the wholesale customer.
The two said their system, which combines Edgeware servers with Skytide’s analysis, is currently in use by a number of large CDN customers.
Adaptive bit rate (ABR) streaming detects a user’s available bandwidth in real time and calibrates the video stream accordingly. For ABR to work, a video file is encoded at different bitrates and then divided into fragments. This enables an uninterrupted video experience over unmanaged networks, but it also results in a major measurement challenge. In aggregate over a large viewing audience, one single movie can require analyzing tens of thousands of separate files, the companies explained.
Edgeware said its video servers create a virtual “session” that enables the operator to report usage data tied to sessions and content, not fragments. This reduces the complexity, cost and processing needed to provide accurate, real time QoE reporting to the integration layer, Edgeware said.
Skytide Insight for CDNs can handle the volume and complexity that ABR streaming demands and transform it into reports in real time. This combined solution reduces the traffic and processing overhead from potentially thousands of log entries to one per session resulting in much faster turnaround time in alarms and analytics around QoE.
Skytide is venture-backed and works with leading digital media and technology companies including, British Telecom, Broadpeak, Cisco, Edgeware, Ericsson, Juniper Networks, Tata Sky, Telecom Argentina, Telecom Italia and Telstra.
